I rate this product five stars after my testing of it, which is written below. This product exceeded my expectations. I prefer this product over the PowerMonkey Extreme battery. The RAVPower 15,000 mAh Deluxe Series External Battery is a good size to carry in my messenger bag. It is heavy duty in its build, but it still looks and feels high-tech and sexy smooth.
It's sexy looks is coupled with high-performance charging of mobile devices.
