Review: The Aircharge Wireless Charging Case for the iPhone 6 is hard to resist - Computerworld
Is it time for wireless charging. IKEA recently announced a line of furniture with embedded Qi wireless chargers. For its part, Starbucks went with the Powermat specification for the wireless chargers embedded in its tables, so your Aircharge wireless charging case won't power up your iPhone as you sip your iced caramel macchiato. Among other issues, there's a standards war going on between three major wireless charging standard groups. The Qi standard is highly efficient, and you're not likely to see any difference in charging time between a direct-plug electrical cord and this wireless charging case. Unfortunately, one of the drawbacks of the Qi standard, and products like the Aircharge iPhone 6 case that uses it, is that the technology is based on magnetic inductive charging. Inductive charging, as opposed to magnetic resonance or "loosely coupled" charging, requires relatively precise placement of the phone directly against charging pad for it to work. The sweet spot isn't hard to find -- it's right smack in the middle of the Aircharge case, but if you move the case too far in one direction or another, the charging connection is lost.
