5. Operating Instructions
The UpBright 12V AC DC Adapter functions as a power supply for your EverStart Maxx MJ16CE unit. Its primary use is to charge the internal lithium battery of the jump starter or to power the unit directly from an AC outlet.
- Charging the EverStart Maxx MJ16CE:
- Ensure the adapter is correctly connected to both the EverStart Maxx MJ16CE unit and a live AC power outlet as described in the "Setup" section.
- The EverStart Maxx MJ16CE unit will begin charging its internal battery. Monitor the charging status on the jump starter's display or indicator lights.
- Once the EverStart Maxx MJ16CE unit is fully charged, disconnect the adapter from the wall outlet first, then from the jump starter.
- Powering the EverStart Maxx MJ16CE:
- If your EverStart Maxx MJ16CE unit can operate directly from an external power source without relying solely on its internal battery, connect the adapter as described in "Setup".
- The adapter will provide continuous 12V DC power to the unit.
Refer to the EverStart Maxx MJ16CE user manual for specific charging times and operational details of the jump starter unit itself.
