Oh wait, would something like this work?

Yes something like that one, but not that one. That one doesn't have the required 12v@2.5A output, it's undersized.

Yeah I found that exact replacement this morning. I was searching/posting from my phone before and wasn't having luck. When you sit down at an actual computer things seem to work more smoothly
12v fairly high amp are pretty common since that is what all the RC people use for their battery charger input.

From the Amazon listing -
"Compatibility:This PSU will adjust the output current (2.5 A Max) accordingly to different devices, so it is a prefect replacement for all 12 Volt 0 - 2.5Amp power supply adapters"
I'm unsure what that actually means (perhaps just a bad translation?), but since it is Prime, I would return it for one from a different manufacturer, perhaps a "brick" type, rather than a "wall wart".
If that doesn't fix it, the massager itself may be bad (worn out) and drawing more amperage than it should when "loaded".

Yeah I plan on returning it for sure. I don't think the massager is worn out. It get's used but not that much and WAS working before the PSU was damaged.
I'll try another one, but having issues finding a brick one. Think I could just go 3A wall wart?
Times like these I REALLY appreciate having a DC clamp ammeter, but maybe if you have one of those killawatt AC power measuring things to see if the device is drawing more power than expected.
Stuff like this I always suspect bad or weak connections.
Its rare, but I had one experience with a printer that was DESIGNED to have the power supply limit current on paper jams.

So, logically the power supply must be sized to provide at least as power as the connected device will draw from it. You'll see on your original power supply that the output rating is 2.5 amps at 12 volts DC. For a replacement, you want to find one that can deliver at least 2.5 amps at 12 volts DC. 3 amps is fine; 5 amps is fine; 10 amps is fine... The amp rating is the most that the power supply can provide without exceeding its design limits. It does NOT mean that it will shove that amount of current into your device. The nature of your connecting device determines how much current it will try to draw from the power supply (which based on the original power supply should be less than 2.5 amps).
Sadly, it seems that power supplies may be as hit or miss on Amazon as KN95 face masks. That one you picked has some pretty bad reviews, but I didn't see any that really inspired my confidence. I hope your next pick is good one.

Thanks. That sorta makes sense... I know virtually nothing about "electricity".
Something like this a better bet?

I really wish I could help you identify a good one, but the picking a winner on Amazon seems like playing Russian roulette.
FWIW, I would shy away from "universal" power supplies with switches to change the output voltage to whatever is needed. Just one more point of possible failure, and lower voltage options (<12 volts) suggest to me that the device is aimed more at lower power devices and perhaps the top end watt rating is more aspirational than actual.
Okay, if you twisted my arm I might take a chance on this one:
SHNITPWR 12V 5A 60W Power Supply
But really -- your guess is as good as mine.
