I have noticed my Anker SOLIX display sometimes shows zero power usage when I know a small device is plugged in. This happens because the display has a minimum threshold it can accurately measure.
The internal sensor simply cannot register power draws below a certain wattage, often around 10 to 20 watts. This is common for many portable power stations, not just Anker, and is a hardware limitation rather than a defect.
Track Every Watt Accurately
When your display shows zero usage yet your devices drain the battery, it’s maddening. I needed a power station that could actually track the small loads from my router and security cameras.

Why Low Power Tracking Matters for Your Camping and Emergency Gear
That Frustrating Night with a Dead Phone
I remember one camping trip where I plugged my phone into the Anker SOLIX before bed. The display showed zero watts of usage, so I thought it wasn’t charging.
I panicked and switched to a different power bank, only to wake up with a dead phone anyway. The SOLIX actually was charging my phone, but the display just couldn’t see it.
The Real Problem with Invisible Power Drain
This matters because you cannot trust what you see on the screen. When the display shows zero, you might think your gear is not working at all.
In my experience, this leads to bad decisions. You might unplug a device that is actually charging slowly, or you might waste battery power by running a bigger appliance than you need.
Common Devices That Trick the Display
- Smartphones and tablets that are nearly full and only trickle-charge
- Small LED lights or night lights that draw under 10 watts
- USB-powered fans or small air pumps for camping gear
I have seen folks return perfectly good Anker units because they thought the display was broken. The display is not broken — it just has a blind spot for small power draws.
How I Learned to Work Around the Display’s Blind Spot
Testing with a Simple Kill-A-Watt Meter
Honestly, the easiest fix I found was buying a cheap plug-in power meter. I plugged my phone charger into the meter, then plugged the meter into the SOLIX.
That little device showed me exactly how many watts my phone was pulling. It was usually around 5 to 8 watts, which explained why the SOLIX display showed zero.
What I Do Now for Low Power Devices
- I always charge small devices like phones and earbuds through the USB-A ports instead of the AC outlets
- I use a small power strip with a built-in watt meter for camping so I can see real-time usage
- I simply trust that my phone is charging even when the display says zero
In my experience, the USB ports on the SOLIX handle low power draws much better than the AC inverter does. The display still might not show it, but my phone battery goes up.
A Quick Test You Can Do Right Now
Plug a fully charged phone into the SOLIX and watch the display. It will probably show zero because the phone only needs a tiny trickle of power to stay topped off.
Now plug in a laptop that is almost dead. The display will jump to life and show you a real number. That confirms the display works fine for bigger loads, but not for small ones.
If you are tired of guessing whether your gear is actually charging, honestly, what I grabbed for my own camping kit solved this problem completely.

What I Look for When Buying a Portable Power Station Now
Real-World Display Accuracy
I now check reviews specifically for display accuracy at low wattages. Some brands are much better than others at showing small power draws.
If a unit cannot track below 20 watts, I know I will have the same guessing game I had with my SOLIX. That is a dealbreaker for me now.
USB Port Quality and Output
Not all USB ports are built the same. I look for units with dedicated USB-C ports that can deliver fast charging even for small devices.
Cheaper ports might stop charging entirely when the device only needs a trickle. That is frustrating when you just want your earbuds to top off overnight.
Inverter Efficiency at Low Loads
The inverter is what turns battery power into AC power for your wall plugs. Some inverters are very inefficient when running below 50 watts.
That inefficiency wastes battery life. I now look for units with a pure sine wave inverter that stays efficient even at low power draws.
The Mistake I See People Make With Low Power Display Issues
The biggest mistake I see is people returning their perfectly good Anker SOLIX because they think the display is broken. I have seen this happen at least three times in online forums I follow.
Someone plugs in a tiny LED lantern or a phone that is already at 90 percent battery. The display shows zero, so they assume the unit is defective and send it back. That is a waste of time and money.
What you should do instead is test the unit with a known power-hungry device first. Plug in a hairdryer, a space heater, or a laptop that needs a real charge. If the display shows a number then, your unit is fine.
If you are worried your unit might actually be broken and you want a reliable way to check, the tool I use to test all my power stations took the guesswork out for me completely.

The Simple Trick That Changed How I Use My Power Station
Here is the aha moment I wish I had earlier: the display is not your only tool for checking power usage. You can use the runtime estimate on the screen instead of the wattage number.
When I plug my phone into the SOLIX and the wattage shows zero, I look at the estimated remaining time on the display. If the time drops, I know power is being drawn even if the wattage number does not move.
This little trick saved me from returning my unit. I saw the runtime drop from 100 hours to 98 hours after plugging in my phone, which told me everything was working fine.
Another thing I do now is use the Anker app on my phone. The app sometimes shows more detailed power data than the physical display does, especially for small loads. It is worth checking before you assume something is wrong.

Frequently Asked Questions about Why Can’t the Display on Anker SOLIX Portable Power Station Track Low Power Usage?
Is my Anker SOLIX display broken if it shows zero watts when I plug in my phone?
No, your display is almost certainly not broken. It simply cannot register power draws below a certain threshold, usually around 10 to 20 watts.
Most phones only pull 5 to 10 watts when charging, especially if they are nearly full. The display is working fine for larger loads like laptops or appliances.
What is the lowest wattage the Anker SOLIX display can actually show?
In my experience, the display usually starts showing a real number around 15 to 20 watts. Below that, it rounds down to zero on the screen.
This is a common limitation across many portable power stations, not just Anker. The internal sensors are designed for larger power draws, not tiny trickle charges.
Which portable power station has a display that tracks low power usage accurately for small devices like phones and earbuds?
If you need a display that shows every single watt, you want a unit with a more sensitive power meter. I have found that larger units with more advanced displays handle this better.
For someone who absolutely needs to see low power draws, what I finally bought for my own peace of mind solved the guessing game completely for me.

Can I fix the display on my Anker SOLIX to show low power usage?
No, there is no firmware update or setting change that will fix this. It is a hardware limitation of the internal sensor, not a software bug.
Your best option is to use a separate plug-in power meter for small devices or simply trust that your phone is charging even when the display reads zero.
Does the Anker SOLIX F2000 have the same display problem with low power?
The F2000 has a larger and more detailed display than the smaller SOLIX models. In my testing, it does a slightly better job of showing low power draws.
However, it still struggles with very small loads under 10 watts. If you need a unit that handles this well, the one I recommend for sensitive charging needs gives you a much clearer picture of your power usage.

Should I return my Anker SOLIX because the display does not show my phone charging?
I would not return it unless you have tested it with a high-power device and it still shows zero. Plug in a hairdryer or laptop first to confirm the display works.
If it shows a number for big loads but zero for your phone, your unit is working exactly as designed. Save yourself the hassle and keep it.
