New Trent iTorch IMP52D is just simply amazing. I have been charging my Iphone 5 for 3 weeks with this device and it still has power!! Not only does it charge your phone but it has a laser pointer that I use in my class room. The laser is very bright and can reach long distances( I used it in the cafeteria --with lights on and from back of the room and WOW it reached and still was very bright. Oh it also has an led light --Can't ask for anything more. My colleagues were so impressed they going to order the iTorch.  It is well worth the money and the peace of mind it gives you because you will never have a dead cell phone again!!
