Frequently asked questions

Which vehicles can this jump starter start?

Vehicles with a 12 V battery: cars, vans, motorcycles with a 12 V battery, boats and light machinery.

How do I jump-start a vehicle with a jump starter?

With the ignition off, connect the red clamp to the battery positive (+) and the black one to the negative (−) or to a metal part of the engine. Switch the jump starter on if it has a switch and crank for 5 seconds at most; if it does not start, wait a minute before trying again. Then remove the black clamp first and the red one last.

How often should it be recharged?

After every use and, if it is stored, roughly every three months. This keeps its internal battery healthy and ready when you need it.
