Bending NEMA 5-15 wall plug for electric car charging

The place I want to charge has a 5-15/20 passthrough outlet

 

If I twisted the nema 5-15 hot plug so that it could fit in the 5-20 passthrough, could I charge my car at higher than 12 amps?

I could purchase the correct adapter but it costs 40$ and I don't want to pay for another adapter lol

 

How unsafe is this

 

Also are there any adapters that are cheaper that accomplish the same thing

Just don't. Is $40 worth the risk of burning down your place and having insurance not cover it when they find your hack job in the debris?

No it's not, but i guess the other part of the question was what makes the two plugs different physically, besides the sideways part?

Really, the different plugs are to keep smaller cables away from high-current loads, i.e. can't accidentally use a 15A-rated cable with a 20A load because the plug won't fit in the 20A socket, or you can't accidentally plug a 20A device into a 15A-rated outlet.

That makes sense

The individual wires inside the cable could be thicker, the insulation on the individual wires could be thicker. Even the contacts inside the plugs where the wires are screwed to the contacts could be different, made with more metal or spaced a  bit more. 

 

Wires have resistance, so they'll warm up as current flows through them. If there's too much current and wires are too thin, the wires will get very hot and potentially the temperature could get above the melting point of the insulation on the wires inside the cable (usually 85 C or more) and once the insulation of individual wires is melted, they may touch and cause short circuits. 

 

Spend the money on the proper adapter, you'll use it for a long time.  Just imagine spreading those 40 euro across 5-10 years ... you're probably spending an euro each week or each day on coffee or other crap.
