In a note to backers, which was first discovered by Wired, Pop says Apple wouldn't allow the project to use the Lightning charger in the same device as a USB charger or even Apple's own 30-pin charger for older iPhones and iPads.
The Pop project raised more than $139,000 and the company promises to refund every penny to backers. It's even setting up a special website to do so because Kickstarter doesn't make it easy enough to issue refunds for canceled projects. Pop is also taking a ~$11,000 loss due to credit card fees and the 5% cut Kickstarter takes.
Pop could've gone ahead with the project without the Lightning charger, but the note says the company didn't want to ship an incomplete product.
UPDATE: Apple tells Ars Technica that it has reversed its decision regarding pairing the old 30-pin Apple charger with the new Lightning charger in the same device. However, it's still unclear if Pop will be able to get the project moving again.
