    I used this during NASCAR weekend in Phoenix. When my phone was low I used it to recharge a few times. It kept me going during a 13 hour rain delay when I needed my phone most.

    Does everything it says it does on the box. Very big battery backup for the price it'll charge two iPhones at the same time and still have enough juice to put a good charge on an iPad. The digital display is nice gives all the info you need monitor.

    Needed this on vacation. Was so convenient! We used it several times before we had to recharge it. It is very sturdy. It survived my dog's curiosity before I could get to it!

    It's a little slow to charge, but if I know I need it the next day I just put it to charge at night and it's ready when I wake up. The next day I can charge my phone from 0 to 100% four times when it's fully charged. It also charges my phone (iPhone) and my husbands (galaxy) pretty fast.

    Great compact power supply that my son got to go camping with. It can power a cell a couple of times as well as charging a led light. It's pretty quick.

    I have had this powerpack for about 2 days now and it has been a bit of a hassle to carry around. Now this being my first time ever having and using a powerbank may be the reason why this isn't quite as portable as I initially thought it would be. Its quite bulky actually and doesn't quite fit your pocket very easily. Compared to others on the market its quite thick and hard to find a place to put it when in use. The display is a nice feature but also unnecessary since i feel it takes energy away that could be used to actually charge the phone. Which brings me to my next point that it only charged my phone from 0-100% about 4 times and was dead before the 5th. Im not sure if thats average but I thought it would be more. A few more at least and i believe that without the display on the whole time charging that it would. Overall it does what you want it and doesnt heat up even when using the special Samsung chargers of the previous generations. So 3.5 out of 5 since the pricing is actually a great deal.
