While I was out the other day I came across a couple of solutions for charging portable devices, like iPods & media players, iPhones and other mobile phones, GPS navigation units or portable gaming devices using the energy of the sun. The two models I saw in the store were the Solio Universal Hybrid Solar Charger and the Solio H1000 Hybrid Battery Charger.

Of the two, the H1000 was perhaps the most appealing to me, simply because I’m not such a big fan of the fan out operation on the other model. Both have an internal battery that is charged by the solar panel, and can then be used to charge your external device. That means you can leave the charger in a sunny place all day, and then top up your phone from it overnight. And using solar power instead of leaving the phone’s AC charger plugged in all day, reduces the phantom power drain too (unplugging that AC adapter when you’re not using will help there too).
