I am currently using a little Hornady digital scale after going through a Midway and a Lyman, both of which malfunctioned and had to be returned.

My gripe is that the battery doesn't last very long, and those little 9v batteries are pretty expensive.

There is a port for, I believe a 12v adaptor.
Can I just go out and by an AC12v adaptor or should it come from Hornady?

If it runs off a 9-volt battery, then it's likely the power supply should be 9-volt. It should state this somewhere on the outside, and probably near the port. But, a converter from Radio Shack will work as well as any other. Just be sure to get the correct voltage and enough amperage (too much amperage is not a problem).

I know you are right about there being a discrepancy with the voltage...
I don't have it in front of me, but from memory on the booklet it said a 12v adapter is required.

Thanks for the info.

I will have to disagree with bugs comments.
If it is a 9v the adapter may very well be a 12volt as the scale may have dual source adaptation. Secondly, though most adapters of this nature have a i-out measured in mA, it is possible to buy an adapter that of 12 volts that has 3 amps to it. This would not be a good thing for the led and related solid state devices it may have.

I thought the MA rating had to match as well?

I've found using a switched tap at the receptacle handy; it shuts the transformer down between uses.

The ma. available needs be equal to or greater than required by the scale. Voltage and polarity must match, or POOF goes the components.

I use the RCBS electronic powder dispenser and scales (made by PACT, I believe). The AC adaptors are different, and the appliances come with a warning to use the proper adaptor or damage could occur.

These 12V adaptors are only rectified, not stabilised, so if there is stabilisator inside scales, it could need higher voltage to work properly . . .
