Kankun KK-SP3 is a $20 Wi-Fi Smart Socket for Android and iOS

I’ve already featured Broadlink SP1 and SP2 smart socket on this blog.  The former is a simple Wi-Fi smart socket for Android and iOS, and the later adds support for motion sensing and energy monitoring.  They cost respectively about $30 and $45 including shipping. I’ve discovered another cheaper option with Kankun KK-SP3 via DealExtreme ($23.75), but it can also be found on Aliexpress for as low as $19.99 including shipping. If you live in China, It’s available on Taobao for 99 RMB ($15.82). Here are the specs of this smart socket: Power Plug – Three flat-pin plug (Australia type) Wi-Fi – 802.11 b/g/n, 15 dbm.

Bluetooth Slide-out Keyboard Cases for Android Smartphones and iPhones

Yesterday, one reader told me he wished manufacturers would release high-end smartphones with a slide-out keyboard, something similar to what Asus has done with Eee Pad Slider SL101 or Archos with their 101 XS Tablet. So I had a look in case some Chinese manufacturers had done a phablet with a slide-out keyboard and Mediatek MT6588 or MT6592 SoC, but all I could find are some old 2011 or 2012 smartphones with Android 2.3 and low specs by today standards. If you own a best selling phone however such as the Galaxy S4, Galaxy S5 or iPhones, there are some cases with a Bluetooth slide-out keyboard that can add this functionality to your phone. The one pictured above is “QQ-Tech Ultra-Slim Slide-Out Detchable Multifunction Wireless Bluetooth Keyboard Case” for Samsung Galaxy S4  which you can find on Amazon for $23. The case comes with a micro USB cable to charge […]
