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

Notes on X-boost

This product has X-Boost enabled by default. You can use the EcoFlow app to turn this function on or off. X-Boost is not available in the following situations: (1) the AC output is turned on in the charging state (in bypass mode) and (2) the X-Boost mode is turned off. X-Boost is more suitable for heating and electrical equipment, but not for all electrical appliances. Some electrical appliances equipped with voltage protection (such as precision instruments, etc.) are not suitable for X-Boost. To confirm whether the device is compatible with X-Boost, please refer to the actual test.
