An Einhell energy unit is the emergency power pack for on the move. Even though jumper cables are already standard in car accessories, they only ever help when there is a second car to provide the power. If you want to play it safe or simply be independent of other power sources, it would be a good idea to get an energy unit or a jump starter from Einhell. These portable and extremely robust rescuers in times of need help to "revive" your car or motorcycle battery.
