Back when HTC Thunderbolt launched we learned of a special battery cover for the device that’d allow you to charge its battery simply by setting it on a compatible mat. It looks like it may finally be on sale soon as the thing has appeared on Verizon’s site for $39.99. Pressing the “Buy Now” button doesn’t actually do anything yet, but we’re sure that won’t be the case for long. Now we just need to know if Verizon themselves will be providing an inductive charging mat. (Although we’re sure it’ll be compatible with Powermat’s option.) [via GottaBeMobile]
