I just put my phone in the charger at night and charge them both at the same time so in the morning I've got a fully charged phone that I remove from the SaFPWR and take both along with me. Whenever the normal battery for the phone dies down I put it into the SaFPWR and it charges up my phone and runs off the battery in the SaFPWR. When the SaFPWR dies down I've still got a fully charged phone ready to go. Depending on how much you use the internet this product will buy you an extra 1-2 days of charge without ever needing a wall outlet (if you use it in the manner I've described).
So I ask would you be interested in a product like this? How much would you be willing to pay? The external batteries that don't last as long and don't recharge your phone run $80 at Best Buy and just a plain leather carrying case will go for 30-50.
