Our take on the Mophie Prime 20 Portable Power Bank 20,000 mAh 18W

The Mophie Prime 20 is a 20,000 mAh portable power bank with two USB-A ports and one USB-C port, so it can charge three devices at once. The USB-C port supports 18W Power Delivery, enough for fast charging on phones and tablets, and it doubles as the input for recharging the bank. Its case is made with up to 50% post-consumer recycled plastic, and a 1 m USB-C to USB-C 60W cable is included. It suits commuters, travelers and anyone who needs multi-day backup power, though at 20,000 mAh it is heavier than pocket-size 10,000 mAh banks.
