| I want to get an AC adapter for my Mark2 but the Canon one is $180 and after market ones are $30. I'm all for saving money but that price drop scares me, I don't want to be frying the electronics with some cheap knock off. Anyone have any experience with these? |

These things are CHEAP to make, at $30 they should be able to use high quality parts and still make a 500% profit.
I suppose the only way to KNOW is to buy both and do a few tests with a voltage tester, but I can't really see how $180 would ever be a reasonable sum for such a device. |

I would agree with Cory. A $5 charger I might have some concerns with about quality. Just do a little research and make sure you get once made by a company with a good rep.

I have the Canon versions at work where they are used with a 5D and 6D mounted to microscopes. Looking at those adapters, I simply cannot understand the pricing. It's a wall-wart power supply with a faux battery on the output end to mate with the camera.
Were I buying an AC supply for my own use, I would research the aftermarket manufacturers and buy one of those. Do keep in mind, though, there is more to one of these supplies than simply supplying the correct DC output voltage. A multimeter may read precisely the correct DC voltage, but that's not the whole story. Cheap DC supplies tend to have a lot of "ripple," that is, an AC signal that leaks through. Setting a multimeter on AC and testing the supply voltage should ideally result in a 0.0V reading. There will typically be some ripple, but it should be minimal. Excessive ripple can cause problems or damage the attached electronics. The other consideration is surge suppression. I don't know how well protected the Canon supply is, but I would bet that the inexpensive supplies are not well protected.

| thanks for the thoughts guys. I found an aftermarket on Amazon that was only $12 but had 36 fairly positive reviews. I'm not planning on using this long term. I'm having a BBQ for my son's graduation and I am setting up a photo booth so obviously the camera needs to stay on. After that I'm not sure what use I would have for it. |

| if you want to be extra safe, run it off a UPS. |
