Our Take

Best for: Travelers and commuters who need a dependable extra charge for their phone.

This Anker 20,000mAh power bank delivers dependable backup power for a weekend away or a long day out. The two ports let you charge a phone and a pair of earbuds at the same time, and the 20,000mAh capacity covers multiple phone recharges before the bank itself needs a refill. Anker's build quality is solid, with a durable shell and basic safety protections built in. The main tradeoff is the 15W total output. That is slower than the 20W or 30W chargers Anker now sells, so do not expect fast charging on a modern phone or any hope of topping up a laptop. The USB-A port is handy for older cables, and the USB-C port is the better choice for newer devices. 99, this is a practical, no-frills power bank for anyone who just wants reliable extra battery life without paying for features they will not use.

Price Analysis

At $26.99, this is 46% below the original $49.99 price. That is a solid discount for a 20,000mAh Anker power bank. Given the price, now is a good time to buy if you need a dependable backup battery.

Common Questions

How many times can it charge my phone?

A 20,000mAh power bank charges a typical smartphone about four to five times, depending on the phone's battery size and how much it is used while charging.

Can I charge my phone and tablet at the same time?

Yes, the dual ports allow charging two devices at once. Keep in mind the total output is 15W, so both devices will charge more slowly than with a single-port fast charger.

How long does it take to recharge the power bank?

With a standard 15W USB-C charger, recharging the 20,000mAh battery takes roughly six to seven hours. Using a lower-power charger will take longer.
