A slim 4000 mAh power bank with a built-in lithium-ion battery, UL listed and CE, FCC and RoHS certified. It charges over micro-USB at 5V/1A and comes with a micro-USB cable in a white tuck box. The capacity is small by current standards: it covers roughly one phone top-up, not a weekend away. It suits a light, occasional backup rather than heavy users, who will want a larger battery and faster USB-C charging.
