Hi Rogelio,
Išve seen some really cool portable, lightweight, and folding solar cell
chargers that travelers take to remote locations off of the grid. With
these, you could charge up laptops, cameras, etc. You can get many sizes of
voltage outputs from these solar cell panels.
Take a look:

I'd be a first timer but still thinking about it. Wife isn't used to
this hobby of mine yet that requires me to dissapear for 4 days
somewhere in the middle of nowhere with a bunch of other "weirdos like
myself" (so she says, don't take it personal :-)
One concern... How do people who need power most of the time (and I mean
to operate laptops, mounts, etc. - leave aside basic needs) deal with
that? I've read the TAC wiki about batteries, and I noticed that when
this issue surfaces in the list many ppl go "here we go again" but I'm
still not sure what would be best for my needs (ok, a bit selfish but
before I can figure it out for someone else, i'd need to know what'd
suit me best, right?)
Since I mentioned "my" needs I'd spell it out: My basic need is life of
battery rather than power, and I wouldn't be using much, as I'd only
need to keep alive a 12v mount (EM400), a laptop (researching dc-dc
issues to avoid using the laptop's 120v converter), dew heater and a
120v plug to recharge my Canon's battery from time to time (I've got two
- I could recharge those at the inn I guess, not the "big" battery, as I
wouldn't be able to recharge it fully from one day to another). As far
as astro gear I think that'd be it. Did I mention I've never been at a
star party before?
