WHY DO YOU NEED A POWERBANK?

We highly recommend getting a powerbank - essentially, an external battery in a sealed case. Powerbanks come with a USB cable; you connect it to a power source such as a laptop to charge the powerbank. After your powerbank is fully charged, you carry the charged up powerbank - and the cable - in your pocket, purse, backpack, briefcase or whatever and use it to charge the phone (using the same USB cable) when you see the battery meter sinking into the sunset.
