We take a look at three popular Qi wireless charging solutions and put them head to head in Jerry's bedroom
Qi (pronounced Chee, and is totally a word no matter what Words with Friends says) is a wireless standard developed in 2009 by the Wireless Power Consortium. The standard itself covers inductive power transfer over short distances -- up to four centimeters -- and uses a electromagnet embedded in a transmission pad to induce current in a coil on the back of the thing you're charging. In our case, that means a Nexus 4 smartphone.
With big-name device makers like Samsung, HTC, LG, Motorola and Nokia (as well as others) using the standard, it is slowly emerging as the winner in the obscure wireless charging war that goes on in cubicles all over the world. Long live Qi! On a serious note, it's an open standard with over 100 companies in Asia, Europe and North America cooperating to set a good standard that everyone can implement. That's good for business, and good for consumers in the long run. Of course, there will always be companies that buck the trend and take another path, but for now if you're going to spend your hard-earned money on a wireless charger that you should be able to use for the life of multiple devices, Qi charging is the way to go.
Because it's a standard, there are quite a few different companies making the base stations (a fancy term for the charging pad). I took a look at the three most popular and put them head to head to see which one I'd recommend. While I used a Nexus 4 for my tests, these chargers should work for any Qi-compatible phone with a flat back. Jump past the break and see who wins the Qi charger showdown.
