Automatic Charging: Automatically controls charging using intelligent voltage detection or an optional ignition wire so it only operates when the vehicle is running.
Multifunctional: In addition to charging, when connected to a compatible BLUETTI power station it also offers reverse charging and battery maintenance for the vehicle's battery.
Broad Compatibility: Basic charging and solar also work with many third‑party models from brands like EcoFlow and Jackery. This flexibility makes it a versatile option for mixed‑brand power setups.
Smart App Control: Monitor energy flow and adjust charging settings in real time via the BLUETTI app.
Backwards Compatible Wiring: Designed as a true drop‑in upgrade for Charger 1 users. Existing wiring can stay in place, which makes upgrading fast, clean, and hassle‑free.
Configurable Charging Power: You can manually throttle the wattage to a desired level, making it compatible with smaller alternators or specific batteries.
What's New
Increase in Charging Power: Delivers a significantly higher charging rate compared to the previous generation, supporting up to 800W of input from the alternator (at 12V or 24V) for a combined total charging power of up to 1,200W maximum when paired with solar and using power station port.
Bidirectional Port: A bidirectional port (BAT) designed for connecting a BLUETTI power station with an expansion port or a BLUETTI expansion battery
Solar Input: Now features a dedicated 600W solar input (PV) with a voltage range of 13-50V. This allows you to charge your power station from solar panels while stationary or supplement the alternator while driving.
DC Hub Port: Expand into a complete DC power distribution center by adding the DC Hub. This provides nine extra DC output ports, including a 50A Anderson port, cigarette lighter, USB-C PD, and USB-A. Requires a BLUETTI device connected to the bidirectional port to be active when the vehicle is off.
Two Power Stations: Supports charging two power stations simultaneously: one through the power station port (CHG) and the other through the bidirectional port (BAT).
Ignition‑Triggered Auto Start: Can be configured to automatically power on when the vehicle's ignition is engaged via a built-in ignition wire (D+) to the vehicle's ACC/IGN fuse box. This is a major improvement, especially for vehicles with smart alternators, as it ensures the charger only draws power when the engine is running.
