Hi, I found a nice small portable solar rechargeable camping 6 led light, cheap. I think it would make a cheap present for some of the guys at work. I would like to buy 6 or 8 of them. I already bought one. I was playing around with it and i thought it was kinda cool, bright and useful. The question I have is if I can I bring back them on the plane with me. I am worry that they will will be taken away from me when I check in because of the batteries that they have in them. Any ideas? Thanks. Danb
