Want to recharge your power station 8× faster on the road? The EcoFlow 800W Alternator Charger makes every drive a chance to power up
The EcoFlow 800W Alternator Charger is built for travellers, campers, and anyone who needs serious charging power while on the move. Instead of waiting hours at a wall outlet, this smart charger restores your EcoFlow power station using energy already produced by your vehicle, giving you freedom and speed like never before.
With the 800W Alternator Charger, you can charge up to 8 times faster than through a standard vehicle auxiliary outlet. That means you can fully recharge your power station in just 1.3 hours. Whether you’re on a long trip or a short drive, every kilometre counts towards keeping your devices, appliances, and essentials powered.

It’s not just powerful, it’s versatile too. The 800W Alternator Charger adapts easily to 12V and 24V RV house batteries, connecting directly to EcoFlow portable power stations. It also helps protect your RV batteries while expanding your energy storage capacity by up to 7.2kWh when paired with systems like the DELTA 3 Pro and Extra Battery.
Key Features of the 800W Alternator Charger

Please note that if you need to connect the 800W Alternator Charger to the DELTA Pro, you will need to purchase the DELTA Pro to Smart Generator Adapter separately. Alternatively, you can opt for the DP+800W bundle, which already includes the Adapter, so there's no need to buy it separately.
