An amp and a half sounds like a lot when you're used to playing around with digital electronics and stuff... but high-torque motorized devices are in a whole different tier.

(I thought maybe the screw I used to hold the center tip against the positive battery-box terminal was too high of a resistance because it was black, so I checked with an ohmmeter and it seemed like a solid connection.  Yeah, definitely just lacking power.)

So 40Watts is my goal... and I can probably get away with 10V x 4A, give or take...

This whole rig cost less than $20, and it's rechargeable hundreds of times. IMHO it's not worth screwing around with wall warts and power supplies. Just go epic 😎 That is pretty epic, and not nearly as expensive as I would've expected.

But you still gotta charge the durned things, and $20 > $2.99. So I'm not quite dissuaded from pursuing the "AC-powered Vulcan" idea if I run across a cheap power brick. I mean, the silly Vulcan comes with a tripod, so why not be burdened by an extension cord plugged into the wall? =D
