How to Deal with Electromagnetic Interference

The use of communication equipment or equipment with electromagnetic interference, such as walkie-talkies and electromagnetic wave generators, will disrupt the power supply. You can use an extension cord to extend it slightly and use it at a longer distance.

DELTA Shut Down Unexpectedly

1. The battery is running out and needs recharging. 2. The default standby time of this product is 2 hours and can be set on the app. If the switches for the AC/DC outlets are not turned on and the product is not connected to any load, the product will automatically shut down after 2 hours. The default standby time can be set in the Ecoflow App.

Battery Runs Down Too Quickly

1. Please check if there are external high-power electrical appliances. If the power of the connected electrical appliance is about the same as the battery capacity, the battery will run out in about 1 hour. 2. Perform a complete charge and discharge for an SoC calibration.

DELTA Max Won't Charge

1. The charging temperature is too high. If you use high-power electrical appliances for a long time, stop using the unit until the temperature drops. 2. The charging temperature is too low. If the outside temperature is too low or the temperature of the battery cell is lower than 0°C, put DELTA Max somewhere warmer. 3. The charging voltage or current is too low. Charge the device according to the rated charging voltage and current. 4. Change the charging method or the cable when experiencing charging issues. Replace the cable or power source. 5. If none of the above methods work, provide a video showing the fault and contact support.eu@ecoflow.com

Output Overload Error

AC output overload: the AC icon will appear on the screen, and the ""Overload"" icon will flash: 1. Check whether the connected device's power meets the unit's power range. Connect a device with a wattage of 2400W-3000W to confirm that X-Boost is turned on in the app. If it's already turned on, connect to the app again. 2. In EPS mode, DELTA Max supports a maximum of 2200W. Confirm whether the electrical equipment is within this range. 3. The power of the electrical equipment is too large, causing it to fail to operate. DC output overload: the ""USB"" and ""Overload"" icons will flash together on the screen: 1. The output of the DC/car charger is overloaded. Check that the rated current of the device is under 8A. If the current is too high, it will cause overload, and the car charger may overheat. 2. The output of the DC-USB-Type C is overloaded. Confirm whether the electrical equipment is within the current limit of the outlet.
