Safeguard your iPhone 6 or 6 Plus with the bulletproof ZeroShock case. The durable and protective case is also hiding a not-so-little secret – a massive 4,600 mAh removable battery, offering an incredible 250% extra charge for your iPhone 6 and 300% for iPhone 6 Plus (6,100 mAh).

The ZeroShock includes two layers of protection for your phone, with a soft rubber shell slotting inside a solid plastic, giving you OtterBox-like protection with a huge battery built in. The built in flaps protect your ports from liquid damage and that linty fluff that builds up in your pocket. The package also includes a belt holder which doubles as a handy kickstand for hands free viewing.

As well as keeping your device as good as new, the removable battery pack ensures you won’t run out of power for a long, long time. Charge the battery slot in your iPhone and you should have enough power to keep even the most active users going. You can keep track of how much charging power is left with the built in LED indicator.

The unit ships free in the US at just $45 for iPhone 6 and $51 for 6 Plus, saving a healthy $15 and $19 respectively off the list price. This high-quality unit should go the distance, but with a year-long manufacturers guarantee, you get some peace of mind too.
