EcoFlow does not provide free repair services for any damage to the power station caused by third-party products.

Entry-Level UPS

Entry-Level UPS RIVER Max Plus Entry-level UPS Use Reminder RIVER Max Plus’ X-Stream system supports an entry-level UPS function. You can use the RIVER Max Plus AC socket while the RIVER Max Plus is connected to an AC power source (your devices or appliances connected to the RIVER Max Plus AC socket will get power from the AC power source, not the RIVER Max Plus battery). When the AC power source loses power suddenly, the RIVER Max Plus will switch to provide power to the devices and appliances connected to it in <30ms. This is considered as an “entry-level” grade UPS function that does not support 0ms switching.
Do not connect devices with strict uninterrupted power supply requirements. Perform multiple tests to confirm compatibility before connecting devices such as data servers and workstations with RIVER Max Plus. EcoFlow will not be responsible for any loss of data or equipment damages caused by customers’ failure in following the instruction.
In accordance with the UL2743 standard, the AC outlets of the RIVER Max Plus are in a double blade, ungrounded configuration, it is recommended to use the UPS function only for temporary emergency usage rather than for long-term usage. DO NOT connect the RIVER Max Plus to devices or electrical appliances with bare metal when charging to avoid the risk of electric shock.

Entry-Level UPS User Guide
Users can connect the AC charging cable of RIVER Max Plus to an AC power source, connect a device to RIVER Max Plus, and turn on the AC switch to automatically enter the entry-level UPS mode. When the AC power source is cut off, power will be supplied from the battery of RIVER Max Plus to power your device (as shown below).*
UPS is only applicable to electrical appliances below 600W. To avoid an Overload condition, do not attempt to power any equipment drawing more than 600W of power. EcoFlow will not be responsible for any loss of data or equipment damages caused by careless use or customers’ failure to follow the instructions. Only one RIVER Max Plus can conduct the UPS function; the UPS function is not available when more than one RIVER Max Plus is connected together. Please follow the connection instructions below:

AC X-Boost Mode With the built-in 600W inverter, you can use the X-Boost feature to power 600W-1200W appliances without the disruption caused by overload protection. Traditional inverters will overload when one electrical appliance with a higher rated power is connected. Meanwhile, RIVER Max Plus’ built-in inverter, which has the X-Boost feature, enables the powering of 600W-1200W electrical appliances. Please take note of the following when using X-Boost:

The X-Boost mode is enabled by default. You can use the EcoFlow App to turn this function on/off.
The X-Boost mode is not available in the following situations: the charging state and X-Boost mode off state.
**When using appliances with a rated power of 600W-1200W, please connect only one appliance. When connecting more than one electrical appliance, the change of voltage may affect the usage of other electrical devices.***

* You may use electrical appliances with heating elements and a rated power between 600W-1200W, such as hairdryers and electric kettles. But the X-Boost mode is not applicable to all electrical devices. Some devices with a rated power of 600W-1200W that have strict voltage requirements are still not compatible. Please conduct a full test to confirm before usage. It is not recommended to use the RIVER Max Plus to charge heavy-duty devices, such as air conditioners, coffee machines, clothes dryers, electric camp stoves, full- size re- refrigerators, microwaves, mowers, ovens, washing machines, etc.
