A little while back there was a recommended product discussion and someone recommended a portable power pack for mobile phones, etc... I can't find the thread anymore. If the that poster sees this, can you mention it again? Will delete this afterwards. Thanks....
You can charge 2 devices at once. It has a 1A and 2.1A charging. You can charge a number of times.
It works great and it's durable.

If you dont need that big of a pack they also have smaller ones that will work well too, I think they are all priced between 20-40 dollars. I have the 40 dollar one so i can only comment specifically on that one but its great. It has all the cables you need unless you have an iphone you will have to buy an extra lightning cable. I got the .5 meter lightning cable to use with it so its not nearly as long and goes into my pocket easily. I really recommend it, its great to have. If you have an android phone the cables it comes with are all you need
Just search powergen charger on amazon and they will come up. I've bought a bunch of powergen products and they all work very well
