I bought ($35) the 5-20 adapter for the Tesla UMC. That allows you to charge faster (16A) on a 20A circuit. Many outlets in garages and commercial buildings are 20A. My testing at home showed ~50% increase in charging rate going from the included 5-15 (15A) to the 5-20 (20A) on my 20A outlet in my garage.
I figured it was worth the $35 to have it in my truck on trips where I might charge at 120v.
Interestingly, the Tesla chart on their adapters page just shows 4 mrph for the 5-20 vs 3 mrph for the 5-15, a much smaller gain.
