FAQ’s

Q1: Which power stations work with Charger 2? Can it charge third-party power stations?

A: Charger 2 works with all BLUETTI power stations and most third-party stations that use MC4 connectors for solar charging. However, some third-party stations may have unstable charging rates.

Q2: Charger 2 can draw up to 800 W from the alternator and up to 600 W from solar. What’s the charging strategy for consistent 1,200W power?

A: The total charging power is limited to 1,200 W. Solar input always takes priority, and the rest is supplied by the vehicle starter battery and, if necessary, the BLUETTI auxiliary parking battery.
Here’s how it works:
⚪ If solar provides 600 W, the starter battery supplies 600W.
⚪ If solar provides 400 W, the starter battery supplies 800 W.
⚪ If solar provides 200 W, the starter battery supplies 800 W, and the remaining 200 W comes from the auxiliary parking battery to complete the 1,200 W charge

Q3: Do I need to adjust Charger 2 for different power stations?

A: Yes, after you activate Charger 2, adjust the charging voltage using the BLUETTI app to match your power station’s specs.
