The RUIZU Universal Travel Adapter and Voltage Converter appears to be a great travel companion. Most adapters are not voltage converters, but this one is. That means your 110v American electronics such as electric toothbrushes and shavers can be safely used with it. It also features 3 USB A ports and 1 USB C port on the bottom. I can’t verify the wattage coming out of the USB C port but it’s probably enough for lower power laptops.
Not every traveler needs a voltage converter capable electric adapter but some do. Those with electric shavers, toothbrushes and other devices may only have chargers at work at 110v. This device solves both the voltage conversion and the outlet conversion. You can also charge 4 other devices at the same time with the additional USB ports. The device offers many internal protections to ensure voltage does not exceed safe bounds.
