Just get a 10000mA battery bank, it should last long enough to charge most of your devices, I used one + my light battery also acted as a bank should I wish to use it.
I doing think a solar charger is of much use. Definitely take a power bank (for backup and load shedding), in general there are adequate charging facilities at the SS's. Racers may use a dynamo hub, but that doesn't make sense if you're doing more than 14 days.
