Japanese wireless charging company Murata has demonstrated a new contactless-charging system for the iPad, though it uses an external case rather than integrating inside the Apple slate. The unnamed prototype consists of a 2mm thick plastic case, and Murata says it will recharge the iPad just as quickly as the regular mains adapter would.
That's because the company has managed to increase its power output from a previous prototype, up to 10W like the standard iPad USB charger Apple supply with the iPad. A full re-juice takes 3-4hrs.
The stand itself is an angled platform, and the iPad can be recharged no matter which way it's stood. Murata won't be selling a commercial version direct, instead looking to provide the tech to third-parties such as case manufacturers; they expect the wireless charging module to be priced at 1,000 yen ($12) when bought in 100,000 unit quantities.
