Just responding to say that I finally got it to work after trying several USB ports and computers. After a few hours it charged fine and I haven't had any problems with it since, I'm honestly really enjoying it and feel that it's a quality device. I'm blaming the problem here on my fault USB ports, while I haven't had too many issues with charging on them there have been some.
Anyway, now that I"ve found a USB port that works, problem solved for me
