MECOOL KD2 Review: 4K Certified Android TV Dongle with AV1 decoding


Today we have the MECOOL KD2 review for you. MECOOL KD2 is a Google certified Android TV streaming stick powered by the new Amlogic S905Y4 SoC. Besides, the same as KM7 TV Box, the KD2 streaming player is also based on S905Y4 SoC with 4K AV1 decoding support.

We have written about the KD2 streaming dongle many times. As we mentioned, it is a Google certified streaming device, but it is not Netflix certified. However, if you want a fully certified device (Google and Netflix), be sure to read about the MECOOL KD3 Google TV Stick. It is a certified TV Stick based on Android 11 OS with Google TV software. 


Coming back to the MECOOL KD2 streaming player, it does not differ in its operation from the KM7. The main difference between these streamers is the format/design of the device and the number of ports. Features and most specifications remain the same. Even so, we encourage you to read our impressions, which you will find in our MECOOL KD2 review.

Why is it worth getting a streaming player that uses AV1 decoding?

Most of the currently popular streaming services use the latest AV1 decoding. AV1 is a high-performance, royalty-free video codec that provides 20% improved compression efficiency over HEVC/VP9 and manages to save up to 30% in bandwidth for the same image quality.

Review MECOOL KD2: First impressions, settings, overview of features

The KD2 streaming player has a TV Stick / TV Dongle format that ends with a flexible cable terminated a male HDMI 2.1 connector. We have no doubts about the quality of workmanship. Everything is OK. BTW, Check also the earlier MECOOL KD1 streaming stick.

Due to the size of the device, we will not find many ports here. Only USB 2.0 and micro USB to power the device. KD2 Android TV Dongle is powered by a power adapter or via the USB port on the TV.

Streaming stick comes with Bluetooth Voice remote that looks similar to the G10 Android TV / Google TV reference design Bluetooth Voice remote control. Voice remote control featuring Google Assistant, YouTube, Amazon Prime Video, Google Play, Spotify shortcut keys, plus Android TV navigation buttons including a guide button, home and back buttons, direction keys, and a watchlist button. 

Recognition of voice commands via Google Assistant works without major problems. Below pictures.

MECOOL KD2 Conclusions

MECOOL KD2 Android TV Dongle review

MECOOL KD2 is a worthwhile Android TV streamer for home entertainment. As we wrote at the beginning, its features, use and a large part of the specification are the same as for the MECOOL KM7. It is up to you whether you prefer the TV Stick / TV dongle or TV Box format.

KD2 Android TV streaming player is certified by Google, works fast and smoothly, plays 4K video (also with AV1 codec), and streaming video also smoothly. If you are looking for streaming player with a chipset (S905Y4 SoC) that supports the AV1 codec, MECOOL KD2 should satisfy you. 

However, if your streaming player is to be “fully certified” and support Netflix 4K, you should be interested in MECOOL KM2 and the new MECOOL KD3 Google TV Stick (with Google TV).














  • 4K AV1 Decoding via S905Y4 SoC
  • Up to 4K HDR Streaming services
  • Fast and stable work
  • Good video playback
  • Android TV 11, Voice control and Chromecast works great


  • No certified Netflix, only up to 1080p via modified app
  • Bluetooth remote control without air mouse
  • Sometimes the device won't start via the remote control
