Bests & Worsts Reviews from Amazon

I have been trying out different solar USB chargers for over a year and the sCharger-5 is the best so far! It is thin, convenient, lightweight, has a built-in universal USB port for any device, and folds up to fit in a small bag or large pocket. You have to understand that Solar power does fluctuate throughout the day and is most powerful between 11am and 2pm, so you need a very powerful charger like this one that can charge up your phone or any other USB device in a few hours, especially if there are lots of trees around you and the sun only shines through briefly. I got mine about a year ago and it still keeps working rain, shine, or falling off my bicycle! The funny thing is that some devices do have some trouble charging directly from solar energy, but that is not the fault of the sCharger-5. For example, some USB batteries and even the iPhone show some error messages, but this is because the designer of the device was too stupid to allow the electrical current to throttle efficiently as the solar power changes throughout the day. The iPhone in particular requires a special circuit to charge because Steve Jobs wants to license the technology and steal money from anyone who wants to make an iPhone accessory. The sCharger-5 compensates for this by resetting the solar power every few minutes and in effect unplugging and plugging back in the solar panel automatically in order to return the device to normal charging and charge the iPhone at record speeds! However, recently, battery and phone designers are becoming more advanced to take advantage of variable current from the sun and now they are able to accept any power from the sCharger-5 at even faster rates. This is actually a happy coincidence in design because all USB ports do not have the same power output. Your laptop from 4-years ago may have 2.5 Watt USB ports while the new 2011 Macbook Pros have 10 Watt USB ports. Because of this trend, designers had to come up with new ways to accept various USB power from all the different laptops and desktops and by chance, the new devices they design are actually more solar friendly. So in conclusion, the sCharger-5 is way ahead of its time and will be around forever while the devices that plug into it are evolving to take advantage of the huge solar charging power output of this panel.
