Charging by a car
Connect one end of the car charger to the cigarette lighter port, connect the other end to the 7909 input
port (14), the charging indicators (3) and (4) will turn green.
Failure to comply with the following recommendations may damage the battery.
1. Charge the battery before storage and charge it fully at least 6 months. Store the unit in a cool
and dry place.
2. If the main power supply shuts down automatically due to lower battery capacity, recharge the
battery within 3 months. Otherwise, the battery capacity will not be restored.
Low temperatures (below zero) can affect the capacity of the power station battery. If kept in sub-zero
conditions, the battery may be discharged. Never charge the unit in sub-zero conditions as this will
damage the battery and its capacity may not be recovered.
