What is the go.roku.com/lowpower Roku Low Power Issue?
As mentioned earlier, this issue appears when your Roku device doesn’t receive enough power to run its crucial components. When this happens, your Roku device will display the following error message on the screen:
“Insufficient Power: The USB port on your TV will not power this Roku device. Please use a USB power adaptor. go.roku.com/lowpower”
Along with this, your Roku device will start to blink a red light compared to the normal white light. In this case, your Roku device doesn’t have enough power; if it displays a solid red light, immediately unplug it from your smart TV as your Roku device is overheating.
In addition, these common reasons can contribute to the Roku Low Power issue:
- Incompatible USB Port – On average, your smart TV’s USB ports provide a wattage of 2.5 to 7.5 watts. To compare, a Roku streaming stick uses near to three watts of power, and a Roku Ultra can go as high as 4.5 watts. Do note though that these numbers can go lower if the Roku device is idle or not used.
When your USB provides the bare minimum (2.5 watts) or lower than the required number of watts, you will encounter the low power alert message from your Roku and other device indicators.
- Faulty USB Cable – If you’re using an old USB cord for your Roku device, there’s a high chance that it is damaged due to wear and tear. You can try using the original USB cord that came along with your Roku device or try to buy a new one.
How to Fix Roku Low Power Error
Once you face this error message on your smart TV screen, you can follow these simple and easy-to-do tricks to solve the Roku Low Power error. Make sure to follow each fix and see which one worked for you the best.
Fix #1: Plug Your Roku Device Into Its Power Adapter
Since this is recommended by Roku, you’ll need to try this out first. Once you purchase a Roku device, it will come with a compatible power adapter or power supply. In this fix, you’ll just need to unplug the USB cord on the back of your smart TV and plug it into the power adapter. Then, you can plug it into a wall outlet nearby.
This will allow a direct supply of power to your Roku device, therefore powering it up sufficiently. To make sure that your Roku comes with the right power supply, you can learn more from this support article from Roku.
Also, check for damages on your power adapter and the USB cord. Immediately replace any damaged equipment to avoid risks such as overheating and electrocution.
Important: Refrain from using extensions and busy power strips as this can lead to a lack of power supply and overheating. If you can, plug your Roku’s power supply directly into a wall outlet.
Fix #2: Try Using A Different USB Port
If your smart TV has two or more USB ports, you also can try plugging the USB cord onto the other ports and see if the Roku Low Power error disappears. As mentioned earlier, the USB ports on your smart TV can have different wattages; trying out other ones might fix this issue permanently.
Additional Fix #3: Power Cycle Your Roku Device
Once your Roku device turns on normally, it can sometimes have bugs that make it inoperative. Some users have reported that their Roku device crashes, freezes, and has unnecessary buffering when watching TV shows. If you’re experiencing this, you can try to power cycle your Roku device.
To perform a power cycle on your Roku device, follow these steps:
- Turn off your Roku and unplug the device from its power source.
- Wait for thirty seconds to re-initialize its internal components.
- Plug its power adapter back into the outlet and turn on your Roku.

- Turn on your Roku device and using its remote, go to Settings > System.
- Select Power and choose System Restart.
- Select Restart and wait for the Roku device to turn on.
- Check if the device works normally.
Additional Fix #4: Clear Cache Data On Your Roku
If you’ve been using your Roku device for a while, the cache can eventually fill up your Roku’s internal storage. Although it is designed to help the apps on your Roku device to run faster, the old cache can also lead to bugs when it’s not deleted.
To clear up the cache data on your Roku device, follow these steps:
- Turn on your Roku device and go to the Home screen.
- Next, press the following button combination on the remote: press Home five times, Up one time, Rewind two times, and Fast Forward two times.
