The extension is very strong. I like USB ports for phones and other USB chargers - it's much more convenient than plugging a bunch of ports into USB ports. This is handy for travel because now you only need to carry one adapter with you and suddenly you have a ton of ports to use on the go. The cord is also quite long, so the outlet doesn't even have to be close to you. Also, the wire is very thick and strong, so even with many rides it doesn't look like it's going to break easily (it's just a little hard to fold when packing).
