Ideal for camping or emergency power outages, the
Sun Power Port is a portable generator that when used
to its full potential will pay for itself in less than two years.
In one day of full sunshine, the solar panel easily charges
the 12 volt (standard automobile) battery. An inverter
changes the DC current to AC. From there the electrical energy
is easily accessible to most standard 110 volt small
appliances used in North America. What are the advantages of a solar generator? If you don't know, check out sunpowerport.com. The featured generator will run most small electrical appliances. It is great for camping or emergency backup. No noise. No fumes. For more details see http://www.sunpowerport.com

So how many Kwh do you get from one full sun exposed day?

Is this a solar only device or can I charge it with other methods: plug in, wind, cycle power etc?

That looks pretty cool for the camper but I can't see any details on the site that show the whole product. Who makes this thing anyway?

I want one of these, but I don't know if it would work for me. I would have to put it outside to charge and then bring it back in for a few hours of use. I think its too complex. I still want one. I can be a bit of a technofile. Thanks for bringing our attention to this idea.

So with this apparatus, how long will the panel last and how long does the battery last, especially if you aren't using it all the time, for camping and other outdoor activities only?
