Use your smartphone while on the go and charge it at the same time with a phone mount and car charger. You can connect a car charger to the cigarette lighter in your car. Most chargers have 2 USB connectors, which is useful if you want to charge your iPad and smartphone at the same time. Make sure the car charge comes with the right cable for your phone. You can put a phone mount for the car on your dashboard, windshield, or in the air vent. That way, you're always prepared to hit the road.
