Best power bank for laptop charging

Updated 2026-11-06

Short answer. The best power bank for laptop charging is the UGREEN 145W 25000mAh 3-Port Power Bank ($79.99; buy: https://dealectric.com/go/ugreen-145w-25000mah-3-port-power-bank): 140 W from one USB-C port, 25,000 mAh (90 Wh), 18.1 oz, and a 65 W recharge that refills it in about 2 hours. Yes, a power bank can charge a laptop, but only through a USB-C Power Delivery port, and capacity is the real limit: 90 Wh is about one full charge for a 13- or 14-inch laptop and roughly 70% of a 16-inch MacBook Pro, while staying under the 100 Wh airline carry-on limit. Reviewers at Engadget, Dexerto and Camera Jabber ran MacBooks from it for weeks; Camera Jabber took a 14-inch MacBook Pro to 50% in about 30 minutes.

Two Amazon-only banks beat it in narrow cases. The Anker Prime Power Bank (26K, 300W) is the honest winner if you charge two laptops at once or hate waiting: two 140 W ports, 99.75 Wh, and it refills to 80% in 40 minutes, at $229.99 on anker.com (seen 2026-11-06). Engadget's overall pick, the Anker Laptop Power Bank (25K, 165W), wins on built-in cables, but its laptop port tops out at 100 W and it costs $119.99 on anker.com. Our brand's answer to it is the Baseus EnerFill FC41 25,000 mAh 145 W ($79.99; buy: https://dealectric.com/go/baseus-enerfill-fc41-25000mah-145w, code FC41 saves $33, pre-applied by the link): two built-in USB-C cables, 140 W on one of them, 91.25 Wh and 18.2 oz, at the same price as the UGREEN. If your laptop only charges from a barrel plug, no USB-C bank will help; you need an AC outlet like the Goal Zero Sherpa 100AC ($249.95 on Amazon (checked 2026-11-12); buy on Amazon: https://www.amazon.com/dp/B0BFBTR94M?tag=dealectric-20).

Before you buy, read the output line on your laptop's charger. Watts equals volts times amps: a 20 V, 3.25 A brick is 65 W, and a bank with a 100 W port covers it. A 20 W phone bank will not charge most laptops, and a 45 W bank will charge an ultrabook only slowly. Gaming laptops that ship with a 200 W or 240 W barrel adapter will run from a 100 W USB-C bank only at idle.

What owners complain about

The laptop will not charge, or charges at a crawl. This is the top complaint by far. A Reddit user's 45 W Samsung bank fed a laptop only 15 W because the two sides could not agree on a Power Delivery profile. HP forum posts describe banks that work for ten minutes and then cut in and out on a ZBook. Cheap cables without an e-marker chip cap a 140 W port at 60 W or trigger a charging-paused error. The fix is the same every time: a bank with a 100 W or 140 W PD port, a 5 A-rated cable, and a laptop that accepts USB-C charging at all.

Output falls as the bank empties. Dexerto measured the UGREEN's laptop port dropping to about 65 W near 25% charge. Engadget saw a 16-inch MacBook Pro peak at about 90 W on the Anker 25K even though the port is rated 100 W.

Weight. Every 25K laptop bank weighs 18 to 21 oz, and the Sherpa 100AC is 2.1 lb. Buyers of the Anker 25K call weight its only issue.

Slow self-recharge. The UGREEN and Baseus take about 2 hours on a 65 W charger. The Anker Prime 26K takes 250 W and is back to 80% in 40 minutes.

Units that die after months. Several 100 W Baseus and no-name buyers on eBay and marketplace listings report a bank that shows full but stops delivering power; one UGREEN 145W buyer reported it draining from 70% to empty overnight while plugged in. These are scattered single reports, not a pattern, but keep the receipt.

Screen scuffs. Engadget notes the Anker 25K's glossy display dulls with use.

Which one by need

Not recommended

20 W to 45 W phone banks for any laptop over 45 W. They either refuse to charge it or add a few percent per hour.

Anything over 100 Wh for air travel. UGREEN's 48,000 mAh 300 W unit is 153.6 Wh and needs airline approval, which several carriers no longer give.

A USB-C bank for a 200 W gaming laptop. It will hold the battery at idle but not under load. Use the AC-outlet route instead.

AOHi The Black Warrior 25,200 mAh 170 W. Same price as the UGREEN but 23 oz with no independent hands-on review we could find.
