Apple has announced a Product Red version of its Smart Battery Case for the iPhone 7. One of the few acceptable reasons to get the hump-back case, Apple will donate a portion of the proceeds from the case towards fighting AIDS in Africa.
Other than that, it's nothing more than a red version of the case already available in either black or white. Price is the same - $99 in the US. It's still not listed on the Apple website, but that'll probably change in the coming days. Meanwhile, you can scroll through the other Product Red items.
