I never tried one of these portable batteries before, so this was a pleasant first for me. I received the iTorch right before leaving on a business trip, so the timing was perfect to get to test it on the road. While this product was packaged nicely, I will say the picture instructions/illustrations were a little confusing in that they showed an AC adapter in the picture instructions but there was a small note saying an AC adapter was not included. No matter for me, since it still came with the USB cord which I was able to plug into my own USB wall adapter. The other thing the instructions didn't indicate was how long I should charge the battery for the first time and for each time thereafter. However they did indicate what the 4 blue lights would show to indicate battery life. I plugged it in and noticed the 4 blue lights blinking in sequence, and over time they would each incrementally light up solid until all 4 were lit solid, indicating that it was fully charged. The first charge took about 3 hours to get to all 4 lights lit solid. I thought it was a nice feature to have both an LED flashlight and laser pointer built in to this device, though I didn't think I'd be getting much use out of them - however the flashlight could serve well in a pinch such as a power outage when you don't want to burn the battery of your cell phone by using its flash. While on my trip, I put this battery to the test: with one charge, it fully charged by iPhone 5, my iPad 2, my iPod, and charged my Blackberry Bold twice. Once it finally died, it only took a little over 2 hours to recharge fully again. I happened to be traveling with my boss, and while we were at the airport for our departing flight his Blackberry battery died - instead of hunting around for an unoccupied outlet I pulled out my iTorch and let him charge his Blackberry on it with his USB cord. He was pretty impressed and said he's going to order one for himself. Score.
