When set to the top, you will have a charging speed of 400W. When set to the bottom it’ll be at your custom speed, which is 400W by default, customizable in the EcoFlow app. In case of unusual situations where the AC input current remains higher than 20A, the X-Stream charging input port will initiate a self-protection function, and the Overload Protection Switch on the product will automatically pop up. After confirming that there is no product failure, you can press the Overload Protection Switch to resume charging.
The charging power can be adjusted through the AC Charge Speed Switch on the
back of the product. You can set the charging power range in the EcoFlow App.
Please use AC charging Cable for fast charging. EcoFlow takes no
responsibility for any consequences caused by failures to follow instructions,
including but not limited to charging with AC charging Cable.

X-Boost
With EcoFlow X-Boost technology, the product can power a 3400W Max device
while the rated output power remains 2400W, avoiding operation failure due to
overload protection.
Under standard voltage conditions, the total maximum output of all AC
output ports is 2400W. With the X-Boost enabled, all AC output ports can power
devices that require 3400W Max in total while the rated output power remains
2400W. The X-Boost will be automatically enabled when the total output of all
output ports exceeds 2400W.
supports 3400W max devices while the rated output power is still 2400W.
X-Boost Tips:
- X-Boost is enabled by default; you can enable or disable it in the EcoFlow 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 responsibility for any device failures or data
losses caused by failures to follow instructions. The EPS of the product only
supports the following loads: below 1800W.
