Powerbanks in the test - juice on the go

When your mobile phone runs out of power on the road, they promise to save you. But the powerbank test shows: They don't always deliver as much energy as they say they do. We tested 19 power banks between 10 and 100 euros. The practical test confirms this: All of them can charge smartphones and tablets as well as laptops - as long as they support USB-C charging. However, we found significant differences in the amount of energy that can be used and the charging speed.
