    I'm really pleased with this purchase. The price was nice and it has worked very well for me. I use it mostly when I travel in order to make sure I don't have to stop to plug in, and it has not failed me.

    Best charger I have had. Itself charges very quickly as well as charges my phone. Item holds charge for a long time. I virtually never charge my phone via the cord anymore.

    I have a job that requires me to use my phone a lot and I am constantly having to plug it in to the wall or car to charge it throughout the work day, same when I come home. However, with this device I am able to quickly charge my phone or plug it in at the beginning of the day and keep it at 100% for 10-12 hours! I plugged the PhoneSuit into my phone this morning at 7:30 and used it off and on playing games, checking/posting to social media, used the internet, and listened to an episode of This American Life and the PhoneSuit keep my phone @ 100% battery power until 6:30. Some may find it heavy, clunky or hard to use once attached but I don't mind it one bit! It kind of even make my Iphone 5 easier to hold onto. For the first few days I used my phone as I normally would without it attached and used it to recharge my battery from under 20% back up to 100% and it did it quickly but drained the PhoneSuit. So, I have found it is better to keep it attached throughout the day and when it drains, just plug it in and use your phone with a full battery.
