If you use your phone, get an external battery. Even the smallest one would probably suffice. There are some that are the size of a butane cigarette lighter.
Yesterday, I used a 12000 mAh battery (emergency starting battery) left uncharged for a year, to start my 5 liter Mustang which was sitting for 2 months. This little gizmo is the size of a reading glasses case and comes with its own jump cables, amazing!
I am considering taking one with us on a 10-day tour this summer (it has a USB outlet and a laptop charger), using a Smartphone and RWGPS.
