Dual zone wireless qi charger (charges two phones simultaneously). This seems to be a decent price for the twin charger, as I paid the same amount for the single charger version from JB not long ago, and even the wireless charging card RRP is around $29.95 by itself (not that anyone here would ever pay RRP right?)

It comes with a wireless charging card for either a Galaxy S3 or S4 (there are two different packages to choose from) , which you install underneath the battery cover. I have one installed in my sister's S3 and it works like a charm. http://mint-technology.com.au/items/istyle-qi-charging-card-…
I can confirm that it works well with both a Galaxy S3 and Nexus 4.
The light on the front illuminates red when charging, and changes to blue when charged. It also has a 2.1A usb output on the back which comes in handy for charging tablets such as Nexus 7 2012.
I can't comment on how long the wireless takes to charge since I usually just leave it on overnight, but there does seem to be a "characteristic" where it'll sometimes stop charging completely once the phone is fully charged. It's happened about a half dozen times now, so my phone will be at 80-90% in the morning occasionally. It might be an overload protection, but I don't really know. I have this on my bedside table and the Kogan one installed in my car, so my phone is never really in danger of running out of battery these days.
Does this charge 2 units at once or just 1?
