Product Information

Another vehicle with a fully-charged battery (avoid a hybrid or electric car as this could cause damage). Differing lithium technologies, such as Lithium Polymer or Lithium Carbonate, have their own requirements, with some needing nothing more than a six monthly top up. It might be something simple like an interior light left on, but if not, it could be time to replace the battery. A cable with at least an eight gauge will be fine for most cars, though larger batteries might need a 6- or 4-gauge cable. If your car won't start at home, it could be because of a flat battery, failed starter motor or a faulty alternator – all things we can help with.

Power Station

Having a set of jumpstart cables in your motorhome can save you a lot of waiting around after a soggy camping holiday in Scarborough. It won't be able to jump-start your car dozens of times before it needs to be recharged, but if all goes well, you should need it only to get the car going just this one time, right? While compact packs can normally be stashed somewhere under the bonnet during starting attempts, longer leads obviously allow more positioning flexibility. Every Powervamp automotive jump starter is fitted with an audible reverse polarity warning system as well as a voltage spike suppression PCB to protect the vehicles own ECU, as standard.A booster is only as good as its internal charge, but it’s easy to forget to regularly top up the unit if it’s not being used. In other words, it might be the way to go in a pinch, but if you can avoid jump-starting your car, it’s probably best to do so. Then attach the other end to an earthing point (unpainted metal on the engine block or chassis) well away from the flat battery and fuel system.
