What kind of lamp are we talking about?

I will not look at anything in dropbox because I do not trust the site not to try to steal as much data about me as possible.

Sorry, I missed the bit about trying other things.
Have you tried an incandescent lamp or other RESISTIVE load? A LED lamp and a charger are electrically similar to each other at the input.
