Description
The EcoFlow 800W Alternator Charger is an EcoFlow charger that tops up a power station from the car’s alternator while you drive, at up to 800 W. That is eight times more than a cigarette lighter socket: the station gets 1 kWh in about 1.3 hours on the road. If you want to buy EcoFlow 800W Alternator Charger for a car, camper or work van, below we explain how it works and what installation involves.
How it works
The charger connects to the car’s starter battery and its output goes to the station. While the engine runs, the alternator produces more power than the car needs, and the Alternator Charger passes this surplus to the station. According to EcoFlow, the charging logic does not force 800 W: the power depends on the alternator’s headroom, so the alternator is not overloaded and the effect on fuel consumption is minimal.
Three modes
Fast station charging
Up to 800 W at an input voltage of 11-31 V, that is, for vehicles with 12 V and 24 V systems. Input current up to 76 A.
Car battery maintenance
When the car stands for a long time, the charger can top up the starter battery from the station at up to 100 W so that it does not run down.
Reverse charging
If the car battery is flat, the station sends up to 800 W into it through the Alternator Charger. EcoFlow notes that maintenance and reverse charging work through the XT150 cable and only with DELTA stations.

Compatibility
An XT150 cable for DELTA stations is included. It works with, among others, the EcoFlow DELTA 2, EcoFlow DELTA 2 Max, EcoFlow DELTA 3, EcoFlow DELTA 3 Plus and EcoFlow DELTA 3 1500.
DELTA 3 Max Plus, DELTA 3 Ultra Plus, DELTA Pro and DELTA Pro 3 need a separate EcoFlow DELTA Pro to Smart Generator Adapter. For reverse charging and battery maintenance with these stations, EcoFlow also lists a separate 2 m Custom Fit Output Cable; ask us about its availability.
RIVER and other stations with an XT60 input connect through an XT60 cable bought separately. In that case only the charging mode works.
Installation
The charger is mounted in the cabin or the boot, and its wires run to the car battery. According to EcoFlow, no drilling of the body is needed; the wiring can be routed through the firewall. Users with hands-on experience can install it themselves, but EcoFlow recommends turning to professionals. Before buying, check in the car’s manual that the alternator has enough spare capacity, and ask the car manufacturer about the warranty.
FAQ
Does the charger harm the alternator or the car battery?
According to EcoFlow, no: it only takes the alternator’s surplus and does not overload it.
How does it differ from the 500W Alternator Charger?
The 800 W version is twice as fast and comes with an XT150 cable. The EcoFlow 500W Alternator Charger is cheaper and comes with an XT60 cable, without reverse charging over XT60.
How do I order?
The charger is available to order. You can buy EcoFlow 800W Alternator Charger on its own or together with a DELTA station, and we will tell you what your model needs.
