Shayan, yes to the first part no to the last part.
This type of plug just lets you use a J1772 station instead of a wall outlet to power your onboard charger at the 1.3kWs like you'd get from home.
Now you could use this with one J1772 plug (male) for your onboard and a second J1772 plug (male) for you charge tank but the cord on here only
connects to the C14 side socket on the bike.
Sorry Pyromancy. If I ever no longer need it I'll repost it on the forum.
