Just smoked a rechargeable MP3 player by attempting to

 power it up with what appeared to be a cigar lighter to

 USB power port power adapter.



 After the smoke cleared, I opened the critter up to find

 that somebody thought it was a good idea to use this

 ubiquitous connector for some kind of 12V application

 too.

 Just a heads-up . . . when in doubt check it out. Some electro-

 whizzies one might wish to power up from such a device could be a

 whole lot more expensive than my $29 mp3 player!
