Can someone tell me about a portable power charger?

7. No, a "hot spot" is a place

where there is open wifi (but be careful using a public wifi connection and don't use any accounts requiring passwords).

Portable batteries can be picked up at Target, Walmart, computer stores, etc. They are large capacity (but fit in a pocket) batteries you can charge your phone up multiple times. You then have to recharge the battery by plugging it in to an outlet.
