Having issues with this adapter. It's been only registering 6amps max when my wife plugs in. I have to go outside and unplug everything, reconnect and plug in and pray. I don't know what she's doing wrong. Is the adapter supposed to unplug while still connected to the j1772 plug? Or do they need to seperate first? Before we get into it, the juicebox works fine on other evs that do not require the adapter
