This product is not recommended for powering medical emergency equipment related to personal safety, including but not limited to medical grade ventilators (hospital CPAP: Continuous Positive Airway Pressure) or artificial lungs (ECMO: Extracorporeal Membrane Oxygenation). The product can be used to power a home ventilator (home CPAP) that 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 EcoFlow app when connecting the power supply product to ensure a 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, plug or 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 should not to place the product on the floor, or at a height less than 457 mm (18 inches) above the floor, when 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.

Disposal Guide

Whenever possible, please completely discharge the battery of this product before placing the product in the designated battery recycling bin. This product contains batteries. Batteries are hazardous chemicals and should not be disposed of in ordinary trash cans. For details, please follow local laws and regulations on battery recycling and disposal.
If the battery cannot be completely discharged due to the failure of the product itself, please do not dispose of the battery directly in the battery recycling bin, and contact a professional battery recycling company for further processing.
The battery will not start after over-discharge, please dispose of it.

Grounding Instructions

This product must be grounded. If it should malfunction or break down while charging, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with a power cord that has an equipment grounding conductor and a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes ordinances.
Improper connection of the equipment grounding conductor is able to result in a risk of electric shock. Check with a qualified electrician if you are in doubt as to whether the product is properly grounded. Do not modify the plug provided with the product – if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

Charge RIVER 2

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 30 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.
To avoid failure to start due to insufficient car battery, use the car charger after the vehicle is started. In addition, please make sure that the car charger cable is securely connected to the cigarette lighter.
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 600W 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-driven 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 power only one device (with maximum power <600W) at a time and avoid using multiple appliances 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

If a warning appears 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.
