Review the exact model, included items, seller and current price before ordering.
The GENIUS1 is a 1-amp charger and maintainer for supported 6V and 12V batteries. Supported chemistry and voltage depend on the selected mode and the manufacturer’s instructions.
Identify battery chemistry, voltage and capacity before selecting the charging mode. This is not a Milwaukee or RYOBI tool-pack charger and not a jump starter.
You need engine starting assistance or faster charging than a 1-amp unit can provide.
Start with the work you need to do and the equipment you already own. Compare the complete setup cost, including any required accessories, consumables or power source.
Keep the battery-maintenance setup distinct from the cordless-tool charging station. Follow the battery and charger instructions for connections, location and operating conditions.
