In the last minute attempt to cover my iPhone5 power needs on a backpacking trip I was lent an Efreesia Duo. I had spent some time looking at solar chargers and a few battery back ups– none of them had very good reviews or they seemed to be quite heavy and/or cumbersome. At first glance the Duo looks like a smart phone, it is roughly the same dimensions as an iPhone 5 but a bit lighter. I charged it via micro USB and headed out to the mountains of New Mexico at the Boy Scout high adventure camp Philmont.
A few people in our party had solar chargers and were constantly scurrying around trying to charge up the batteries attached to the solar cells. I trusted in the Duo and was not let down– over 11 days I got 3 full charges out of the Duo. The 4 blue lights gave me an idea of the power left in the unit. At the time of my trip, I had honestly no idea what this thing costs but come to find out that it has a price point below $50! I would not hesitate to pick one up just to have on hand for unexpected needs, after having the chance to try it out. I would prefer that it had a lightning (the new iPhone adapter) built in as it does instead of USB and Micro USB, or maybe there could be an Apple specific unit. Two thumbs up on what appears to be a solid piece of engineering and design.
