AC Charging
EcoFlow’s X-Stream fast charge technology is specifically for AC charging, offering 1800W of max input power. You can control the charging power through the AC Charge Speed Switch. The default max input power for the AC charging speed is 400W, which can be modified 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 the AC Charging Cable included in the package for fast charging. Do
not use other cables to charge. Plug directly into an AC wall outlet and make
sure that the wall output current is more than 15A. Otherwise, reduce the unit
charging speed with the AC Charge Speed Switch. EcoFlow takes no
responsibility for any consequences caused by failures to follow instructions,
including but not limited to charging with other AC charging cables. 7
Solar Charging
Users can connect solar panels in series as shown in the figure to recharge
the product. The product supports 11-150V DC input, 15A max current, and 1600W
max charging power.
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 150V to avoid product damages.
Car Charging
Users can recharge the product through the Car Outlet. 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 the cigarette lighter of the Car Outlet and the Car Charger Input Cable are in good condition. EcoFlow takes no responsibilities for any losses or damages caused by failures to follow instructions.
**Using Smart Extra Battery
**
A single DELTA Pro can link with up to two Smart Extra Batteries at once for
added capacity. Refer to the user manuals of the Smart Extra Battery and Smart
Generator for detailed instructions.
Precautions:
- Turn off both the Smart Extra Battery and DELTA Pro before connecting or disconnecting them.
- Before using, make sure both DELTA Pro and Smart Extra Battery display the extra battery icon on their screens.
- Turn of the Smart Battery before connecting or disconnecting it.

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

X-Boost
With EcoFlow X-Boost technology, the product can power a 4500W Max device while the rated output power remains 3600W, avoiding operation failure due to overload protection.
X-Boost Tips:
- X-Boost is not available when the AC output is turned on in a recharging state (in bypass mode).
- X-Boost is not applicable for all electrical appliances; it’s incompatible with appliances with strict voltage requirements and a rated power over 3600W. 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 cable, you can power electrical devices through
the AC Output Port (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.

What’s In the Box
Storage & Maintenance
- Ideally, use and store the product between 68°F to 86°F, and always keep it away from water, intense heat, and sharp objects. Do not store in emperatures above 113°F or below 14°F for an extended period.
- Storing a battery with a low charge for a long period shortens its lifespan. DELTA Pro 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 Pro into long-term storage, and then once every three months, discharge the battery to 30% and recharge it back to 60%.
