Most modern electric cars are limited to 48 amp for AC charging. If your electric car can draw more, like earlier Model S and X models with two built-in power supplies, then perhaps buying an 80 amp connector would be prudent. It's also worth considering whether or not your charger will deliver more than the typical 40 to 50 amp output. And, indeed, TeslaTap 80 amp, 50 amp, 40 amp models can be found on sale. Just like the more popular TeslaTap mini 60 amp, 40 amp, 80 amp, the purchase can vary by a hundred dollars depending on the power selected.
