Amazon - USB Power Cable for Fire TV Stick (Eliminates the Need for AC Adapter) - Black

Unlike simple USB cables, Mission USB Power Cable for Amazon Fire TV 4K includes special power booster technology that increases the peak power output of your USB port. By storing excess power in the embedded battery and then releasing it when your Amazon Fire TV 4K demands more power than your USB port can handle, you can be sure to avoid brownouts and resets, even during the most demanding 4K streaming and gaming.

Avoid hassle - Eliminates the need to find an AC outlet near your TV by powering your Amazon Fire TV Stick directly from the TV's USB port. This USB power cable is compatible with all Fire TV sticks.
