I have a rechargeable USB electric 'arc' lighter. It a similar model to the one shown here (sorry for the ebay link, best I can find and I can't find a picture of it working). When activated it creates an electrical arc between two points -- it's not like the 'element' electrical lighters where a heating element gets hot (i.e. the old car lighters).
Does anyone know if this is likely to get confiscated by airport security? I know some lighters are supposed to be allowed but I've often had seen them confiscated anyway (particularly in China). But they were all gas/lighter fluid based lighters so this is different. Although it does seem to come close to being a 'torch' lighter which is explicitly banned (and from the outside it does resemble a torch type lighter).
I suspect that security will probably confiscate it anyway, if they're confiscating lighters. And I know it's not a good idea to argue. But perhaps someone has traveled with one of these before or can find some official documentation that I cannot.
