As part of Madison Square Garden's renovations, Powermat is installing 559 wireless charging spots throughout the arena. Shown here is a Powermat iPhone 4S case featuring the Knicks team logo. In case consumers don't have a Powermat case, they will be conveniently sold at the arena.
An iPhone 4S with a Knicks Powermat case sits next to one of the hundreds of charging spots littered throughout the arena. The cover has to touch the spot, and they have to align correctly before the charge begins.
Powermat offers several products, including replacement back covers for Android phones with removable covers, cases for the iPhone or Galaxy S3, charging mats, and a backup battery than can be thrown on the mat for a quick charge.
Because of compatibility conflicts, only phones using Powermat's cases or back covers will work with the charging stations. Other phones that have been announced with built-in charging, including the Droid DNA and Lumia 920, won't work here.
