Question is in the title. I am hoping to uncover some possible self modifications that others have thought about that may be accomplished by a do-it-yourself-er. For me, I am seriously considering modifying my carry-on to have a surge protected power strip mounted flush to the side wall of my hard shell spinner with a retractable 10-20 ft cord. I have a power strip that I pack today, but think the side wall under the lining or between the spinner wheels would make it more accessible and use up space in the bag better. Nothing like seeing that the only available plugs in the airport are inaccessible because the seats near them are all taken. With this mod, I could plug my stuff into the side of my carry-on spinner and pull out the self reeling cord, like in some vacuum cleaners, and say pardon me, may I plug this in behind you. Bam!

Obviously I could pull an extension cord and a the a power strip out of my bag, but that is clumsy.

FYI: I usually travel with my two kids, so the multi-plug strip works best for us.

Only question is will TSA be bothered by that mod? Probably/hoping not.
