Charging DELTA Pro

AC Charging

EcoFlow's X-Stream fast charging technology is specifically for AC charging, offering 1800W of max input power. You can control the charging power through the AC charging 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. Aputure takes no responsibilities for any consequences caused by failures to follow instructions, including but not limited to charging with other AC charging cables.

Solar Charging

1. Solar charging cable (MC4-XT60 adapter cable) and the solar panel are supplied separately.
2. When using an EcoFlow solar panel to charge the product, please follow the instructions that come with the solar panel.
3. 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.

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.

Illustration of two electric vehicle charging stations, one connected to a battery and the other with a logo (no text or symbols on the devices themselves)

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 off 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.

X-Boost and EPS

X-Boost

With EcoFlow X-Boost technology, the product can power a 4,500W max. device while the rated output power remains 3,600W, 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.

Bypass mode: When the product is plugged into the power socket for recharging and connected to other devices at the same time, it cannot provide power to the devices if the AC power button is turned on, instead, the devices are powered by the grid.

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 Oms switching. Please do not connect the product to any device that requires Oms 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 and Aputure take no responsibilities for any device failures or data losses caused by failures to follow instructions.
