The Owner's Insights on the EcoFlow Alternator Charger Plus 1000W
I reckon an alternator charger is the easiest way to keep a power station full if you drive most days. The Plus 1000W takes up to 1000W off your alternator and puts it straight into your EcoFlow while you drive.
EcoFlow rates it at about 1kWh in an hour, in ideal conditions. That's roughly a day of running a 60L camp fridge, banked on the way to camp. The unit is a flat metal box, a bit bigger than a tablet, and it weighs 1.7kg.
It suits you if your station has an XT150 extra battery port and your rig is on the road most days. If you sit parked at camp for a week, solar will do more for you.
Why You'll Love the EcoFlow Alternator Charger Plus 1000W
- 1000W while you drive. About 1kWh into your station in an hour, so you arrive at camp with a full battery.
- Solar on the same box. Add the optional solar cable and run 700W from the alternator with up to 300W from your panels.
- Reverse charging. Your station can feed a flat starter battery, though it's a slow top-up and no instant jump start.
- 100W battery maintenance. It keeps your starter battery healthy on a long haul or when the rig sits.
- Ignition cable built in. The charger shuts down when the engine stops, so it won't drain your starter battery.
- CarPlay and Android Auto. Check your station's charge and starter battery voltage on the dash screen, or in the EcoFlow app.

Why You Should Consider an EcoFlow Alternator Charger
EcoFlow built its name on fast-charging portable power, and this charger fixes the slowest part of touring with a station. It carries a 2-year manufacturer warranty, with Australian support behind it. See the rest of the EcoFlow range or browse all portable power stations.

EcoFlow alternator charger 800W vs 1000W
The Plus 1000W replaces the older 800W and 500W chargers in our range. Against the 800W, you get 200W more charging power and a lighter 1.7kg body (the 800W weighs 2.3kg). You also get control through Apple CarPlay and Android Auto. Both charge while you drive and both run in reverse. If you drive long days, the extra 200W is where the time comes back.
What your power station needs for the 1000W alternator charger
The charger plugs into the XT150 extra battery port on your station. No XT150 port means no direct fit. A DELTA 2, DELTA 3, DELTA 3 Plus or DELTA 3 1500 takes the full 1000W. A DELTA 3 Max Plus, DELTA Pro 3 or DELTA Pro needs the Smart Generator Adapter to reach 1000W. Not sure about yours? Try the Power Station Finder or call the store.
How the EcoFlow 1000W alternator charger is installed
The charger wires to your starter battery through a 125A fuse, so it's a proper install. The box has a 5m input cable with an ignition lead, a 1m XT150 output cable, the fuse cable and the fasteners. Plenty of owners do the job themselves. It works from -10 to 45°C, so mount it away from exhaust and engine heat. If you're not comfortable near your starter battery, get an auto electrician to fit it.
Charging from solar and the alternator together
With the optional solar input cable, the charger takes up to 300W from solar panels. On a sunny day the alternator gives 700W and solar adds up to 300W, for 1000W in total. On a cloudy day, switch solar off in the app and the alternator can supply the full 1000W.
Two chargers on a DELTA Pro 3
EcoFlow says two Plus 1000W chargers can fill a DELTA Pro 3 in about 2.7 hours, which is 45% faster than one. That suits RV and van builds with big appliances. Ask the store about the adapter you'll need.
What's Included
- EcoFlow Alternator Charger Plus 1000W

- XT150 output cable (12AWG, 1m)
- 125A fuse cable (6AWG, 0.2m)
- Wall fasteners
- Manual and warranty card
What's Not Included

- Smart Generator Adapter (DELTA 3 Max Plus, DELTA Pro 3 and DELTA Pro)
- An auto electrician, if you'd rather not wire it yourself
Everything for a basic alternator install is in the box. The solar cable and the adapter are separate EcoFlow items, so ask the store if you need either.
Not Sure the Alternator Charger Suits Your Rig?
The Plus 1000W suits you if you drive most days and run an EcoFlow station with an XT150 port. It only charges while the engine is running, and your vehicle sets the ceiling, so 1000W is the most you'll see and not a promise on every drive. If your rig sits parked at camp for days, solar panels will do more for you. It carries a 2-year EcoFlow warranty, on top of your rights under Australian Consumer Law. Not sure it fits your station or your ute? Call the store on 03 7056 6732 and we'll check it with you before you buy.
