Your power bank is more important than your Dankort. A statement you probably completely agree with, at least if you belong to the younger part of the population. Because then your life is very likely tied to your indispensable smartphone and your electronic devices with e.g. Facebook, Instagram and camera. With a Power Stone 5,200 mAh power bank, you get the equivalent of twice the extra charge and avoid the horror scenario that could otherwise occur if your device suddenly ran out of power! In other words, you can safely drive it home with the capacity here, but if you need less or more, you might want to look for the Power Stone 2,600 mAh and 10,400 mAh.
