I've had my K2 for two years now and in the last couple of months I started noticing small cracks in the casing on the charger. I have taken excellent care of my equipment and couldn't figure out what happened. So I got some electrical tape and just taped around the small cracks. Well, it has continuously gotten worse and it is flaking off big time. Yesterday I picked my charger up and a large portion of the casing just fell off exposing the wire. What is up with that?? I hate to spend another $20 bucks for a charger and was wondering if anyone else is using a compatible charger (cheaper) that won't harm the Kindle.
