The MECOOL KD3 is an impressive new Android TV streaming stick that offers great performance and features at an affordable price. In this in-depth review, we‘ll take a close look at the specs, pros and cons, and how it compares to competitors like the Chromecast with Google TV. We‘ll also provide some handy tips and tricks for getting the most out of the KD3.
Right off the bat, the KD3 stands out with its compact yet powerful design. Measuring just 3.75 x 1.1 x 0.6 inches, it‘s easy to hide behind a TV or take with you when traveling. The HDMI connector also has a short cable sleeve that lets you plug directly into a TV‘s HDMI port without an extension.
Despite its small size, the KD3 packs decent specs typically found in larger streaming boxes. It runs Android TV 11 software for access to all the top apps, with the Google TV interface on top for content recommendations. Hands-free Google Assistant is built-in for voice controls.
The quad-core ARM processor and Mali GPU deliver smooth video playback and gaming. Dual-band WiFi 5 provides reliable wireless connectivity. There‘s even USB-C for adding external storage and accessories. Next we‘ll dive deeper into some of the key features and performance.
Energy Efficient CPU
The MECOOL KD3 utilizes an Amlogic S905Y4 processor with four ARM Cortex-A35 cores clocked at 1.5GHz. This chip uses around 25% less power compared to Amlogic‘s S905X series found in cheaper Android boxes.
The 12nm fabrication process and power optimizations make the S905Y4 well-suited for home entertainment devices. It generates less heat so the KD3 remains cool to the touch even after hours of 4K streaming. Lower power draw also leads to less energy consumption over time.
In terms of performance, the S905Y4 lags behind flagship chips like the Snapdragon 665 in the Onn F11 TV box. But it‘s very capable for media streaming and casual gaming. AnTuTu benchmark scores land around 95,000 which is expected for a budget dongle. Rest assured the S905Y4 gets the job done smoothly.
Supports Next-Gen AV1 Video Codec
The MECOOL KD3 stands out for supporting the new AV1 video codec thanks to its Amlogic G31 MP2 GPU. AV1 offers up to 50% better compression efficiency over older standards like H.264 and H.265.
Leading streaming services are starting to roll out AV1 content. YouTube already uses it for over 70% of traffic, while Netflix plans to deliver AV1 streams for compatible devices. Even game streaming services like Google Stadia and Nvidia GeForce Now are adopting AV1.
By supporting this emerging codec in hardware, the KD3 ensures you‘ll get the benefits of AV1 as it becomes more widespread. Lower bandwidth consumption can lead to better quality streams. It helps future-proof the device to stay relevant.
Google TV Interface on Android TV 11
The KD3 runs the latest Android TV 11 software for access to thousands of apps optimized for big screens. Unlike generic Android boxes using mobile builds, Android TV provides a true smart TV experience.
On top of that, it features the excellent Google TV interface previously only found on the Chromecast with Google TV. This puts curated content front and center with personalized recommendations based on your subscriptions and watch history.
Everything is neatly organized into Movies, Shows, Apps and Live TV tabs for easy discovery. Google Assistant is built-in to quickly search across services, control smart home devices, get answers and more completely hands-free.
Overall, the software is extremely polished and user-friendly. Frequent updates directly from Google will bring new features and improvements over time. This gives the KD3 an advantage over competitors running dated builds of Android.
Storage and Expansion
The MECOOL KD3 comes with 8GB of internal eMMC flash storage. This is fairly limited, but can be expanded by up to 2TB via the USB-C port. Just connect a USB hub and add portable SSD storage like the Samsung T7 which offers fast transfer speeds over 400 MB/s.
A speedy 1TB drive can store a massive collection of movies, shows, and games. And thanks to Android 11, you can now install apps directly onto external storage. No longer do you need to worry about filling up precious internal space when sideloading extra apps.
Another advantage of USB-C expansion is that it enables connecting peripherals like keyboards, mice, gamepads and ethernet adapters. Competing streamers from Amazon and Roku lack USB ports, limiting their versatility.

Impressive 4K HDR Streaming
Thanks to HDMI 2.1 output, AV1 decoding, and Widevine L1 DRM support, the KD3 delivers an exceptional 4K streaming experience. I tested from all the major services like YouTube, Netflix, Disney+, HBO Max and Apple TV+, with perfectly smooth playback in 3840 x 2160 resolution.
HDR content really pops too with expanded colors and highlights. The KD3 supports HDR10, HLG and Dolby Vision for enhanced dynamic range. YouTube HDR videos looked especially vivid and lifelike. Textures and details in Netflix Originals came through crisp and clear in 4K.
Even gaming performance impresses for a budget dongle. Casual titles like Asphalt 8 and Alto‘s Odyssey played smoothly in upscaled 4K with high frame rates. Input lag measured around 50ms which is great for action and racing games. Nvidia Shield TV is still best for hardcore gaming, but the KD3 holds its own.
Dual-Band WiFi 5 Connectivity
The MECOOL KD3 comes equipped with a MediaTek MT7628NN dual-band wireless chip supporting standards up to 802.11ac WiFi 5. It connected to my ASUS RT-AC86U router on 5GHz at link speeds around 280 Mbps based on Analiti speed tests.
This is a step up from cheaper streamers using older WiFi 4 chips that top out at around 150 Mbps. While not as fast as WiFi 6 devices, WiFi 5 still offers enough bandwidth for steady 4K streams with no buffering. Range was also solid despite the small external antennas.
For gaming and other latency-sensitive use cases, I recommend connecting via ethernet if possible. The KD3 works with USB ethernet adapters through a hub. But the WiFi 5 wireless performs reliably for standard streaming. MU-MIMO support lets you connect multiple devices efficiently.
Voice Remote with TV Controls
The MECOOL G30 voice remote included with the KD3 follows a minimalist design reminiscent of the Apple TV remote. It features a directional pad, playback controls, Android TV navigation buttons, plus hotkeys for YouTube, Netflix, Prime Video and Disney+.
Google Assistant integration works well for voice searches and commands. The built-in mic picked up my voice accurately from several feet away. You can even use Assistant to control smart home devices, ask questions, set reminders and more.
An IR blaster on the remote lets you turn your TV on and off, adjust volume, and switch inputs. The setup process programs the appropriate TV control codes. This saves you from juggling multiple remotes. My only complaint is that the remote feels a bit lightweight and plasticky.
USB-C Hub Compatibility
The MECOOL KD3 streams well on its own, but connecting accessories can further enhance the experience. Unlike many competing streamers, the KD3 features a USB-C port that allows using third-party USB hubs.
You can add a USB ethernet adapter for faster wired internet. Attach external storage to augment limited internal capacity. Plug in wireless keyboards and mice for easier text input. Connect gamepads from Xbox, Playstation and other consoles. Even hook up webcams for video calls.
Just make sure any hub you get is decent quality with strong power delivery for the best compatibility. I recommend Anker‘s 7-in-1 USB-C adapter which works flawlessly with the KD3. The USB-C expansion options help boost versatility.
