Roku Low Power: How to Fix Insufficient Power?

The Roku “low power” warning appears when you power the device from your TV’s USB port. This isn’t enough power for certain TVs. Connect your Roku’s power cord/adapter to a wall socket.

If the Roku “low power” error appears when your Roku streaming player or streaming stick is connected to the USB port of your TV, you must use the Roku power cable/adapter instead.
You may also try connecting your Roku to a different USB port on the back of your television to see if it resolves the issue. Various USB ports have varying power capacities.

Plug in the Roku Power Cord

All Roku streaming players and sticks have a power cord/adapter. Unplug your Roku from your TV’s USB port and connect it to the power supply adapter. Plug in the adaptor.
Online stores sell replacement power cords. Charging cords must fulfill the device’s power standards or they won’t operate. Online charging cords are sometimes cheaper since they deliver less power. This guide lists the voltage and amp output for each Roku device.

How Much Power Does Roku Consume?

Operating Roku players and sticks consume less energy. Roku Ultra requires 4.5 watts of electricity to broadcast 4K HDR video. In addition, Roku Streaming Sticks consume 3 watts of power. Since there is no “off” button on the Roku, it will continue to consume electricity if plugged into an electrical outlet. If you are experiencing the Roku low electricity issue, the device is likely connected to the USB port on your television.

When the TV is off, your Roku turns off and uses no electricity. The TV’s USB connector can only output so much power. USB ports typically generate 2.5 to 7.5 watts (depending on the version). You see the problem. Roku Ultra needs 4.5 watts while streaming, however, your TV’s USB connector only gives 2.5 watts. Using the Roku electricity cable/adapter and putting it directly into an outlet will offer plenty of electricity.

Insufficient Power on Roku

If your Roku isn’t getting enough electricity, you’ll notice many indicators. First, your screen will flash “low power” or “insufficient power.” Roku may blink red instead. A blinking red LED on your Roku device indicates insufficient electricity. This LED should be off or white normally. If your Roku keeps crashing, is unstable, and unpredictable, your electricity supply is probably too low. Low electricity might make your Roku act weird. Fix the Roku’s power supply and it’ll be like new.

Clear Roku’s Cache

People have assumed their Roku had an electricity issue since it kept crashing, although the problem had nothing to do with electricity. If you put your Roku straight into a wall socket using the specific power cord/adapter and it’s still crashing and behaving unstable, clean the cache. Roku’s cache can cause screen freezing, app crashes, sound issues, TV buffering, etc. Start by hitting Home on your remote to get to the main screen.

Wait 2-3 seconds, then hit the following remote buttons nonstop: 5xHome, 1xUp, 2xRewind, 2xFastForward.
Roku should reset twice. Wait 10 seconds before using your Roku when the home screen appears. Your cache is cleared, and your troubles should be gone.

Conclusion!

If your Roku says “low power,” it’s because the USB connector on your TV isn’t delivering enough power. Then plug your Roku in using the power cord/adapter. A flickering red light on your Roku and intermittent activity are signs of low power (like crashing, buffering, freezing, and general instability). If you’ve connected your Roku to an outlet and are still having problems, delete its cache. How’d you fix low power? Please comment!
