ANKER Laptop Power Bank, 25,000mAh Portable Charger with Triple 100W USB-C Ports for Multi-Device Charging, Built-in and Retractable Cables, for iPhone 16/15 Series, MacBook, Samsung, and MoreClimatePartner certified

The media could not be loaded. I’ve had the ANKER Laptop Power Bank (25,000mAh with Triple 100W USB-C Ports) for a few days now, and I can say with complete confidence: this is by far the best power bank I’ve ever used in my entire life. I’ve gone through a number of portable chargers over the years—some decent, some disappointing—but this one completely blows everything else out of the water.First off, let’s talk about power. This thing packs a serious punch. With 25,000mAh of capacity, it’s more than just a phone charger—it’s a full-on mobile power station. I’ve been using it mainly to charge my 17-inch MacBook Pro, MacBook Air M1, and a couple of iPhones, and it handles everything at the same time with zero hesitation. I also occasionally plug in my iPad Pro, my Sony over-ear headphones, and even a GoPro when I’m on the go. This power bank doesn’t flinch. It keeps everything powered and charged without breaking a sweat.The fact that it has three 100W USB-C ports is game-changing. You don’t have to prioritize what needs charging first—you can just plug everything in and let it go. I regularly have two laptops and a phone connected simultaneously. I’ve never had another power bank that could manage this much draw at once without either throttling performance or getting uncomfortably hot. This one stays impressively cool and consistent, even under heavy use.Charging speed is fast—really fast. I’ve gotten used to bringing a charger and waiting around for a few hours to top off my MacBook Pro, but with this Anker, I can get it from nearly empty to over 70% in just about an hour, sometimes less depending on background use. Same goes for my iPhone and MacBook Air. There’s no noticeable lag in charging speed even when multiple devices are plugged in.The build quality is solid. It’s got a sturdy, premium feel without being bulky or overly heavy. It’s not the lightest power bank I’ve ever used, but considering the capacity and output, it’s surprisingly compact for what it delivers. I toss it in my backpack or laptop bag every day, and it fits comfortably next to my gear. It definitely feels like a professional-grade device, not some gimmicky charger dressed up to look impressive.Another huge plus: the digital display. It gives you an accurate, real-time readout of the remaining battery percentage, as well as input/output wattage. That may sound like a minor feature, but it’s incredibly helpful when you’re juggling multiple devices. I can easily see how much juice I’ve got left and how fast each device is charging. No guesswork, no surprises.From a day-to-day usability standpoint, it’s been incredibly reliable. I’ve used it while commuting, working at coffee shops, and even on a short trip, where it kept my devices powered through several long days without ever needing a wall outlet. It charges itself quickly too—if you’ve got a proper high-wattage USB-C wall charger (I use Anker’s 100W Nano II), you can get the whole thing recharged in under two hours, which is amazing for a battery this size.To sum it up: this is not just a power bank for topping off your phone. It’s a true multi-device, high-output powerhouse. Whether you’re a remote worker, a student, a photographer, a traveler, or just someone who needs reliable power on the go, I can’t recommend this enough. It’s the kind of product that instantly makes you wonder how you ever got by without it.Anker absolutely nailed it with this one. It’s a bit of an investment compared to smaller chargers, but the performance, versatility, and build quality more than justify the price. If you’re even thinking about getting a laptop-capable power bank, stop thinking and just get this one. You won’t regret it.

I was about to return it. It seemed like it didn't last as long as it should when plugged into my laptop. I decided to get scientific about it and record stats, then let the ChatGPT do the calculation grunt work. Bottom line - this battery pack is in line with the stated specifications. I like the built-in cords too.-- My observations (prompt for ChatGPT) --I have an laptop with a 80wh battery which is discharged to 2%I have a 90wh external battery that I am using to recharge itAt 1:06, the external battery is reporting 100%At 1:23, 80%at 1:48, 49%at 2:19, 5%[I used a separate PD 3.1 240w rated cord to plug the power bank into the laptop - not the built-in cords. This in bracket was not part of the prompt]--- ChatGPT response beginLet's break down what happened:The Setup:• Your laptop battery is rated at 80 Wh and was nearly empty (around 2%).• You used a 90 Wh external battery to charge the laptop.The Reported Readings:• At 1:06, the external battery showed 100% (full capacity, which is 90 Wh).• At 1:23, it dropped to 80%—a 20% reduction, which translates roughly to 18 Wh (20% of 90 Wh).• At 1:48, it read 49%—a further drop of 31% or about 28 Wh (31% of 90 Wh).• By 2:19, it was down to 5%—a drop of 44%, approximately 40 Wh (44% of 90 Wh).Energy Delivered:Adding those drops together:• 18 Wh + 28 Wh + 40 Wh ≈ 86 WhThis total is close to the rated 90 Wh of the external battery. It suggests that nearly the full capacity was used, with any small discrepancies likely due to rounding, measurement uncertainty, and minor conversion inefficiencies.Considering the Laptop Battery:An 80 Wh battery starting from about 2% will need roughly 78–80 Wh to reach full charge, assuming 100% efficiency. In practice, charging systems have losses (typically around 5–10%), so the energy drawn from the external battery might be a bit higher than what actually gets stored in the laptop battery. In your case, the external battery delivered around 86 Wh, which is reasonable when you account for these losses.Conclusion:The external battery’s behavior—discharging nearly its full 90 Wh capacity over the course of the charging session—is consistent with its rating. In other words, given the slight inefficiencies inherent in voltage conversion and charging circuitry, the numbers you observed are within the expected range. This means the battery is performing as rated.So yes, based on the energy calculations and typical system losses, your external battery appears to be performing in line with its 90 Wh rating.--- ChatGPT response end

During a recent 3-day power outage, my 7 year old Anker 25K mAh power bank kept our phones and ipads alive - if we were careful with their use. On the second day I started thinking it would have been nice to have a second one, just in case, and I had been eyeing these on Amazon for some time. Most of our devices are USB-C now so the 2 built in connectors wiil just plug in, and a 4-pack of Thunderbird adapters is cheap enough to just put one in each travel bag - in case we forget to take one of the many USB-A/Thunderbird cables we already have.So I bought this one as soon as we could get back online. This is a VERY nice upgrade of the older model. It seems to recharge a lot faster, and clearly charges the Apple M1 tablet and computer MUCH better than the old one which was basically made for phones of the day. So while the capacity may be the same as before (thanks TSA) the functionality is much greater for today's technology. The built in cables are convenient, and the various readouts are comforting if not absolutely necessary. But as I can't seem to stop getting older, I'm finding that comfort, in the form of additional information like this device provides, is worth paying for.It's a bit heavier than the older model, but probably about the same size if you measure volume. Its square shape will make it harder to fit into my carry-on computer bag than the older, flatter model, but I wouldn't give up its improvements for the flatter shape. I'll find a computer bag that works better if it comes to that.Overall, I'm very pleased with the product. If it lasts and performs as reliably as the older one it will be a more than worthwhile purchase.
