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://www.ecoflow.com/policy/terms-of-use and
https://www.ecoflow.com/policy/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 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.
FAQS
-
What battery does the product use?
It uses high-quality LFP batteries. -
What devices can the product’s AC output port power?
With high-rated power and 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. -
How long can the product charge my devices?
The charging time is shown on the product’s LCD Screen, which can be used to estimate the charging time of most appliances with stable power usage. -
How can I know if the product is charging?
When it’s charging, the remaining charging time will be shown on the LCD Screen. Meanwhile, the charging indicator icon begins to rotate with the remaining battery percentage and the input power is shown on the right of the circle. -
How to clean the product?
Please gently wipe it with a dry, soft, clean cloth or paper towel. -
How to store the product?
Before storing, please turn off the product first, and then store it in a dry, ventilated place at room temperature. Do not place it near water sources. For long-term storage, please discharge the battery to 30% and recharge it to 60% every three months to extend its battery life. -
Can I bring the product on a plane?
No.
Troubleshooting
If the Alarm Prompt shows on the product LCD screen during use and does not
disappear after a restart, please stop using it immediately (do not try to

What’s In the Box
Storage & Maintenance
- Ideally, use and store the product between 20°C ~ 30°C (68°F ~ 86°F), and always keep it away from water, intense heat, and sharp objects. Do not store in temperatures above 45°C (113°F) or below -10°C (14°F) for an extended period.
- Storing a battery with a low charge for a long period shortens its lifespan. DELTA 2 mitigates the damage by putting the battery into hibernation mode. To get the most out of the battery, make sure it is about 60% before putting DELTA 2 into long-term storage, and then once every three months, discharge the battery to 30% and recharge it back to 60%.
