Product Warranty
EcoFlow Product Warranty
Please note that the warranty period may vary according to local laws and regulations. Some countries, states, and provinces do not allow limitations on how long an implied warranty may last, so the limitation described above may not apply to you. You may have other rights from state to state, province, or country.
DO NOT USE YOUR PRODUCTS UNTIL YOU HAVE READ THE TERMS OF THE WARRANTY.
All EcoFlow products purchased come with a limited warranty. BY USING ECOFLOW PRODUCTS, YOU AGREE TO BE BOUND BY THE TERMS OF THE ECOFLOW LIMITED WARRANTY.
The warranty period started when the original purchaser received the products.
Warranty extension
You can extend the warranty for products purchased between January 1, 2022, and August 31, 2022, by registering on the official website on or before October 15, 2022.
Warranty cannot be extended for products purchased before January 1, 2022.
Customers who have purchased products on or after September 1, 2022 will enjoy the warranty period (with warranty extension) listed in the table above. Customers are advised to complete registration as early as possible.
Exclusions and Limitations
This warranty does not apply:
- Non-quality related issues;
- Items purchased from unauthorized resellers;
- Purchases without valid proof of purchase;
- Items that have been refunded;
- Items that have expired their warranty period;
- Any defects or damages caused by misuse of products, unauthorized modification, dis-assembly or operation not in accordance with the official instructions or manuals;
- Any defects or damages caused by exposure to excessive heat, liquids or other external causes;
- Any defects or damages caused by reliability or compatibility issues when using unauthorized third-party parts;
- Lost or stolen products;
- Free products.
Cross-Regional After-Sales Service
EcoFlow does not provide a global product warranty, and the warranty service can only be obtained at a designated EcoFlow repair center.
To repair the product in an EcoFlow repair center when the product was purchased in another region, depending on part availability, customers can obtain a cross-regional repair service at an additional charge. (Some products do not support cross-regional repair even if the customer is willing to pay for the service. For more details, please contact EcoFlow Support.)
A cross-regional replacement service is not available for different versions of the same product.
The customer will need to bear customs duties, taxes, customs clearance, and other costs incurred for a cross-regional repair, regardless of whether it is the warranty or paid repair service.
Valid Proof of Purchase
- A purchase order number made through ecoflow.com;
- Sales invoice or order confirmation email that clearly shows the description of the product, its price, and sales channel.
Warranty Registration
- Register your warranty at https://www.ecoflow.com/us/support/warranty
Return Material Authorization (RMA) process
- Contact EcoFlow Customer Service Team at support@ecoflow.com or +1 (800)-368-8604 (this number supports English service only. International charges apply if calling from outside of the US).
- If your item is eligible for an EcoFlow Warranty, you will receive a prepaid shipping label. Please follow the instructions provided by EcoFlow Support to properly pack the products and return them safely.
- Please note that we can only provide return shipping labels for return packages in United States. For returns in other countries and areas, please contact EcoFlow Support at support@ecoflow.com for more details.
Replacement
- In case of replacement, delivery of the replacement item will be arranged within 15 business days (subject to changes caused by force majeure) after confirming that the defective item has been received at our warehouse. The final resolution is subject to the availability of the replacement items.
- The replacement warranty will be covered by a period equal to the remaining warranty period of the original item.
Product FAQs
When using instruments to measure the AC power output, why are the L and N measurements reversed?
The portable power station is a floating-ground system, meaning that this type of detection equipment is likely to be ineffective. The detection equipment is designed to detect grounded output from grid power. The voltage difference between neutral and ground in the grid is very small, which is why there is a distinction between positive and reverse wiring. The device's AC output is generated by boosting the internal battery voltage through an inverter. Since there is no reference ground, testers may indicate reversed wiring. Furthermore, in the portable power station, both L and N are energized. When operating in inverter-only mode, the two wires can be regarded as equivalent, so the concept of reversed wiring does not apply. Think of it like this: AC voltage follows a sine wave pattern and its direction changes. As a result, the electric potential of L and N change relative to each other. On a microscopic timescale, current flows from high potential to low potential. However, since AC operates at 50 Hz, with 50 direction change cycles per second, the frequency is too high to distinguish. On a macroscopic level, the two wires appear the same during inversion. Many instruments will show the same peak voltage for both wires, so they can be regarded as equivalent with no distinction.
Does the Delta 3 Ultra or Delta 3 Ultra Plus support UPS-HID, and how does it establish communication with electronic devices?
Support. 1. Make sure the device (e.g., NAS device, PC, or laptop) supports UPS functionality. 2. Use a data cable to connect the USB-C-140W output port of the portable power station to the USB port of the device (supports USB 2.0 protocol). 3. After the connection is successful, go to the settings page for the device (e.g., NAS) and adjust the relevant settings.
What should I do if the device won't turn on?
1. Long-press the power supply button for at least 3 seconds to check whether the display turns on. 2. Connect an input to charge the device and check whether there is input power. If there is no response after 10 minutes, contact the after-sales team for assistance.
How much does DELTA 3 Ultra or DELTA 3 Ultra Plus weigh?
The DELTA 3 Max main unit weighs approximately 32.7kg The DELTA 3 Max main unit weighs approximately 33.7kg.
