Apparently, Vita chargers suddenly not working is fairly common (and as I'm a new Vita user, I learned that a little behind the curve). Playing the Vita is a nice, relaxing break from the hectic, stressful days, but if it won't charge, I can't have that break. This one works really well, and I'd recommend going to Best Buy for things like this, as they'll actually test the charger to make sure it works before selling it to you (you probably have to ask, but they're super friendly and the quality of service is commendable). It'd be nice if it allowed computer backups and transfer, but as the Vita was having issues doing so by WiFi as well, I'm going to guess it's something wrong with my Vita and/or the Sony program on the computers I tested it on, rather than with the charger itself. I ended up going to Best Buy because it seemed a good alternative to Game Stop, which also was said to allow charger testing, but Best Buy has better and less pushy customer service. Also, compared to the chargers I was looking at on Amazon, I'm very happy with the price!
