There's no reason when you've got a portable generator (e.g. an alternator) with a power outlet (e.g. a fag lighter socket) typically right next to you, that you should ever run out of battery - as long as your charger is up to the job.
Get a decent charger and even with the GPS and every service under the sun running, you'll still easily finish the trip with 100% charge, even if it starts from empty.
