Compact Power Bank

The Anker A1638 Nano Power Bank is a portable 10000mAh charger built for daily carry and travel. Its integrated retractable cable eliminates loose wires while the smart display shows real-time power flow. Designed for smartphones and tablets, it fits airline carry-on limits and suits users who want cable-free convenience.

Retractable Cable & 45W Output

A 2.3 ft built-in USB-C cable extends and retracts smoothly, rated for over 20000 bends to resist wear. The single port delivers up to 45W max output, charging an iPhone 16 Pro to 50% in 27 minutes, while 30W input refills the power bank in 2 hours. Pass-through technology lets you charge devices while the bank itself recharges.

Simple Use With Limits

Pull the cable, plug in, and the bank begins charging automatically with no buttons required. Usable capacity lands between 5500mAh and 6500mAh due to conversion loss, so laptop charging is not recommended. Multi-port use drops output to 15W per port with two devices or 7.5W each with three, and sustained 45W output is limited by heat.

Questions about this item

How much usable capacity does the 10,000mAh rating deliver to my phone?

Due to energy loss in the cells and circuit conversion, a fully charged unit provides about 5,500mAh to 6,500mAh of usable power for your devices.

What charging standard does the USB-C cable and port support?

The USB-C cable and port are compatible with Samsung Fast Charging 2.0 for supported devices.

What are the physical dimensions and mounting requirements?

The power bank is 16% smaller than standard models and features a built-in 2.3 ft retractable cable rated for over 20,000 bends, so no separate cable or mounting hardware is needed.
