Q&A: Home-made solar cell phone charger difficulties?

by windygig

Hey I recently built for myself a solar-powered cell phone charger for my Palm Pre by this these plans. http://www.instructables.com/id/Solar-Powered-Cell-Phone-Charger/

The solar cell is a 6V 50mA and the DC outlet is 12V. My conundrum is when I plus the phone into the charger cable, it will pup up that it is charging but then the entire UI becomes extremely sluggish, making taps on the screen take numerous seconds to register in anticipation of the screens settles into an entirely unresponsive state. Removing it from the charger does not fix this and and I end up having to pull the battery and do a hard restart.

Any thoughts why this might happen?
