I have been using the Wireless charging pad and card for a few weeks now and love it. I also noticed that the charging pad works with my friends LG Spectrum 2 and a few other devices with the Qi Wireless charging adapter added to it. This is easily the best charging pad there is for the Galaxy S4 and I would recommend it to anyone looking for Wireless charging for any device. The price is only $35 from Amazon.com: CHOE Qi Wireless Charger Kit for Galaxy S4 I9500 (Wireless Charging Pad and Wireless Charging Receiver Included): Cell Phones & Accessories, here are some photos:
