3.4 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 EcoFlow AC Cable for fast charging. EcoFlow takes no responsibilities for any consequences caused by failures to follow instructions, including but not limited to charging with third-party AC cables.

3.5 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.

3.6 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.

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 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.

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 https://ecoflow.com/pages/privacy-policy

3.9 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:

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.

3.10 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.

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. 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.

5. Troubleshooting

7. Storage & Maintenance

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%.
