I have used my ban.do charger for about a month now and every time I have used it, I have been very pleased with the charging ability! My phone has been dead and it has charged it back to 100%. It's a great charger to have as a backup! The only thing I don't like about it is when it's connected to my phone, it's rather bulky. I wish the charger was shorter in length, but considering it does an excellent job of charging my phone, it is something I can overlook! On a side note, the charger only holds enough to charge my phone one time.
