This is a clever piece of technology that is highly useful. So far it has charged up mp3 speakers , a little radio and huawai p20 pro phones as well as an apple iphone s7 phone and mini ipad. It also charged up a small 10,000 ma charger- highly reliable. All these items were charged whilst away on holiday (which has the same plugs as the UK). I also use this item in the UK as it easier carrying one charger around.
It is quicker charge on the top fast charge port for huawei p20 pro. The other ports will do regular charges to non fast items.
