According to the Amazon reviews, this device has caught fire more than once. And when it works, the fan is quite noisy.
What I do is plug a US extension cord into the wall with a single mechanical plug adapter, then plug all my chargers into that extension cord. They accept 220 volts at 50 Hz. A single Anker multi-port charger takes care of my need for high-speed charging of Android and iPhone devices, as well as my Pixel phone using USB-PD with a USB-C cable.
