Can a 5000 watt step up transformer be used to power your modified L1/L2 EVSE? I see a 5000 watt Seven Star Step up Transformer Voltage converter that says it can be operated continuous at 80% and will make a 120 volt outlet a 240 volt.
As mentioned by others, the maximum power available from a single 15A 120V outlet is limited to 1800W. Any higher current would trip the breaker.
Well, many residential outlets are served by 20A circuits these days, so you can get by with 2.4kw (resistive) if you were to push it, though it's not advised. The minimum you'd need would be probably around 25 amps, which you are unlikely to find anywhere in a residential setting. In fact, the only place you would ever be likely to see a 120V 30A outlet, is the old RV plug standard, though many places only offer a NEMA 14-50 and 5-15/5-20 these days.
Not to mention that a 3kw transformer (minimum needed) is going to be very bulky and extremely heavy!
The "Quick220" is a much better solution if all you have access to are standard residential 5-15 outlets, but again; try to find a dryer outlet first, that's your best/safest option!
