Our take on the Anker A1638H21 Nano Power Bank 10K, 45W

The Anker Nano Power Bank 10K is a compact 10,000mAh battery with up to 45W USB-C output and a built-in retractable USB-C cable. The 45W output is enough to fast-charge most phones and many tablets, and the integrated cable means you can leave your own cable at home. It suits commuters, travelers and anyone who wants a small backup battery without carrying extra cables. Against rivals, it trades a second port and a display for the convenience of the built-in cable and a smaller footprint.
