The car, not the EVSE, determines the charge rate.
At 120V, the car will draw up to 12A or 1440W.
At 240V, the car will draw up to 27.5A or 6600W.
If the EVSE can only deliver 240V @16A (3840W), like yours, you will only charge at 3840W.
Ok, so the most it can draw at 120v is 12 amps? Even though the evse is rated at 16 amps for 120v the max for the car is 12? It will be no faster at 120v than the ford evse? Im doing most of my charging at work which only has 120v available. Ive been using the ford evse and it usually leaves me about 10 miles shy of full when I leave work. I thought that if I got the proper adapter to use the dual voltage evse at 120v that it might charge a little faster since its rated at 16 amps. Or I can just show up to work an hour earlier. LOL.
Its a little more nuanced than that: The EVSE tells the car how much the EVSE can provide then its up to the car to determine how much power it will consume.
In my experimentation with my current adjustable JuiceBox the FFE usually consumed as much current as the EVSE said it could provide. Thus if you got an EVSE rated for a little bit more than the Ford one (16A @ 120V instead of 12A @ 120V) the FFE should consume that extra power provided--granted my JuiceBox is a Level 2 @ 240V; the FFE may have a set power consumption when charging from 120V.
