I am embarking on a journey soon, and if things proceed as per usual I will somehow get stuck in the Dallas airport for numerous unanticipated hours. At which point I will wish I had a hot water travel shower. But, due to obnoxiously stringent carry-on luggage restrictions, I won't have a hot water travel shower, and therefore no means of cleansing myself of Texas airport stench. I will be stranded alone, nothing in my possession but the small backpack that fits under the seat in front of me, which will contain my computer and 750 Twix bars for bartering with the peoples of my final destination.
The ZODI Outback Gear Hot Tap Travel Shower delivers instant hotness and wetness from a small box. A stainless steel burner ignites matchless, at the push of a button, and streams an unlimited supply of hot water in seconds. I mean, obviously it doesn't materialize the flow of water itself from thin air and your utterance of the magic words, but its pump and hose system can route washing liquids directly from lakes and streams, or its 4-gallon holding tank can maintain enough of a stock supply for a 10-minute shower when a continuous source isn't available.
ZODI's Hot Tap Travel Shower attaches to a 16.4-ounce propane cylinder, or 5-gallon propane tank, and also includes an 8-foot hose with showerhead in the set. A gas valve can adjust water temperature up to 100 degrees F.
