What Is the BLUETTI Charger 2?
The BLUETTI Charger 2 is a DC-to-DC alternator charger designed to recharge compatible BLUETTI portable power stations directly from your vehicle.
Instead of using a slow cigarette lighter outlet, it connects to your vehicle’s electrical system to take advantage of unused alternator capacity while the engine is running.
This allows significantly faster charging during road trips.
