I have always burned through my iPhone battery quickly. I use my phone for about 16 hours a day and end up recharging it at least once, but usually twice each day. I was leaving town and knew I would be in meetings each day and not have the opportunity to recharge my phone, so I felt it was time to purchase a battery pack. The iTorch was reasonably priced and had good reviews, so I decided to purchase it. The instructions were easy to understand, and the pack wasn't too bulky to carry. When my phone died, I connected the pack then put it in my pants pocket. I used my iPhone cable which allowed me some extra length. The phone comes with a cable to charge the pack but not one to connect it to the phone. This would have been a nice addition, but I had several already, so it didn't concern me. The charge time was quick, and it allowed me to use the phone while it was charging. While I never thought I would have a need for the flashlight or laser, I actually ended up needing one for my presentation during the trip.
