The present invention relates to a travel plug adapter, which will also be referred to herein as a travel adapter, for short. Using such an adapter it is possible to insert power plugs of a certain (domestic) standard into the outlets present at the travel destination. The present invention relates in particular to a travel plug adapter (10), which has a housing, a plug receptacle (16), and at least a first plug (38, 84) of a first standard and a second plug (28, 86) of a second standard, wherein each plug is assigned an actuation slider (22, 24), which is guided outwardly through a slide slot (42) of the housing and is designed to displace the plug between a standby position, in which the plug is disposed substantially inside the housing, and a usage position, in which the plug is usably disposed outside the housing, and wherein the first plug (38, 84) is assigned a first blocking element (106A), such that displacement of the first plug (38, 84) between the standby position and the usage position is blocked when the movement of the first blocking element (106A) is blocked, and wherein the second plug (28, 86) is assigned a second blocking element (106B), such that the displacement of the second plug (28, 86) between the standby position and the usage position is blocked when the movement of the second blocking element (106B) is blocked, characterised in that at least one blocking slide (100A) is also provided, which in a first position releases the path of the first blocking element (106A) and in a second position blocks the path of the first blocking element (106A), wherein the second blocking element (106B) acts on the position of the blocking slide (100A).

An air compressor (10) includes an air pump (34) with a pump inlet (34a) for receiving air to be pressurized and a pump outlet (34b). An air tank (14) includes a tank inlet (14a) coupled with the pump outlet (34b) for receiving pressurized air from the air pump (34), and a tank outlet (14b) for directing pressurized air from a tank outlet (14b) to at least one pneumatic device (24). A brushless DC motor (36) includes a rotatable output (36a) coupled with the air pump (34) for operating the air pump (34) to pressurize air. A control (42) is electrically coupled to the brushless DC motor (36). The control (42) changes the level of electric current drawn by the brushless DC motor (36) to thereby change the rate of rotation of the rotatable output (36a) and/or the pump performance level.

An electrically operated device (10) includes an electric motor (36) with an electrical cord set (30). The cord set (30) includes an electrical connecting plug (80) for coupling with an AC electrical outlet. The device (10) further includes a detector (46). A control (42) is electrically coupled to the motor (36) and electrically coupled to the detector (46) for controlling the level of electric current drawn by the electric motor (36) from the AC electrical outlet. The detector (46) detects whether the electrical connecting plug (80) is connected to a 15 Amp electric receptacle or to a 20 Amp electric receptacle and, in response, the control (42) establishes the electric profile of the electric motor (36) to correspond to the 15 Amp electric receptacle or to the 20 Amp electric receptacle.
