EcoFlow “Overload” Error: 3 Ways to Fix It (Delta 2 & River 2 Guide)

Intro: You plugged in your coffee maker, heard a click, and now your EcoFlow screen says “OVERLOAD” with a red icon. Did you break it? Probably not. EcoFlow units are sensitive to “Surge Power,” and a hidden setting called X-Boost is often the culprit. Here is how to clear the error and prevent it from coming back. f your unit is faulty, check out our Anker vs EcoFlow Comparison to see if switching brands is right for you.

Step 1: The Physical Reset (Do This First)

Before messing with the app, clear the immediate error.

1. Unplug Everything: Remove all cables from the AC outlets.
2. The “Pop-Out” Button: On older models (Delta 1300), check the side for a physical “Overload Protection” switch that popped out. Push it back in.
3. The Power Cycle: On newer models (Delta 2 / River 2), turn the AC Power Button OFF, wait 10 seconds, and turn it back ON.

Step 2: The “X-Boost” Trap (The #1 Cause)

EcoFlow’s “X-Boost” feature lowers the voltage to run high-wattage devices.

• The Problem: Some devices (like Nespresso machines or microwaves with digital screens) hate low voltage. They detect “bad power” and trip the EcoFlow’s safety sensor.
• The Fix:
  1. Open the EcoFlow App.
  2. Go to Settings > AC Settings.
  3. Toggle OFF “X-Boost”.
  4. Try the appliance again.

Step 3: The “Starting Watts” Reality Check

If X-Boost is off and it still fails, you are likely exceeding the Surge Limit.

• Example: A 1500W air compressor might need 3000W for 0.5 seconds to start.
• The Check: Look at the “Surge” rating in your manual.
  • Delta 2: 2700W Surge.
  • River 2 Pro: 1600W Surge.
  • Solution: You need a bigger battery.

Pro Tip: If you frequently hit “Overload,” your battery is too small for your needs. Check our guide on How Long a 1000Wh Battery Runs Appliances to size your next unit correctly.
