Thanks for you sharing, guys. The way for me to fix charging when travelling is to take a charger. Most of time, this is for road trip. When I was planning to start a road trip, I will take a 400w power inverter. It is common DC 12v to AC 110v charger. I like to charge camera battery and shaver with it to connect with car cigarette lighter charger outlet. Friend recommends this charger to me in last year.
