Is that a Juice Booster 2 EVSE (not visible in the photo) allowing you to charge from that random looking GPO (15 A?) on a tin box you happened to find in the outback?
They seem pretty handy, though at nearly 10% of what I paid for my second hand EV, it's hard to justify at present. It makes more sense with EVs like the Kona that have a reasonably powerful on-board charger.
