Hi everybody. I'm looking for a charger to keep my iPad mini charged in the wild. I will be one month in the kyrgyz mountains where electricity is rare and I want to be sure my Ipad will stay charged even when using gps. I was thinking about solar charger (there is plenty of sun) but I'm not sure if it can provide enough energy. The second option is a 4xAA battery charger. Can you please give me some advice which device will wok better? Links to acctual product are appreciated. Thanks
