Privacy Policy
By using Eco Flow Products, Applications and Services, you consent to the Eco
Flow Term of Use and Privacy Policy, which you can access via the “About”
section of the “User” page on the Eco Flow App or on the official Eco Flow
website at https://ecoflow.com/pages/terms-of-use and https://ecoflow.com/pages/privacy-policy
X-Boost
To avoid operation failure due to overload protection, the X-Boost feature
will be automatically enabled when the total output exceeds the rated output
power, which enables the product to power high wattage appliances at the rated
output power.
X-Boost Tips:
- X-Boost is enabled by default; you can enable or disable it in the Eco Flow App.
- X-Boost is not available when the AC output is turned on in a recharging state (in bypass mode) and when X-Boost is disabled.
- X-Boost is not applicable for all electrical appliances; it’s incompatible with appliances with strict voltage requirements. Appliances with voltage protection (such as precise instruments) are not supported. X-Boost mode is more suitable for heating devices. Please conduct your own tests with your devices with X-Boost enabled.
Emergency Power Supply (EPS)
The product supports EPS. When you connect the grid power to the AC Input Port of the product through an AC Charging cable, you can power electrical devices through the AC Output Sockets (AC power will come from the grid and not 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 function, this function 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 only charge one device at a time and avoid using multiple ones at the same time to avoid overload protection. EcoFlow takes no responsibilities for any device failures or data losses caused by failures to follow instructions.
