This optional kit charges the battery using a specialized connection cable and AC power adapter. Designed specifically for use with Vantage Connect (6620) and Heavy Duty Solar Power Kit (6612) to charge the 6-volt battery for installations with prolonged periods of low light and accessible power. The AC adapter has a universal input (100-240V, 50-60Hz) and will work anywhere in the world.
A wall-plug adapter may be necessary for use in some countries. Wall-plug adapters can be found online or in electronics or home stores.
