EcoFlow is well known for its portable power stations and home battery backup options, with many of its products earning spots on our best lists. Unfortunately, not every product is a hit and EcoFlow has issued a voluntary recall for approximately 25,030 units of its EcoFlow Delta Max 2000 portable power stations (model EFD310) in cooperation with the US Consumer Product Safety Commission (CPSC) due to the risk of a fire hazard. This isn't a power station we've tested or recommended in the past, but it is one of the company's larger capacity models, allowing you to power a wide range of devices.
The good news is that the recall doesn’t require you to return your power station. The issue can be fully resolved through a firmware update that you can do yourself.
Here’s how to do it.
What’s the problem?
According to the CPSC, the Delta Max 2000 power station may overheat and ignite, posing a serious risk of burn injury and fire hazard to users and property. EcoFlow has received six reports of the power stations catching fire, resulting in property damage totaling over $850,000.
What portable power stations are affected?
The affected units were sold for about $1,600 on Costco.com, Amazon.com and Ecoflow.com from July 2022 through May 2025. The affected model number, EFD310, is printed on the nameplate on the underside of the product. If you’re unsure about the model, you can email EcoFlow’s customer service email ([email protected]) and provide pictures of the power station and they’ll help you confirm. No other models are affected by the recall.
What you should do if you own an EcoFlow Delta Max 2000
If you own an EcoFlow Delta Max 2000 (Model EFD310), you should stop using the power station immediately until the required firmware update is successfully installed. The fix is a simple, over-the-air update through the official EcoFlow app, which takes about 5 minutes to complete.
You can connect to the power station in the EcoFlow app to upgrade its firmware. EcoFlow
Follow these steps to update your device:
Power down and stop using the Delta Max 2000 (Model EFD310). Download the official EcoFlow app from the App Store or Google Play Store if you don’t already have it installed. Open the app, log in or sign up and connect your Delta Max unit using either IOT mode or Direct Connection mode. Locate your Delta Max in the device list and verify that the serial number displayed in the app matches the number engraved on the product’s base plate. Select the device to open its details page, tap the circle icon in the upper-right corner to enter the device settings page and select Firmware Upgrade under "Other Settings." Tap “Firmware Version Upgrade" and wait for it to reach 100%. Don’t use the power station during this time. The upgrade is successful when the firmware version shows 1.6.2.81.
EcoFlow has provided detailed instructions for how to upgrade the firmware. The process shouldn't take more than 5 minutes. EcoFlow
