Is the Anker Nano 45W power bank worth it?

At $34.99 at eBay as of November 4, 2026, it is a reasonable buy if you want a compact 45W pack with a built-in cable. You pay a small premium over plain 10,000mAh packs for the retractable cable.

Can it charge a laptop?

It can slow-charge small laptops and tablets over USB-C at up to 45W, but 10,000mAh will not fully refill most laptops. Treat it as an emergency top-up, not a full laptop battery.

How many times can it charge a phone?

Expect roughly two full charges for a typical phone, less if you charge at high wattage or use the pack in cold conditions.

Does it come in different colors?
