Excellent quality power supply. Disappointed that it’s made in china, but what ISN’T these days? I am extremely happy about this being a variable voltage power supply because I am forced to use the non-standard wall unit for my blood 🩸 pressure tester. I am able to set this power supply to the required 6VDC to make my blood pressure machine operate correctly 😆, it works perfectly, of course 😂. 73 de Araha Beach 🏖️: Okinawa
