I received the iTorch IMP52D about a week ago and have played with it for a few days. The product is easy to use and doesn't take a rocket scientist to operate it. The simple instructions that came in the box show exactly how to use it for those who are new to the tech world. I was able to sustain my battery on my tablet while traveling with my son last weekend. No need for extra charging ports in my car which was already occupied by my phone charger.
