Power station shuts off or says overload? Why and how to fix it

Try these first

1. Turn off the AC output and unplug everything.
2. Wait at least 30 seconds. EcoFlow says this lets the inverter cool and reset.
3. Check the battery percentage on the screen.
4. Plug in the lowest-wattage device first, then add others one at a time.
5. If one appliance trips it every time, read its label. It may need more watts than the station can give.
6. Give the unit space so its fans can breathe.

Too much load

Symptom: The AC output cuts off, and the screen may show an overload warning.

Why it happens: Jackery explains that overload means running beyond the rated power. It triggers the overload protection and, in severe cases, can cause overheating and damage. EcoFlow says the inverter shuts down when the load goes over its continuous rating or its surge capacity. Jackery also says a device's power must be at or below the station's rated power, ideally with some margin.

How to check and fix it:

1. Add up the watts of everything plugged in. If a label lists amps, multiply by 120 for a US outlet.
2. Compare the total with the station's rated (continuous) output, not its peak.
3. EcoFlow suggests keeping the continuous load at least 20 to 30% below the AC rating.
4. Run high-draw items like kettles, hair dryers and space heaters one at a time.

A motor's startup surge

Symptom: It works for small things, but shuts off the moment a fridge, pump, compressor or power tool starts.

Why it happens: Motors and compressors need a big burst of power to start. Jackery calls these inductive loads. It gives an example of a fridge rated at 50W that may need up to 350W, 7 times its rating, for a moment at startup. EcoFlow says motors and heating elements may need 2 to 4 times their running watts at startup. If that burst goes over the station's peak rating, it shuts off.

How to check and fix it:

1. Find the station's peak or surge rating in the manual.
2. Unplug everything else, then start the motor on its own.
3. If it still trips with nothing else plugged in, the appliance's startup surge is too big for this unit.
4. See can a power station run a refrigerator for how fridge surge and runtime work.

It's overheating

Symptom: It runs a heavy load for a while, then cuts out, often in a hot room or in the sun.

Why it happens: EcoFlow says the inverter shuts down to prevent overheating and circuit stress. Heavy loads make heat, and so does a hot room.

How to check and fix it:

1. Turn off the output and let it cool.
2. Move it out of direct sun, and away from walls and covers so the vents can breathe.
3. Restart with a smaller load.

The battery is low

Symptom: It shuts off after running normally for a while.

Why it happens: Jackery says that when the battery is low or empty, the station automatically shuts off output.

How to check and fix it: Check the battery percentage. Recharge it, then try again.

Auto-off with a small load

Symptom: A phone, earbuds or a small light stops charging after a while. Or the whole unit turns itself off when little is plugged in.

Why it happens: Many units switch off outputs that seem idle, to save battery. Jackery says its USB ports have low-load detection, and turn off automatically for devices drawing under about 2W, like Bluetooth earbuds and smart bands. It says this is normal. Some models also have an automatic shutdown timer. On Jackery's app-connected Pro and Plus models, you can turn it on or off in the app.

How to check and fix it:

1. Open the maker's app or settings menu. Look for auto-off, standby or screen-timeout settings.
2. Extend the timer or turn it off for the output you need.
3. For tiny devices, restart the output when it stops. That's expected behavior.

A fault in the port or the unit

Symptom: One output never works, even with a small, known-good device.

Why it happens: Jackery says that if the battery has charge, the output light is on, and the device's watts are within the rating but it still doesn't work, it may be an internal fault.

How to check and fix it: Try a different device and a different port. If the port still doesn't work, contact support.

When to stop and call a pro

Stop using it and contact the maker if you notice:

• Swelling, bulging or leaking
• Smoke, a burning smell or severe overheating
• Melted or scorched ports
• Repeated error codes or temperature warnings

Anker lists these as signs to stop using the unit right away, and says not to open the battery enclosure yourself. Opening it risks a lithium battery fire and will likely void the warranty. Have your model, serial number and any error codes ready.

Never plug a power station into a wall outlet to power your house circuits.
