REVIEW: Fire TV Stick 4K Max, the most powerful TV-Stick for streaming

Fire TV Stick 4K Max is the new Amazon TV-Stick that we present today its analysis or review. A small format device that does not offer compatibility with all current streaming services in 4K HDR quality.

The new Fire TV Stick 4K Max is identical to the Fire TV Stick 4K externally but inside we have more computing power and graphics, a device that for now is crowned as the most powerful Stick available. This new Stick also has support for AV1 codec that will be gradually integrated into all current streaming services to offer higher quality with maximum compression, we also have Dolby Vision and Dolby Atmos support. Let’s see in our review how this device performs and how it fares against its rivals.

  • Fire TV Stick 4K Max is available on Amazon from $54.99 (64.99€) with free shipping.

Unboxing Fire TV Stick 4K Max

The new Fire TV Stick 4K Max comes in a cardboard box with the product image and generic information about its main functions. Inside we find the TV-Stick, BT+IR remote control, HDMI cable, charger, micro SD cable, AAA batteries and a small manual of first steps.

The Fire TV Stick 4K Max maintains the identical design to the 4K version, it has a really compact and simple size. On the side we only have the HDMI 2.0 male connector. On one of its sides the only micro USB 2.0 OTG port that allows us to connect some peripherals with a microUSB OTG cable.

This version of the Fire TV Stick 4K Max has a remote with buttons to control our TV thanks to an IR emitter that has on the front, we also have integrated microphone for Alexa and direct access buttons to different streaming services. When starting the device for the first time we have a configuration wizard that will simplify us to find our TV model or compatible soundbar.

  • Remote control: BT + IR Alexa remote control with TV controls / NO Flymouse / YES microphone.

As the only port we have a micro USB OTG connector that allows us to connect extra peripherals thanks to a special micro USB cable. On the motherboard we can see the Wifi 6 + BT 5.0 LE chip and an internal antenna to get coverage. If our TV has a USB with 5V 1A power we can try connecting the TV-Stick without the power adapter, but if the system reboots or shuts down in the middle of use we will have to use the official power supply.

  • Alternative control: We can connect a flymouse, mouse, gamepad or bluetooth or adapter keyboard using an OTG cable. The mouse pointer is not visible on the Fire OS desktop only when entering apps like Kodi or a browser.

Environment and Android system

We start the Fire TV Stick 4K Max, it starts automatically and the system tells us how to configure it. After configuring it we get to the FireOS launcher based on rectangles with very few customization options and in the top row is where we have our most used apps. We have few apps installed, basically a few streaming services. We found that the performance of Fire OS 7.2 is good if we do not demand speed in changing apps but for normal use we can say that it is sufficient.

  • Launcher: We can NOT change the launcher / Android UI rendering at 4K.
  • Multitasking and access: Multitasking NOT available / No Android navigation bars.
  • Languages and Google Play: All the international languajes / Amazon Appstore installed.

  • Power on/off: Only sleep mode / Off mode NOT configurable in settings.
  • Version and root: Fire OS 7 based on Android 9 (32 bit) / NO root / Model kara.
  • Support: Official Amazon support / Firmware upgradeable only by OTA.

Network, storage, RAM and ports

The small TV-Stick Fire TV Stick 4K Max has a RAM memory of 2 GB DDR4 RAM and for its internal storage we have 8 GB eMMC. It has a single micro USB 2.0 OTG port. In the network section it has a Wi-Fi 6 MiMo + BT 5.0 LE wireless adapter, we can connect an Ethernet adapter via USB up to Gigabit (max. 300Mbps). As we see in the test results give good figures, the wifi reaches good speed and has an acceptable range for using an internal antenna.

  • Network: Internal Wifi antenna / Range 42 dBm / Link 5G 1066 Mbps / Ethernet Gibait USB max. 300Mbps / Bluetooth OK.

We found that the performance of the internal storage is fast and moves the system without problems, on the other hand the RAM memory offers speeds in the line of these devices. The USB 2.0 OTG port behaves normally, we can expand the internal storage using a USB drive connected as FAT32 or exFAT.

  • Storage: Total 8GB  – Avaliable 4.2 of 53.4GB / NOT expandable with a USB or SD external memory.
  • RAM: Total 2GB – Free 1GB / DDR4.
  • Read/Write Ports: USB 2.0 OTG / On external USB drives it allows writing if supported by the app.
  • We recommend reading our Tutorial SAMBA on Android networks if we are going to use files from our network PC.

Power and performance

In terms of performance the mini TV-Stick Fire TV Stick 4K Max has the SoC Mediatek MT8696 Quad Core with ARM Cortex-A55 processors at 1.8 GHz and in the graphics section a PowerVR GE9215 GPU which is in the mid-range. This SoC is possibly manufactured in 12 nm, as we have checked the cooling system is adequate and temperatures are low, the chip correctly scales speeds and maintains performance correctly. In general we have enough power for usual streaming apps or KODI, to set a TV-Stick as we see surpasses the S905X4 box.

  • CPU performance: Min 500 MHz / Working  1.0 GHz / Max 1.8 GHz

We test the games running in medium/low quality. In the emulators section we can get at most run some Wii titles, but we will not have problems with 2D games from classic consoles with emulators like Retroarch or from KODI, the EmuELEC system can not be run, as it is not yet compatible.

  • Games and emulators:  IS possible to play titles such as PUBG / Emulators up to Wii / YES Vulkan support.
  • Controls: Compatible with Gamepads BT or cable.

The new Fire TV Stick 4K Max is possibly manufactured on 12nm, has a very low power consumption, the cooling system works well and temperatures are low in basic use. The SoC manages speeds well so as not to overheat.

  • Thermals: Maintains performance up to 88% / Heat zone on the top / Noise 0db
  • Consumption: Off 0.5W / Min 5.5W / Working 8W / Max. 9.5W


Video playback test

Regarding video playback the Fire TV Stick 4K Max thanks to its VPU is compatible with modern video formats such as h.265 or VP9 up to a native resolution 4K@60fps HDR, if it is compatible with the recent AV1 codec that we can use directly on Youtube. We have few video quality settings and also with automatic refresh rate change. We have HDR and Dolby Vision support to get better image to some content.

We can use players like KODI or PLEX without the slightest problem installing the app or using the apk. As for audio we can play DD and DTS up to 7.1 through its HDMI port.

After testing the new Fire TV Stick 4K Max we can say that we are facing a new Stick with a very high power. This small device has enough hardware to play 4K HDR multimedia, use players like KODI, PLEX or for IPTV streaming. The system is Fire OS moves properly and as we already know this system has many limitations compared to Android TV, a point that we will have to take into account if we want more or less freedom. This new Stick also now has Wifi 6 which offers a very good network performance.

In terms of raw power the Fire TV Stick 4K Max can run any apps or game on Fire OS without performance problems, certainly this SoC exceeds even the popular S905X4 or even Chromecast Google TV. The new Bluetooth remote with Alexa included is simple but functional, plus we can connect it with our TV or sound bar. This TV-Stick keeps temperatures very controlled, a positive point that gives security and reliability in the long term.

In short, the Fire TV Stick 4K Max is a powerful product and ideal for 4K HDR streaming. If we are looking for a device with long term support, fluid and video quality is an option, pity the limited Fire OS.

Where to buy

“DC Adapter 5.25V 1A”
“has a very low power consumption”
“Min 5.5W / Working 8W / Max. 9.5W”

This doesn’t compute. Quoted power is by no means a low power for a stick and its all above power supply specification. So what is true?

“via SPDIF stereo only”
Copy&paste I guess? 😉


Regarding “Video Settings: NO image quality settings / HDMI-CEC available, see manual / Auto refresh change only on Prime, KODI or PLEX.”

Could you please explain how to make Fire TV Stick change refresh rate from 60 to 24 in Kodi? In Kodi settings I changed “Adjust display refresh rate” to Always. But it doesn’t change during playback.



sorry but we can change the launcher just put a compatible launcher manager and then we can put any launcher that works in Android TV mode, concerning the 4k there 3 or 4 software that works very well with the Fire Tv max in local or streaming. I tested some software and the Fire Tv max it does the job without problem, and I prefer the new launcher that recognizes all the apk icons that I installed than the one of Fire tv max that recognizes not the apk icons but that makes them shot without problem.


Expensive??? WTF… Cheapest certified streaming player!!! Where you can find 4k player for less???? i bought in promotion for ~35euro
