Bests & Worsts Reviews from Amazon

To start: I did not receive this product for free or at a discount. I'm writing a review because I've been really happy with this solar charger. I've had the Nekteck 20W Solar Charger with 2 USB Ports for about 5 months. It is well-made and folds up very conveniently. But what I'm especially impressed with is its performance. It quickly charges my iPhone in bright sun -- it's quite comparable to being plugged into a wall outlet. It also works well when cloudy. It takes about 2 to 3 times as long to charge my phone on a totally overcast day ("bright clouds"). And I've been especially surprised to find that it will actually charge devices quite effectively through a window that gets a lot of afternoon sun. I've found it easiest to use the Nekteck solar charger to charge a separate power pack, and then use the power pack to charge your phone, tablet, etc. Overall, I'm a very satisfied customer. I can honestly say I didn't expect it to work as well in sub-optimal conditions as it does!
