QFUP USB Power Cable for Fire TV Stick 4K Max - Powers Directly

In this review the QFUP USB Power Cable is presented as a simple way to power a Fire TV Stick 4K Max and similar streaming sticks directly from a television. The bottom line: this cable is for people who want to eliminate the dangling power brick and messy wiring and still get stable power for 4K streaming. It delivers a consistent voltage and current while removing the need for an AC outlet, and the review focuses on how easy it is to install, the device compatibility, and whether it reliably fixes "insufficient power" errors.

Key Features

• Direct TV Power: Allows a streaming stick to draw power from the TV USB port so the AC adapter and suspended cable are no longer needed, creating a neater setup.
• Universal Compatibility: Works with Fire TV Stick models including the 4K Max, as well as Roku and Chromecast streaming sticks and other HDMI devices that accept micro USB power.
• Stable Output: The integrated 5V power conversion module provides a consistent voltage and current output to avoid shutdowns or instability during playback.
• Protection Circuits: Multiple built-in protection circuits help ensure safe, steady operation when the stick is powered through the TV's USB port.
• Easy Installation: Plug-and-play design requires only inserting the micro USB into the stick and the USB A into the TV, making setup quick and straightforward.
• Enough Power for 4K: Capable of delivering up to 5V/2.1A to support uninterrupted 4K streaming on compatible sticks.

Who It's For

This accessory is best for cord-conscious TV owners who use a Fire TV Stick 4K Max or similar streaming stick and want a cleaner look behind the TV without running to a wall outlet. It is ideal for users who place the stick close to the TV and who rely on the TV's USB port for power while the TV is on.

It is less suitable for users who need their streaming stick to stay powered when the TV is turned off or for setups where the TV has no USB port or supplies very low USB power. For those configurations, a standard AC adapter or powered USB hub may still be required.

Pros & Cons

Pros

• Removes the AC power brick and reduces wire clutter for a tidier installation.
• Simple plug-and-play setup that most users can install in seconds without tools.
• Delivers stable power with built-in protection circuits and up to 5V/2.1A output for 4K playback.
• Works across many streaming sticks, including current Fire Stick models, Roku, and Chromecast.

Cons

• Only supplies power while the TV is turned on, so the stick will not stay active when the TV is off.
• Requires the TV to have a USB port that provides sufficient power; very low-power ports may still cause issues.
