We are currently traveling in United Kingdom and this is the perfect adapter. With the multiple USB a and USB-C ports, we have charged as many as four things at the same time. Phones, hearing aids, iPads. And one of the USB-C ports is a fast charger and it works great. This replaces a 10 year old adapter and Is exactly what we needed. Of note, it does not convert voltage so you canāt plug in a hairdryer
