A conformal power adapter for insertion into a lighted artificial tree and for converting power received from an external power source to a power usable by the lighted artificial tree. The power adapter includes an elongated housing including a first end, and a second end; a printed circuit board assembly including power-converting circuitry for converting an input electrical power to an output electrical power for use by a lighted artificial tree having a hollow trunk section, the printed circuit board assembly located substantially within the elongated housing; a power cord secured to the first end of the housing and in electrical connection with the power converting electronics, the power cord adapted to transmit power from an external power source to the power-converting circuitry. The elongated housing enclosing the printed circuit board assembly is sized to fit substantially within the hollow trunk portion of the lighted artificial tree.
