The IMP52D (iTorch) is a very sleek cool looking back-up power source for my iPhone. It is about the size of a swooshed Twinkie, perfect to grab and go. I needed to purchase a short USB lightning cable to use it, but it was inexpensive and makes this a great backup power source. I loan it to others in need almost as often as I use it. It is a great design with a great feel. I have a cigarette lighter charger from an old phone that I sometimes use to recharge my iTorch when I am in my car. It charges fast and can boost my phone to 100% even when it is dead, and it still has some juice to spare. I rarely use the flashlight or laser pointer, but they are cool little features that could come in handy. Great price well made, very cool external charger. The only thing that could make it cooler would be some kind of retractable lightning cable for charging an iPhone or Droid. The AmazonBasics 4" cable is the perfect complement, but I wish Trent devices came with short cables for charging.
