Flagship mobile devices often come with wireless charging capability, but there’s an easy way to add (Qi) wireless charging to almost any smartphone, or possibly tablet, thanks to wireless charging receivers that simply connect to the micro USB port of your mobile device, and can be purchased for as low as $7 on Aliexpress, Ebay, DX.com, etc… I’ve also seen Adafruit made a Qi Wireless Receiver module for Arduino with a 2.54mm pitch connector.
They come in various sizes and shapes, but they’re all extra thin (1 mm), with a micro USB connector oriented upwards or downwards depending on your mode, and a thin cable, that allows you to place it inside your phone between the battery and the phone cover as shown in the picture below. It’s not always possible however, as for example the receiver would cover my phone’s rear camera lens, but you could always attach it to a protective cover, or a car phone holder.
Once the installation is complete, you are ready to charge your phone with a wireless charger.
Specifications ARE different between modules, but typically look like:
- Dimensions – 62 x 45 x 1.1mm
- Net weight – 2.5g
- Input Power – 3.5W
- Output – DC5V/650mA (Average)
- Charging current – DC5V/500mA (Average)
- Working life – 4000 charges
