EcoFlow 800W Alternator Charger for Portable Power Stations

The EcoFlow 800W Alternator Charger converts surplus electrical power generated by a compatible vehicle alternator into fast charging power for selected EcoFlow portable power stations.

Delivering up to 800W charging output, the charger can add approximately 1kWh of stored energy in around 1.3 hours under suitable vehicle and operating conditions.

Product Description

The EcoFlow 800W Alternator Charger provides a fast and efficient way to recharge a compatible EcoFlow portable power station while travelling.

Traditional vehicle accessory sockets typically provide relatively low charging power. The Alternator Charger connects directly to a compatible vehicle starter battery and uses surplus electrical power generated by the alternator while the engine is running.

Its integrated DC-to-DC power converter regulates the available power and can supply up to 800W to a compatible EcoFlow portable power station or extra battery.

Under suitable vehicle and operating conditions, the charger can add approximately 1kWh of stored energy in around 1.3 hours. This is up to eight times faster than conventional vehicle accessory-socket charging.

The charger supports three operating modes when connected to compatible bidirectional EcoFlow equipment: Charging Mode, Reverse Charging Mode and Battery Maintenance Mode.

Charging Mode uses surplus alternator power to recharge the connected EcoFlow portable power station while the vehicle engine is running.

Reverse Charging Mode allows a compatible EcoFlow power station to supply controlled power back to a supported vehicle starter battery or RV house battery at up to 800W.

Battery Maintenance Mode provides lower-power charging of up to 100W to help maintain the voltage of a compatible starter or house battery.

The reverse-charging function may assist with restoring energy to a low vehicle battery. The Alternator Charger should not be treated as a conventional direct-cranking jump starter.

The charger supports compatible 12V and 24V vehicle electrical systems and is suitable for selected SUVs, 4×4 vehicles, pickup trucks, vans, caravans, motorhomes and RVs.

Wi-Fi and Bluetooth connectivity allow charging power, operating modes, status information and selected settings to be monitored through the EcoFlow App.

Professional installation by a competent vehicle electrician or installer is recommended because the charger connects directly to the vehicle starter battery and carries high electrical current.

Specifications

Compatibility

The included 1m XT150 output cable is designed for compatible EcoFlow portable power stations and Extra Batteries featuring a supported XT150 extra-battery port.

Direct XT150-compatible products may include:

• EcoFlow DELTA 2
• EcoFlow DELTA 2 Smart Extra Battery
• EcoFlow DELTA 2 Max
• EcoFlow DELTA 2 Max Smart Extra Battery
• EcoFlow DELTA Max 2000

EcoFlow DELTA Pro

The included XT150 output cable does not connect directly to the EcoFlow DELTA Pro.

Connecting the Alternator Charger to DELTA Pro requires the separately sold:

• EcoFlow DELTA Pro to Smart Generator Adapter

Confirm that the required adapter is included when purchasing a product bundle.

EcoFlow DELTA 3 Max

The included XT150 output cable does not connect directly to the EcoFlow DELTA 3 Max.

Connecting the Alternator Charger to DELTA 3 Max requires the separately sold:

• EcoFlow Alternator Charger XT60 Output Cable

The XT60 Output Cable may be included when the DELTA 3 Max and Alternator Charger are purchased together as an official bundle.

When connected to DELTA 3 Max through the XT60 Output Cable:

• The Alternator Charger can charge the DELTA 3 Max
• Reverse charging to the vehicle battery is not supported
• The connection should be treated as a power-station charging configuration
• Do not rely on Reverse Charging or Battery Maintenance Mode with this connection

Other EcoFlow Products

Products without a compatible XT150 port may require a separately sold model-specific output cable or adapter.

Before ordering, confirm:

• The EcoFlow power-station model
• The charging-port type
• Whether alternator charging is supported
• The required output cable or adapter
• The maximum charging input accepted by the power station
• Whether Reverse Charging Mode is supported
• Whether Battery Maintenance Mode is supported

The charger is designed for suitable vehicles equipped with a compatible 12V or 24V starter battery and alternator system.

Potential vehicle applications include:

• SUVs
• 4×4 vehicles
• Pickup trucks
• Vans
• Caravans
• Motorhomes
• RVs
• Overlanding vehicles
• Mobile work vehicles
• Vehicles with compatible auxiliary batteries
• Vehicles with compatible house-battery systems

Petrol and diesel vehicles fitted with conventional alternators are generally the most suitable.

Some vehicles with smart alternators, advanced battery-management systems, hybrid systems or specialised electrical systems may provide reduced charging performance or require additional configuration.

Pure electric vehicles do not use a conventional engine-driven alternator and should not be assumed compatible.

Actual charging output depends on:

• Vehicle alternator capacity
• Available surplus alternator power
• Engine speed
• Vehicle electrical load
• Starter-battery voltage
• Smart-alternator behaviour
• Charger power settings
• Cable installation
• Ambient temperature
• Connected EcoFlow product
• Portable power-station battery level
• Portable power-station input limits

The maximum 800W output is not guaranteed in every vehicle or under every operating condition.

Professional installation by a competent vehicle electrician or installer is recommended.

Before installation, confirm any vehicle-warranty implications with the vehicle manufacturer, dealership or warranty provider.

The charger must be installed away from:

• Excessive engine heat
• Exhaust components
• Fuel lines
• Moving mechanical parts
• Sharp edges
• Areas where water may collect
• Airbags
• Vehicle safety systems
• Areas where luggage may damage the cables
• Poorly ventilated or enclosed spaces

Incorrect installation may result in cable overheating, electrical short circuits, blown fuses, product damage, vehicle damage, fire or personal injury.

Sustainability

The EcoFlow 800W Alternator Charger uses surplus electrical power generated by a compatible vehicle alternator to recharge selected portable power stations while driving.

Its DC-to-DC charging system can reduce the need to return to a mains power connection between trips, while Battery Maintenance Mode can help maintain a compatible vehicle starter battery or RV house battery when used with supported bidirectional equipment.
