You’re out in the middle of nowhere and your PDA batteries die, what do you do? Why whip out your iSun portable solar charger of course. This elegantly designed little doozy will charge up phones, PDAs and other small gadgets (not laptops!) and costs $80.00 or so.

It also comes with suckers to stick it to the car window. Not sure how long it takes to charge up a depleted battery though, especially if you happen to live in….ahem….sunny London.
