Wireless charging is a beautiful concept that fails to live up to its promise in reality. That’s not to say it’s unusable – far from it. I’d put wireless charging pads in the same place as Wi-Fi was some years back – useful when it works, but frustrating to get working properly.

The little iQi panel goes some way to fixing up the main problem of wireless charging on the iPhone. Because it’s not built in, you usually need a bulky case to pair with the charger itself. The iQi is so tiny it can be used with any case.

Steve Jobs famously argued that if five million people used the Mac, cutting its boot time down by 10 seconds would save the equivalent of at least 100 lifetimes per year.

Taken on an individual basis, it’s difficult to know how many minutes of your life will be saved by using the KoolPuck Wireless Charger — but it’s almost certainly less than an hour over the lifespan of your typical iPhone.

That doesn’t really matter, though. In an age of convenience, the idea that you can charge your iPhone by simply placing it down on a massively wireless charger is a tempting one. Straightforward, attractive, and tiny, FoneSalesman’s iQi solution seems to tick all the boxes.

So how does it measure up?

I don’t know what it is with wireless chargers and the letters Q and I, but what I do know is that the iQi is the first one I have actually considered using. You see, instead of a fat case to hold the induction circuits, or the flux capacitor, or whatever it is that makes wireless charging possible, the iQi is a tiny slim sheet that slips inside your existing case.
