Following this, place the product in a safe, waterproof and open area. Once complete contact EcoFlow Customer Service immediately.

17. This product is not recommended for powering medical emergency equipment related to personal safety, including but not limited to medical grade ventilators (hospital version CPAP: Continuous Positive Airway Pressure), artificial lungs (ECMO, Extracorporeal Membrane Please follow your doctor's instructions and consult with the manufacturer for restrictions on the use of the equipment. If used for general medical equipment, please be sure to monitor the power status to ensure that the power does not run out.

18. When in use, power supply products will generate electromagnetic fields, which are likely to affect the normal operation of medical implants or personal medical equipment such as pacemakers, cochlear implants, hearing aids, defibrillators etc. If these types of medical equipment are being used, please contact the manufacturer to inquire about any restrictions on the use of such equipment. These measure are fundamental to ensure a safe distance between the medical implants (for example, pacemakers, cochlear implants, hearing aids, defibrillators etc.) and this product while in use.

19. When the power supply is connected in normal mode to a refrigerator, power fluctuations may cause the power supply to automatically shut down. When connecting the power supply to a refrigerator that stores medicine, vaccines or other valuable items, it is recommended to set the AC output to "Always on" in the app. This helps support a continuous power supply and ensures a safe and efficient power consumption state.

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://www.ecoflow.com/policy/terms-of-use and https://www.ecoflow.com/policy/privacy-policy

3.9 X-Boost

To avoid operation failure due to overload protection, the X-Boost feature will be automatically enabled when the total output exceeds the rated output power, which enables the product to power high wattage appliances at the rated output power.

X-Boost Tips:

1. X-Boost is enabled by default; you can enable or disable it in the EcoFlow App.
2. X-Boost is not available when the AC output is turned on in a recharging state (in bypass mode) and when X-Boost is disabled.
3. X-Boost is not applicable for all electrical appliances; it's incompatible with appliances with strict voltage requirements. 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 Charging cable, you can power electrical devices through the AC Output Sockets (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 takes no responsibilities for any device failures or data losses caused by failures to follow instructions.

7. Storage & Maintenance

1. Ideally, use and store the product between 20^ C \~ 30^ C ( 68^ F \~ 86^ F), and always keep it away from water, intense heat, and sharp objects. Do not store in temperatures above 45^ C ( 113^ F) or below -10^ C ( 14^ F) for an extended period.
2. Storing a battery with a low charge for a long period shortens its lifespan. DELTA 2 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 2 into long-term storage, and then once every three months, discharge the battery to 30% and recharge it back to 60% .
