3.3 General Product Usage

Product On, Product Off, LCD Screen On: Short press the Main Power Button to turn on the product; the LCD Screen lights up and displays the battery level indicator. The product enters sleep mode after 5 minutes of idle operation, turning off the LCD Screen. The LCD Screen automatically lights up upon sensing load changes or operations. Short press the Main Power Button to turn the LCD Screen on or off. Press and hold the Main Power Button to power off the product. Default standby time is 2 hours; the product shuts down automatically after 2 hours of inactivity with other power buttons off and no load. Standby time can be set on the APP.

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

AC Output Port: With the Main Power Button on, short press the AC Power Button to use the AC Output ports. Short press again to turn it off. The default standby time for the AC Output port is 12 hours. The AC Power automatically turns off after 12 hours of no load access. Turn off the AC power button when not in use to save power consumption.

3.4 AC Charging

X-Stream Fast Charging: EcoFlow's X-Stream fast charge technology offers 1800W max input power for AC charging. Charging power can be controlled via the AC Charge Speed Switch. The default max input power is 400W, adjustable in the EcoFlow app. In cases of AC input current exceeding 20A, the X-Stream charging input port initiates self-protection, and the Overload Protection Switch pops up. Press the switch to resume charging after confirming no product failure.

Diagrams illustrate the AC charging process: one shows the AC Charging Cable connecting to the X-Stream AC Charging Input Port, indicating X-Stream Fast Charging with 1800W Max input Power and an approximate 2.7 hrs Full Charge time. Another diagram shows the AC Charge Speed Switch and mentions the EcoFlow App for Customized Charging Power Rate (Range: 200-1800W, Default: 400W).

Charging Instructions: Charging power can be adjusted via the AC Charge Speed Switch. Use the included AC Charging Cable. Plug directly into an AC wall outlet with an output current greater than 15A. If not, reduce the unit's charging speed using the AC Charge Speed Switch. EcoFlow is not responsible for consequences due to failure to follow instructions, including charging with other AC cables.

3.5 Solar Charging

Solar Charging: Connect solar panels in series to recharge the product. Supports 11-150V DC input, 15A max current, and 1600W max charging power.

Diagram shows a Solar Panel connected via Solar Charging Cable (MC4 connectors) to the Solar/Car Charging Input Port.

Important Note: When using an EcoFlow solar panel, follow its instructions. Ensure the solar panel's output voltage is within 150V before connecting to avoid product damage.

3.6 Car Charging

Car Charging: Recharge via the Car Outlet. Supports 12V/24V car chargers and an 8A default charging current.

Usage Recommendation: Charge using the car charger after starting the car to prevent insufficient car battery. Ensure the cigarette lighter of the Car Outlet and the Car Charger Input Cable are in good condition. EcoFlow is not responsible for losses or damages caused by failures to follow instructions.

Diagram shows a Car Charging Cable connecting to the Car Outlet.

3.7 Using Smart Extra Battery

Capacity Expansion: A single DELTA Pro can link with up to two Smart Extra Batteries for increased capacity. Refer to the respective user manuals for detailed instructions.

Precautions:

1. Turn off both the Smart Extra Battery and DELTA Pro before connecting or disconnecting.
2. Ensure both DELTA Pro and Smart Extra Battery display the extra battery icon on their screens before use.
3. Turn off the Smart Battery before connecting or disconnecting it.
4. Do not touch the metal terminals of the Smart Extra Battery connector. Clean terminals gently with a dry cloth if needed.

Privacy Policy: By using EcoFlow Products, Applications, and Services, you consent to the EcoFlow Term of Use and Privacy Policy.

3.9 X-Boost

Enhanced Output: EcoFlow X-Boost technology enables the product to power a 4500W Max device while maintaining a rated output power of 3600W, preventing overload protection failures.

X-Boost Tips:

1. X-Boost is unavailable when AC output is on during recharging (bypass mode).
2. X-Boost is not compatible with all appliances, especially those with strict voltage requirements or rated power over 3600W. Appliances with voltage protection (e.g., precise instruments) are not supported. X-Boost mode is best suited for heating devices. Test with your devices before enabling X-Boost.

3.10 Emergency Power Supply (EPS)

UPS Functionality: The product supports EPS. Connecting grid power to the AC Input Port allows devices to be powered via the AC Output Port (using grid power). In case of a blackout, the product switches to battery power within 30ms. This basic UPS function does not support 0ms switching. Do not connect devices requiring 0ms UPS, such as data servers or workstations. Test compatibility before use. It is recommended to charge one device at a time to avoid overload protection. EcoFlow is not responsible for device failures or data losses due to improper use.

Diagrams illustrate the EPS mode: one shows an AC cable from the wall connected to the AC Input Port, and devices connected to the AC Output Port. Another diagram shows a computer monitor connected to the product.

4. FAQs

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. Confirm the power of your appliances and ensure the total power sum is lower than the rated power before use.

3. How long can the product charge my devices?

The charging time is shown on the product's LCD Screen, which can estimate the charging time for most appliances with stable power usage.

4. How can I know if the product is charging?

When charging, the remaining charging time is displayed on the LCD Screen. The charging indicator icon rotates with the remaining battery percentage and input power.

5. How to clean the product?

Gently wipe with a dry, soft, clean cloth or paper towel.

6. How to store the product?

Before storing, turn off the product and store it in a dry, ventilated place at room temperature, away from water sources. For long-term storage, discharge the battery to 30% and recharge to 60% every three months to extend battery life.

7. Can I bring the product on a plane?

No.

5. Troubleshooting

Important Note: If the Alarm Prompt remains on the product LCD screen during use and does not disappear after a restart, stop using the product immediately (do not try to charge or discharge). For any other assistance, please contact EcoFlow Customer Service.

7. Storage & Maintenance

1. Ideally, use and store the product between 68°F to 86°F, away from water, intense heat, and sharp objects. Avoid storing in temperatures above 113°F or below 14°F for extended periods.
2. Storing a battery with a low charge for a long period shortens its lifespan. DELTA Pro mitigates this by entering hibernation mode. To maximize battery life, ensure the charge is about 60% before long-term storage. Every three months, discharge the battery to 30% and recharge it to 60%.
