I bought this to carry in my messenger bag so I could use it at worked, when needed. While it worked the first couple of times, it has started to be a pain. When I try to charge it I have to wiggle the connection and then place the phone in odd positions so it will stay connected to charge. After several hours of charging, the phone still wasn't fully charged. I know it's not my phone because my home charger does exactly what it is supposed to do.
