This has saved my butt so many times in the short time I have had it. During my trip to Nashville I used this while on the road to keep my device charged up when the battery was getting low. I have a few portable batteries and I charge them all when I am going to be away from a power supply because you never know when you will need power.
When you hold it, it has some weight to it. Not so much that it is a burden but more that it is well made.
