EcoFlow battery charger 800W bidirectional Alternator Charger

With the 800W battery charger from EcoFlow (MPN: 305-24800), the charging times for your power station in your car are reduced many times over. 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 optimum use of the energy generated while driving. The gallium nitride (GaN) technology offers excellent thermal stability and guarantees safe charging for every application. It is also 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 & play design enables easy installation and operation. The charger is compatible with the DELTA series power stations.

How it works

The battery charger offers an 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 provides stable power during operation. The alternator not only supplies the vehicle's daily power requirements, but also generates surplus energy. The charger uses this additional energy efficiently with its integrated DC-DC boost converter to charge your portable power station quickly and reliably. So you are always well supplied with energy, no matter where your journey takes you. You can find detailed installation instructions in the download area.

Different modes for you

The integrated 3-in-1 battery care solution ensures that your battery is always 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 rides, the surplus energy from the alternator is used efficiently to charge your Powerstation. This means it is always ready to start and ready for use whenever you need it.
Battery maintenance mode - input: 40-60V , 3A max. / output: 13.8/27.6V , 100W max.
During parking, the system ensures a longer service life for your starter battery. A low float current keeps the battery in optimum condition so that it remains ready to start at all times.
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 Powerstation steps 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 on-board batteries and increases the 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

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