iSun deals

I walked in to Radio Shack today to buy an adapter, and lo and behold, here's the very same iSun solar power unit for $39.97. I can't find it at their web site, but the rep I talked to made it sound like they'd had the unit for a while. This wasn't a sale, just regular price.

Also, the unit includes an adapter to let you plug in a car-charging device. (That is, something you charge in your car like a phone, not something that charges your car.) So if you already have a car-charger for your phone/iPod, you won't have to jingle with the USB hootenanny to charge your batteries from the sun. (Jingle if you want to.)

Not to belittle his effort, but didn't his come with this adapter??? :blink:
