  • 45W maximum output charges iPhone 16 Pro to 50% in 27 minutes

Go-To Power Solution

The Anker Nano Power Bank A1638 delivers 10,000mAh capacity with 45W maximum output through a built-in retractable USB-C cable. A smart display shows real-time status while pass-through technology and 24/7 battery protection keep charging safe and efficient for daily use.

Suits phone and tablet owners wanting one cable

Travellers and commuters who prefer an integrated 2.3 ft cable will appreciate the compact, flight-approved design that is 16% smaller than standard models. Buyers needing laptop charging or sustained high-wattage output should look elsewhere because capacity and thermal limits restrict extended 45W delivery.

Pull-out cable simplifies setup

Extend the durable retractable cable rated for over 20,000 bends, connect to a USB-C device, and charging begins automatically. Replenish the power bank at up to 30W input for a full recharge in about 2 hours. Using multiple ports reduces single-port output to 15W with two ports or 7.5W per port with three.

Questions about this item

What USB-C device do I need to recharge the power bank at 30W?

Any USB-C charger that delivers up to 30W input will replenish the power bank to 100% in about 2 hours.

Will my older phone that only accepts 15W still charge from the single port?

Yes, the single USB-C port negotiates down to 15W automatically, so older phones charge normally.

How can I confirm the power bank is delivering 45W to my iPhone 16 Pro?

The smart display shows real-time output; expect around 50% charge in 27 minutes when the phone accepts full speed.
