XSories has introduced the 'Large Power CapXule', a storage case c32x23 cm in size, that can charge batteries on the go via a 2800mAh power bank.

It is able to charge 2 GoPro batteries at the same time (or one battery twice), before the CapXule needs to be recharged to repeat the process.

the 'on-board' power bank eliminates guesswork and ensures that you are fully loaded and ready to shoot.

The case comes in burgundy red and khaki green and has numerous compartments - including a dedicated GoPro slot.

It is priced at $79.99. More information can be found at the XSories website.
