Atlas mount AC/DC converter question

It says the Orion 2 Amp AC-to-12V DC Power Adapter is rated at 12v 2amps. Any reason this wouldn't work? Only $10 bucks and I can have it in two days.

It needs to have a Positive(+) tip/center pin. If they don't state anything, they are normally that way.

Orion 5 amp converter
The converter, of course, only provides the current demanded.

A DC battery is certainly a flat voltage source but the tiny amount of ripple and noise on good power supplies poses no risk to any electronic gear. Batteries vary the voltage as the battery is depleted. If you deplete a battery down too far (usually down below 11-10.5v) you'll start to get strange problems with many mounts. You need to correctly size a battery to match your power needs (mount, dew strips, cameras, etc.) and you need to treat the battery with care (don't deplete it too far, recharge after every use or two, etc.).
Both technologies have their good and bad points, and anyone making the choice should be aware of those differences.
I agree there are times when a battery is a good and convenient choice but no one should be afraid of using a good AC 12v power supply with their scope/mount.
