MacRumors Giveaway: Win a PowerShadow iPhone Battery Case from Spyder

For this week's giveaway, we've teamed up with Spyder to give three MacRumors winners a chance to win a PowerShadow battery case for the iPhone 6, 6s, 6 Plus, or 6s Plus.

Described as the "world's thinnest" battery case for Apple's latest iPhones, the $99 PowerShadow case measures in at 14.5mm thick and includes a 2,750 mAh battery for the iPhone 6/6s version and a 3,500 mAh battery for the iPhone 6/6s Plus version.

In addition to adding extra battery life to an iPhone, the PowerShadow case is made of rubber-coated impact-resistant carbonate to protect the device from drops and it improves water resistance with a unibody design and port plugs. It also has built-in antimicrobial protection and a lip around the edge protects the iPhone's screen when placed face down.

The PowerShadow case charges through micro-USB, but with an optional PowerShadow Dock ($49.99) the iPhone and the case can be charged at the same time without the need to remove the case from the phone.

Spyder offers the PowerShadow case for the iPhone 6/6s in Black, Titanium, Champagne, and White, while the iPhone 6/6s Plus version is available in Black and Titanium. Both cases are priced at $99, but three MacRumors readers will win a Spyder PowerShadow case at no cost.
