I made an adapter to use J1772 level 2 when I had an older conversion car. The charger used an input of 120v. I found that most ‘commercial’ locations have 220 volts at the plug, so I had to get a transformer that would put out 120v when supplied with 220v.
When plugged in to the rare Level 2 charging station with 240v (such as at a house) the transformer output would be about 160v, much higher than the charger could use. I say this because if your charger expects 240v, and it is transformer-based, you may not be getting full charging voltage from the typical Level2 charging station. If it is OK with a wider range of voltage -around- 240v, than an adapter will probably work out.
