My family is constantly on the go and we don’t always have access to a power source. I have really enjoyed using the ZAGGsparq portable charger. You charge it up by plugging in to an A/C outlet and then you carry it with you. Any device that can be charged with a USB cable will work as long as you have the cable. My kids love to use it while we are out and about and I like knowing that I will never have a dead battery in my phone!
Learn about the ZAGGsparq on their website. I purchased mine at an AT&T store.
