Raise your hand if your iPhone has run out of juice at the worst possible time? Yeah, I’m sure that’s most of you. Certainly me. That’s why I have a battery pack case for my iPhone. While it’s good, it does have a little flaw—I still need to plug it in to charge.
Now a solar pack can help eliminate some of this need. No, not all, but let’s say, a lot. The Monster Watts case acts not just as a batter pack, but it has solar panels so you can recharge your phone wherever the Sun shines!
Since I got the Changers solar charger to test, I haven’t plugged a USB-chargeable device into anything else (with the exception of my iPad). Changers comes as a kit containing a solar panel and a battery pack, along with a a bag of tips that fit most cellphones and gadgets. But this description doesn’t do justice to what is a rather excellent and useful device.
The iPhone is a phenomenal tool for a bit of tromping about in the bush; navigation, stargazing, photographing/filming and even staying alive can all be accomplished with the help of the little gadget. That is, if it’s got any juice left.
Solio’s Rocsta ($80) — a solar panel mated to a thin slab of a battery in a sleek, flat, user-friendly housing — seems to have been created with a nod to minimalist adventurous types who want a rugged, no-fuss solar charger aong on their next Iditarod or photo shoot for National Geographic.
