Solved! Tesla (NACS) and J1772 Charging for Stark Varg

First time posting here. I’ve been searching for a while and couldn’t find a clear, working solution for charging my Varg MX from Tesla or public Level 2 chargers, so I figured I’d share what I got working. Please note: This DOES NOT work with Tesla SuperChargers. Don't even try it! Wall Connector and Destination Chargers only!!!

Goal:
Be able to charge the Varg from:

• Tesla Wall Connector / Destination chargers (NACS)
• Standard J1772 Level 2 stations

Portable Setup:
I removed the stock charger from the stand and mounted it in a weatherproof portable storage box so I can carry it on the bike and charge while out riding. Still looking for a good mounting option for the box.

Solution (what I used):

• NACS (Tesla) → J1772 adapter (A2Z Stellar)
• J1772 → NEMA 6-50 EVSE adapter (must emulate a vehicle)
• Stark Varg charger (mounted in portable case)

Setup chain:
Tesla Charger → A2Z (NACS→J1772) → J1772→6-50 adapter → Varg charger

Results:

• Charging starts immediately (no fiddling)
• Stable at ~3.3–3.5 kW
• No dropouts or overheating
• Works on both J1772 stations and Tesla Wall Connector

I’ve already tested:

• Public Level 2 station (Charge Point) → worked perfectly
• Tesla Wall Connector → worked instantly
• Added ~10% charge in ~20 minutes

Bonus:
Same setup works for my 72V mini truck charger as well.

Notes:

• Your J1772 → 6-50 adapter needs to properly emulate an EV (cheap passive ones won’t work)
• Charging speed is limited by the Varg charger (~3.3 kW), not the station

Conclusion:
This effectively turns Tesla and J1772 infrastructure into a usable Level 2 charging network for the Varg, and makes mobile charging on rides totally doable.

Happy to answer questions if anyone is trying to do something similar.
