WOODLAND HILLS, CA – A brand-new Tesla accessory is turning heads across the overlanding and EV communities tonight: a factory-approved 240-volt AC power outlet adapter that plugs directly into the Model Y’s charge port and delivers up to 9.6 kW of continuous external power.
The groundbreaking capability was first demonstrated in a viral X video posted today by Tesla owner and YouTuber Nic Cruz Patane (@niccruzpatane), showing the adapter powering an entire off-grid campsite including:
- A full-size electric skillet cooking dinner
- A 1,200 W electric kettle
- Multiple LED light panels
- Laptop and camera battery chargers
- A portable air compressor
All running simultaneously from the vehicle’s traction battery with zero gasoline or external generator required.
Official Name & Specs: Tesla “Mobile PowerWall” Adapter (Part # 189-510-00-A)
- Output: 240 V split-phase AC (L1 + L2 + Ground), NEMA 14-50 receptacle
- Max continuous power: 9.6 kW (40 A @ 240 V)
- Peak power: ~11 kW for short bursts
- Compatibility: 2024–2026 Model Y (all variants) with Hardware 4 and the new bidirectional charger
- Also confirmed working on refreshed Model 3 “Highland” and 2025+ Cybertruck with latest firmware
- Price: $450 (currently waitlisted on Tesla Shop – delivery estimated Jan–Feb 2026)
- Safety: UL-listed, automatic thermal throttling, GFCI built-in, charge-port door remains fully sealed while in use
Why This Changes Everything for Overlanders & Emergency Prep
Until now, Tesla owners wanting AC power on the go were limited to the built-in 120 V bedside outlets (1.7 kW max in the Model Y) or aftermarket DC-DC inverters that wasted 15–20 % of energy in conversion.
This new adapter uses Tesla’s integrated bidirectional charger (the same hardware that will eventually enable Vehicle-to-Grid and Vehicle-to-Home), meaning efficiency exceeds 94 % and the car can export almost its entire usable battery capacity as clean 240 V power.
Real-world range impact example from tonight’s demo:
- 2024 Model Y Performance with 82 kWh pack
- Ran 5.2 kW average load for 2 hours 45 minutes
- Consumed only 14.3 kWh → ~42 miles of range used
- Still showed 68 % battery remaining after cooking dinner and charging all devices
Comparison vs Traditional Gas Generators & Competitor Solutions
| Feature | Tesla 240V Adapter | Ford F-150 Lightning Pro Power | Rivian R1T Camp Power | Honda 3,000 W Gas Generator |
|---|---|---|---|---|
| Max Power | 9.6 kW continuous | 9.6 kW (with 240V outlet) | 11.5 kW (240V) | ~3 kW |
| Noise | 0 dB | 0 dB | 0 dB | 65–75 dB |
| Fuel/Energy Cost (5 kW × 3 hrs) | $2–$4 (home L2) | $2–$4 | $2–$4 | $18–$25 (gas) |
| Emissions | Zero | Zero | Zero | High |
| Weight of equipment | 4.8 lbs (adapter) | Built-in | Built-in | 100+ lbs |
Availability & Software Requirements
Tesla has quietly enabled the feature via OTA update 2025.44.3.1. Owners who take delivery of a 2025 Model Y this week are reporting the “Powershare Mobile Outlet” menu already appears under Controls > Charging.
Current waitlist on Tesla’s online shop shows 18,000+ pre-orders within hours of the video going live.
The era of the gasoline generator at campsites and disaster-response zones may finally be coming to an end. With this $450 adapter, any new Tesla Model Y becomes the most powerful, quietest, and cleanest mobile power station on the market today.
