An improved structure of a universal socket with polarity correction comprising: a cover, a wedging body disposed under the cover, and a shell disposed under the wedging body. The cover is formed with first neutral, first live wire, second neutral, and second live wire electrode socket holes. The wedging body is formed with first neutral electrode, first live wire electrode, second neutral electrode, and second live wire electrode holding holes. Neutral and live wire electrode plate accommodating grooves, and an electrode plate assembly are disposed in the shell. The electrode plate assembly comprises a first neutral electrode plate and a second neutral electrode plate electrically connected to each other and disposed in the neutral electrode plate accommodating groove, and further comprises a first live wire electrode plate and a second live wire electrode plate electrically connected to each other and disposed in the live wire electrode plate accommodating groove.

A compact battery and voltage supply controller apparatus for a tattoo machine is disclosed. The battery and controller are configured to connect the battery to the tattoo machine through replaceable internally received magnetic connection adapters. The toggle switch operated display screen provides easy-to-view status and health of the battery and incremental voltage adjustment using a voltage boost circuit and adjustment knob. The internal battery can be replaced and/or removed and recharged.

A power supply adapter includes a base plate, an electrical connector assembly disposed on the base plate, a support frame, a circuit board, and a shell body. The electrical connector assembly includes a hot connector assembly, a neutral connector assembly, and a ground connector assembly. When the adapter is plugged into a two-prong socket, the ground connector assembly is grounded to the two-prong socket. The support frame covers the electrical connector assembly and is affixed to the base plate. The circuit board is disposed on the support frame and electrically coupled to the electrical connector assembly. The shell body covers the support frame and circuit board and is affixed to the base plate. The power supply adapter can used with two-prong sockets that lack a ground slot, and provides grounding test function after being plugged into the two-prong socket, making it safe and convenient to use.
