Roku Low or Insufficient Power (Quick Fix)

Roku Low

When the Roku “low power” error occurs because the Roku “power cable/adapter” has not been included with the streaming media player or streaming stick, then the error can occur.

You will receive this Roku “low power” warning if you power your Roku device through the USB port on your television. Occasionally, some televisions are unable to provide sufficiently high power.

Rather than using a power adapter, you should plug your Roku directly into a wall power outlet.

As an alternative, you might want to connect your Roku to a different USB port on your TV to see if that makes a difference. There are different power capabilities for different USB ports.

Utilize the Roku Power Cord Adapter

With all Roku streaming players and streaming sticks compatible with Roku, you will receive a power adapter or cord with one.

You can easily do this by simply taking your Roku out of its USB port on the back of your TV and re-plugging it into the USB port on the Roku power supply adapter. Then plug the adapter into any wall outlet.


A new power cord can be ordered online if you’ve lost your original. The charging cable must be able to supply the correct amount of power to the device they are powering, or else it won’t work.

Frequently, charging cables online is cheaper since they don’t provide the same power. When in doubt, you should check the Roku Power Supply Guide and your particular Roku device.

With the help of this guide, you will learn how much voltage and amp output every Roku device requires.

 Online power supply adapter buyers can take advantage of this information to find a reputable supplier. PWR makes a good power supply adapter.

How much power does Roku use?

When used in the normal course of things, Roku streaming players and sticks typically only use a small amount of power while they are powered.

For example, If you are streaming 4K HDR content with your Roku Ultra, your device consumes approximately 4.5 watts. The Roku Streaming Stick would consume approximately 3 watts if you streamed through it.

Roku devices can be reduced in energy consumption by about 2 watts when they are not being used (since Roku devices cannot be turned off, energy is consumed whenever they are plugged into a wall socket).

Because you are experiencing the Roku low power error, your Roku is likely connected to the USB port on the rear of your television set. As a result, if the TV is off, the Roku will also be off and not use any power.

What is the purpose of all this?

 Indeed, the USB port on the back of your TV can only produce a limited amount of power. It is common for USB ports to output between 2.5 and 7.5 watts (depending on the particular model).

Therefore, it is clear that there is a potential issue here. When streaming on the Roku Ultra, the device consumes approximately 4.5 watts of power, but your TV’s USB port provides only 2.5 watts.

Plugging your Roku directly into an outlet and using the included Roku power cord will provide plenty of power for your device.

NOTE:  If your Roku is not working, you can try plugging it into a different USB port on your television to see if that will help fix your power issue. Another USB port may be able to supply enough power since different USB ports have different power capabilities.

Signs that your Roku device is not getting enough power Roku Low

When your Roku device doesn’t receive enough power, you’ll see several obvious signs.

Two indications will appear on your screen. First, there will be an error message saying “low power” or “insufficient power.”

Note: You’ll notice your Roku blinking red and behaving sporadically most of the time. It is common to see both at the same time.

Ensure your Roku device’s cache is cleared

It has been reported that some Roku users thought they had a power supply issue when they noticed that their Roku kept crashing all the time. They later discovered that the issue had nothing to do with the power supply.

Your Roku might need to clear its cache if it crashes and acts unstable overall, even when plugged directly into a wall outlet using the dedicated power cord/adapter. Roku’s cache can cause screen freezing, apps crashing, poor sound quality and TV buffering.

In these instances, try pressing the Home button on your remote control to reach the main menu.

Upon receiving the following message, wait 2-3 seconds and enter the following sequence on your remote control (pressing the buttons non-stop). Press home five times, up one time, rewind two times and fast forward two times.

Clear the cache of your Roku device

Rebooting should be done at least two or three times. It can take a few seconds for the home screen to appear and stay up before you can use your Roku again. It’s done, your cache has been cleared, and hopefully, your problems are solved.

Your Roku is giving you a “low power” warning because it is plugged into the USB port of your television, and that port is not able to provide enough power for it to operate.

Besides the pop-up alert on your Roku, other signs that it’s running low on power are a blinking red light on the device and general sporadic behaviour (like crashing, buffering, freezing, and general instability).
