FAQ

DELTA Max Won't Charge From the Car Charger

1. Confirm that the 12V car charger has a standard voltage and power output. 2. Use another car charging cable to see whether the problem is with the standard car charging cable. Alternatively, use a solar panel to charge DELTA Max. If the solar panel works, the problem is with the car charger to XT60 cable. If the solar panel does not charge either, contact support.eu@ecoflow.com

The EF App Won't Connect to DELTA Max

1. Long press the IoT button under DELTA Max’s screen for 3 seconds until the WiFi icon flashes and the DELTA Max’s WiFi is turned on. 2. With the mobile phone near DELTA Max, search for the WiFi signal starting with """"EcoFlow"""" or """"DELTA Max"""" and follow the prompts to connect. 3. If you cannot find DELTA Max's signal, you can restart DELTA Max or try with another mobile phone. 4. If none of the above methods work, please provide the serial number photo at the bottom of the device and contact the support.eu@ecoflow.com

Cannot Find the Home WiFi

1. Press the IoT button again to reconnect. 2. Use another mobile phone to set up a hotspot connection. If the DELTA Max can connect to the phone's hotspot connection, it means that the connection function of the DELTA Max is normal. Since the WIFI connection only supports 2.4GHz, check the home router. If it is 2.4 GHz, modify the router configuration. 3. If none of the above methods work, provide a photo of the serial number at the bottom of the device and contact support.eu@ecoflow.com
