I rigged up a small 6v lead-acid battery on an external cord for
cold-weather operations. I figured I can leave the external battery under
my coat to keep it warm, and the 6.5V of a fully-charged battery matches
the power supply voltage.
Now... if only it would get cold enough to need it here without
going back to Alaska...
