If green is in for you, then you will like the Solio Magnesium Edition. This universal charger uses solar energy to supply power for your gadgets. And if the sun isn’t in sight, you can always use the outlet with the included adapter. The Solio is a bit chunky to look at, though the reviewer noted that it fits your pants’ pockets nicely. You can easily fold the Solio when not in use but the panels are still exposed. It comes with a mini-USB cable to attach it to devices that accepts that connection. Another USB cable is available to hold special tips to make it compatible with certain kinds of phones and portable gaming systems. The speed of charging depends on the amount of sunlight available: cloudy days or indirect sunlight will charge it slowly. The Magnesium edition stores more watts than its predecessors and actual tests came close to their claim of providing nearly 50 minutes of MP3 playback for every hour of solar power. The biggest drawback with the Solio is its $160 price tag. If your aim is to go green and you have the cash, the Solio Magnesium Edition is an excellent charger.
