This is the backup battery that simultaneously supplies power to four electronic devices with a Qi wireless charging top, two USB ports, and one USB-C port. Slightly larger than a smartphone, it stores unobtrusively in a carry-on bag or backpack and its 6,000 mAh battery charges without the nuisance of cord via a foldable AC adapter. Its USB-C port provides fast charging up to 18W and its wireless charging supplies power to any Qi wireless enabled devices including iPhone 8 and up, Samsung Galaxy 7 and up, as well as various LG and Pixel models. When plugged into AC, the battery supplies power to connected items before recharging itself. 7" L x 4 1/4" W x 1 1/2" D. (9 oz.)
