This heater does not come with a power supply. It runs on a standard 5V. But do not plug it into your computer its does not have enough power to heat up the lube. Use a 2 or 3 Amp wall charger used for tablets and ipads
The heater is weight activated and was made to heat up a mug/cup of water so if you plan to use it for your lube, you will need something to weigh it down
