This invention provides an adapter device for powering a portable inhalation device, characterized by comprising: a power-side connector configured to connect to a power source; a device-side connector configured to connect to the portable inhalation device; and a power adapter configured to adjust electrical energy received from the power source so that the electrical energy can be used by the portable inhalation device, wherein the portable inhalation device uses the adjusted electrical energy from the power adapter, rather than chemical battery energy, to vaporize an inhaled substance. This adapter device enables the portable inhalation device to eliminate the need for a battery, thereby reducing device weight, simplifying device structure, reducing manufacturing costs, and eliminating environmental problems associated with battery disposal.
