Solar battery chargers

[sleepnasta]

Anyone have one? Heard of them? What are your thought/ reviews? I'm thinking about getting one.

Someone posted about it last week. They bought a 13W unit (they sell for less than $100).

If your looking for one that can power your device for a few days of power outages, you will need at least 135w panel. That will be about 5 foot x 2 foot. Then you need a solar charger device to properly charge the battery.

I would think a 45 Watt solar panel would keep your cpap powered up with a good battery as long as you don't use your humidifier. I made it twice in the wilderness for 8-9 days with an 18 amp battery and two 12 watt folding solar panels. At the end of my trip my battery votage was getting low, if I had a 45 watt solar panel I think I would of had no problem.

If it's summer so you get more hours of daylight, if it's not cloudy for a few days, if there are no trees shading it for part of the day, if you have the solar panel set up all day long, and aren't carrying it to a new camping site, if you don't use the heated humidifier, if you don't have a lot of leaks, etc.

It takes a lot of investigation and planning to make a solar installation work.

Sleepnasta, why do you want one? Full time usage, power outages, repeat of Sandy, where do you live, home usage or travel, etc.?

It was late October In Frank Church Wildernes, Idaho. This year it was cloudy 5 out of 8 days and one day it rained all day. The sun does not hit the area of the basin that I had my solar panels set up until 9:30 or 10:00. I left the panels in the basin and would carry my battery out just before day light and retreive it after dark. If you were hiking and or moving camp then no it would not work. I have not used a humidifier in three years, don't need it.
