Product Features in Detail

EcoFlow Alternator Charger Plus 1000
To reach 1000W input, DELTA 3 Max Plus / DELTA Pro 3 / DELTA Pro must use theSmart Generator Adapter. DELTA 2/DELTA 3/ DELTA 3 Plus/DELTA 3 1500 support 1000W input directly. 

Faster – Top Up 1kWh in Just 1 Hour*
Charge as you drive – 10× faster than a traditional car cigarette lighter. Power up 1kWh in only 1 hour and arrive with a fully charged portable power station.
*Tested using a 12V car charging system at 25 ℃ ambient temperature. Actual performance may vary by vehicle and environment.

Alternator + Solar Flexible Dual Charging
By connecting solar directly to the alternator charger port, you free up the XT60 port on your portable power station. This allows you to use both the alternator charger and solar panels at the same time.
* To enable solar charging, the EcoFlowAlternator Charger Plus 1000 Solar Input Cable (12AWG, 5m)is required. 

Cloudy or Low-Sunlight Days
Turn off solar charging in the app to draw up to 1000W from the alternator alone.

Sunny Days
Turn on solar charging in the app to combine 700W from the alternator + up to 300W from solar, reaching a maximum of 1000W input.

Charge While You Drive, Power Anywhere
* To reach 1000W input, DELTA 3 Max Plus / DELTA Pro 3 / DELTA Pro must use theSmart Generator Adapter. DELTA 2/DELTA 3/ DELTA 3 Plus/DELTA 3 1500 support 1000W input directly. *Smart Generator Adapter ship in Mid-May.

Vehicle Conversions
Skip traditional hardwired 12V batteries and DC-to-DC chargers. With a power station + alternator charger setup, you get ultimate flexibility: power onboard systems while driving, then take your power outdoors for lighting, cooking, or tools.

Disaster Evacuation
When emergencies hit, restore your power station to full during the evacuation drive—even if it’s been sitting unused and partially discharged.

Reverse Charging for Car Battery Protection
Supports reverse charging* to the starter battery via the power station or solar panels. This helps maintain vehicle battery health and prevents draining.

Charging Mode–up to 1000W
Use when battery voltage is healthy. Charges the power station while driving.

Reverse Charging Mode–up to 1000W
- Pure Solar Charging Mode – up to 300W: Use without a power station connected. Supplies power directly from solar panels to the starter battery.
- Emergency Charging Mode – approx. 15A: Use when the vehicle battery is depleted and the engine won’t start. Functions as an alternative to a jump starter by slowly restoring the battery to normal voltage.

Battery Maintenance Mode–up to 100W
Use when starter battery voltage is low. Works as a battery maintainer, delivering steady current to extend starter battery lifespan.

Simpler – Smart Control via App or Infotainment
An industry first: supports car infotainment connectivity, compatible with Apple CarPlay and Android Auto interfaces
