How to Fix Roku Low Power / Insufficient Power issue

We will now provide you with different ways to help you fix your Roku Low power or Insufficient power issue. We advise you to keep trying the other methods if one fails to work for you.

Plugging your device into an alternate USB port

The USB ports in your Television have different power ratings and provide different amounts of power to the devices plugged into them.

Here, it might be possible that the USB port in which you have plugged the device cannot provide enough power; therefore, unplug your Roku from that USB port and plug it into an alternate USB port to see if it helps.

Plugging your device into a wall outlet

Instead of using your TV to power your Roku, use the charger by directly plugging it into a power outlet. The charger you get with your Roku device provides the right amount of voltage and functions correctly.

Replace The USB Cable

Old and faulty USB cables can often cause insufficient power issues with your Roku devices, which may fail to give enough power to the device, resulting in low voltage and hence low power.

Try to use the original Roku USB cable instead of the cheap cables that are best for optimal performance.

Connect the Power Adapter Properly

Ensure to plug in the adapter to your Roku device properly. If it’s loose, it may hinder your device from functioning properly by not supplying sufficient power.

Check and make sure that the adapter is plugged correctly into the socket and also inspect that you have securely connected the charger to your Roku device.

Remove the Extensions

We recommend you avoid using extension cables as these cables often malfunction, causing the Roku device to overheat and, therefore, display the message.
