Great travel accessory
I received 2 of these when I was implanted (cochlear implant).  I have used them for my hearing aids and CI equipment for 6 years and they perform very well.  They are lightweight (this is an important characteristic for travel, when I am already forced to carry chargers and extra batteries for the implant processors).  They work in humid environments.  They can easily be recharged if you have access to an oven.  They are good for storing spare equipment when not traveling, as well.
