Solar Chargers

i think this is where this belongs but everyone... i been looking for a good solar charger (obviously good), charge devices fast, holds alot of power, multiple slots to charge multiple devices, and atleast $50 online... or atleast $130 in stores (ya, i doint have much money), i thought i found good ones but i dont know whats actually good... so hope someone here can help me

if it helps, devices i have i can charge are... hp touch pad, psp, smartphones, ps3 controllers, ect.    a laptop too but i realize or would understand that theres not really a solar charger for that (that ones not to important)

Have you checked your local hardware store yet?

Neat project

I just created an instructable project for a solar charger that can help you out. It's based on my Kickstarter project that was launched recently: http://www.instructables.com/id/Solar-Powered-Sold...

I don't think that cheaper low-cost materials will provide enough power for you, unless you are willing to use car batteries and big cheap solar panels, but it wouldn't be as portable or as easy to use.

So I think your wondering where to start with a solar setup on a budget. So was I.
First you need to figure out how you'll be using it? Are you living off grid and need to charge this stuff every day? Or do you need to charge this stuff for a 2-3 day weekend camping once a month? Two way different scenarios. If this is an off grid, daily thing, $150 might not be enough. You also need to consider that it could rain for 3 days in a row. If it's an off grid thing I'd put more money in the solar. If its a weekend thing I'd put more money into the battery.
I'd look locally for a deep cycle marine battery or SLA scooter batteries if you need to be more mobile.
You can get cheap-ish 20 watt panels from eBay and I noticed Home Depot is selling panels now too. 20 watts would be the minimum I'd say.
Then you want a charge controller. I got a cheaper one on eBay for about $20.
As with everything you get what you pay for. Once you get all that I'd set it up in your back yard and see how it works for a few days. You'll soon see where you need to fine tune your setup. If its a weekend thing maybe you should rethink it and just buy a nice battery? You can always buy more panels and more batteries so maybe a higher quality charge controller is a better idea? The basics are the panel, battery and charge controller. You can't just hook up a panel to your phone to the battery is a must. The other basics are the placement, angle and wiring. Spending $30 on wire to get the panel 50 feet away in the full sun can be the smartest thing you do. That alone can make up for lower quality batteries or solar panels. You could spend $400 on panels that only get 4 hours of sun or you could pay $200 +$30 on wire and get the same result. Ya know.
I'd guess you have a 12v charger for your phone and tablet but might need to look at power inverters as well. Again. A quality Pure Sine inverter is best but try to avoid inverters as they can be pretty inefficient with the cheaper ones.
Ps - always make sure your using a few inline fuses. Low amp ones. If something gets crossed somehow you don't want to fry everything and then burn your house down. DC is just as dangerous as 110 results wise.
1 technique
use solar power in electrolysing water instead using it for other work
then after h2o is is separated int h2 & 0 use h2 again combine , their will be energy released
use this energy by converting it into electrical
