Why does my ScreenBar Halo light flash?

05-08-2023

The light usually flashes when Halo’s power supply (output is less than 5V/1.3A) is insufficient.
Please change to another USB port of devices or USB adapter in which the power supply with an output voltage of at least 5V and a current of 1.3A or above.

We recommend using a power supply with an output voltage of 5V and a current of 1.5A or above to optimize the lamp’s light.

If you are unsure about the output information of your USB devices, we recommend using a USB adapter on ScreenBar Halo directly.

And before using a USB adapter, please have a look at your USB adapter specification for output information. You can find related output information shown on the USB adapter below:
OUTPUT: 5V ⎓ 1.5A

Please DO NOT use the USB extension cable for ScreenBar Halo. It will cause light flashes or abnormal operations as well.
