I'm an ex-pat American living in Switzerland....and I need to replace my large voltage transformer. I am traveling from the U.S. back home and to save money and baggage space, I figured I'd throw the new transformer, which is really quite heavy (25lbs or so) into my carry-on and save some checked baggage capacity for other items. I figure since they rarely weigh carry-ons for compliance, I might be able to get away with this approach.
Has anyone ever tried to fly with something like this? I can't find any explicit prohibitions against such an item on the TSA website, but it seems like a giant device like that might draw some attention (i.e. red-flags) going through the scanners. Thoughts?
