Reverse charging and battery maintenance modes require a compatible EcoFlow DELTA series model and either an XT150 or 4+8 output cable. These features are not supported while using the XT60 output cable or any third‑party power station. For a full breakdown of how these modes work, see my detailed full review.

Third-Party Power Station Compatibility

Want to use an EcoFlow Alternator Charger with your BLUETTI, Jackery, Anker or other brand solar generator? Use my compatibility calculator to verify support and see expected charging power. If your solar input port is already in use or needs an XT60 adapter, you'll find solutions in the sections below.

What are the specifications for your solar input port?

Third-party battery (15V~24V)

Set the input voltage range of the power station.

15V

24V

11V60V

Important: Charging third-party power stations requires the XT60 output cable. This cable is included with the 500W Alternator Charger, but must be purchased separately for the 800W model.

Actual output may be lower depending on your setup. Alternator size, battery voltage (12V vs 24V), vehicle battery health, and ambient temperature can all affect performance. Your power station’s minimum start‑up voltage may also limit the charging rate.

More details: My alternator charger guide covers alternator load, smart alternators, idling vs driving, and real‑world charging performance. It also compares chargers across all major brands so you can choose the setup that works best for you.

XT60 port already in use?

If you only have one XT60 port and already use it for solar panels, you have two options:

Use the upcoming Alternator Charger Plus 1000: This model includes a built‑in solar controller, allowing your solar panels and the alternator charger to operate at the same time through separate inputs.
- Solar Specs: The solar input on the Plus 1000 accepts 11-60V⎓15A (300W max)
- Accessories Required: EcoFlow Solar Input Cable and EcoFlow XT60 Output Cable.
Manual Swapping: Manually unplug your solar panels and plug in the alternator charger when driving.
Pro Tip: To prevent wearing out your power station’s internal port from frequent unplugging, use a short XT60 extension cord.

Don't have an XT60 port?

While XT60 is the standard for most modern portable power station and solar generators, some brands or older models use different connectors. If your unit doesn’t have an XT60 port, you can usually use an adapter for the connection. You will need an XT60 male adapter rated for at least 12A to connect to the alternator charger.

XT60 Male (pins are male)

Pro Tip: Use a short XT60 adapter. Long or thin‑gauge cables can cause voltage drop, which may impact charging performance or prevent charging from starting on some power stations that have a high minimum voltage.

Are EcoFlow Alternator Chargers compatible with third-party power stations?

Yes, EcoFlow Alternator Chargers are compatible with many third-party power stations (such as Jackery, BLUETTI, and Anker) via the XT60 output cable. This cable is included with 500W and 600W models but sold separately for the 800W and Plus 1000. If your unit uses a different connector such as Anderson, 8mm, or MC4 ports, you can connect using a high-quality XT60 adapter. Ensure your power station’s solar input voltage range is compatible with the charger's output. Also note that "Reverse Charge" and "Battery Maintenance" modes are exclusive to compatible EcoFlow DELTA series units using XT150 or 4+8 cables.

Can I use solar and alternator charging at the same time?

Yes, you can use solar and alternator charging at the same time as long as your solar generator supports multiple DC inputs or you’re using the Plus 1000 model. Many EcoFlow and third‑party units can combine both sources through separate solar ports, while the Plus 1000 adds its own 11–60V solar input (300W max) for simultaneous charging without needing an extra port.

Does the 800W charge faster than the 500W model when using an XT60 cable?

No, the 800W and 500W models both charge at 500W when using the XT60 output cable. additionally, your actual charging speed is also impacted by your power station’s input specifications. If your station is limited to 500W or approximately 10A, both chargers will perform identically. To unlock the 800W model’s full 800W potential, you must use the XT150 or Custom Fit (4+8) output cable with a compatible EcoFlow DELTA series unit.

Why am I not reaching the full 500W or 800W charging speed?

Maximum charging speeds are limited by your portable power station’s input specifications, the output cable used, and additional factors such as alternator size, vehicle battery health, and high ambient temperatures. To reach full speeds, ensure you are using an XT150 or Custom Fit (4+8) cable with a compatible high-input EcoFlow power station and a healthy vehicle electrical system capable of sustained high-current output.

Can I use the "Reverse Charge" feature with a non-EcoFlow power station?

No, the "Reverse Charge" and "Battery Maintenance" features are only supported with a compatible EcoFlow DELTA series unit while using the XT150 or Custom Fit (4+8) output cable. Most power stations' solar input ports are physically incapable of exporting power to the charger. Therefore, EcoFlow restricts these features to the XT150 or 4+8 output cables.

What happens if my portable power station has a maximum input voltage below 24V?

Connecting a portable power station with a maximum input voltage below 24V is incompatible and poses a risk of hardware damage. If the charger’s output voltage exceeds your power station's input limit, it could trigger an over-voltage protection (OVP) error or, in units lacking protective circuitry, permanently damage the internal charge controller. Always verify your power station’s "Max Volts" specification and use the EcoFlow app to set a custom max voltage limit between 24V and 60V.

Vehicle Compatibility

Both the 500W and 800W models accept a wide input range of 11V–31V, making them compatible with standard 12V (default) passenger vehicles and 24V systems found in heavy-duty trucks or RV house batteries.

Automatic Voltage Detection: The chargers feature automatic voltage detection to determine when to start charging. While they have a preset threshold, it is highly recommended to manually configure the start-voltage value in the app to match your specific vehicle. This ensures charging begins when the engine starts and stops reliably when the engine is off, to prevent draining your starter battery.
Smart Alternator Support: Because the 500W and 800W models lack a physical ignition sensing wire, they rely exclusively on voltage monitoring. In vehicles with smart alternators, charging may temporarily pause during fuel-saving voltage drops and resume once the voltage climbs.
