It includes 2 2.1A USB power outputs, 3 modes (normally bright, flash, SOS) work lights, Bluetooth speakers, wireless charging, phone hands-free, car emergency start, six very practical and necessary functions, and is the best companion for your outdoor car life! The overall "round edge" is novel and elegant in shape, strong and durable. The size of the whole machine is extremely compact, and the special "cage structure design" makes the overall structure compact and stable. Six compatible and coordinated electronic modules and 12000mAH lithium iron phosphate batteries are plugged in a space with a diameter of only 80mm and a height of 155mm, so as to be able to get stuck on the cup holder of ordinary cars, facilitate charging and discharging; several edges on the side can be placed on the plane smoothly without sliding and falling. The plastic boss at the back can be hooked on the backpack or other places of use, making it easy to travel and carry. The internal electronic components have been treated with special three-proof coating, and the overall IP grade can reach IP43, which is generally not hindered by light rain. The whole machine can also be charged wirelessly, making it more convenient to use!
