Editorial picks, compared and dated.
By Diego SalasDiego Salas · Charging & Power Banks EditorPublished in September 2026A power bank is only useful if it matches what you actually carry. A 10,000mAh pocket pack will top up a phone twice; a 25,000mAh unit with 140W output will run a laptop through a transatlantic flight. We compared five Anker models across the range on real capacity, output wattage, port count and weight, so you can pick by device rather than by marketing numbers.

Buyer's Guide
Match the capacity to your devices
10,000mAh is enough for one to two phone charges and stays pocketable. 20,000mAh covers a phone plus a tablet or a long day out. 24,000-25,000mAh is the point where laptop charging becomes realistic.
Wattage decides what you can charge
Output is what separates these models. Anything under 30W will trickle-charge a laptop at best; 65W charges most ultrabooks; 140W is for larger laptops and fast phone charging at the same time.
Ports and pass-through
Two USB-C ports plus USB-A covers almost everything. Check whether the bank supports pass-through charging so it can charge itself and a device from one wall socket.
Airline rules
Most airlines cap lithium batteries at 100Wh, which is roughly 27,000mAh. Every model here is under that, but the 25,000mAh unit is close enough that you should check your airline before packing it.
Weight is the hidden cost
Capacity and weight rise together. If you carry the bank daily, the 10,000mAh models are the ones you will actually keep in a bag.
FAQ
Yes, the 24,000mAh 140W model and the 25,000mAh unit are the two built for it. The 10,000mAh models are phone-first.
Roughly two charges from 10,000mAh, four from 20,000mAh and five or more from the 24,000-25,000mAh models.
Yes. All are below the common 100Wh limit, but power banks must travel in the cabin, not in checked bags.
The compact 30W 10,000mAh model - it is the lightest way to guarantee a full phone charge.
Some are. If you buy through them we may earn a commission, and it never changes a ranking.
