It really sucks when you need to charge my phone or when I need a fridge. I used to keep an Igloo cooler and have my lunch and dinner in there. I do the 72 hour/4 day session with my best friends autistic kid to get him really liking the chamber. Many parents try to get their Autistic children to go in the hyperbaric chamber and laying in there is like Time Out. They are telling them to be quiet and relax. I am telling them to breathe. I am an adult with autism myself and I know what it is like to have sensory issues and get antsy in the chamber and "get me out of there".
When I go over to the parents home they see how the kid doesn't even want to leave. Kids can't enough of my vibro accoustic mat. I have a custom mat with 4 high end subwoofer transducers, not just the 2 factory stock low wattage ones. The chamber is rocking and rolling. It is not loud since we feel the bass, not loud and damaging our ears. I also have a Biomat under the hyperbaric chamber. We have raw coconut pies, first time durian experiences, and we have all the 5 signal foods. We get all 5 food signals so there are no cravings of any foods of any sort. Wild honey and brine free salt always does the trick. We watch movies (even ones that are not out yet on DVD). Parents are watching in from the windows and having just as much fun as we are. Once the kids associate the chamber with fun and their own private get away, you don't have to "try" to get them in the chamber. It is not a good experience if not introduced right.
None of the factory standard chambers I know of come with electricity ports. Unless requesting a hole punched in at the time of purchase (there is an extra fee for this) people will have to send their chambers in to get this done. It only costs about 100 dollars to do it. There is usually a wait list to get this done on chambers sent in that don't have the port. It takes about 2 to 3 weeks for the entire shipment process when getting this added to the chamber.
If you need a port on your chamber, let me know on my Hyperbaric chamber quiz. When I wake up in the morning in the morning in my chamber, I have my Vitamix ready to go. For taller people, having the 10 foot option length gives so much room for nearly anything I need to stay in the chamber for a long time.
