The Einhell cordless compressor Pressito 18/21 never runs out of air. It has a variety of uses, from inflating to deflating. This compressor is a member of the Power X-Change family: The PXC battery can be used in all devices from the system family. Thanks to its high-pressure pump, the compressor can be used to inflate car tires, cycle tires and balls; its low-pressure pump on the other hand can be used to inflate air mattresses (and later on to deflate them in low-pressure suction mode). The compressor is equipped with a digital pressure indicator designed for easy manual operation; you can choose between the units Bar, PSI and kPa. The pressure you require can be set on the high-pressure pump. Other practical features include an auto shutoff function upon reaching the selected pressure and a push button for inflation in the high-pressure range without pressure pre-set. This cordless compressor comes with a storage compartment for the 3-piece adapter set. One 18 V battery is needed for operation. This product comes without a battery or charger. These are available separately, for example as a practical Einhell starter set.
