Devices draw only the current they need. However, because this is an unregulated supply, a lightly loaded device will run slightly above 6V, so verify your device's voltage tolerance.\u003c\/p\u003e\n\n    \u003cp\u003e\u003cstrong\u003eQ: Will this work on 220–240V power outside North America?\u003c\/strong\u003e\u003cbr\u003e\n    A: No. The PV-61P is built for standard 120VAC 60Hz domestic wall power only.\u003c\/p\u003e\n\n    \u003cp\u003e\u003cstrong\u003eQ: What happens if I use the wrong polarity?\u003c\/strong\u003e\u003cbr\u003e\n    A: Reversed polarity can damage connected equipment.
