WETOX D2 | NACS V2L Discharge Adapter for Tesla

The WETOX D2 is engineered for peak conversion efficiency, which you can see validated in our uncut "one-take" test video on our official YouTube channel.

While many V2L devices on the market inadvertently trigger the car's internal battery heater—wasting significant energy and creating a loud, annoying "whirring" noise—our engineering team has leveraged our deep protocol experience to solve this. We are proud to say that WETOX does not trigger the vehicle's battery heating system.

This means you won't waste precious driving range on "phantom heat," and you’ll enjoy a completely silent discharge experience without that constant humming sound.

The Cybertruck and 2025 Model Y Performance are equipped with native V2L hardware and do not require this product. For Model 3, Model Y, Model S, and Model X (NACS), please ensure your vehicle is CCS Protocol Enabled. You can verify this by going to Controls > Software > Additional Vehicle Information on your Tesla’s touchscreen. For more critical details, please refer to the first point in our "Important Notes" section.

The WETOX D2 functions by drawing DC power directly from your Tesla and converting it into stable AC electricity. Runtime is determined by two factors: your vehicle's current State of Charge (SOC) and the wattage of your connected appliances. To protect your mobility, the adapter features real-time SOC monitoring and an automated low-battery safeguard that stops discharge at 10% SOC, ensuring you always have sufficient range to reach a charger.

The adapter is equipped with two NEMA 5-15 outlets, each delivering up to 1.8kW, with a combined maximum output of 3.6kW. This is sufficient for the vast majority of high-power household devices. However, please note that appliances with compressors (such as full-sized refrigerators or air conditioners) often experience a brief power surge during startup. This surge may temporarily exceed the 3.6kW limit, so we recommend checking your appliance specifications before use.

Not at all. The WETOX D2 is engineered to comply with established industry standards, including NACS, ISO-15118, and SAE J3400. It communicates with your vehicle through a sophisticated handshake protocol, allowing the car to voluntarily enable power discharge—no "hacking" or hardware modifications are involved. Tesla batteries are built to handle discharge rates in the hundreds of kilowatts during acceleration; a steady 3.6kW draw is negligible by comparison and will not impact battery health.

The WETOX D2 is a plug-and-play external accessory that requires no modifications to the vehicle's original wiring or internal systems. While warranty policies are ultimately determined by Tesla, global precedents show that major automakers like Nissan, Buick, and Cadillac have explicitly approved the use of DC V2L adapters. Over the past three years, we have sold tens of thousands of units globally with zero reported cases of warranty loss due to our product. However, please be advised that by purchasing this product, you acknowledge and assume the risks associated with using third-party accessories, and the final interpretation of warranty terms belongs to the automaker.

No. Native AC V2L (discharging through a simple plug) requires a Bi-directional On-Board Charger (OBC). Most current Tesla models utilize a unidirectional OBC, which is a physical hardware limitation that cannot be changed via software (OTA). To export power from these vehicles, you must use a specialized DC-to-AC V2L Adapter like the WETOX D2 to bypass the hardware gap.

Furthermore, according to the NACS white paper's roadmap for future V2X integration, it is unlikely that automakers would intentionally disable V2L functionality via OTA updates, as this aligns with the broader move toward energy ecosystem openness. However, final control over vehicle software protocols rests with the automaker. To address this, the WETOX D2 is engineered with OTA firmware upgrade capabilities. Should a vehicle update inadvertently affect V2L compatibility, we have the technical capacity to develop and deploy re-adaptation patches at the fastest possible speed. While we strive for 100% continuous uptime, the use of third-party accessories involves inherent risks; by purchasing the D2, you acknowledge these conditions and the dynamic nature of vehicle software environments.

Currently, many brands on the market only possess "compliance test reports" from third-party labs, which are not the same as official certificates. WETOX is committed to full transparency: we are currently in the formal process of obtaining full UL and CE certifications. These official documents will be published on our website immediately upon completion. In the meantime, our products have already received official endorsements from multiple automakers, which remains one of the most reliable indicators of real-world safety and build quality.

We provide a comprehensive 2-Year Warranty for all users. This includes a "Year 1: Replacement Only" policy—meaning if any hardware issue occurs in the first 12 months, we will immediately send you a brand-new unit instead of making you wait for repairs. For the second year, you are fully covered under our standard professional warranty. We don't charge extra for reliability; it's built into every D2 we make.

This specific model is tailored for the NACS port. For CCS2-standard Teslas, you must purchase our dedicated WETOX D2-CCS2 version. While we guarantee performance for the native D2-CCS2 model, we cannot guarantee stability or safety when using third-party conversion adapters. Regarding future vehicles, we perform continuous compatibility testing; when new models are matched, you can easily update your D2 to the latest firmware via our App to ensure seamless operation.

We are currently in the final stages of mass production and quality optimization. The WETOX D2 is scheduled for its official global launch in June or July 2026.

However, as a special "Early Bird" reward for our community, we will be launching a Kickstarter crowdfunding campaign in mid-to-late April 2026. This will be your exclusive chance to secure the D2 at a significantly discounted pre-launch price. We will post a dedicated announcement and update the links on our website once the campaign goes live. Please stay tuned and subscribe to our newsletter for the latest updates!
