Our take on the Anker 20000mah 15w power bank

A high-capacity Anker power bank with a 20,000mAh battery and a built-in display that shows remaining charge. It tops out at 15W, so it charges phones at a steady but not fast pace and is aimed at people who need several full phone charges away from an outlet. Compared with higher-wattage Anker models, it trades speed for capacity and a clear battery readout. Owners value the large reserve and the display; those wanting quick top-ups from modern phones will find 15W limiting.

What reviewers say

Owners generally rate this Anker bank highly for its large reserve and the display that removes guesswork about remaining charge. The common complaint is speed: 15W feels slow next to fast-charging rivals, and refilling the bank itself takes a long time.

Questions and answers

How many times can it charge a phone?
With 20,000mAh, expect roughly four to five full charges for a typical phone, less for large phones or heavy use.
Does it support fast charging?
It tops out at 15W, so it does not fast-charge modern phones that support higher USB-C Power Delivery speeds. It charges steadily rather than quickly.
How long does it take to recharge?
Recharging the full 20,000mAh takes several hours, so plan to leave it plugged in overnight.
What can I charge with it?
Phones, earbuds, smartwatches and other small USB devices. It is not suited to laptops, which need higher output.
Is it allowed on a plane?
Yes. At 20,000mAh it is under the common 100Wh carry-on limit, but keep it in your cabin bag, not checked luggage.
What is in the box?
The power bank and a charging cable. A wall adapter for recharging it is not included.
Where is the Anker 20000mah 15w power bank cheapest?
At Best Buy, for $49.99, as of our latest check.
