Large voltage transformer (3000W) ok for carry-on?

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?

I'd say that so long as you fit within the regs you'll be OK. Watch packed dimensions as well as weight

Can't see any issue. I regularly carry on over 50 pounds of camera gear and never had an issue.

Thanks guys. I'll give it a go. I guess it just seemed like something that would raise some questions since it's a heavy metal box filled with wires...but it's obviously harmless so I'm probably just over-thinking it.

It will most likely get a secondary search after going through x-ray. Once they look at it and realize it is not a container of something dangerous they should allow it.

Did you try it? I am considering taking a very similar item as a carry-on and wondered if any red flags were raised.

It depends entirely what the airline is.

Lufthansa are well known for being very strict about the weight of hand luggage. Quite a few people have had rants here about this.
