Brings your alternator, starter battery, power station, solar panels, DC hub, and auxiliary batteries together into one smart ecosystem. Enjoy less effort, faster charging and better energy management. Find more confidence while you're driving, camping, or off-grid

Charger 2 is your central power hub. It automatically balances power input and output, and reverse-charges your vehicle system based on real-time conditions and your preferences.

Easily charge your BLUETTI power stations from your vehicle, solar panels, or another BLUETTI unit using a bi-directional cable.

If your car battery runs low, Charger 2 can safely recharge it using solar power or a BLUETTI power station or expansion battery, so you never get stranded.

Power your DC devices while driving, and when the engine shuts off, Charger 2 switches to other sources to keep your devices running and prevent draining your car battery.

1,200 W Alternator + Solar Charging

Get up to 1,200 W from your vehicle and solar panels — charging 13× faster than a standard car outlet and 2× faster than Charger 1. Choose one source or both without switching or unplugging, and stay fully powered on the road or off-grid with zero hassle.

Fits BLUETTI & Beyond

Compatible with all BLUETTI models and most other power stations. Easy to set up now and ready for whatever you add later.

12 V/24 V DC Output via DC Hub

Up to 600 W of dual-voltage power — no boost modules, no messy wiring. Run your car fridge, lights, fans, or any 12 V/24 V device seamlessly. Just plug in and go.

*Note: Requires Anderson adapter cable for DC panel connection; DC Hub does not include a DC panel.

Stay safe with built-in safeguards, including temperature control, over-voltage, over-current, and low-voltage protection.

Charging starts when you drive and stops when you park. No manual control. No impact on your vehicle's starter battery.

Seamlessly communicates with smart alternators using D+ signal support for smoother, more efficient charging.

In Full Control

Take control of your energy with the BLUETTI app. View system status, track energy use, and manage everything in real time, from anywhere. Plus, it automatically recognizes connected power stations and adjusts settings for a seamless, hassle-free experience.
