Tripp Lite PV375 PV 375W 12V DC to AC Portable Inverter with DC Auto Power

$45.24 at Amazon.com....

TRIPPLITE PV150 150-Watt Power Inverter


For roughly 10% of the cost of the computer (or considerably less in the
case of my Dells) and the flexibility of being able to plug in basically
anything I would normally use (camera battery charger comes to mind) and
having the correct voltage, I'll spring for the extra $$$.

Sorry if this slightly non-satellite chatter:

Lots of folks are amazed how far Alaska is from anywhere.  Well, it is
2400-miles by road from Seattle to Anchorage (traveling over the Alaska
Hwy).  We traveled west from Pass Christian, MS (about 50-miles east of New
Orleans) on I-10 to southern California and then up I-5 to the Canadian
border.  If you look at a map of US roads there are no tangental roads from
the south to the NW so one will travel west then north then west then north,
whatever route you take.  It is something like 1800-miles from LA to the
Canadian border, alone.  We did a small detour over to the Oregon coast
which added a couple hundred miles.  The trip took 22-days.  We took one day
off in Gold Beach , OR for clothes washing and visiting with my wife's
mother whom she had not seen in ten years.  BTW I live on the same longitude
(151)as Hawaii (152).
photos of the van are here (scroll to bottom of page):

I spent about $10-15 on my wiring vs. $150+ for an AC inverter.  nuff said!
