With a new design, this product is available in a reduced size and weight of just 19.8 pounds. It is easily wall mounted or transportable to provide on the spot service to a disabled vehicle. Once set, the device does not need the presence or assistance of an operator. As a charger, it can replace a battery charger temporarily under repair. As a current generator, it can recover totally discharged or sulphated battery packs by providing constant current. This allows for de-sulphation to regenerate batteries normally considered no longer usable.
