Oh thank god, I'm talking to someone who knows what an amp is. Welcome fellow EE.

Yeah, alkaline batteries seem pretty innocuous. But C and D alkalines can produce over four amps. And the bottom line is watts, right ? Your wall wart produces just over 13 watts, if my calculator app is correct.

But six D alkaline batteries in series in your Vulcan is producing 40 watts of power. And that's why it just moans a little when you run it from your wall wart. Lack of power.

As seen above, this is my favorite way to power a Vulcan, or in this case a Stampede, same difference. I use two 4-pack AA holders with three IMRs and a dummy cell in each. Each pack produces 11 volts at approximately 5 amps. So that's 55 watts from each pack. Combined, this configuration generates about 110 watts of power. More than enough to keep your Vulcan firing all afternoon.

Alternatively, a 3S LiPo with a relatively low C rating would also do the trick. And there's plenty of space in the Vulcan battery tray to hold one.

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 😎
