Used this as a replacement for an air compressor, 12V 15A circuit. I clearly should have read the reviews and/or done the math before purchase, because as I can report after taking the fried fuse out of the tip, it turns out this Roadpro replacement plug is rated at 2A.
Remember your basic physics! V [voltage] = I [current] x R [resistance], and P [power] = V x I. With the provided fuse, the plug can supply approximately 2A * 12V = 24 watts. My compressor needs something like 15A x 12v = 180W. Needless to say, the fuse in the Roadpro plug burned out in half a second.
If you're looking for a high-draw plug, look elsewhere. The spring clip leads actually make it significantly harder to splice, solder, and tape / shrink-tube.
Guess I'm going out to replace the fuses! FYI, this plug takes 6x30mm fuses.
