Jump starter for 12V gasoline engines with up to 8 liters of displacement and diesel engines with up to 6 liters of displacement. The 4-in-1 multifunction device features a built-in compressor to inflate your car tires: simply attach the appropriate valve adapter to the air hose and set the desired air pressure. The electric pump automatically shuts off once the set tire pressure is reached. The integrated LED lamp with 300 lumens and 3 modes (SOS, strobe, and continuous light) serves as a durable flashlight. You can also use the device as a power bank to charge smaller mobile devices such as smartphones, digital cameras, or tablets via the USB Type-A charging port.
