To charge the NOCO Boost Max GB251plus, follow these steps:
1. Connect the GB251 to a power source using the included 12V DC car charger or XGC4 wall charger. The 12V IN port is used for charging.
2. The GB251 comes partially charged, but it is recommended to fully charge it before use.
3. The charge level of the internal battery is indicated by the Charge LEDs. The LEDs will slowly pulse on and off and become solid until all four Charge LEDs are on.
4. When the battery is fully charged, the Green 100% LED will be solid, and the 25%, 50%, and 75% Charge LEDs will turn off.
5. From time to time, the Green 100% LED will pulse, indicating maintenance charging is occurring.
Note: Do not use generic or third-party power adapters, as they may present a serious electrical risk. Only use the provided chargers.
