BLUETTI Charger 2 | 1200W Alternator & Solar Dual DC Charger
- Charge compatible BLUETTI power stations from a vehicle alternator, solar panels, or both, with up to 1,200W charging output.
- Designed for 12V and 24V vehicle electrical systems, including vans, motorhomes, RVs, trucks and suitable smart-alternator vehicles.
- Use app-based monitoring and reverse charging to help maintain or recover a compatible vehicle starter battery.
BLUETTI Charger 2 alternator and solar DC charging
The BLUETTI Charger 2 is a 1,200W DC-DC charger that combines available vehicle alternator power with solar input to charge compatible BLUETTI portable power stations while travelling or parked. It offers a more substantial charging route than a standard 12V accessory socket for suitably specified vehicle systems.
It connects to a 12V or 24V starter battery through its ALT port, accepts a solar input through its PV port, and charges a compatible power station through its CHG output. The unit can also connect to selected BLUETTI battery products through the BAT port and can be used with the optional DC Hub for fixed 12V or 24V loads.
Key features
- Up to 1,200W power-station charging output, with solar and alternator charging inputs.
- Up to 800W alternator input from a 12V or 24V vehicle starter-battery system.
- Up to 600W solar input; solar-panel open-circuit voltage must remain within 13V to 50V.
- Bluetooth and Wi-Fi app connectivity for charging-power, battery-status and energy-use monitoring.
- Reverse Charging, Trickle Charge and Pulse Maintenance functions for a connected vehicle starter battery, using solar panels or compatible BLUETTI products.
Where to use
The BLUETTI Charger 2 is suited to campervans, motorhomes, RVs, vans, trucks and mobile-work vehicles where a compatible power station needs charging while driving or from solar while parked. It can support portable power for equipment such as communications devices, laptops, lighting, refrigeration and other suitable loads.
When used with the optional BLUETTI DC Hub, the Charger 2 can supply compatible 12V or 24V DC appliances, such as a fridge, lighting, pump, fan, radio or Starlink equipment. Fixed vehicle wiring, starter-battery connections, fusing and smart-alternator D+ signal installation should be completed by a qualified automotive electrician or trusted installation partner.
