Can I use my Joovv device in a Sauna?

For electrical safety reasons, none of the Joovv devices should be used in a sauna. Specifically, Joovv Generation 2.0 devices should not operate or be stored in temperatures that exceed 84°F, and Joovv Generation 3.0 devices should not operate in or be stored in temperatures that exceed 104°F. This includes Saunas.
