X-Stream Fast Charging
1800W Max input Power
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 responsibilities for any consequences caused by failures to follow instructions, including but not
limited to charging with other AC charging cables.

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.
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.

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:
1. Turn off both the Smart Extra Battery and DELTA Pro
before connecting or disconnecting them.
2. Before using, make sure both DELTA Pro and Smart Extra
Battery display the extra battery icon on their screens.
3. Turn of the Smart Battery before connecting or
disconnecting it.
4. Do not touch the metal terminals of the Smart Extra
Battery connector. If the metal terminals need to be
cleaned, gently wipe them with a dry cloth.
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:
1. X-Boost is not available when the AC output is turned on in a recharging state (in bypass mode).
2. 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.

1. What battery does the product use?
It uses high-quality LFP battery.
2. What devices can the product’s AC output port power?
With 3600W rated power and 7200W 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.
3. 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.
4. 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
shown on the right of the circle.
5. How to clean the product?
Please gently wipe it with a dry, soft, clean cloth or paper towel.
6. 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.
7. Can I bring the product on a plane?
No.
4. FAQs
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.

1. 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 temperatures above 113°F or below 14°F for an
extended period.
2. 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%.
