Jiffy Esteam Travel Steamer
This produces about 15 minutes of steam on the eight ounce reservoir of water it holds but that should be enough for travel since you would generally just be doing a quick steam to a shirt or something. It automatically shuts off when the water runs out so you do not need to worry about steamer burn out due to an empty tank and no steam.
It gets wrinkles out well and I always pack this when I travel so I can still have wrinkle free shirts for meetings. It is a little big for packing on carry on for a plane but I do not fly much but go by car most places so this works for me. It heats up very fast and works great. It comes in black or pink though neither model is very pretty to look at. It works with normal tap water and does not need salt or other additives to work. It has a wide mouth so covers a lot of shirt with steam in each pass.
The long cord is especially good for use in hotels where you may have an inconvenient outlet location. It is six hundred watts of power in this personal clothes steamer. No need for an iron and board, which would be very difficult to travel with. It is great or a quick dewrinkling at the office and is fairly light. It is fairly light so not a problem to carry or use though the handle could be more ergonomically friendly; it is not to bad though.
The steamer does not heat up in your hand, which is a nice touch, so you do not need to worry about getting burned. I have never had this get clogged. There is no pump or internal water tubes to have to worry about and fiddle with.
