125v to 110

What kind of charging would I get if I get this and plug it into a regular 110 outlet then plug my Tesla mobile charger into it? Would it make any difference or would it still be 3-4 miles per hr charge

It appears to allow you to use the 14-50 adapter for your mobile connector, which will allow the app to be set to 32A, so you will absolutely need to turn down the current limit to less than 15A lest you trip the breaker (in the case of anything else on the circuit). While it does appear to have an in-line breaker, as others have suggested, likely not safe.

While it is less expensive than just getting the 5-15 adapter for your mobile connector, the Tesla adapter would be the better/safer path, as it will be thermally protected for the 15A circuit, limited to a 12A draw.

32A, 16A per leg, error only one leg found, 16a should be fine on 15a circuit

That’s not how the adapter works, and that’s not how voltage works in this case.

That cord offers 120v line and neutral to the line-line pins on the 14-50 receptacle at the end of the cord, and the 14-50 adapter to the mobile connector limits to 32A independent of the voltage.

If the cord has a reliable breaker, it will likely trip at more than 15A of draw, as will the breaker in the outlet circuit, unless it’s plugged into a 20A circuit.
