Very simple travel plug which is but practical. He's not 100% sure by its simple appearance, since you can get to the metal contacts, if it is not fully inserted in the socket. For German plugs but very convenient as well plug with 3 contacts can be inserted easily. ATTENTION: This is actually not allowed and is a security risk. But: It saves the carrying around a much larger adapter. Please note: Most lead this plug 115V, so check in advance whether the instrument is designed for 115V. The voltage from the power outlet in Germany is 230V.
