I live in Europe, and we have (usually) sensible consumer safety rules for everything.
So, here's my equivalent: https://www.action.com/de-de/p/2520398/pro-max-verlangerungs...
Germany's mains is 230 volts, so the 3680 watt limit implies 16 amps.
Other than hard-wired things like the oven and heat pump, I'm not sure my house has even one single item that draws 3.7 kW…
That's not equivalent because German household breakers are typically 13A, which is less than the 16A that extension cord is rated for. A 2.5A rated Europlug cord[0] is the closest equivalent, but safety standards help there too. Higher-current devices use Schuko, which will not readily plug in to Europlug.
I found an easy way to create an unsafe combination on German Amazon: a Europlug to IEC C8 cord into a C8 to C13 adapter. That's much harder to do by accident than the American version.
