Description
1000W Alternator Charger with Solar Input, Automatic Ignition and 3 Operating Modes
The EcoFlow Alternator Charger Plus turns every journey into a charging opportunity. While you drive, excess energy from the alternator is converted directly into usable power for your EcoFlow portable power station, with up to 1000W of output. Ideal for motorhomes, caravans, campers, overlanding and off-grid travel, this charger is the ultimate solution for keeping batteries charged on the move.
Fast and flexible charging
✔ Up to 1000W of alternator charging while driving (XT150 cable included) ✔ Integrated solar input of up to 300W (11-60V, 15A) to charge even when stationary ✔ Dual charging: combine alternator up to 700W + solar up to 300W simultaneously ✔ 10x faster than a traditional cigarette lighter socket (1 kWh in approximately 1 hour) ✔ XT150 cable included, compatible with optional XT60 cable (up to 720W)
Three operating modes
The Alternator Charger Plus gives you full control over your vehicle’s energy management: Charging Mode: Charges the portable power station while driving, using excess alternator power. Up to 1000W output.
Reverse Charge Mode: If the vehicle battery runs down, you can use the power station to recharge it directly. Up to 1000W output (requires XT150 or 4+8 cable).
Maintenance Mode: Keeps the vehicle battery topped up with a slow 100W charge during long periods of inactivity, extending its service life.
Smart installation and full control
✔ Automatic ignition wire start: turns on automatically when the engine starts ✔ Compatible with Apple CarPlay and Android Auto for monitoring in the vehicle infotainment system ✔ EcoFlow app (iOS and Android) to monitor charge status, battery voltage and remaining time ✔ Tool-free connectors for quick installation and removal ✔ Fanless design with natural convection cooling ✔ IP4X dust protection for off-road use ✔ Angled input cable for easier routing in the vehicle

The Alternator Charger Plus 1000 is compatible with a wide range of power stations: ✔ EcoFlow DELTA 2, DELTA 2 Max, DELTA Max ✔ EcoFlow DELTA Pro, DELTA Pro 3 ✔ EcoFlow DELTA 3, DELTA 3 Ultra Plus, DELTA 3 Max Plus ✔ Other brands (Bluetti, Jackery, Anker) via XT60 cable (optional) ✔ Supports up to 2 units in parallel with DELTA Pro 3 for a combined 1700W
Usage example
On a 3-hour motorhome trip, the Alternator Charger Plus 1000 can fully charge a 1 kWh battery, leaving it ready to power lighting, a fridge and equipment when you arrive at your destination. With the additional solar input, you can keep charging even when parked at a campsite, using the sun during the day and stored energy at night, without relying on campsites or external power outlets.

Frequently Asked Questions
Do I need an additional hub or gateway?
No. The Alternator Charger Plus connects directly to the vehicle battery and the portable power station. App connectivity is via WiFi or Bluetooth, with no extra devices required.
Does it work with any vehicle?
Yes, it works with 12V and 24V systems. EcoFlow recommends keeping the vehicle’s total electrical load (including accessories and the charger) below 50% of the alternator’s rated capacity. Installation by a qualified professional is recommended.
Can I use it with solar panels at the same time?
Yes. The Alternator Charger Plus 1000 has a dedicated solar input (up to 300W) that can be used simultaneously with the alternator, freeing up the XT60 port on your power station for other uses.
Is it compatible with lithium batteries?
Yes, it is compatible with lithium and lead-acid starter batteries. The EcoFlow app guides you through the correct configuration for the battery and vehicle type.
Does it wear out the car’s alternator?
No. The Alternator Charger Plus uses only surplus power from the alternator. Intelligent detection of the starter battery voltage automatically adjusts the output based on the alternator model, driving conditions, and the vehicle’s electrical consumption, always operating within safe limits.
