Keeping a phone charged is an essential task for vehicle dwellers. It's more an issue of resource management (taking advantage of charging opportunities, carrying the chargers/cords) rather than spending money on special gear.

Charging a phone is a relatively simple task while living in a vehicle; it requires no expensive equipment. All other loads (like charging laptops) will be more complex.

The simplest approach is to charge the phone from cigarette port usb outlet while doing our normal driving. Some ports are powered with the ignition off but many will require the key to be on.

If you have access to normal wall power at home, work, etc, it may be easier to charge from a “wall wart” usb charger there, or charge a small usb power brick you can use to charge the phone later. This device, for example, acts as both a USB charger and a hand warmer for cold nights.
