EcoFlow Alternator Charger 800W

Q: What's the difference between the EcoFlow Alternator Charger 800W and the 500W?

The 800W charges roughly twice as fast as the 500W - it can fill a 1kWh battery in about 1.3 hours while you're driving. If you're running a DELTA 2 or DELTA Pro on a long haul and need a full charge by the time you pull up, the 800W is the one to get. The 500W suits shorter trips or lighter use.

Q: Does the EcoFlow Alternator Charger 800W work with any EcoFlow power station?

It's designed for the EcoFlow DELTA Series. If you've got a DELTA Pro, you'll need the adapter. It won't work with the RIVER Series - those run a different connector and charging profile.

Q: How does the EcoFlow Alternator Charger 800W actually work?

You wire it directly to your vehicle's alternator. While the engine's running, it pulls up to 800W from the alternator and pushes that straight into your DELTA power station via the XT150 cable. It's a permanent install - not a plug-in - so it charges while you drive without touching your starter battery. It also has a battery maintenance mode (100W) to keep your vehicle battery topped up when the car's sitting.

Q: Is the EcoFlow Alternator Charger 800W worth it?

If you're doing serious 4WD, overlanding, or working remotely from a ute, it's hard to beat. You're getting a full charge on your power station just from driving - no solar panel setup needed on the road. At $599 delivered, it's a solid investment if you're already running an EcoFlow DELTA and rely on it for tools, lighting, or camp power.

Q: How heavy is the EcoFlow Alternator Charger 800W and will it fit in a tight engine bay?

It weighs 2.3kg and measures 242 x 194 x 35mm - about the size of a large hardcover book and less than 4cm thick. It comes with an installation board and cable puller so you've got options for mounting. Most utes and 4WDs have enough room, but check your engine bay before ordering if it's already packed.

Q: What warranty does the EcoFlow Alternator Charger 800W come with?

It comes with a 2-year manufacturer warranty from EcoFlow Australia. We ship it to you Australia-wide with free delivery, and EcoFlow backs the unit directly for warranty claims.
