I need an external power bank to provide a lot of juice for my hungry device-ipad mini in my December trip. I have looked around and targeted one on ***URL REMOVED***, i prefer the style and nice look, but it probably can not offer me sufficient capacity to charger my device. The cuss is, less than one time!!I diverted my attention to amazon and ebay and now struggling with which power bank? who can tell me that whether a 12v 36000mah power bank can charger my device? OR just need care more about the output capacity?
