Anker Nano Power Bank 10000mAh 45W Retractable Cable A1638

Go-To Power Solution

The Anker Nano Power Bank A1638 packs 10,000mAh capacity and 45W max output into a body 16% smaller than standard models. A built-in 2.3 ft retractable USB-C cable withstands over 20,000 bends for tangle-free charging. The smart display shows real-time status while 24/7 battery protection ensures safe operation. It suits travellers and commuters needing reliable portable power for phones and tablets.

Replaces Bulky Chargers

This unit replaces separate power banks and cables with a single flight-approved device supporting pass-through charging. The jump is worth it when you need 30W max input to replenish the bank in 2 hours and 45W single-port output to charge an iPhone 16 Pro to 50% in 27 minutes. Usable capacity lands between 5,500mAh and 6,500mAh after conversion losses, so it is not for users expecting the full rated capacity or sustained laptop charging.

Pull, Adjust, and Charge

Installation is simply pulling the retractable cable and connecting your device; no extra cords are required. The cable retracts back into the housing for neat storage. What usually goes wrong: output drops to 15W max per port with two devices and 7.5W with three, and charging speed may slow as devices heat up. The supplier advises against laptop use due to limited capacity and heat buildup during high-power output.
