Would this set up be ok to charge?

yes

 

"Most soda vending machines run on 115 volts at about 10.5 amps. Most commercial grade three prong outlets will be acceptable to power a vending machine." Frequently Asked Questions | Vending Solutions

Since it is most likely a 15 Amp Breaker, this will not leave you enough power to charge with. Too bad too, that was a nice looking Receptacle.

 

There are 20A 120VAC circuits but those have a small, horizontal slot on one leg.

I would first negotiate with the landlord to coordinate testing.

I think the 10 gauge cord is over kill. I bought a 2 pack of US made 50' x 12 gauge cords at Costco for $50 bucks (of course they are probably gone from Costco now). I have been charging my Prime with the charging cord plugged into the extension cord for over 9 months with zero issues.

About the Coke machine, just try it and see what happens. Worse case is you car is charging and a cooling cycle comes on for the cokes and the GFI breaks or the breaker breaks. Then you know. My bet is it goes along just fine.

 

Have you talked to your landlord about using the outlet? I would find out what size circuit breaker that circuit breaker is on.
It could be on a 20 Amp breaker or a 15 Amp breaker but like someone mentioned the receptacle is a 15 amp.
Or like others have said just try it. The worst case scenario is you trip the breaker when the coke machine turns on or the receptacle overheats.

This is a 20 Amp Ground Fault Receptacle

And they said it is OK ??
Better get that in writing !!!!

You need to select the lowest charging rate AND you need to find out where the breaker box IS that serves that outlet. It is NOT the red button; that is the GFI. Chances are good that you don't have access to the actual circuit breaker.

 

Yes a little confusing. The outside outlet is a GFI (Ground Fault Interrupter). This is for safety in wet environments (bathrooms, outdoors etc...) This can be a failure point and can be tripped by the motor in the coke machine or other events. You would reset it outside if this trips. The breaker, located in the teh breaker box can be tripped by overload or other conditions. If it fails it could be either - you will just have to check.
