This thing is a lifesaver for me! I'm in Sales and work out of my car and in other's homes and I can now charge my phone in my pocket or from my bag and I don't have to have an extension cord or sit close to a plug. Also great in airports /planes when your battery dies quickly while the phone is always searching for a signal. A MUST HAVE!!!

I was able to fully charge it once. Now it won't hold a charge and is only able to charge my phone for about 10 minutes.

Don't lose the charger cord because it takes forever to charge with others. For what I wanted it for it does a really good job.
