I just received my 450h+ this week and it looks like the Canadian market we only get EVSE that supports 110-120V EVSE and cannot use it with EV Doctor. In the US, what model did you get? I assume in countries that run off 220V-240V, you get the faster EVSE cable.

 

Typical outlets in the US are 120V, 15A, looks like the same model, at least with my California delivery model.

 

I read that this model adapter supports 240V as it's an international model. Just because in North America we have 15A 120V, the sticker is for our market.

This is what they a describe in the Amazon of the EVDoubler 120 product:
"The EVDOUBLER connects your L1 Charger to a 240V (or two 120V) outlet. This is possible because most chargers are a ‘240V INTERNATIONAL DESIGN ’. The US version IS THE SAME!! just a 120V label!"

 

This is what I have (standard Lexus NX charge cable) with 240V adapter and it works fine.
