$58 QT900 “AirplayCast” Android Mini PC Features AllWinner A31s Processor

There are few AllWinner A31 powered HDMI TV sticks on the market such as CS868 and Measy U4K, but Q900 is the first I come across with AllWinner A31s, the low cost version of AllWinner A31, with a lower LCD screen resolution capability, which is not used in this type of device… The dongle appears to be also called AirplayCast to boast Airplay and Miracast support, which is now available on most Android TV dongles…


QT900 specifications:

  • SoC – Allwinner A31s quad core ARM CortexA7 @ 1.0GHz with PowerVR SGX544MP2 GPU
  • System Memory – 1GB DDR3
  • Storage – 8GB + micro SD slot up to 32GB
  • Video Output – HDMI 1.4 (up to 1080p)
  • Connectivity – Dual band Wi-Fi 802.11 b/n, Bluetooth 4.0
  • USB – 1x USB 2.0 host, 1x micro USB OTG, 1x micro USB for power
  • Misc – Recovery Key ?
  • Power Supply – 5V/2A

The device runs Android 4.2.2, and comes with a short HDMI cable, a 5V/2A power adapter, and a user’s manual in English and Chinese. It should also run XBMC 13 fine as AllWinner A31(s) is one of the supported SoC for hardware video decoding.

SUPA CHARGEDiOS got hold of a sample (Cozyswan QT900) a couple of months ago, and shot an unboxing video, as well as a quick test of Airplay mirroring with an iPad @ 5:16.

I’ve first found the device via Geekbuying which sells it for $68.39, but it’s also available on several shops on Aliexpress for $58 and up.

  1. Hi all – I have had one of these for a couple of weeks and my overall experience with it is good. However, to help other users who are new to this device here are a couple of pointers…

    1) If you receive the unit and it is stuck on firmware 1028, you will not be able to update it over the web. To manually update it, I found the instructions and required files here: http://www.faddishmall.com/consumer-electronics/projectors/qt900-new-2014-the-only-one-andriod-tv-dongle-support-airplay-mirroring-ipush-dlna-for-apple-iphone.html

    2) On restarting the device I find that all clock/date/wifi settings are set back to default – which is a bit of a pain. For example, I want my QT900 to always create its own personal hotspot upon reboot but it changes back to normal wifi and looks for existing wifi networks. I therefore have to re-enable the ‘personal hotspot’ settings in the main Settings panel.

    3) After updating all elements of the dongle to the later versions, visually quite a bit has changed but the boot time is now some 20-30 seconds longer.

    Any advice on points 2 and 3 would be gratefully received!
