Battery Charging (USB-C )
The battery powers the starter motor and control module. This portable generator is equipped with
an automatic battery charging circuit. The battery will receive charging voltage only when the engine
is running. The battery will maintain a proper charge if the portable generator is used on a regular
basis (about once every two weeks). If it is used less frequently, the battery should be connected
to a trickle charger (not included) or battery maintainer (not included) to keep the battery properly
charged. If the battery is not able to start the engine, the battery must be connected to a type-C
style battery charger for re-charging before it can be used.
USB-C charging input supports 5V3A input 15W maximum.
