Review: A Thoughtfully Executed Small Package - After researching WUSH bag requirements, I chose the Voltaic Systems Backpack because of its solar backpack charger and removable battery pack. Upon receipt, I found the bag exceptionally designed and smartly executed, with ample storage compartments in a compact size. I highly recommend this bag for those interested in packing for an immediate emergency evacuation lasting 2-3 days. If you need a Go Bag, seek something larger.
Review: A great purchase. - I bought this for my daughters travels in the US and abroad. We have used it as a carry on, and it saved us soooo many times we needed a phone or computer charge. Went through security with no problems. A great purchase.

### ⭐⭐⭐⭐⭐ One of my best purchases ever
*by S***E on January 7, 2015*

One of my best purchases ever, love it!, I travel a lot and this backpack is always with me. The charging process is a charm and it manage to charge my Galaxy Note & my cell phone in a blast, it also works with small cameras. Be aware that eventually battery will need to be replaced though and it's certantly not enough to charge a laptop. Also the backpack is very confortable to use, it distribute the weight in an excellent way (i has some problem at my lower back after an accident so i can tell the difference with other backpacks inmediately) Also, an defenitely a plus, the fabric of this small wonder is waterproof and made with recycled soda bottles.
