How to Turn Your Backpack Into A Solar Charger
It sucks to be out and about with a dead cell phone or MP3 player. That’s where Solarrific, a backpack solar panel, comes in. Not only will it charge all your portable electronics and personal communication devices, the makers say it will do so in record time – 2 to 3 hours for a standard phone operating on a 3.7V 1020mAh lithium battery, according to the maker.
At 5 watts and roughly 12 inches long, 8.5 inches wide and about three quarters of an inch deep, the Solarrific’s crystalline silicon solar panel comprises what is still the most efficient material for generating solar photovoltaic (PV) power. And even though it is lightweight, it still has enough charging power to bring your favorites – a digital camera, an iPod, a travel lamp, a Palm Pilot or even a GPS system – back to life when you’ve neglected them.
Attaching to your favorite backpack (or even fanny pack) with straps, the Solarrific also attaches to any house or car window with suction cups. With none of the above, it stands on its own, soaking up rays and giving them back to your favorite portable electronics via any one of 6 adapters or a USB charging cable that hooks directly to your portable laptop. Backed by a one-year warranty, the Solarrific ranks right up there with other portable solar chargers we have reviewed (and explained), including the whimsical duo called Kahuolfummi and Miyazaki (battery and solar panel).
