As long as you check it in baggage. No airport security is going to allow a device of unknown composition full of electrical wires and a control circuit past the security checkpoint. I still remember the case of the Chinese inventor who arrived in the US with his invention -- electrically heated shoes -- on his way to a meeting with a venture capital firm. The TSA confiscated his shoes, determined that it was an explosive device (thanks to the chinese batteries it used) and detonated it on the airport tarmac at SFO. They take those electrical wires seriously!

What you can use if you are cold is a space blanket (reflective foil). Very light and quite effective on planes as it reflects your body heat.
