Standard Manufacturers Warranty 

In this Warranty, the term products means all products manufactured by EcoFlow Technologies Inc. and supplied by EcoFlow Guam.

EcoFlow Guam warrants that the products will be of acceptable quality, free of latent defects, and will perform in accordance with the manufacturer’s specifications for the warranty period of 2-5 Years, with the exception of Solar products and accessories where the warranty period is 1 year. The warranty term commences on the date of product purchase (as per invoice/receipt). 

The EcoFlow Guam Warranty is valid for products purchased by consumers in Guam.

If a defect or fault covered by warranty occurs, EcoFlow Guam will, at its sole discretion, either: 

  • Repair the product 
  • Replace the defective components / product 
  • Provide a refund to the purchaser 

EcoFlow Guam reserves the right to replace the product or defective part of the product with a product or parts of similar or better quality or specification where an identical product or component is not available. products requiring repair may be replaced with refurbished components of the same type rather than being repaired. 

Any replaced products or components become the property of EcoFlow Guam. Replacement of the product or a part does not extend or restart the warranty term. This warranty covers the original purchaser only and is not transferable if the product is on-sold by the original purchaser. The sale by a party that is not an authorized reseller or distributor will be regarded as resupply and will result in the warranty being voided.  In particular, the sale of a product via an online auction, online store or other internet website by a party that is not an authorized distributor or reseller of the product will be deemed to be a resupply and will render this Warranty void, as EcoFlow Guam has no control over the storage, handling, quality or safety of products sold by such persons. 


A Purchaser shall only be entitled to the benefit of this Warranty after all amounts owing in respect of the product have been paid. While EcoFlow Guam warrants that the products will be free from defects in materials and workmanship in the circumstances set out in this Warranty, to the maximum extent permitted by law EcoFlow Guam does not warrant that the operation of the products will be uninterrupted or error-free. 

To the maximum extent permitted by law, the EcoFlow Guam determination of the existence of any defect and the cause of any defect will be conclusive. The agents, officers and employees of any distributor or reseller of the products and of EcoFlow Guam are not authorized to vary or extend the terms of this Warranty 

EcoFlow Guam shall not be responsible or liable to the Customer or any third party in connection with any non-performance or delay in performance of any terms and conditions of this Warranty, due to acts of God, war, riots, strikes, warlike conditions, plague or other epidemic, fire, flood, blizzard, hurricane, changes of public policies, terrorism and other events which are beyond the control of EcoFlow Guam. In such circumstances, EcoFlow Guam may suspend performance of this Warranty without liability for the period of the delay reasonably attributable to such causes. 

If a clause or part of a clause in this Warranty can be read in a way that makes it illegal, unenforceable or invalid, but can also be read in a way that makes it legal, enforceable and valid, it must be read in the latter way. If any clause or part of a clause in this Warranty is illegal, unenforceable or invalid, that clause or part is to be treated as removed from this Warranty, but the rest of this Warranty is not affected. Warranty service will be provided within Guam only.

  • A battery can deliver only a fixed number of usable cycles / amp-hours over its lifetime and is considered to have reached its normal end of life if the application uses up all of these cycles/ amp-hours, regardless of the time the battery has been in service. Therefore EcoFlow Guam reserves the right to deny a warranty claim if it determines the battery to be at its normal end of life, even if the claim is lodged within the applicable warranty period.
  • The battery is pre-programmed by Ecoflow to suit the battery configuration. Any changes that are made to the pre-configuration programming will void the warranty for the product
  • Batteries replaced under the warranty provisions will be shipped with a replacement warranty sticker and carry only the remainder of the original Applicable Warranty Period.
  • The battery has a self-discharge rate of approximately 2.5% per month @ 25°C. . It is the responsibility of the end user to maintain the battery in a charged state. The battery should not be left for more than 30 days without checking its charge state. EcoFlow GUam recommends that a battery left in a “storage state” should be checked and charged every 60 days to maintain maximum life expectancy of the battery. Failure to follow these requirements may see an early failure of the battery which is not covered under warranty.
  • Prolonged storage of the product in a fully discharged state will void the warranty.
  • Overcharging, undercharging, charging or connecting charging currents in reverse polarity will void the warranty.
  • Use of charging sources other than approved in the User Manual will void the warranty as they have not been tested. Non tested charging sources may not have programmable lithium profile configurations and charging voltages and could cause early failure of the battery.
