General Product Usage

Product On, Product Off, LCD Screen On

Short press the Main Power Button to turn on the product; the LCD Screen will light up and the battery level indicator icon will display.
The product enters sleep mode after 5 minutes of idle operation; the LCD Screen will automatically turn off. When the product senses any load change or operations, the LCD Screen will automatically light up. To turn the LCD Screen on or off, please short press the Main Power Button.
To power off the product, press and hold the Main Power Button.
The default product standby time is 2 hours. With other Power Buttons turned off and no other load access for 2 hours, the product will automatically shut down. The standby time can be set on the App.

12V DC Output Port
With the Main Power Button turned on, short press the 12V DC Power Button to use the DC Output port. Short press the 12V DC Power Button again to turn it off. With the 12V DC Power Button on, the product will not automatically shut down.

AC Charging

EcoFlow's X-Stream fast charge technology is specifically for AC charging, offering 900W of Max input power. You can control the charging power through the AC Charge Speed Switch. When set to the top, you will have a charging speed of 900W. When set to the bottom it'll be at your custom speed, which is 200W 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 responsibilities for any consequences caused by failures to follow instructions, including but not limited to charging with AC charging Cable.

Solar Charging

Users can connect solar panels in series as shown in the figure to recharge the product.

*Solar charging cable (MC4-XT60 adapter cable) is supplied separately.
When using an EcoFlow solar panel to charge the product, please follow the instructions that come with the solar panel.
Before connecting the solar panel, please ensure that the solar panel's output voltage is within 75V to avoid product damages.

Car Charging

Users can recharge the product through the Car Charging Input Port. It supports 12V/24V car chargers and an 8A default charging current.
Please charge using the car charger after you've started the car to avoid failure to start due to insufficient car battery. In addition, please make sure that Car Charging Input Port and the Car Charging Cable are in good condition. EcoFlow takes no responsibilities for any losses or damages caused by failures to follow instructions.

APP

The EcoFlow App gives users the ability to control and monitor EcoFlow power stations remotely.

Privacy Policy
By using EcoFlow Products, Applications and Services, you consent to the EcoFlow Term of Use and Privacy Policy, which you can access via the "About" section of the "User" page on the EcoFlow App or on the official EcoFlow website at https://ecoflow.com/pages/terms-of-use and https://ecoflow.com/pages/privacy-policy.

X-Boost

With EcoFlow X-Boost technology, the product can power a 1800W Max device while the rated output power remains 1400W, avoiding operation failure due to overload protection.
Under standard voltage conditions, the total maximum output of all AC output ports is 1400W. With the X-Boost enabled, all AC output ports can power devices that require 1800W Max in total while the rated output power remains 1400W. The X-Boost will be automatically enabled when the total output of all output ports exceeds 1400W.

X-Boost Tips:

1. X-Boost is enabled by default; you can enable or disable it in the EcoFlow App.
2. 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.
3. 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. DO NOT use electric appliances with bare metal when charging to avoid the risk of electric leakage and electric shock. 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.

FAQS

What battery does the product use?

It uses high-quality lithium-ion battery.

What devices can the product's AC output port power?

With 1400W rated power and 2100W peak power, the product's AC output port can power most household appliances. Before you use it, we recommend that you confirm the power of the appliances first and ensure the power sum of all loaded appliances is lower than the rated power.
