The SUNGZU SKA2500 is a portable power supply that resembles a bag. It has a capacity of 2,500Wh and a battery that supports a maximum output of 4,000W in a hand carrier. It resembles an aluminum bag, but it does not damage the internal battery even if it is struck by a 2 ton car to drop it from a height of 3 m.
The supply capacity is 1.8 hours for a 1,300W microwave oven, 15-20 hours for a 150W refrigerator, 2.9 hours for an 800W electric drill, and 3.4 hours for a 700W air conditioner. Electric vehicles like Tesla can also provide enough supplies to run 17-20 km.
