I thought this would be a good spot to help me with a question:
I will be traveling and plan to use my cell phone often for a few days away from the grid. I am looking for an external, portable charger or extra battery that can give me the most cell phone use time but still be somewhat compact.

I will be trekking through the Himalayas soon and want to use my gps up there. Also, I am not impressed with the solar chargers as I have seen them. They seem to take very long to charge.

Thanks
