2. If the product is not used for 5 minutes, it will enter hibernation state with the LCD screen gone off.
3. When RIVER 2 Pro is charging, it can't be turned off by pressing and holding the main power button unless the charging cable is unplugged first.

Charge Your Devices

The USB-A and USB-C output ports are automatically turned on once the product is turned on. Press the "DC output switch" or "AC output switch" once to turn on their corresponding DC/AC output sockets; press again to turn them off.

When using the AC output socket, make sure that the sum power of all loaded devices is less than the rated power.

Charge RIVER 2 Pro

AC Charging (Grid Charging)

1. For AC charging, we recommend that you use a power socket with a capacity of more than 10A and ensure that the working current of the socket is constantly greater than 10A.
2. For AC charging, please use the AC charging cable included in the package and plug the cable directly into a wall outlet instead of an extension socket.

Solar Charging

1. The solar charging cable (MC4-XT60 adapter cable) and the solar panel are supplied separately.
2. When using an EcoFlow solar panel to charge the product, connect them according to the instructions in the user manual.
3. Before connecting the solar panel, ensure that the output voltage of the solar panel is less than 50 V to avoid product damage.

Car Charging

You can recharge the product through the car power outlet. The product supports 12V/24V car chargers and a maximum charging current of 8A.
Please charge using the car charger after the car is started to avoid failure to start due to insufficient car battery. In addition, please make sure that the car power outlet is securely connected to the cigarette lighter of the car charger input cable.
EcoFlow takes no responsibilities for any loss or damage caused by failure to follow instructions.

USB-C charging

The USB-C charging cable (Type-C plug) and adapter are supplied separately.

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.

Troubleshooting

Indicator	Problem	Solution
Flashing	Battery discharge low temperature	Normal operation will resume automatically when the battery warms up.
Flashing	Battery discharge high temperature	Normal operation will resume automatically after the battery cools down.
Flashing	Battery charging low temperature	Normal operation will resume automatically after the battery temperature is restored to above 3°C.
Flashing	Battery charging high temperature	Normal operation will resume automatically after the battery cools down.
Flashing	AC output low temperature	Normal operation will resume automatically when the product warms up.
Flashing	AC output high temperature	Ensure that the air inlet and outlet of the product are unobstructed. Normal operation will resume automatically after the temperature decreases.
Flashing	USB-C or car charging output overload	Remove overpower devices and restart the product to resume normal operation.
Flashing	AC output overload	Remove overpower devices and restart the product to resume normal operation. The sum power of loaded electrical appliances must not exceed the rated power (for the power limit of electrical appliances in the X-Boost mode, please refer to the X-Boost feature introduction).
Flashing	Charging overload	Remove the charging cable and normal operation will resume automatically after restart.
Flashing	Fan blocked	Check whether the fan is blocked by foreign objects.
Flashing	Failure of communication between main control board and AC	Normal operation will resume automatically after restart.

If a warning is prompted during the use of the product and the warning icon persists after restart, please stop using the product immediately (do not attempt to charge or discharge it). For problems not covered in the preceding table, please consult EcoFlow customer service.

FAQ

What battery does the product use?

High-quality LFP battery.

What devices can the product's AC output socket power?

The rated power of the product is 800W and the peak power is 1600W. With the X-Boost feature, the product's AC output sockets can power devices rated at 1600W or below. We recommend that you confirm the power of devices before use, and ensure that the sum power of all loaded devices is less than the rated power.

How do I know how long the product can charge my devices?
The charging time is shown on the product's LCD screen, which can be used to estimate the charging time of most appliances with stable power usage.

How do I know if the product is charging?

During charging, the remaining charging time is shown on the LCD screen. Meanwhile, the circle indicator around the remaining battery percentage rotates and the input power is shown.

Can I take the product on a plane?

No.

Can I switch the frequency of the product?

We recommend that you do not switch the frequency in general cases. If you need to switch the AC frequency due to special circumstances, please turn on the AC power, and then press and hold the AC output switch for 10 seconds or use the app to switch frequency.

Care and Maintenance

1. For safety, please do not store the product in an environment temperature higher than 45°C or lower than -10°C for a long time.
2. For long-term storage, please recharge the product every three months (firstly discharge it to 0%, then recharge it to 60%). The product will not be covered by the warranty if it is not charged or discharged for more than 6 months.
3. If the product has been idle for too long and the battery is severely low, it will enter a deep sleep protection mode. In such case, please charge the product before using it again.
