The Anker Nano Power Bank A1638 combines a 10,000mAh battery, up to 45W USB-C output and a built-in retractable USB-C cable in a compact portable charger. It is designed for buyers who want one power bank for phones, tablets, earbuds and compatible USB-C laptops without carrying a separate short cable.
Manufacturer-listed model: A1638. This page is for the Anker Nano Power Bank (10K, 45W, Built-In Retractable USB-C Cable), not a Baseus product.

What 45W means in practice
The 45W rating is the maximum available from the USB-C port or built-in USB-C cable when that output is used on its own with a compatible device. Charging more than one device divides the available output. Anker lists a maximum combined output of 22.5W when the USB-C port and built-in cable are used together, and 22.5W total when all three outputs are active.
Actual charging speed depends on the connected device, its charging protocol, cable or adapter requirements, temperature and battery state. A device that accepts only 20W will not charge at 45W just because the power bank can supply it.
Who should shortlist the A1638?
- USB-C phone users: the retractable cable reduces the need to carry a separate cable for current Android phones and USB-C iPhones.
- Samsung users: the USB-C outputs list PPS support, but the exact device still controls the negotiated speed.
- Students and commuters: 10,000mAh is a practical balance between daily backup and bag weight.
- Light laptop users: 45W can support compatible USB-C laptops, though it is below the requirement of many performance laptops.
- Multi-device buyers: USB-C, USB-A and the integrated cable cover common phone and accessory combinations.
Important buying notes
- The 10,000mAh cell rating is not the same as 10,000mAh delivered at the phone battery after voltage conversion and charging losses.
- Maximum output falls when multiple devices charge together.
- For faster recharging, Anker recommends a compatible 30W or higher USB-C Power Delivery adapter.
- Older Lightning iPhones require an appropriate USB-C-to-Lightning cable or adapter; the built-in connector is USB-C.
- Check the current product variant, box contents, stock and warranty terms before ordering.

Yes. Anker lists a retractable USB-C cable approximately 70cm long.
Can the A1638 charge a laptop?
It can charge compatible USB-C laptops that accept its available USB-C Power Delivery output. Many larger or performance laptops need more than 45W, so confirm the laptop's input requirement.
