Product Warranty

EcoFlow Product Warranty

DO NOT USE YOUR PRODUCTS UNTIL YOU HAVE READ THE TERMS OF THE WARRANTY.

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.

  • 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.

Product FAQs


What are the warranty policies for DELTA 3 Max or DELTA 3 Max Plus?

The device has a 3-year basic warranty, which can be extended by 2 years if you register on the app.

How many decibels of noise does the device generate during normal use?

When within 1.64 feet of the device, the noise generated is less than 30 dB during 600W consumption and less than 38 dB during 1200W consumption. 30 dB is about the same volume as quiet whispering, or the environmental noise level of a quiet library or office. Most people find 30 dB to be a comfortable level of background noise.

How do I enable the X-Boost feature?

This feature is enabled by default. It can be enabled or disabled in the EcoFlow app.

Does the device support Bypass Mode output?

Yes, Bypass Mode output is supported, and it is enabled by default. It can also be disabled in the app. If the grid power is unstable and may cause improper functioning or damage to appliances, you can enable this setting in the EcoFlow app for appliances that require high-quality power output. For example, this mode allows you to use only the AC output power from the portable power station for speakers.

Are DELTA 3 Max and DELTA 3 Max Plus uninterruptible power supplies (UPS), and what's the switchover time in milliseconds?

DELTA 3 Max and DELTA 3 Max Plus are UPSs with a switch time of less than 10 ms, but DELTA 3 Max does not support UPS-HID functionality.
