8. Do not stack any heavy objects on the product.
9.
Do not lock the fan forcibly during use or place the product in an unventilated or dusty area.
10. Ensure the product is not hit, dropped, or heavily vibrated. Securely fasten the product when transporting to avoid damage. If severely damaged, turn off the power source immediately and discontinue using the product.
11.
If you accidentally drop the product into water during use, please place it in a safe open area, and stay away from it until it is completely dry. The dried product should not be used again, and should be properly disposed of according to Section 2.2 below. If the product catches fire, we recommend that you use the fire extinguishers in the following order: water or water mist, sand, fire blanket, dry powder, and finally a carbon dioxide fire extinguisher.
12. Only clean the ports with a dry cloth.
13.
Place on a flat surface to keep the product from falling over. If the product is overturned and severely damaged, turn it off immediately, place the battery in an open area, keep it away from people and combustibles, and dispose of it in accordance with local laws and regulations
14.
Ensure that the product is kept out of reach of children and pets.
15. Store the product in a dry and ventilated place.
16. It is recommended to use moisture barrier bags in wet environments (for example, places by the sea or waterways) to prevent the product from getting soaked.

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 efficent power consumption state.
2.2 Disposal Guide
1. When possible, fully discharge the battery before disposing it. Because it contains hazardous chemicals, only dispose of the battery in designated recycling channels and never with ordinary trash. Consult your local laws on battery recycling and disposal.

Using 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.
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.
3.8 APP
The EcoFlow App gives users the ability to control and monitor EcoFlow power stations remotely.
Read the EcoFlow App user guide and access the download link here: https://ecoflow.com/pages/ecoflow-app
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.

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 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%.
