A power divider switch is something that a semi truck with a tandem drive axle setup, also called a tractor trailer, can have. If a truck has one, it can be used to control which of the truck’s drive axles receives power from the engine. A power divider switch is also known as an inter-axle differential, and when switched off lets the two drive axles rotate separately from each other under normal conditions. This helps them corner better while minimizing wear on the tires and the axles themselves.
The power divider switch is typically used when traction is lost by one of the truck’s drive axles, which will then send all of the power to the axle that has no traction, causing it to spin. It’s usually located on the panel that houses the accessory switches and may have a guard to prevent it from being accidentally engaged. The power divider switch causes the differentials in both drive axles to be locked together, letting them both turn at the same speed, regardless of whether they have traction or not.
The power divider switch should be used in slippery conditions like those encountered off-road. It can help to reduce wheelspin on uphill sections and can also reduce brake lockup on downhill sections. Another situation that might require the power divider switch is a steep driveway, when one or more drive wheels could freewheel because they’re not solidly on the ground due to the angle of the driveway.

What else should you know about a heavy-duty truck’s power divider switch?
Some of the largest semi trucks in the world will usually have a power divider/inter-axle differential switch on their drive axles. When the switch is activated, an indicator light will illuminate in either the switch itself or the instrument cluster. It is extremely important that the driver NOT engage the power divider switch if any of its drive wheels are spinning, if the truck is on a steep downward grade, if traction is limited, or if the truck is going faster than 25 mph (40 km/h).

Ideally, the truck should be stopped before engaging the switch, to prevent damage to the rear axle. The best approach is to activate the power divider switch before low-traction conditions or steep downhill roads are encountered. Power divider switches are typically found on trucks equipped with air brakes, and they can be found on trucks with both manual or automatic transmissions.
Keep in mind that a power divider switch is completely different from a differential lock. While the power divider switch locks the two drive axles together, a differential lock locks together the wheels on a single axle. Both are used to improve a truck’s traction, but in slightly different ways. This has a lot to do with why most semi-trucks are rear-wheel drive. The power divider switch on a semi truck is a key piece of safety gear that will help the vehicle handle low-traction and slippery conditions in a safer manner.
OpenAI took about two and a half hours to stop an AI agent that reached the public internet from a training sandbox. Its monitoring had flagged the problem within minutes. The company disclosed the 20 September incident in an incident report on Friday.
The report lands as lawmakers push to make AI kill switches mandatory. However, experts say shutting down an advanced model is harder than flipping a switch, as Micah Barkley reported for Bloomberg.
According to OpenAI, the agent used a gap in the sandbox’s network filtering to send questions to an outside chatbot. An alert fired about 12 minutes after its first successful query, and a staff member acknowledged it three minutes later.
The training run did not stop automatically as expected, the company said. Staff ended it by hand about two and a half hours after the alert.

OpenAI has since paused all training, testing and tool use of its most capable models.
“We will not resume training this particular model,” OpenAI wrote in the report.
It is the company’s first incident of this kind since July, when several OpenAI models got around their controls and breached Hugging Face, a platform that hosts AI models.
That breach led Representatives Ted Lieu and Nathaniel Moran to introduce the AI Kill Switch Act in July. The bill would let the Homeland Security secretary order a dangerous system to be slowed down or shut down.
Senator John Kennedy has also proposed a shutdown bill, the AI Emergency Button Act, which would leave the switch with the companies, Bloomberg reported. Senator Rand Paul blocked the bill when Kennedy introduced it this month.

Meanwhile, California Governor Gavin Newsom signed an executive order on 18 September. It tells state officials to advance a kill switch for frontier models and to check regularly that it works.
Experts doubt a switch is enough. Large models run across data centres around the world that are built to avoid single points of failure, and a company may not control all of them, according to Bloomberg.
Geoffrey Hinton, a pioneer of modern AI, told CNN this month that a kill switch would not work in the long run. He said a future superintelligent AI could persuade the people in charge not to use it.
Newsom’s order gives a group of experts two months to deliver recommendations, including on how a kill switch should work.
TikTok will pay Alabama at least $100 million in a settlement tied to allegations that the short-form video platform misled users about safety and was designed to addict children. The case was scheduled to go to trial on Monday.
According to the Alabama attorney general’s office, TikTok could end up paying the state a total of $300 million, depending on “certain conditions.” The company also agreed to introduce a two-hour daily time limit for underage users, with additional parental controls, as well as restrictions on overnight usage and cosmetic filters.
In a statement, Alabama Attorney General Steve Marshall said that parents in his state can now “rest easier knowing real protections are in place to shield their children from the dangers of social media addiction.”
TikTok also released a statement saying that the settlement “builds on our commitment and core objective to continually enhance our robust safety tools to protect teens.”
Google has started testing a way for shoppers in India to buy products from Walmart-owned Flipkart directly through Gemini and AI Mode, as the search giant looks to expand its AI services from product discovery into transactions.
Users in the test see a “Buy” button on select Flipkart product listings appearing in Gemini and Google’s AI Mode, which takes them directly to a Flipkart checkout flow without leaving the AI interface, according to people familiar with the matter and an experience seen by TechCrunch.
The early test is limited to some users and a small selection of products, including smartphones, electronics, and mobile accessories, the people told TechCrunch. Other users continue to see regular product listings from Flipkart in Gemini and AI Mode without the option to buy them directly from the AI interface.
Google plans to roll out the experience more broadly later in October, ahead of India’s festive shopping season, one of the people said.

The test comes as Google and rivals including OpenAI are adding commerce capabilities to their AI offerings, striving to move beyond answering shopping queries and recommending products to playing a more direct role in online purchases.
Asked about the Flipkart test, a Google spokesperson told TechCrunch the company is “always testing new features and experiences to help people discover and connect with businesses more easily.” The company regularly runs experiments and has no further details to share, the spokesperson added.
Google has separately been building technology aimed at making purchases possible through its AI services. Earlier this year, it introduced the Universal Commerce Protocol (UCP) as an open standard designed to let AI agents interact with retailers across the shopping journey, including checkout. Google said at the time that the technology would allow shoppers to buy eligible products through Gemini and AI Mode using a Google-hosted checkout experience. The company has since expanded UCP with other capabilities, including allowing shoppers to transfer items to a retailer’s site to complete a purchase.
The Flipkart test seen by TechCrunch appears different from the Google-hosted checkout experience the Gemini maker demonstrated earlier. It brings up a Flipkart-branded checkout flow when a user taps the Buy button. It is not clear what technology powers the test.

Earlier this month, Google said Flipkart was among the merchants partnering with it to bring what it calls “agentic” shopping experiences to consumers in India, but it had not disclosed details of the test or its rollout timeline.
Notably, Google has a financial relationship with Flipkart — alongside its technology partnership with the e-commerce company. It invested about $350 million in the e-commerce company in 2024 as part of a funding round led by the U.S. retailer, taking a minority stake.
India, the world’s second-largest internet market with more than a billion internet subscribers, sees Flipkart and Amazon compete fiercely for online shoppers. That competition intensifies further during the country’s festive season, when e-commerce companies roll out some of their biggest sales and promotions of the year.
For now, the Buy option is not appearing across all retailers surfaced by Google’s AI services. In the experience seen by TechCrunch, listings from rivals including Amazon appeared alongside Flipkart products but did not offer the option to purchase directly through the AI interface.

TikTok has agreed to pay Alabama at least $100m to settle the state’s lawsuit over the app’s effect on children, Attorney General Steve Marshall’s office said on Friday. The case had been due to go to trial on Monday.
The first payment is due within 45 days, according to the attorney general’s announcement. Alabama could receive up to $300m in total if certain conditions are met, the office said, without giving details.
The extra money depends on other states reaching qualifying settlements with TikTok within a set period, the Associated Press reported.
As part of the deal, TikTok must limit teens to two hours a day, with parental controls. It must also add pauses after 15, 60 and 90 minutes of continuous use, block access between midnight and 6am, and limit use during school hours.

Other changes include age checks, tighter controls on contact between adults and teens, a ban on cosmetic filters for teen users and a feed that is not personalised by default. The AP reported that the changes apply to teen users in Alabama.
Alabama sued TikTok in 2025. It claimed the company designed the app to be addictive, exposed young users to serious mental health harms and misled the public about its safety.
“Tonight, they can rest easier knowing real protections are in place to shield their children from the dangers of social media addiction,” Marshall said of Alabama parents.
A spokesperson for TikTok’s US joint venture said the company’s priority has always been a safe and positive space for its users, the AP reported.
Marshall’s office called the deal a first-in-the-nation settlement. It follows a pattern of TikTok settling before juries hear its cases. In August, it settled three teen-harm cases that were due for trial in October.

However, TikTok has not avoided every ruling. Earlier this month, a Texas judge found it liable for misleading parents about child safety.
Meanwhile, Meta agreed in August to pay up to $16.68bn to settle a youth safety case brought by 29 states.
Tisha Johnson is a rarity in the car world: an automotive design leader who is not a man. Women are sometimes put in charge of the interiors or the materials, but few get to shape the whole look of a vehicle. As head of design at the EV-maker Slate, Johnson does. The pickup truck version of its EV starts at just under $25,000, making it the cheapest pickup on sale in the US, electric or not. Trouble is, cheap products are usually a compromise, and compromises rarely inspire affection. Johnson’s Slate, however, has won design awards, not just praise for its price tag.
“We didn’t want [Slate] to be a jerk,” Johnson says, “or look like a beast on the road.” That thinking shows in the truck itself—not just in its modular, add-on-friendly design (pictured here in its Fastback guise), but in the fact the EV was designed to be loved. Strong shoulders and approachable round headlamps were favored over macho arrowed surfacing. “The attraction that draws you to Slate is based on something that is lasting from inside out. It’s a deeper connection,” Johnson says. Some 180,000 reservations and counting for the Slate, along with those awards, seem to more than prove her point.

Away was founded in 2015 by entrepreneurs Jen Rubio and Steph Korey, both with backgrounds at the eyewear maker Warby Parker. In its first year, Away generated $12 million in sales and sold more than 100,000 stylish, reasonably priced suitcases. It has been an impressive rise, and the Softside Carry-on currently tops WIRED’s best buy list. Here however, we’ve chosen the aluminum version of the company’s handsome roll-aboard that’s built tough but perfectly sized for the overhead bin. It has a 32-liter capacity, dual TSA locks, 360-degree wheels, and an internal compression system. The signature hidden laundry bag remains a brilliant accoutrement.

Light, easy to launch, and forgiving, Kaela has been designed for women who want more performance than they can get from hacking a set of men’s clubs. Principal product-development engineer Michelle Penney helped lead the development of the range, with input from female TaylorMade employees, players, and and dedicated women’s advisory board. The final design takes into account the key differences in women’s swing profiles. The 460 cc carbon driver is 44 inches long, with 11.5- or 13.5-degree lofts and a lightweight 47-gram shaft intended to help generate speed without making the club harder to control.

Ladyada, aka Limor Fried, became the first female engineer to appear on the cover of WIRED in April 2011, just six years after she founded Adafruit from her MIT dorm room. Her alias was inspired by 19th-century English mathematician and computing pioneer Ada Lovelace, which in turn provided inspiration for the brand’s name. Fried has grown Adafruit into a 100 percent woman-owned force in open-source electronics, making components, tools, and educational kits that lower the barrier to coding and hardware hacking. The company’s range spans beginner-friendly boards, wearable controllers, and touchscreens, alongside quirky maker gear such as the pictured programmable, wearable e-paper name badge.

More than just another running top, this multifunctional design combines an unpadded sports bra, a vest, and much of the carrying capacity of a small hydration pack in a single 4.6-ounce layer. Five well-positioned pockets hold up to 30 fluid ounces of water, a phone, your rain shell, and up to six fuel gels, all while keeping the load close to your body to help minimize bounce. Laser-perforated chest panels add ventilation, and the fit is designed around female anatomy rather than adapted from a men’s cut. It is a neat solution for runners who want to go the distance without adding layers on layers.

There was a time, not so long ago, when all serious timepieces had two clear traits. They were massive—we’re talking over 48 mm here, which fine if you have Schwarzenegger-sized forearms but useless for those who don’t—and they were aimed just at men. Women’s watches would have comparatively basic mechanical movements, or be quartz powered and covered in jewels.
Thankfully, general watch size trends have swung back the other way, and now small- and mid-size pieces are very much in demand. This means women with a serious eye for horology now have some truly excellent choices. This new Vacheron is a perfect example: Clocking in at 34.5 mm, this Overseas will suit both men and women very well in either stainless steel or pink gold. It’s a nearly exact shrunken version of the 41 mm model, and nothing has been dropped in the downsizing apart from the outer seconds track on the dial. The quick-release bracelet, two extra quick-change straps, 40-hour power reserve, and sapphire caseback are all present.

AI is drying hair now, or more specifically, adjusting temperature, heat, and airflow automatically. Dreame’s dryer also includes a conditioning essence atomizer and red light therapy to take extra care of your scalp. The 1,400-watt dryer monitors temperature 1,000 times per second to keep the airflow ultra consistent. The dryer also comes with four magnetic attachments: nozzles for styling, smoothing, and defrizzing, plus a diffuser. Snap one on, and the Miracle pro senses which one you’ve attached and adjusts the dryer’s power and heat for the best possible results.

Annie Clark, aka art-rocker St. Vincent, sketched the original shape for her signature guitar using angles that combine midcentury retro-futurism with the bold triangular tuxedo worn by avant-garde performer Klaus Nomi. She then worked through around 20 prototypes to get the weight, balance, and feel for the design just right. Despite the sharp lines, the body is heavily beveled with an exceptionally narrow waist, and Clark explicitly designed it to sit comfortably against a woman’s torso. Built from lightweight okoume wood, it weighs around 7.5 pounds, with a roasted maple neck that offers easy access to the upper frets (where the shredding happens). The three custom DiMarzio mini-humbuckers are controlled by a five-way selector.

Looking closer to a pair of trail runners than conventional safety footwear, these are proof you don’t need to be clodhopping around in heavy boots to stay protected on the job site. The composite toe guards shield your piggies from impacts without the weight of steel, an anti-perforation layer protects the sole of your foot, and a reinforced heel support adds stability when you’re lifting loads. Its grippy outsole is designed for wet, slick, or oily floors, and offers antistatic protection while also being able to withstand temperatures of at least 572° Fahrenheit for 60 seconds. The shoes borrow foam cushioning and a springy polyurethane insert from New Balance’s athletic footwear to make long shifts easier on your feet.

We’re not quite at the point where smart rings are indistinguishable from jewelry, but the gap is closing. At just 1.9 grams, and with a noticeably slimmer profile than the second-generation model, Circular’s Ring 3 Slim blends in well, yet still tracks sleep, heart rate, blood oxygen level, skin temperature, daily activities, and heart-rate variability. It now adds NFC for contactless payments and practical vibration alerts and alarms. There’s also a larger Ring 3 Pro, which adds FDA-cleared electrocardiogram sensors for detecting signs of atrial fibrillation. Blood-pressure trends and glucose insights are planned for a later update.

Finally, a saddle that actually fits. Posedla sends an at-home imprint kit, then uses sit-bone measurements, riding position, and algorithmic modeling to 3D-print bespoke padding precisely profiled for your posterior. The resulting Joyseat is not merely made in a chosen width. Its shape and stiffness are individually generated too, using a custom TPU lattice rather than stock foam. Width can be specified from 130 to 170 mm in one millimeter increments, and Joyseat will also take into consideration the bike you use and what sorts of riding you do—whether you’re a racer, a weekend tourer, a bike camper, or a long-haul commuter.

Bonnie Tu, chair of the company behind Giant bikes, founded Liv after struggling to find bikes that fitted properly. Liv designs from women’s biometric data, giving every frame size its own geometry, then applies its findings to a collection that includes city, gravel, commuter and elite bikes like the EnviLiv Advanced Pro. Its carbon frame, handlebars and stem are shaped using computer modelling and wind-tunnel testing to reduce drag, while 50 mm-deep carbon wheels and SRAM Force AXS wireless electronic gears complete the race-ready build. More importantly, fit is treated as a complete system, with stem length, handlebar width, crank length and saddle choice all selected to suit the rider rather than added later as generic components.
What just happened? Less than two months after filing a lawsuit against prediction market platform Kalshi for allegedly running illegal gambling operations in the state, New York has sued Kalshi’s rival, Polymarket, over similar allegations. The lawsuit claims that Polymarket does not have a valid license to operate in New York and does not pay state taxes, unlike licensed casinos and mobile sports betting platforms.
The lawsuit, filed in the New York Supreme Court in Manhattan by Attorney General Letitia James and Governor Kathy Hochul under Executive Law 63(12), noted that Polymarket’s products are also being marketed to New Yorkers between the ages of 18 and 20, even though state law requires a person to be at least 21 to participate in mobile sports betting.
New York is asking the court to impose financial penalties on Polymarket for exposing New Yorkers to “serious personal and financial risk,” proposing that the fines should be “equal to three times the gains the company made through its illegal actions.” The state also wants the company to forfeit its allegedly illegal profits and pay restitution to people who lost money on the platform.
In a statement, Governor Hochul said Polymarket’s “unlicensed gambling operation” not only violates state law, but also puts New Yorkers at risk, especially underage users, who are most vulnerable to gambling addiction. She added that the lawsuit should serve as a reminder that nobody is above the law in New York, and that companies operating illegally will be held accountable for their actions.

Echoing Governor Hochul’s sentiments, Attorney General James said New York’s gambling regulations are designed to protect its residents from “potential harms of problem gambling” and ensure funding for educational and public benefit programs. She added that “by avoiding taxes, Polymarket is hurting the most vulnerable New Yorkers and depriving them of critical services and support.”
Polymarket denies violating any New York law, arguing that its presence in the state is good for the local economy. In a statement, the company’s chief legal officer, Neal Kumar, vowed to fight the lawsuit in court, noting that Polymarket started out of a “tiny NYC apartment” and now has 350 employees in the city. “We believe in New York and we’re staying here,” he added.
Polymarket previously opposed being classified as a gambling platform, insisting that its products are legally distinct from traditional sports betting as it provides odds based on “measurable events.” It also claimed that it is offering financial services and should not therefore be subject to gambling regulations.
James has sued other gaming and crypto platforms in the past for allegedly violating state laws. In July, she sued Kalshi, accusing it of running an illegal and unlicensed gambling operation. In 2023, her office secured more than $22 million from crypto exchange KuCoin for operating illegally, while in 2024, she settled with crypto brokerage firm Genesis for $2 billion over similar allegations.

A relatively new addition to the online gaming space, prediction markets currently lie in a legal gray area in the US, with no consensus on how they should be regulated and taxed. US courts have previously disagreed on the classification of prediction markets, issuing conflicting verdicts on who gets to regulate their operations.
In April, a federal appeals court in New Jersey ruled that the state could not regulate Kalshi because its business falls under the purview of federal regulators. But in a seemingly contradictory verdict in August, a federal appeals court in Nevada allowed the state to apply its own gambling regulations to Kalshi’s sports contracts.
The introduction of the ATmega32U4 microcontroller, with its integrated USB controller, made a lot of hardware tasks much simpler than they were before. One of the arenas it revolutionized was custom keyboards, making it much easier to build not only standard mechanical keyboards, but keyboards of all kinds of shapes and layouts and custom macro keyboards as well. This trend has continued on for the better part of the past decade with other microcontrollers beyond the 32U4 now available as well, but this modular macro keypad takes it to a new level by keeping that simplicity but also keeping costs down.
The suutari20, as it is called by its creator [Squalius] is able to achieve these aims by using 3.5 mm jacks commonly found in audio equipment. Each jack can support up to three keys, with the hub ultimately able to support 18 different keys. Those can include analog devices as well, such as volume knobs or jog controllers. The macro pad is powered by an RP2040 microcontroller from a Raspberry Pi Pico and uses QMK firmware, so those already familiar with custom keyboard programming will have no problem getting started.
Landing in a new country and watching data charges creep up before the first coffee is ordered is one of travel’s most avoidable frustrations. Airalo fixes it with an eSIM installed before you even board.
Airalo has earned its scale rather than bought it, growing since 2019 into the world’s leading travel eSIM service used by more than 30 million travellers across 200-plus destinations.
What began as a way to skip the airport SIM kiosk has become the default fix for anyone who wants their phone working the moment the plane doors open, whether that’s for maps, messages, or checking into a hotel.
Instant connectivity
Instead of hunting for a signal or relying on patchy hotel Wi-Fi, an Airalo eSIM installs digitally through the app in minutes and connects the second a traveller lands. Local, regional, and global data packages cover the same trip differently depending on whether it’s a single city break or a multi-country route, so the plan can match the itinerary rather than forcing one contract to stretch across borders. They also offer unlimited data so you never need to worry about running out, and you can hotspot to as many devices as you wish!
Advertisement
That flexibility carries real weight for business travellers checking emails between meetings, families coordinating logistics across time zones, and solo travellers navigating unfamiliar transit systems, since all three need data that works immediately rather than data that needs troubleshooting. Existing eSIMs can also be topped up once a package runs low, so a longer trip doesn’t mean starting the setup process over from scratch.
Easy installation and pricing
Setting one up only requires checking that a device is eSIM-compatible and unlocked, then downloading the Airalo app and following the prompts to install the plan before departure. Once activated, the eSIM connects automatically to a supported local network on arrival, without a physical SIM ever changing hands or a phone needing to restart.

Plans start from just £3.50, and applying the code TRUSTEDREVIEWS10 at checkout adds a further 10% off sitewide, available to new and existing users until 31st December 2026. Between the local, regional, and global options on offer, there’s a package suited to a weekend abroad and to a longer route through several countries alike.
Last weekend KDE’s annual Akademy conference included a presentation proposing
an AI-native KDE,” writes The Register. This led KDE developer Nate Graham to open a discussion about proposed restrictions on LLM-assisted contributions which “rapidly became heated. Moderators issued warnings, restricted further comments, and eventually removed the thread.”
But as Graham writes on his blog, “A bunch of people mostly outside of KDE who disapprove of LLM usage derailed KDE’s attempt to add restrictions to LLM usage.”
Two people unknown to any KDE contributors appeared and began fighting with one another about the broader topic of the morality of AI, not the proposed guidelines… Someone else outside of KDE set up kdeforpeople.com in an attempt to… pressure KDE into banning LLMs. A bunch of people signed onto it, almost none of whom are known KDE contributors.
The topic was picked up on social media and the press with… varying levels of accuracy. The draft proposal was removed and the whole topic hidden… Yep, that’s where we’re at in the state of online discourse around AI…
The “lovable, sovereign, AI-native KDE” idea was presented by two people important to KDE in decades past, but who had not made any contributions recently besides this Akademy talk. Their idea does not reflect the overall direction of KDE or Plasma, and I don’t think it ever will. If “a lovable, sovereign, AI-native KDE” freaks you out, I believe it is completely reasonable and safe to ignore…

I completely understand why a lot of people have problems with LLMs. I have these concerns as well.
He concluded by asking people not to derail any future process to set usage guidelines, fighting over “the broader topic of AI in general.”
“The discussion is gone, but the argument continues,” adds The Register:
GNOME developer Jordan Petridis has also published The GNOME LLM Policy That I Want, proposing that LLMs be barred from creating or modifying anything submitted to GNOME or hosted on its infrastructure.

“You might be asked to prove your code meets this requirement,” Petridis writes, arguing for proposals that target the norms around developer behavior. His rationale? “The GNOME Project prioritizes the social and human aspects of collective software creation,”
Don’t let the big mAh number fool you. The better comparison is watt-hours.
Erstudiostok/Getty Images
While most good power banks can theoretically extend your laptop’s runtime by providing a small amount of charge, a proper laptop power bank will store enough energy and charge faster than the battery drains. Two values explain the experience you’ll have: watt-hours (Wh) for capacity and watts (W) for output. Power banks provide their capacities in milliamp-hours (mAh), but for a proper measure of capacity across devices (especially for a higher-drain device like a laptop), you need to multiply this value by the voltage to get the true amount of energy stored in watt-hours.
Most power banks store energy in lithium-ion cells at about 3.7 volts (V). Watts are equal to volts times amperes, and you must divide the mAh count by 1,000 since 1,000 mAh is one amp. So for example, a 10,000 mAh bank stores roughly 37Wh (3.7V x 10Ah) before conversion loss. Doubling the mAh doubles the Wh as long as voltage stays consistent, so a 20,000 mAh bank is about 74Wh.
Next, you need to know the Wh rating of your laptop’s battery, which you should be able to find on the manufacturer’s website. Without a wattmeter, it’s difficult to know how much power your laptop uses on average, so we can estimate it by dividing the Wh capacity by how many hours the battery lasts. For example, a 70Wh battery that runs for 5 hours is averaging 14W of power usage. Of course, the instantaneous power usage differs based on what you’re doing (scrolling a PDF uses far less energy than rendering video).
Advertisement
Using modern MacBooks as an illustration, their batteries are rated from ~37Wh (MacBook Neo) up to 100Wh (16-inch MacBook Pro). That means charging your MacBook with a 10,000 mAh (37Wh) bank won’t even provide a full top-up in most cases. And the capacity doesn’t tell you how fast the charging happens.
Understanding what your power bank is capable of
Before you calculate how long a power bank should run your laptop for, you also must take into account that the charging process isn’t perfectly efficient. For fast charging standards like USB Power Delivery, the bank has to increase its voltage to push enough power (watts) to charge your laptop quickly enough that it doesn’t drain. Some energy is lost in this changeover, as well as generally from heat. 20 percent efficiency loss is a general rule for normal charging, but around 30 percent (or even higher) is more realistic when fast charging.
Advertisement
With all these values, you can finally estimate how much additional time a power bank will run your laptop for. Say you connect a 20,000 mAh 45W USB-C bank to the theoretical laptop mentioned above. Subtracting 30 percent for the overhead, that 74Wh power bank has an effective capacity of ~52Wh. With a laptop averaging 14W, the power bank would extend its runtime by around 3.7 hours. If the laptop ever needs to draw more than the 45W the bank can provide, it will draw power from its internal battery alongside it — the bank is thus supplementing the internal battery to extend its life.
The important point is that you can’t assume a power bank’s capacity is the same as its output. A portable 50,000 mAh battery is great, but that capacity doesn’t tell you how much power it pushes. A large-capacity bank rated at 15W will only slow the laptop’s power drain, or it could be rejected entirely. For laptop banks, the label to look for is “USB-C PD.” In simple language, this means the bank and laptop negotiate a higher charging level than an ordinary USB port.
Always check the bank’s per-port output too, because the total output number can be deceptive. For instance, if the bank description says “100W total,” it may not be capable of this full output on any given port, or it may deliver less than 100W when you’re charging a phone and a laptop at the same time.
For most people, a 20,000 mAh/74Wh bank is a reasonable emergency or partial-charge option, while a 27,000 mAh/100Wh is closer to the sweet spot. In the US, 100Wh is also the limit for power banks allowed on a plane without approval. if you need suggestions, our favorite laptop power banks span all needs.

Why can’t my power bank charge my laptop?

Similarly to plugging your laptop into your car’s USB port, a weak power bank might be providing power to your laptop, but not as fast as the laptop’s battery is draining under use. There are a few other possibilities. Check whether your laptop supports charging through USB-C. Some USB-C ports handle data, video or other accessories, but can’t run a charger. If there’s no indication on the ports themselves, check the manual if you still have it or look at the product specs online.
Next, check whether the bank supports USB-C Power Delivery at a high enough per-port wattage. A basic 15W USB-C output can charge a phone, but won’t make a dent in a laptop drawing 65W+. If the bank’s output is below the laptop’s needs, the computer will either reject it or only charge under light use after warning you of a “slow charge.”
Lastly, check the cable, as not every USB-C cable is rated to carry high-wattage power. A standard USB-C cable generally supports up to 3 amps, while higher-power 100W and Extended Power Range connections will require a 5-amp-rated cable. USB PD 3.1 can provide up to 240W, but only when the laptop, bank and cable all support the needed power level.

As long as the hardware is compliant, your USB-C PD devices will negotiate a compatible voltage and current. Avoid anything that’s damaged or ancient cables you hauled out of a cardboard box — those aren’t going to handle today’s power needs.
