UPDATED PRODUCT – 9 VDC 1000mA regulated switching power adapter – UL listed. Our 9V adapter is one of our most popular accesories, and we wanted to improve it by offering a higher amperage output and also have UL certification. So now you get 50% more current (a full Amp) and a higher quality, safer, adapter with FCC, UL and CE certification. All at the same price!
