heli® Take. Charge. is the result of nearly a decade’s worth of field research in the harsh and unforgiving climates of the developing world. heli® systems are built around the needs of the user. You choose a power source – be it from the wall, the car, or the sun – and then store that power for later use in their heli® 2200 Lantern, heli® 4400 Lantern, or one of three heli® Bank power banks.
