If your power bank is not working as expected, follow the troubleshooting steps below to identify and resolve common charging and power-related concerns.
Power bank won't turn on
If the power bank does not turn on or the display remains blank:
1
Press the power button once to wake the display.
2
Connect the power bank to a known working USB-C charger and allow it to charge for at least 30 minutes.
3
Check that the charging cable and wall charger are working properly by testing them with another device.
4
Press and hold the power button for several seconds, then check if the display activates.
5
If the power bank still does not respond after charging, contact Belkin Support for further assistance.
Device is not charging
If a connected device is not charging:
1
Confirm that the device supports charging through the selected port and cable.
2
Disconnect and reconnect the charging cable securely.
3
Try a different charging cable if available.
4
Test a different port on the power bank.
5
Check the smart display for charging activity and wattage output.
6
If charging multiple devices, disconnect the other devices and test charging with only one device connected.
7
Restart the device being charged and try again.
Power bank is not charging
If the power bank itself is not recharging:
1
Use a USB-C PD charger capable of providing sufficient power.
2
Verify that the USB-C cable supports charging and is not damaged.
3
Confirm the wall outlet is working properly.
4
Connect the charger directly to the power bank without adapters or extensions whenever possible.
5
Check the smart display for input wattage information.
6
If no charging information appears on the display, test with a different USB-C charger and cable.
Charging is slower than expected
Charging speed can vary depending on the connected device and charging conditions.
For connected devices
1
Verify that your device supports fast charging.
2
Use a charging cable that supports the required power level.
3
Disconnect additional connected devices to maximize available power.
4
Close power-intensive apps on phones, tablets, or laptops if possible.
5
Allow devices to cool if they have become warm during charging.
For recharging the power bank
1
Use a USB-C PD charger capable of up to 40W input.
2
Ensure you're using a high-quality USB-C cable.
3
Avoid charging in extremely hot or cold environments.
Charging stops unexpectedly
If charging starts and then stops:
1
Check the smart display for any temperature warnings.
2
Disconnect all devices and reconnect them one at a time.
3
Inspect charging cables for damage or loose connections.
4
Verify that the connected device is functioning properly.
5
If the power bank feels unusually hot, allow it to cool before continuing use.
6
If the battery has reached a critical temperature threshold, charging may pause temporarily until normal operating conditions are restored.
Battery drains faster than expected
Battery runtime may vary depending on what is being charged.
Normal causes
- Charging laptops consumes significantly more power than charging smartphones.
- Charging multiple devices at the same time increases power consumption.
- Higher charging speeds use more battery energy.
- Cold or hot environments may temporarily reduce battery efficiency.
To maximize runtime
1
Charge one device at a time whenever possible.
2
Disconnect devices after they are fully charged.
3
Avoid leaving devices connected unnecessarily.
4
Store and use the power bank within recommended operating temperatures.
5
Monitor battery health information using the smart display.
Pass-Through Charging Concerns
Pass-through charging allows the power bank and connected devices to charge simultaneously.
My device charges more slowly during pass-through charging
This is normal. During pass-through charging, the incoming power is shared between recharging the power bank and charging connected devices.
Is pass-through charging supported?
Yes. The power bank supports pass-through charging and can charge connected devices while receiving power from a compatible USB-C charger.
Why does my device only charge at a lower speed during pass-through charging?
To maintain safe operation and manage power efficiently, pass-through charging output may be reduced compared to normal standalone charging. The power bank supports pass-through output up to 15W.
Can I leave devices connected while recharging the power bank?
Yes. This is an intended feature of pass-through charging. However, charging performance may be lower than when charging the device directly from a wall charger.
When to contact Belkin Support
Contact Belkin Support if:
- The power bank will not turn on after charging.
- The display does not function after troubleshooting.
- The power bank will not accept a charge from multiple verified chargers.
- The power bank shows repeated temperature warnings under normal conditions.
- The product exhibits physical damage, swelling, unusual odors, or liquid exposure.
Your safety is important. If you observe any physical damage or abnormal behavior, discontinue use immediately and contact Belkin Support.
