Laptop power banks come in handy if you often travel or work away from your desk. These larger batteries have enough capacity to refill your computer to around 75 percent, giving you many more productive hours. Of course, they can also charge smaller devices like your phone, camera or tablet a few times over. Nearly all portable laptop chargers fall below the 100-watt-hour mark so you can bring them in your carry-on when you fly. Additional features, like built-in cables and digital displays make these battery banks easier to use, too. We tested over a dozen options and put our thoughts below, so you can find the best laptop power bank for your next trip away from an outlet.

Best laptop power banks for 2026
Amy Skorheim for Engadget Best laptop power overall Anker Laptop Power Bank 25K Capacity: 25,000mAh, 90 Wh | Ports: Two built-in USB-C in/out cables, one USB-A port, one USB-C port | Cable: USB-C to USB-C | Number of charges iPhone 15: 4 - 5 | Charge time iPhone: 5 to 100% in 1h 54m | Number of charges Galaxy S23 Ultra: 3.75 - 4 | Charge time S23 Ultra: 52m | Number of charges iPad Air: 1.75 - 2 | Charge time iPad: 5 to 100% in 1h 58m | Number of charges MacBook Pro: 0.68 | Charge time MacBook Pro: 53 m My favorite new feature for power banks is the built-in cable. This Anker laptop power bank sports two: one attached to the side of the battery that doubles as a carrying strap and another retractable cord that extends up to two feet. Both are USB-C and can accommodate in/out charges so you can use them to refill a device or reup the battery itself. The brick has a display to tell you the amount of charge remaining, as well as the output wattage that’s funneling towards your devices from each port. When refilling the battery, you can see an estimate of how long it will be until the unit is full. Calculating and displaying info like that takes up a bit of power but, in my testing, the battery output the same or a higher amount of charge compared with other 25,000 mAh packs. The 25,000 mAh capacity isn't as high as other TSA-compatible power banks, but sacrificing those few extra percentage points for this bank's speed, convenience and great price is definitely worth it.

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
