Got an accessory socket on your bike and want to connect a device with an SAE fitting like a MotoPressor Pocket Pump? This clever adaptor comes with a male lighter fitting that will fit BOTH car and motorcycle lighter sockets. To plug into a motorcycle style (Hella) socket, simply remove the RED adaptor at the front of the plug and plug straight into the motorcycle socket. To plug into a car socket, leave the RED adaptor in. Now you can use your MotoPressor Pocket Pump on both your bike and car.
