ECO mode is one of the most useful — and most misunderstood — features on portable power stations. When used right, it can add hours of runtime by eliminating wasteful vampire drain. But when it catches you off guard (shutting off your CPAP in the middle of the night, for example), it feels like a bug, not a feature. This guide explains exactly how ECO mode works, how much battery it saves, when to use it, and how to fine-tune or disable it.
ECO mode (Economy mode) is a power-saving feature that automatically turns off output ports when the connected device draws very little power for a long period. It works by continuously monitoring how much power is being drawn from each output. If the load stays below a threshold (usually 10-50W) for a set duration (1-12 hours), ECO mode shuts down that output to prevent wasting battery on standby loads. The goal is to save battery by eliminating "vampire drain" — the small amount of power devices use even when they are "off."

ECO mode is surprisingly simple in concept but has subtle behavior that varies by brand. Here is the step-by-step process:
The power station's microcontroller measures the output power draw many times per second. It tracks how many watts are being pulled from each output port (AC, USB, DC).
It compares the measured power draw to the ECO threshold (default is typically 10-50W). If the load is below the threshold, a timer starts counting.
If the load stays below the threshold continuously for the timeout duration (1-12 hours, depending on settings), the ECO mode condition is met. If the load rises above the threshold at any point, the timer resets.
When the timer expires, the power station turns off that output (AC, USB, or DC, depending on which one had the low load). On many units, you will hear a single beep when ECO mode shuts off an output.
On most mid-range and premium power stations, ECO mode works independently per output type:
This means you can have a refrigerator running on AC (high load, no ECO shutdown) while a USB trickle-charging phone gets shut off by ECO mode. On budget models, ECO mode may be global — any load above the threshold keeps all outputs on, and if total load drops below threshold, everything shuts off.
The savings from ECO mode depend entirely on what you are powering and how much vampire drain your devices have. Here are real-world examples:
| Scenario | Without ECO | With ECO | Savings |
|---|---|---|---|
| TV in standby all day | 15W × 24h = 360Wh | 0Wh (shuts off after timeout) | 360Wh saved |
| Phone charger left plugged in | 3W × 24h = 72Wh | 0Wh (shuts off after timeout) | 72Wh saved |
| Game console on standby | 10W × 24h = 240Wh | 0Wh (shuts off after timeout) | 240Wh saved |
| Camping (intermittent use) | 50W average (including idle) | 40W average (ECO cuts idle) | ~20% more runtime |
| Constant full load (fridge) | 100W continuous | 100W continuous (no change) | 0% savings |
The general rule: ECO mode saves 5-20% of total battery capacity for typical mixed use. The more standby/idle loads you have, the more ECO mode saves. If you are running devices continuously at high power (like a refrigerator), ECO mode does nothing because the load never drops below the threshold.
Biggest savings scenario: Backup power during an outage where you use devices intermittently (turn lights on at night, use the fridge occasionally, charge phones a couple times a day). ECO mode ensures that when you are not actively using something, the power station is not wasting battery on standby drains.
The exact way to turn off ECO mode depends on your power station brand and model. Here are the most common methods:
| Brand | How to Disable ECO Mode | Adjustable Threshold? | Adjustable Timeout? |
|---|---|---|---|
| EcoFlow | App: Settings → Eco Mode → Toggle off, or press ECO button on unit | Yes (app) | Yes (app) |
| Jackery | Press ECO/Power Saving button on unit (some models), or app settings | Limited (some models) | Limited (some models) |
| Bluetti | Touchscreen: Settings → ECO Mode → Off, or Bluetti app | Yes (app/screen) | Yes (app/screen) |
| Anker | Anker app: Settings → Power Saving → Disable | Yes (newer models) | Yes (newer models) |
| Goal Zero | Yeti app: Settings → Low Power Shutoff → Disable | Yes | Yes |
Pro tip: Before fully disabling ECO mode, try raising the threshold instead. If your CPAP draws 15W and the threshold is at 10W, raising it to 25W stops the CPAP from triggering ECO while still saving power from true vampire drains like TVs on standby. Most premium stations let you customize this in the app.
Every brand implements ECO mode slightly differently. Here is how they compare:
EcoFlow has one of the most customizable ECO implementations. You can set the threshold and timeout independently for AC, USB, and DC outputs in the EcoFlow app. The Delta series even lets you set per-outlet ECO settings on some models.
Default threshold: ~10W AC, lower for USB. Default timeout: 1-4 hours depending on model.
Jackery calls it Power Saving Mode. On most Explorer models, it is controlled by a physical ECO button. Customization is limited — some models only have on/off with a fixed 8-hour timeout. Newer Explorer Pro+ models add app-based customization.
Default threshold: ~10-20W. Default timeout: 8 hours (fixed on many models).
Bluetti's ECO mode is configurable via the touchscreen and app. You can adjust both threshold and timeout. Bluetti tends to have a higher default threshold (~20-50W) compared to competitors, which means it is more aggressive about shutting things off.
Default threshold: ~20-50W (varies by output). Default timeout: 1-12 hours configurable.
Anker's Power Saving Mode is app-controlled on 535 and 757 models. The 521 (budget model) has a more basic implementation. Anker tends to be conservative — their ECO threshold is on the lower end, so it is less likely to turn off devices you want running.
Default threshold: ~10W. Default timeout: 4 hours (some fixed).
This is the #1 complaint about ECO mode: people use their power station for CPAP while camping, and ECO mode shuts it off in the middle of the night because the CPAP's low-pressure draw falls below the threshold. Here is how to fix it:
The simplest and most reliable fix. Turn off ECO mode entirely for the duration of your CPAP use. You can always turn it back on during the day for other devices. This is the recommended solution for medical devices — do not risk it.
If your unit supports customizable ECO settings, raise the threshold above what your CPAP draws. If your CPAP uses 15W on low pressure, set the threshold to 25W. This way, the CPAP never triggers ECO shutdown, but true vampire drains (5W phone chargers, etc.) still get cut.
If you cannot disable or adjust ECO mode (budget units), add a small resistive load in parallel with your CPAP to keep the total draw above the threshold. A 15W incandescent light bulb or a 10W USB heater works. It wastes some power (the bulb's wattage) but prevents shutdowns. Calculate: if threshold is 20W and your CPAP is 12W, you need 8W+ of additional load.
Some units have different ECO thresholds for different outputs. USB usually has a lower threshold than AC. If your CPAP can run from DC (12V car port), try the DC output — it may have a lower ECO threshold or no ECO at all on some models. Check your manual for per-output ECO behavior.
Safety note for medical devices: Always test your setup before relying on it. Run a full night's test at home where you can monitor it. Verify that ECO mode does not interfere. Medical devices are not something to gamble with — when in doubt, disable ECO mode entirely.
If your power station supports a customizable ECO threshold, here is how to pick the right number for your use case:
Most conservative — only the lowest-power vampire drains get shut off.
Good for:
Balanced — catches most standby drain without affecting active devices.
Good for:
Most aggressive — anything not actively in heavy use gets shut off.
Good for:
How to measure your device's power draw: Plug the device into the power station, turn it on to the setting you care about, and look at the real-time wattage on the display or in the app. Let it run for 10-15 minutes to see the minimum draw. Set your ECO threshold 5-10W above that minimum for safety margin.
No — ECO mode does not reduce output power. It only shuts off the output entirely when load is low. When output is on, you get full power. ECO mode saves battery by eliminating waste, not by reducing capability.
No — ECO mode only monitors and controls output (discharging). It has no effect on charging speed, charge modes, or whether charging works. Charging and discharging are completely separate systems.
Not on most models. On mid-range and premium stations, each output type has independent ECO monitoring. AC can shut off from ECO while USB and DC stay on. Budget models may use a global ECO that turns everything off, but this is less common in 2026 models.
This is the most common misconception. People plug in a low-power device, it turns off after a while, and they think their unit is defective. It is almost always just ECO mode working as designed. Before assuming a hardware failure, try disabling ECO mode and see if the problem goes away.
No — ECO mode is completely safe. Turning outputs on and off does not cause any meaningful wear on the battery or inverter. The inverter is designed for thousands of on/off cycles. Battery wear comes from total energy throughput (charged and discharged), not from how many times you turn output on and off.
If your unit supports it, set a high threshold for AC (where vampire drain is worst) and a low threshold for USB (where you want trickle charging to work).
If ECO mode keeps shutting off things you want on but only briefly, raise the timeout instead of the threshold. A 4-hour timeout means your device has to be idle for 4 hours before shutdown — catches true idle, not pauses.
Always test your ECO settings with your actual devices before you need them (camping trip, storm season). What you think is 30W might actually be 8W on low power, and you do not want to find out at 2 AM.
If you have a device that must stay on and draws low power, run it from the DC/car port if possible. On many units, DC output has lower ECO thresholds or no ECO at all, plus DC-DC conversion is more efficient than DC-AC-DC.
Smart power stations send app notifications when ECO mode shuts off an output. Enable these notifications so you know when ECO kicked in vs. when something is actually wrong.
For off-grid solar setups, use ECO mode plus scheduled output. Schedule AC to turn on during peak solar hours, and let ECO shut it off when nothing is using it. You get maximum utility with zero waste.
Common questions about ECO mode on portable power stations.
ECO mode (short for Economy mode) is a power-saving feature that automatically shuts down output ports when the connected load draws very little power for an extended period. It continuously monitors the output power draw — if it stays below a threshold (typically 10-50W) for a set duration (usually 1-12 hours), the output turns off to prevent wasting battery on idle or standby loads. The goal is to eliminate "vampire drain" and extend battery runtime.
Use ECO mode when you want to maximize battery life and you do not need continuous low-power output. It is great for camping, off-grid use, backup power with intermittent loads, and any situation where battery conservation is important. Do not use ECO mode with medical devices (CPAP), devices that need continuous power, or low-draw devices that must stay on 24/7 like security cameras or sensors.
ECO mode typically saves 5-20% of battery capacity over a full discharge cycle, depending on what you are powering. The biggest savings come from eliminating vampire drain — devices in standby mode that draw 5-20W continuously. For example, a TV in standby at 10W would drain 240Wh per day. ECO mode eliminates that entirely, adding hours of runtime for the devices you actually use. With constant high-power loads, ECO mode saves nothing because the load never drops below the threshold.
ECO mode can usually be disabled in the companion app under Settings → Output → ECO Mode, or by pressing and holding the ECO button on the unit itself (on models with a physical button). The exact procedure varies by brand: EcoFlow uses the Eco app or ECO button, Jackery has a dedicated ECO button, Bluetti uses the touchscreen menu, and Anker uses the app. Some brands let you adjust the threshold and timeout instead of fully disabling it.
CPAP machines on low pressure settings can draw less than 20W, which falls below the ECO mode threshold on many power stations. ECO mode thinks nothing is connected and shuts off the output after the timeout period. To fix this: disable ECO mode completely, raise the ECO threshold if your model supports it, or add a small resistive load (like a 15W light bulb) in parallel to keep the draw above the threshold. Always test before relying on it for medical use.
The ideal threshold depends on your use case. For general use: 10-20W catches most vampire drain without cutting off low-power devices you care about. For maximum battery savings: set it to 30-50W so anything not actively used gets cut. For medical devices or always-on gear: disable ECO mode entirely. Higher-end units like EcoFlow and Bluetti let you customize both the threshold and the timeout duration in the app, so you can fine-tune it for each output type.
No — ECO mode only affects output (discharging), not charging. The charging speed, charge modes (Silent/Standard/Turbo), and charge limits are completely separate systems. ECO mode does not change how fast the battery charges, whether charging works, or any aspect of the charging process. It only monitors the output ports and shuts them down when the load is below the threshold.
For most people, leaving ECO mode on is better because it saves battery and extends runtime for the things you actually use. The only time to turn it off is when you need continuous low-power output — medical devices, always-on sensors, security cameras, and similar. If you find ECO mode frustrating because it turns off devices you want running, try raising the threshold or increasing the timeout instead of disabling it entirely.
Nearly all modern portable power stations have ECO mode or a similar power-saving feature. EcoFlow calls it Eco Mode, Jackery calls it Power Saving Mode, Bluetti calls it ECO Mode, Anker calls it Power Saving Mode, and Goal Zero calls it Low Power Shutoff. Budget models under $200 sometimes skip this feature, but every major brand's mid-range and premium units have it as of 2026.
It depends on the model. On most mid-range and premium units, ECO mode applies per output type — AC, USB, and DC are monitored separately. If only AC has low load, only AC turns off while USB and DC stay on. On some budget models, ECO mode turns off all outputs together based on total load. Higher-end stations like EcoFlow Delta Pro 3 let you customize ECO settings per output type in the app.
