I travel alot and need this for my long flights. I had the phone charged at 100% before my flight. I turned on 'Airplane mode' and plugged in my external charger for a few hours until I wanted to play with it on the plane. It was down to 70%!!
I watched a 3 hour divx movie in TCPMP with the brightness as low as possible, volume all the way up (because I had to, it was a plane)and having it plugged into the external charger the whole time. The phone technically never died, but with about 20 minutes left in the movie, I kept on getting the battery low message (which interrupted my movie each time.) It was obvious the external battery charger was doing something...as the second I pulled the plug out, the phone immediately shut off from low battery.
About 30 minutes later, I decided to just try out PocketMusic and listen to some mp3s with the screen off and the battery charger still plugged in. No issues at all, actually after 2 hours of that, my battery was back up to 50% charged.
What is going on?

When you're watching the movie you're using the screen and using a lot of CPU so the phone gets really hot. Once it's hot, it won't charge the battery anymore basically to prevent the battery from blowing up.
Once the device cools down (Music, Screen Off demands much less power) it began to charge again.
There's nothing wrong with your external battery charger.
