PowerFilm R-28 28w Rollable Solar Panel Charger

This unique, light-weight, easy to store charger is used to charge our computers, cell phones, ipods, etc., that can be plugged in the to solar panel charger via an adapter. We just drape it over the car, picnic table, or lay it on the ground with our electronics in the shade while it charges. However, one cannot use the computer and charge it at the same time. It is strong enough to charge a boat battery, its original purpose. I liked it so well, I purchased another one from Amazon at a definite savings. [Wish I had bought my first one here!]

I have bought two of these already and am in the process of ordering a third .i have used it only once in late day january sun on flat ground in northern california it worked great. i am building a portable power grid for laptops etc. it can also charge car batteries. these rolls are light weight and weather proof as opposed to weather resistant which the foldable powerfilm product line claims. not sure how big a difference there is but weather proof sounds better. be sure to get an "RA-6 Daisy Chain Accessory" by power film it turns two panels into one.

also this is a good charge controller "HQRP Solar Power Controller 10Amp 150W with Digital LED Display"

i got it here on amazon

and to top it off i got an:

PST-YD100W 100 Watts Adjustable Output DC/DC Converter from powerstream. ps, i had to upgrade the 16v capacitors to 35v and 50v because the 16 volt capacitors blew.

Input 9-15 VDC Also AC 110-240VAC for home or car 4 to 5.5 amps

output 12V, 15V, 16V, 18V, 19V, 20V, 22V, 24V single output, user adjustable Also 5V1A USB

this is a beauty it comes with ac and dc plugs numerous barrel adapters for laptops

Price $39.50

then i added this "Energizer XP18000 Universal AC Adapter with External Battery for Laptops, Netbooks, and More "

it must have 19v at 3.42 amps to charge so i am getting a third panel and a second daisy chain to make it work.

3 rollable 28 watt panels will put out 15.4 volts at 5.4 amps or 84 watts under best conditions

it boils down to a portable power grid a backpacker could take for around 8 lbs which i find acceptable if your laptop etc isnt too heavy.

ps the fact that many of these are sold on amazon with no negative reviews speaks strongly in favor of this product

This is a nifty little item, and we purchased one to use when we're out at the sports field with my kids.

One of these unrolled on the top of a collapsable shade canopy (oriented southward), and it gives us the ability to power 2-3 small 12V fans. It keeps the air moving, and everybody cooled/shaded/happy. You can even charge up your cell phone (the larger panel puts out almost 2A of current at 15VDC.

Roll it up after the game, and put it back in the box for the next weekend.
