Frequently Asked Questions - RIVER Pro ECOFLOW

What is the battery capacity of the RIVER Pro?

The capacity is 768 Wh (40 Ah at 19.2 V) with a Lithium Iron Phosphate (LFP) battery.

Can the station be recharged with solar panels?

Yes, via the solar input (11-50 V, 13 A, 220 W max). A full charge takes about 4.5 to 9 hours with a suitable solar panel.

What is the X-Boost function?

X-Boost allows powering devices with a rated power up to 1600 W (instead of the standard 800 W). Ideal for resistive or motor-driven devices.

Which devices cannot be plugged into the AC output?

Avoid devices requiring 0 ms switching (UPS for servers) and vital medical devices like hospital respirators. Check compatibility via the app.

Can I take the RIVER Pro on a plane?

No, the battery capacity exceeds the limits allowed for air travel (usually 100 Wh).

How to maintain the battery for a long lifespan?

Store it at 20-30°C with a 60% charge. Fully discharge it then recharge to 60% every 3 months. Avoid leaving it discharged for more than 6 months.

What to do if the screen displays an overload warning?

Immediately unplug the overpowered devices. Restart the station. If the warning persists, contact EcoFlow customer service.

Can I use the station while it is charging?

Yes, the EPS function automatically switches to battery in less than 30 ms in case of grid failure. The outputs remain active.

What is the maximum charging power via USB-C?

The USB-C input and output support up to 100 W (20 V, 5 A).

How to change the AC output frequency (50/60 Hz)?

Hold down the AC output switch for 10 seconds to toggle between 50 and 60 Hz, or use the EcoFlow app.

17. This product is not recommended for powering medical emergency equipment related to personal safety, including but not limited to medical grade ventilators (hospital version CPAP: Continuous Positive Airway Pressure), artificial lungs (ECMO: Extracorporeal Membrane Oxygenation). It can normally work with a home ventilator (home version CPAP), and does not have to be continuously monitored by professionals. Please follow your doctor's

instructions and consult with the manufacturer for restrictions on the use of the equipment. If it is used for general medical equipment, please be sure to monitor the power status to ensure that the power does not run out.

1. When in use, power supply products will inevitably generate electromagnetic fields, which are likely to affect the normal operation of medical implants or personal medical equipment such as pacemakers, cochlear implants, hearing aids, defibrillators etc. If these types of medical equipment are being used, please contact the manufacturer to inquire about any restrictions on the use of such equipment. These measures are fundamental to ensure a safe distance between the medical implants (for example, pacemakers, cochlear implants, hearing aids, defibrillators, etc.) and this product while in use.
2. When the power supply is connected in the normal mode to a refrigerator, the power supply may be automatically shut down due to the power fluctuation property of the refrigerator. If the refrigerator stores medicines, vaccines or other high-value items, it is highly recommended that you set the AC output to "Never Turn Off" through the APP when connecting the power supply product to ensure continuous power supply. Users should pay attention to the power consumption of the power supply.
3. Do not put fingers or hands into the product.
4. To reduce risk of damage to the electric plug and cord, pull the plug rather than the cord when disconnecting the power pack.
5. Do not operate the power pack with a damaged cord or plug, or a damaged output cable.
6. To reduce the risk of electric shock, unplug the power pack form the outlet before attempting any instructed servicing.
7. Have servicing performed by a qualified repair person using only identical replacement parts. This will ensure that the safety of the product is maintained.
8. Do not use a battery pack or appliance that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.

Additional Features

X-Boost

The product supports X-Boost. It can power devices rated at up to 1600W without incurring operation failure due to overload protection. Observe the following tips when using the X-Boost feature:

1. The X-Boost feature is not suitable for appliances with voltage protection (such as precise instruments).
2. It is suitable for heating and motor devices. Please conduct your own tests to check whether your devices support X-Boost.

EPS

The product supports emergency power supply (EPS). When you connect the grid power to the AC input port of the product through an AC cable, you can power electrical devices through the AC output port (AC power will come from the grid instead of the power station in this situation). In case of a sudden blackout, the product can automatically switch to the battery-powered supply mode within 30ms.

As a basic UPS feature, the EPS does not support 0ms switching. Please do not connect the product to any device that requires 0ms UPS (such as data servers and workstations). Please test and confirm the compatibility before using the product. We recommend that you charge only one device (with maximum power < 1000W and AC input ≥ 110V ) at a time and do not use multiple ones at the same time to avoid triggering overload protection. EcoFlow takes no responsibilities for any device failure or data loss caused by failure to follow instructions.
