Overview waterproof external battery
Not so long ago came across an awesome novelty, waterproof and pylezaschischёnny battery from the company Photive.
Model Photive Bolt has a capacity of 9000 mAh, 2 usb output for charging devices that clip to hang it on a nail in the garage (it’s brutal battery) and shining lantern. And also has a very impressive view. This device can be used in order to samoborony, this is still a brick.
Price on Amazon is only $ 40, probably because the discount. For a hundred and not a pity to give.
