I bought this device today tired of dealing with jumper cables. Always need another car to jump start with.
The 451 battery is located under the passengers foot well. To jump start. You have to have the door open really
Wide. Pull a car up to the opening.
This unit, can jump start, up to 20 cars with one unit charge. Its charges, up by USB. It has a flash light, to external USB ports. For charging you phone, and pads. Nice if your out in the middle of nowhere, with a dead battery. No other resources there to assist you.
What everyone else using
