EcoFlow battery charger 800W bidirectional Alternator Charger

With the 800W battery charger from EcoFlow (MPN: 305-24800), charging times for your power station in your car are reduced significantly. Unlike conventional car sockets, it charges up to 1kWh in just 1.3 hours while driving. Thanks to the advanced, integrated DC-DC converter, the charger makes optimal use of the energy generated while driving. Gallium nitride (GaN) technology offers excellent thermal resistance and guarantees safe charging in every application. In addition, it is equipped with several safety features, including undervoltage protection, which prevents excessive energy consumption and reliably protects your starter battery from damage. With the user-friendly app, you can easily switch between the three charging modes and monitor your system. You also get detailed insights into the power supply of your other devices. The practical plug-and-play design makes installation and operation easy. The charger is compatible with the DELTA series power stations.

How it works

The battery charger offers impressive charging power of up to 800W on the go. You can charge up to 1 kWh in just 75 minutes. Simply connect it to your vehicle's alternator, which delivers stable power during operation. The alternator not only supplies the vehicle's daily power requirements, but also generates surplus energy. The charger uses this extra energy efficiently through its integrated DC-DC boost converter to charge your portable power station quickly and reliably. This ensures that you always have a sufficient power supply, no matter where your journey takes you. Detailed installation instructions can be found in the download area.

Different modes for you

The integrated 3-in-1 battery maintenance solution ensures that your battery always remains in top condition. With the user-friendly EcoFlow app, you can conveniently monitor and control the charger remotely.

Charging mode - Input: 11-35V, 76A max. / Output: 40-60V, 800W max.
During your daily drives, the excess energy from the alternator is efficiently used to charge your power station. This ensures that it is always ready to go whenever you need it.
Battery maintenance mode - Input: 40-60V, 3A max. / Output: 13.8/27.6V, 100W max.
While parked, the system ensures a longer service life for your starter battery. A low maintenance current keeps the battery in optimal condition so that it remains ready to start at any time.
 

Reverse charge mode (jump start) - Input: 40-60V, 21A max. / Output: 13.8/27.6V, 800W max.
If the vehicle battery is too weak to start the engine, the power station kicks in. It reliably supplies the necessary transition current so that the engine starts smoothly and you can continue driving immediately.

An upgrade for your motorhome

In motorhomes, the system acts as an additional power generator and extends the runtime of your on-board battery. It can be easily connected to 12V or 24V motorhome batteries and seamlessly connected to the portable power stations. This protects your onboard batteries and increases your energy storage capacity by up to 7.2 kWh. (In the example with the DELTA Pro 3.6 kWh + additional battery 3.6 kWh)

Protection and safety

Gallium nitride (GaN) technology offers excellent thermal resistance and ensures safe charging in every application. The battery charger also has various safety features, including undervoltage protection, which prevents excessive energy consumption and reliably protects your starter battery from damage. Other features include reverse polarity protection, overcurrent protection, short-circuit protection, and overvoltage protection
