Hi Thomas--

For how many days in a row unattended?

For one night, might be as simple as slipping the Tekkeon battery in
a old mitten and wrapping that up with a couple of chemical hand
warmers with some fabric.  Slip the Edirol in the other mitten and
put both units inside of an air-tight, insulated "bag."  There are
commercial cooler bags with an aluminized fabric layer. If you had a
way to pre-heat it, a small soapstone would  also supply all the heat
you need for overnight. n

Or, 10 degrees isn't that cold, you could probably get by with a 50%
higher capacity battery or parallel wire two Tekkeon's.

For days at a time, if you want to get fancy, here's a company that
makes battery-powered heaters: Rob D.
