Keep your power bank in your pocket. The Kodiak Mini USB Power Bank is highly useful and a super portable device you can carry anywhere on the go. What makes it one of the coolest power banks is the fact that it’s water, dust and shock resistant. So even if the weather is not by your side, you’ll have a 2600mAh rechargeable battery backup always waiting to be used in your pocket. Just connect it via the USB cable of your phone and give it some power whenever it runs out of juice. Just to keep up with the style quotient, you can get them in a range of gorgeous colors such as red, black, blue, camo and green.
