The Peak Power Pack is a full replacement for heavy lead-acid batteries where high currents flow for short periods. Developed primarily for RV users, it is equipped with a built-in charger that allows it to be charged using the vehicle's electrical system while on the road. This way, the pack is fully charged by the time it reaches the campsite. If necessary, charging can also be done with an adapter from a wall socket. It can also be charged with solar power.
