"Imagine that you are about to go on a vacation or a business trip, and that instead of carrying number of different chargers for your laptop, camera and PDA, you can bring only one device. If you like this vision, than Prestigio Power Bank 501 is the right choice for you. In simple, this is external battery which can be used for supplying all kinds of power consumers. This is a good quality device that seems firm with dominant black color and a couple of silver details. Bigger part of front surface has nice piano finish with dominant Prestigio logo."
