It didn't come with one, but I found that a common US 12V DC power supply intended for a CCTV security camera is inexpensive and more than adequate. The manual suggests obtaining the Cat. No. 273-1652A adaptor, but they're quadruple the price. The unit will charge 5 NiCad AA cells with the proper dip switch setting inside the battery compartment.
