Two AC power cords, different wattage. Potential problems?
I have an AC power cord to an elliptical, but the cord no longer works. From what I can tell, the wires on the inside have snapped. It's a class 2 transformer, Input: 120 V AC 60Hz 9W. Output: 9V DC 500mA.
Now, I found a cord that powers my elliptical on, but save for wattage, the class, input, and output are the same. The wattage on this one is 8W. I'm not sure if this will make a difference in using the machine, or if it'll be unsafe and damage something.
Can anyone who knows about these kinds of things give me a definitive answer? If you don't even have a clue, please don't bother posting.
Update:Both images show they're both positive polarity. Thank you so much!

You should be safe. The machine will only draw as much wattage as it needs. The ability of the transformer to handle a higher draw doesn't mean it pushes more electricity to your unit.
Voltage is the one to watch for, and that matches. As do all the other things. You're good to go!
ps, I'm assuming that the polarity is the same as well? My guess is that it is, or it probably wouldn't have powered up...but check for a little picture on the transformers that indicate positive or negative center pole. These MUST match, or you will wreck your toy!
8 watts has a little bit less current output than the 9 watts AC to DC converter. But it is OK to replace the broken one.
Wire can be repaired, mostly the opened wire is located either the far end near the transformer or another side where has the DC output plug.
