The USA to Schuko 2-Prong Adapter from Watson adapts 2-prong USA Type-A plugs to Schuko type-F two-prong ungrounded devices, so you can use electronic devices with self-switching power supplies into Schuko type power outlets.
Schuko plugs are slightly thicker (4.8mm) than the Type-C Europlug (4.0mm). Schuko power outlets can be found in Germany, Albania, Austria, Belarus, Bosnia and Herzegovina, Bulgaria, Chile, Croatia, Denmark, Estonia, Finland, Greece, Hungary, Iceland, Indonesia, Iran, Italy, Kazakhstan, Latvia, Lithuania, Luxembourg, Republic of Macedonia, Republic of Moldova, the Netherlands, Norway, Pakistan, Portugal, Romania, Russia, Serbia, Slovenia, South Korea, Spain, Sweden, Turkey, Ukraine, and Uruguay.
Please note that this adapter adapts only plug type, and not voltage. It should be used with power converters or devices with universal power supplies.
