I purchased the superbattery about six months ago and was amazed at how many times I actually used it. I live in an area of Texas where the power is constantly being knock out by storms. At times, the power can be out for a day or two. The superbattery allowed me to keep my phone charged, and see in the dark using the light. If you live in a storm prone area such as myself, this is a great product to own.
Handy during storms!
