3. Ground the negative (black) terminal of the Input Cable (B) to the vehicle's chassis or the RV house battery's negative (-) terminal.
4. Connect the Input Cable (B) to the Vehicle Battery Port on the charger (A).
5. Connect the XT150 Output Cable (C) from the charger's Portable Power Station Port to the extra battery port of the power station or extra battery (F).

Ensure all cables are connected firmly to prevent melting.

Compatibility

Vehicle Starter Battery or RV House Battery

The vehicle starter battery or RV house battery must be undamaged and rechargeable. The nominal voltage should be 12V or 24V.

Car Model Requirements: For older or special car models with lower overall voltage, the charger may not function correctly. Use the EcoFlow app to adjust the charger's start voltage if needed.

Portable Power Station or Extra Battery

The 800W Alternator Charger connects to the extra battery port (XT150) of an EcoFlow portable power station or extra battery using the XT150 Output Cable. Ensure your power station or battery has this port.

Environmental Requirements

To ensure normal operation, the charger's location must meet the following requirements:

1. Be near the portable power station or extra battery, as the Output Cable is only 1m long and cannot be extended.
2. Have adequate connection space around the ports.
3. Be dry and tidy, with a moderate temperature, and away from heat sources.
4. Be away from flammable substances, as the charger generates heat during use.
5. Be well-ventilated; do not cover the charger with blankets or anything that obstructs ventilation.
6. Keep away from children and pets.

Installation (Optional)

For smooth rides, the charger can be placed on the power station. For bumpy rides, secure installation is recommended.

Note: Do not flush mount the product to ensure proper ventilation.

Switching Mode and State

Modes can be changed by navigating to the device detail page in the app and tapping a mode icon.

Switch between working or standby states by tapping the toggle button in the app.

Operating Modes

Charge Mode

• Power Flow: Alternator ➡️ Vehicle Starter Battery or RV House Battery ➡️ Alternator Charger ➡️ Portable Power Station or Extra Battery.
• Maximum Power: 800W.

When the vehicle is in motion and the power station/extra battery is powered on, the charger utilizes the alternator's power to charge the connected device. Actual output power varies with vehicle motion and model. To prevent starter battery over-discharge, the charger monitors battery voltage and stops if it falls below the start voltage. If idle in Charge Mode for over 48 hours, the charger will automatically power off. For driving safety, avoid changing modes while the vehicle is in motion.

Battery Maintenance Mode

• Power Flow: Portable Power Station or Extra Battery ➡️ Alternator Charger ➡️ Vehicle Starter Battery.
• Default Maximum Power: 100W.

This mode keeps your starter battery optimally charged over extended periods, extending its lifespan and ensuring readiness.

Reverse Charge Mode

• Power Flow: Portable Power Station or Extra Battery ➡️ Alternator Charger ➡️ Vehicle Starter Battery or RV House Battery.
• Maximum Power: 800W.

When the power station/extra battery is powered on, the charger uses it to charge the vehicle starter battery or RV house battery with up to 800W.

Unplugging Cables

To unplug the Input Cable or Output Cable:

1. Power off the portable power station or extra battery.
2. Power off the charger.
3. Use the included cable puller to unplug the cable.

Troubleshooting

LED Indicator is Red

• Check app interfaces for error details.

Wiring is Complete but Charger Won't Power On

• Ensure correct polarity between the charger and the vehicle starter battery or RV house battery.
• Verify all cable terminals are connected firmly.
• Confirm the vehicle starter battery or RV house battery voltage is 12V or 24V.
• If the Input Cable's negative terminal is connected to the starter battery's negative terminal, connect it to the chassis instead and try powering on again.

In Charge Mode, the Power Station or Extra Battery Won't Charge

• Upgrade the firmware of your portable power station or extra battery to the latest version via the app.
• Check if a charge limit is set for your power station in the app.

Output Power Does Not Reach Maximum

• Check if the output power is set correctly in the app.
• The alternator's output might be low. Try boosting it (e.g., by pressing the accelerator) and then try again.

In Charge Mode, Output Power Fluctuates Dramatically

• This may occur if a battery sensor module is connected to the starter battery's negative terminal. Connect the Input Cable's negative terminal to the chassis and try again.

Power Station or Extra Battery Turns Off After Charger Enters Standby

• Upgrade the firmware of your portable power station or extra battery to the latest version in the app.

Connected WAVE 2 Add-on Battery Won't Charge

When a WAVE 2 add-on battery is connected, the charger initiates device recognition (approx. 1 minute). Charging begins after recognition. If the issue persists, contact technical support.

Maintenance
