As anyone who has ever used an action camera will know, they have a nasty tendency of chewing through batteries just when you're in the worst possible situation to recharge them, whether that's halfway up a mountain or at the beach. Polar Pro is attempting to address this issue with the launch of the PowerVault, a GoPro carrying case which can charge a GoPro battery five times thanks to its own built-in battery.
At first glance the Polar Pro PowerVault looks like any other device case. It features a water-resistant ballistic nylon exterior along with waterproof zippers to help provide protection against water or snow. Inside the protection continues with a laser-cut padded interior offering the chance to carry one GoPro camera along with additional cords and accessories.

However, it's the battery slots in the corner of the case which is where the appeal of the PowerVault lies. Four battery slots allow for the charging of two GoPro Hero3/3+ or two GoPro Hero4 batteries. An embedded 5,200 mAh battery is able to fully charge a GoPro battery in 1.5 hours, or get it to 70 percent charge in 45 minutes.
It should be noted that users can only charge either Hero3/3+ or Hero4 batteries at any one time. However, the PowerVault can also be used to charge other devices such as smartphones thanks to the inclusion of a USB port. The case itself measures 33 x 25 x 5 cm (13 x 10 x 2 in) and weighs 425 g (15 oz).
The Polar Pro PowerVault is available now for US$100.
