My favorite table for getting work done at my local coffee shop has no nearby outlet. To keep working after my computer hits 10 percent, I use a laptop power bank. Luckily, after a couple years testing batteries for Engadget, I have a good backstock to choose from. These high-capacity batteries are also excellent for travel, with the ability to recharge a phone, tablet and smartwatch— sometimes all at the same time (but, if you can help it, I find charging gadgets one at a time gets the best results). If you’re travelling or like to work away from your desk on occasion, this guide will help you pick the best laptop power bank for your needs based on our testing. We also include info on what different battery terms mean, note the latest info on flying with your bank and answer a few battery-related questions.
Editor’s note (6/16/25): Anker recently issued a recall on its PowerCore 10000 power bank (model A1263) due to fire risk. The recall pertains to units sold in the US through Amazon, Newegg and eBay between June 2016 and December 2022. If you have one of these batteries, you can contact Anker for a replacement or equivalent gift card. None of the batteries we currently recommend in this guide are part of the recall, and we haven’t recommended that model in previous iterations.

Best laptop power banks for 2025
Photo by Amy Skorheim / Engadget Best laptop power bank for travel Lion Energy Eclipse Mag Capacity: 27,000 mAh, 99.9 Wh | Ports: One USB-C in/out, two USB-A out and three wireless pads | Cable included: USB-C to USB-C and wall adapter | Charge time iPhone 15: 5 to 100% in 2h 56m (wireless) 5 - 100% 2h 22m (wired) | Remaining charge after iPhone: ~ 81% | Charge time Galaxy S23 Ultra: 5 to 100% in 1h 20m | Remaining charge after S23 Ultra: ~ 77% | Charge time iPad Air: 5 to 100% in 1h 55m | Remaining charge after iPad: ~ 64% | Charge time MacBook Pro: 10% to 89% in 1h 18m Traveling is one of the top reasons people need to use a portable laptop charger — planes, trains, buses and airports aren’t exactly the easiest places to find a power source. Lion Energy’s Eclipse Mag battery pack has a big 27,000 capacity, which is enough to power a laptop through a couple days of use. I also like how its three wireless charging pads cut down on cable chaos, letting you charge a Qi-enabled phone, earbuds case and Apple Watch at the same time. You certainly could charge all three of those accessories and a laptop at one time, but as with all batteries, that increased drain will quickly empty it and your charge times will slow down quite a bit. From what I’ve seen, the unit works best as an as-needed power supply when you’re out and about, then, after a recharge, it can moonlight as a three-in-one wireless charger in your hotel room. You can even rely on the pass-through charging capabilities to power up the battery while using the wireless pads, making it a sort of travel-ready multi-device charger. At two pounds, no one would call this light, but the angled corners and narrow design make it feel more compact than other big batteries. There’s no display to tell you how much charge is left, just four lighted pips at one edge, but I found them to provide a fairly accurate estimate. One thing to note is that the wireless watch pad only works with Apple Watches. Since Pixel watches don’t support wireless charging and Samsung only recommends its own chargers for Galaxy Watches, that's not surprising. The only other drawback is the single USB-C port. The three wireless pads and the two USB-A ports will likely be enough for a days’ work, but one more type-C port would be ideal. Compared to other 27,000 maAh battery packs, the $174 price tag on the Eclipse Mag is a decent deal — and it even comes with a five-year warranty. Pros Wireless charging is convenient for travel
