The K3 is a small package item that can fit in any suitcase or could be clipped on to a backpack for travel. The K3 can be charged from the sun, wind or an electrical outlet. It is designed to be used standing up, lying down or hung. There is a button which will illuminate the charge lights so you can see how much juice is left.
I tested the K3 in the bright sun and directly in front of an air conditioner. For three weeks straight the K3 was charging my devices. If you are camping out or hiking I would recommend having it around because it could become a life saver.
