How do they keep their GPS and Spot batteries charged?

Curious how the Divide racers keep their electronics charged? Do they have solar chargers? or do they plug them in at electric outlets at stops along the way?

Most long-distance riders and racers choose gadgets that use regular old disposable batteries. My Spot takes AAA lithium batteries. The same for my headlamp and GPS (AA for the latter), although they can also use alkalines. On shorter rides, I use rechargeable batteries.
