Everything looks fine. The unit is on, the battery shows 40% or 60% or whatever it was when you left it. But whatever you plug in — phone charger, lamp, laptop — nothing happens. No power. Not even a flicker.

This is one of the most common complaints in portable power station forums, and the good news is that in the majority of cases it’s not a hardware failure. It’s one of several causes that are fixable in under five minutes once you know what to look for.

Before going further: if the unit is visibly damaged, swollen, making unusual sounds, or emitting any smell — stop immediately and contact the manufacturer. Everything below applies to units that appear physically normal.

Wrong article? If your unit has a completely blank screen and won’t respond at all, you’re looking for a different problem — see our guide on why a portable power station won’t turn on. This article is for units that power on normally but don’t deliver power to connected devices.

Start Here: 60-Second Check

Before anything else, run through these four checks. One of them resolves this for most people before they get to the causes below.

• AC outlets not working — Lamps, laptops, kitchen appliances, anything with a standard plug getting no power → Start at Cause 1
• USB ports not working — Phone won’t charge, tablet shows nothing, USB-C device not responding → Start at Cause 3
• DC / 12V ports not working — Car-style outlet or barrel port has no output → Start at Cause 2
• All ports dead, unit otherwise on — Screen is on, battery shows charge, but every single output is dead → Start at Cause 5

The single fastest check: Try a completely different device and a completely different cable. A bad cable or a device with a short can trip the protection and kill the port — and it looks identical to a port failure. If a second device on a different cable works, the first cable or device is the problem, not the power station.

Quick Reference: 7 Causes and Fixes

Cause 1 (Most Common): AC Output Button Not Pressed

This is responsible for more “my power station isn’t working” posts in forums than any other single cause — including on units people have owned for months. On every major portable power station brand, the AC inverter is not automatically on when the unit powers up. It requires a separate, deliberate button press.

The main power button turns the unit on. A separate AC button activates the inverter and enables the AC outlets. These are independent. The unit can be fully on, battery at 80%, and every AC outlet completely dead — because nobody pressed the AC button.

The same logic applies to DC and USB outputs. Most units have a separate DC/USB button. If both are off, nothing works at all despite the unit appearing operational.

Why does this happen to experienced users? The output buttons don’t stay pressed between sessions on most units. Some models have a “remember last state” setting in the app, but it’s not always the default, and firmware updates have been known to reset it. A user on the DIY Solar Power forum described their Jackery Explorer 1000 Plus shutting off the AC output on its own after a period of inactivity — the Energy Saving Mode had turned the port off silently with no notification.

The Fix — 10 Seconds:

1. Look at the front panel. Find the button labeled AC (sometimes just an outlet symbol). Check if its indicator light is on.
2. If the light is off — press the AC button. The inverter will activate, usually with an audible click or fan spin-up. Test your device.
3. Do the same for the DC/USB button if those ports are also dead. Both outputs may need to be enabled independently.
4. If you want outputs to stay on automatically: some units let you disable Energy Saving Mode. On Jackery units, hold the AC button and the main power button simultaneously for about 10 seconds until the Energy Saving Mode icon disappears from the screen. Check your model’s manual for the exact combination — it varies by model.

If the AC light is already on and the outlets still have no power, proceed to Cause 3 (ECO Mode) or Cause 4 (overload protection tripped).

Cause 2: DC / 12V Output Not Enabled

DC outputs — the cigarette-lighter-style 12V port and DC barrel ports — operate independently from AC outputs and often have their own enable button. If your 12V devices or DC-powered gear isn’t getting power, the fix is usually identical to Cause 1: the DC output just isn’t turned on.

On most EcoFlow, Bluetti, and Jackery units, there’s a dedicated DC button (or a combined DC/USB button). The label varies — look for “DC,” “12V,” or a car outlet symbol. Its indicator light tells you whether those ports are active.

The Fix:

1. Find the DC or DC/USB button on the front panel. Check the indicator light — if it’s off, press the button to enable the DC outputs.
2. Test your 12V device. If the port activates but the device still doesn’t work, swap cables and try a different device to rule out a cable or device fault.
3. Some units have user-replaceable DC fuses (check your manual). If the DC output button is on but the port has no power, a blown fuse is the next thing to check. Look for a small fuse holder near the DC port on the unit body.

Cause 3 (Very Common): ECO Mode Cutting Off Low-Draw Devices

ECO Mode — called different things by different brands but present on essentially all major units — automatically shuts off AC output when it detects a load below a certain wattage threshold for a period of time. The intent is to prevent the inverter from running continuously when you’ve forgotten to unplug a device.

The problem: many real devices draw low enough wattage to trigger this. A phone charger at idle draws 1–3W. A small LED lamp draws 5–10W. A CPAP machine in standby draws almost nothing. A laptop at 100% battery draws very little. ECO Mode sees these loads and decides no one is using the outlet — and silently kills the AC output.

From your perspective: you plugged something in, the AC output light is on, and nothing happens. No error, no beep. Just no power.

Real forum example: A user on the Cloudy Nights forum bought a Jackery Explorer 300 Plus for astronomy use. Charged it fully, came back a month later, battery still at 100% — but none of the power outputs worked. This is a documented pattern with ECO Mode combined with storage: the unit sat idle long enough for ECO Mode to shut down outputs, and the setting persisted even when the unit was restarted.

The Fix:

1. Quick test: plug in a higher-draw device — a hair dryer on low, a small fan, anything that pulls 50W or more. If that device gets power, ECO Mode is definitely the cause.
2. EcoFlow units: open the EcoFlow app → tap your device → go to Settings → find “ECO Mode” and toggle it off.
3. Bluetti units: in the Bluetti app, look for “ECO Mode” under device settings. On some models you can also toggle it by long-pressing the AC button on the unit itself — check your model’s manual for the exact hold duration.
4. Jackery units: Energy Saving Mode can be disabled by long-pressing the AC button and the main power button simultaneously for approximately 10 seconds until the Energy Saving icon disappears from the display. This varies by model — check your manual.
5. AllPowers and budget units: look for a long-press function on the AC button (hold 2–3 seconds) to force “Always On” mode.

Note for CPAP users: CPAP machines are a common ECO Mode trigger. The machine idles at very low draw until you breathe in — by which point ECO Mode may have already cut the port. Disable ECO Mode entirely if you’re using your power station for CPAP.

Cause 4: Overload Protection Tripped — Port Is Off, No Error Showing

When a connected device draws more power than the inverter can handle — especially motors that surge on startup (fridges, air compressors, power tools, window AC units) — the inverter’s overload protection trips and shuts the AC output off. On many units, this happens silently: no beep, no error code on screen. The AC button indicator stays lit, but nothing gets power.

This is distinct from an overload that is flagged with a beep or error code. If you’re seeing an error, that’s covered in our beeping guide. This cause is for the silent version — where the AC output simply stopped working at some point during or after a heavy load, and now nothing works even on low-draw devices.

The Fix — 2 Minutes:

1. Unplug every device from every output port — AC, DC, USB, everything.
2. Press the AC button to turn the AC output off (if the indicator is on). Wait 30 seconds.
3. Press the AC button again to turn the output back on. Test with a simple, low-draw device like a phone charger or a lamp.
4. If that doesn’t clear it, do a full power cycle: turn the unit completely off (long-press the main power button), wait 60 seconds, then power it back on and re-enable AC output.
5. Once output is restored, plug devices back in one at a time. If a specific device triggers the problem again, that device’s startup surge is exceeding your unit’s rated surge wattage.

If overload keeps happening with the same device: The issue isn’t the power station — it’s a mismatch between the device’s startup surge and the unit’s surge capacity. Appliances with motors (fridges, AC units, pumps) can pull 3–5× their running wattage for a fraction of a second on startup. A fridge rated at 150W running may pull 600–800W to start. Check your unit’s surge (peak) wattage spec, not just the continuous wattage. See our keeps turning off guide for more on the surge/overload dynamic.

Cause 5: Port Disabled in the App

EcoFlow and Bluetti units allow individual ports to be toggled on and off through the companion app. This is a useful feature — you can disable ports you’re not using to reduce phantom draw — but it also means a port can be off without any physical indicator showing it. The button light may be on, the unit appears active, but a specific port delivers nothing because someone (or a firmware update) switched it off in the app.

This is most commonly encountered with USB-C ports, which tend to have more granular app controls than AC outlets.

The Fix:

1. Open the EcoFlow or Bluetti app. Connect to your device via Bluetooth.
2. EcoFlow: on the main device screen, look for individual port toggles. Each AC outlet, USB-A port, USB-C port, and DC port has its own on/off control. Toggle the problem port off, wait a moment, then toggle it back on.
3. Bluetti: in the Bluetti app, go to the device settings screen and look for output controls. Confirm DC output is enabled if your DC ports are the issue.
4. If you can’t connect via Bluetooth, try a full power cycle first — that restores app connectivity in most cases.

Cause 6: Wrong Cable or Wrong Port Type

USB-C is where most of the cable confusion happens. Not all USB-C cables are the same, and the differences matter a lot for charging.

A USB-C cable that supports data transfer but not Power Delivery (PD) will charge a device at 5W — so slowly that the device may show “not charging” even though current is technically flowing. A cable rated for 15W can’t charge a laptop that needs 65W. The device will show nothing, or an error, or charge so slowly it appears dead.

Additionally, plugging a USB-C device into a USB-A port using a USB-A to USB-C cable will always limit output to whatever the USB-A port supports — usually 5V/2.4A (12W). For devices that expect USB-C PD charging at 45W or 65W, this looks like “not charging.”

The Fix:

1. Swap the cable with one you know works — ideally the cable that came with the device you’re trying to charge. If that works, the original cable is the problem.
2. For USB-C devices that need fast charging: plug directly into the USB-C port on your power station using a USB-C to USB-C cable rated for at least the wattage your device requires.
3. Check your power station’s USB-C output spec. Not all USB-C ports deliver the same wattage. On the EcoFlow DELTA 2, the two USB-C ports are rated differently from each other. Use the higher-wattage port for laptops and tablets.
4. If the port physically feels loose or the cable doesn’t click firmly into place, inspect the connector for bent pins or debris. A flashlight and a puff of compressed air resolves a surprising number of port issues. Never use metal objects to clean ports.

USB-C port failed entirely (Bluetti users): A confirmed issue on some Bluetti units — the AC180 specifically saw forum reports of USB-C ports dying within weeks of use, even with correct cables. Bluetti’s own support response in these cases was board replacement under warranty, not a user-serviceable fix. If the port works with zero devices and zero cables, contact support.

Cause 7: Inverter Fault or Internal Hardware Failure

If you’ve worked through everything above — output buttons are on, ECO Mode is off, no overload pending, app shows all ports enabled, cables are confirmed good — and the AC output still has nothing, the inverter itself may have failed.

This is less common than the software and settings causes, but it does happen. The pattern from forums is consistent: AC dead, USB and DC may still work, no error code shown, full power cycle and app reset don’t help. A Jackery 2000 Plus user described exactly this — the unit showed 44% charge, DC and USB operational, but AC output was 0W with no error. A technician confirmed inverter failure requiring warranty replacement.

A separate pattern: units stored for extended periods while fully charged (100%) can develop this issue. Extended storage at 100% stresses LiFePO4 cells. Some users report that after long storage at 100%, AC output stops working even though USB and DC ports are fine.

Last-Resort Reset Sequence:

1. Unplug all cables — AC charger, solar input, all output devices. Everything.
2. Long-press the main power button for 15 seconds. The screen should shut off completely. Release.
3. Wait 60 seconds with everything disconnected.
4. Plug the AC charger into the wall and connect to the unit. Wait 5 minutes for the BMS to stabilize.
5. Turn the unit on, enable AC output, and test with a simple device. If AC remains dead while USB and DC work, the inverter has failed.

When to contact the manufacturer:

• AC output dead after completing the full sequence above
• USB-C port completely non-functional with confirmed cables
• Error code on screen that doesn’t clear after power cycle
• Any physical damage, swelling, smell, or burn marks on the housing or outlets

When you contact support, have ready: your model name and serial number (on the bottom of the unit), purchase date, the ports that are dead versus working, and a summary of what you’ve already tried.

How to Prevent Output Problems

Frequently Asked Questions

My power station is on and shows battery charge, but nothing I plug in works. Where do I start? First check: is the AC button pressed and its indicator light on? On every major brand, AC output requires a separate button press from the main power button. If the indicator is on and still no power, check ECO Mode — low-draw devices commonly trigger auto-shutoff. Disable ECO Mode in the app, then test again.

AC ports work but USB doesn’t. What’s going on? AC and USB/DC are controlled independently. Check that the DC/USB output button is enabled (its indicator should be lit). If the button is on and USB still doesn’t work, swap cables first — a bad cable looks identical to a dead port. If a different cable and device both fail on that specific port, the port may have failed and needs manufacturer support.

Why does ECO Mode keep cutting off my device? ECO Mode shuts off AC output when the connected load drops below a threshold — typically somewhere between 5W and 30W depending on the brand and model. Phone chargers, small lamps, and idle CPAP machines often trigger this. Disable ECO Mode entirely if you need consistent power to low-draw devices.

The AC output tripped during use and now won’t reset. I’ve tried turning it off and on. Unplug everything — including the AC charger — and do a full power cycle: long-press the power button for 15 seconds until the screen goes dark, wait 60 seconds, then power back on. Re-enable AC output and test with a simple, low-draw device first. If the same heavy device trips it again, that device’s startup surge exceeds your unit’s rated peak wattage.

I stored my power station fully charged and now the AC doesn’t work. Is it broken? Possibly. Extended storage at 100% charge can stress LiFePO4 cells and trigger inverter protection states. Try the full reset sequence in Cause 7. If AC remains dead after that, contact the manufacturer — this is a warranty issue, not a user-fixable one. Going forward, store at 50–70% charge.

My USB-C port died after a few weeks of use. Can I fix it? If you’ve confirmed the port is truly dead with multiple known-good cables and devices, and the port physically looks undamaged, this is typically a board-level failure. Bluetti’s support response to this exact scenario on the AC180 was to issue a warranty replacement — it’s not user-serviceable. Contact the manufacturer with your purchase information.
