V2L Electric Vehicle Discharge Adapter for MG

Works. Has some heft to it, doesn't seem cheap. Small enough to keep in the car all the time. Doesn't lock in place -- you can still yank it out of my MG4 after it makes the charger-locking sound (doesn't bother me I'm just pointing it out).

Works as expected and compact.

unfortunately it doesn't work no power going out
