Provided is an electrical device. In a setting unit, a right-room temperature display unit displays a set temperature or the current temperature of a first housing room. A left-room temperature display unit displays a set temperature or the current temperature of a second housing room. A right-room temperature setting button is an operation unit for a user to switch the set temperature of the first housing room. A left-room temperature setting button is an operation unit for a user switch the set temperature of the second housing room. The set temperature difference between the first and second housing rooms is controlled to be within a prescribed value. When the set temperature of one of the first and second housing rooms is changed so that the set temperature exceeds a prescribed value, a microcomputer automatically changes the other set temperature so that the set temperature difference is within a prescribed value.

A power tool includes a housing including: a body part having a substantially cylindrical shape and extends in a front-rear direction; and a handle part connected to the body part. The body part includes: a driving source; a power transmission mechanism part configured to transmit a driving force of the driving source; and a tip tool holding part to which the driving force of the driving source is transmitted from the power transmission mechanism part. The handle part includes a switch. A top part protruding from a surface of the handle part is formed on a side surface of the handle part along a longitudinal direction of the handle part. At least a portion of the top part is arranged at a position deviating rearwards from a center of the handle part in the front-rear direction.
