Description

The EcoFlow RIVER 2 Pro Power Station boasts a robust design with a durable outer casing, ensuring it withstands various environmental conditions. It features an intuitive LCD display that provides real-time information on battery level, output power, and charging status. The unit also includes multiple safety features such as overcharge protection, short-circuit protection, and thermal management to ensure safe operation.

The RIVER 2 Pro is highly portable due to its compact size and carry handle, making it easy to transport to camping sites or other off-grid locations. Its expandable capacity allows users to add an additional battery pack for extended power needs.

Power On/Off

Press the main power button once to turn on the product, then the LCD screen lights up and the main power indicator becomes breathing white; press and hold the main power button (for about 3 seconds) to turn off the product, meanwhile, the LCD screen also goes off.

After the product is turned on, press the main power button once to turn off the LCD screen.
If the product is not used for 5 minutes, it will enter hibernation state with the LCD screen gone off.
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)

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.
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

The solar charging cable (MC4-XT60 adapter cable) and the solar panel are supplied separately.
When using an EcoFlow solar panel to charge the product, connect them according to the instructions in the user manual.
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

NOTE: 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:

The X-Boost feature is not suitable for appliances with voltage protection (such as precise instruments).
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.

Setup Guide

To set up the EcoFlow RIVER 2 Pro Power Station, follow these steps:

Unbox the unit and inspect for any damage.
Charge the battery fully before first use using the provided AC charger.
Connect your devices to the appropriate output ports (AC, DC, USB).
If using solar panels, connect them to the DC input port.
Monitor the LCD display for status updates.

Do not disassemble or puncture this product in any way with sharp objects.
Do not block the fan forcibly during use.
Do not touch the product port with wires or other metal objects to avoid short circuit or other risks.
When using or transporting this product, please avoid shocks, drops and violent vibrations. In case of severe external shock, please stop using this product immediately and turn off the power.
Do not use unofficial components or accessories as this will void the warranty. Consult official EcoFlow channels if you need to replace any component or accessory.
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.
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.
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.
Do not put fingers or hands into the product.
To reduce risk of damage to the electric plug and cord, pull the plug rather than the cord when disconnecting the power pack.
Do not operate the power pack with a damaged cord or plug, or a damaged output cable.
To reduce the risk of electric shock, unplug the power pack form the outlet before attempting any instructed servicing.
Have servicing performed by a qualified repair person using only identical replacement parts. This will ensure that the safety of the product is maintained.
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.
Users not to place the product on the floor, or at a height less than 457 mm (18 inches) above the floor, during use in a repair facility.
For long-term storage, please discharge 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.
