5. Initial Setup and Charging
5.1 Charging the Internal Battery
Before first use, fully charge the unit's internal battery. The unit may arrive partially charged from the manufacturer. It is recommended to fully charge the device immediately after purchasing and before using it for the first time. Charging via AC current will take several hours. Always unplug the unit once the battery status indicator turns green to prevent overcharging.
- Using the AC Charging Adapter:

Connect the AC charging adapter to the unit's charging jack and then plug it into a standard wall outlet. The charging indicator will show the charging status. Unplug when fully charged.
- Using the DC Charging Adapter (12V):

Connect the DC charging adapter to the unit's charging jack and then plug it into your vehicle's 12V DC outlet. This allows for convenient charging while on the go. Unplug when fully charged.
- Using the Emergency Hand Generator:

In situations where no external power source is available, the integrated hand generator can be used to charge the internal battery. Pull the handle firmly and allow it to retract completely before pulling again. Do not exceed the maximum cord length of 30 inches. Check the battery indicator periodically while hand-cranking.
Caution: Do not overcharge the unit. Wait at least 1 hour after use before recharging.
