EcoFlow 800W Alternator Charger & Cable System

Never run out of power on your overland adventures or off-grid road trips. The EcoFlow 800W Alternator Charger Cable System is a game-changing DC-to-DC fast charging solution that harnesses excess energy generated by your vehicle’s alternator while driving. Delivering up to 800W of rapid charging power, this intelligent charger fills your portable power station up to 8 times faster than standard 12V vehicle cigarette lighter ports.

Rapid 800W On-The-Move Charging

Designed to maximize energy efficiency, the onboard DC-DC boost converter converts excess vehicle alternator power directly into usable DC power for your portable generator. Recharge a 1kWh power station (like the EcoFlow DELTA 2) in just 1.3 hours (75 minutes) while you drive. Skip the hassle of bringing heavy power stations indoors to charge before long journeys.

Innovative 3-in-1 Versatile Functionality

The EcoFlow 800W Alternator Charger goes far beyond standard battery chargers with its multifunctional 3-in-1 design:

1. Charge Mode (Up to 800W): Rapidly powers your EcoFlow DELTA power station or extra battery using your running vehicle’s engine power.

2. Reverse Charge Mode (Up to 800W): Recharges or boosts your vehicle’s starter battery or RV house battery using energy stored in your EcoFlow power station.

3. Battery Maintenance Mode (Up to 100W): Uses a small trickle current from your power station to keep your car’s starter battery healthy during extended stays, extending battery life and preventing dead batteries.

Built for Safety & Easy Vehicle Integration

Equipped with heavy-gauge 6 AWG wiring and heavy-duty cabling, this system is built to withstand extreme driving conditions and thermal stress. Built-in comprehensive safety protection safeguards against overvoltage, undervoltage, short circuits, reverse polarity, and overcurrent. With smart app integration over Wi-Fi and Bluetooth, you can monitor charging speeds and switch modes right from your smartphone.

Frequently Asked Questions (FAQs)

Q1: Is the EcoFlow 800W Alternator Charger compatible with all EcoFlow Power Stations?

It is directly compatible with EcoFlow DELTA series power stations and extra batteries using the XT150 connection port (e.g., DELTA 2, DELTA 2 Max, DELTA Pro with appropriate adapter).

Q2: Will using this charger drain my vehicle’s starter battery when the engine is off?

No. The EcoFlow Alternator Charger detects vehicle status and will automatically switch off or pause charging when the engine isn’t running, preventing accidental starter battery drain.

Q3: Can I use this system to jump-start or charge my car battery?

Yes! In Reverse Charge Mode, energy stored in your EcoFlow portable power station flows back to charge or jump-start your 12V or 24V vehicle starter battery at up to 800W.

Q4: How is the cable connected during installation?

The input cable connects directly to your car’s main 12V/24V starter battery or alternator through an inline 125A fuse cable. The XT150 output cable plugs directly into the input/extra battery port of your EcoFlow power station.

Q5: Can I control the charger using my phone?

Yes. The built-in Bluetooth and Wi-Fi modules allow you to monitor charging speeds, adjust output levels, and switch between Charge, Reverse Charge, and Maintenance modes via the official EcoFlow mobile app.
