I need 5 VDC to power a mobile experimental circuit. Is there a problem in using a car cell phone charger to do this? It's basically a DC-to-DC converter. How would the charger circuit live on a permanent basis? Is there a more elegant solution? I understand most chargers use an IC to limit ultimate current thus protecting sensitive circuits. My old cell phone required 5V 1A max (according to the charger jack on the phone) so I figured that unit's cell phone charger might work.

Thanks for any info you have.
