In our previous articles, we introduced the principles and safety of DC discharging, giving Tesla owners a basic understanding of DC V2L adapters. But does the safety of this category mean that every product you purchase is equally safe?
Of course not.
Just like cars—some brands are built to take you across all seven continents, while others are more likely to keep you busy visiting repair shops.
With the WETOX PowerShare D2, we’re confident it can be your most reliable companion.
At first glance, the WETOX PowerShare D2 immediately stands out with a design unlike any other brand. It features a distinctive angular shape with a slightly upward-tilted front panel, positioning the outlets at an ergonomic angle for easier access. Unlike traditional V2L adapters, which often use a boxy design with outlets placed on a 90° vertical surface, the WETOX eliminates the need to bend down or fumble around awkwardly to plug in your devices.
The rear features bold, sculpted contour lines that add visual depth, while the metal handle blends seamlessly into the design—combining style with space-saving practicality.
Good looks are just the icing on the cake—what truly matters is the structural reliability behind it. Every part of the WETOX PowerShare D2 is custom-designed, from the internal circuit boards, chips, and aluminum heat sinks to the copper coils. Each component is housed in its own waterproof and sealed compartment, and the layout is meticulously planned based on thermal management principles.
Such a design enables more efficient use of space. Despite featuring 40% more safety protection components than competing products, the WETOX PowerShare D2 remains compact and lightweight.
Most importantly, since V2L adapters are often stored in vehicles and exposed to high temperatures and constant vibrations, the WETOX PowerShare D2 is built with a reinforced dual-layer frame and precision engineering to ensure long-lasting durability.
When compared to other common competitors on the market, you’ll find that most brands, without exception, rely on a single aluminum alloy sheet bent into a sleeve, with covers simply attached to both ends. In many cases, even the screws are visibly exposed. Whether such a design looks good or not is purely subjective, but it does mean that the internal components lack more comprehensive structural protection.
As a product frequently used outdoors, waterproofing is crucial. The WETOX PowerShare D2 features an IPX5 waterproof rating, allowing you to use it even in heavy rain. Every part of the device, including the charging connector, main unit, and even outlets, is designed to be waterproof. This not only broadens its use scenarios but also provides peace of mind in unexpected situations, such as sudden rain or accidental spills like soda during camping.
Each adapter includes a meticulously crafted PU water-resistant carrying case, while the 5-meter IPX6 waterproof extension cord is available as an optional accessory.The extension cord is fully waterproof and capable of withstanding heavy rainstorms, ensuring safe and reliable performance even in the harshest outdoor conditions.
The DC V2L adapter connects directly to the vehicle's high-voltage system, which makes its internal components the key factor in determining product safety. In terms of communication protocols, the WETOX laboratory is equipped with test vehicles covering all standard interfaces available on the market, ensuring seamless compatibility with Tesla models across different years and versions. Unlike many manufacturers that rely on off-the-shelf protocol modules for simple assembly, WETOX independently develops and codes all communication protocols in strict accordance with international standards.
For high-voltage inversion, the WETOX PowerShare D2 uses power chips from renowned brands and incorporates an advanced intelligent management and detection system. This system features multiple layers of protection, including temperature control, voltage protection, short-circuit protection, leakage protection, power protection, and low-battery protection. It responds within milliseconds, ensuring the highest level of safety for the vehicle, devices, and connected appliances.
Over-Temperature Protection: A temperature probe is placed at the hottest point inside the adapter. When the internal temperature reaches 176℉, the temperature protection is triggered, and the adapter automatically shuts down after overheating.
Over/Under Voltage Protection: If the input voltage is ≤320V, the adapter shuts down or fails to start. Similarly, if the input voltage is ≥480V, the adapter also shuts down or fails to start. This prevents damage to the vehicle when used on an 800V platform or damage to connected appliances when used on a low-voltage platform.
Short-Circuit Protection: When the load current exceeds 50% of the protection current threshold, short-circuit protection is triggered, and the adapter automatically shuts down.
Leakage Protection: If the zero-sequence current between the AC side's L (live) and N (neutral) lines reaches ≥30mA, leakage protection is activated. The output relay disconnects, and the adapter shuts down automatically.
Power Protection: The adapter supports a total power of 3.6kW. If the power draw from any single outlet exceeds 1.8kW, the adapter triggers overload protection and shuts down automatically.
Low Battery Protection: The adapter continuously reads real-time vehicle data. When the state of charge (SOC) falls below 10%, the adapter shuts down automatically to ensure the vehicle retains enough power to reach the nearest charging station.
The arguments above may sound convincing, but at the end of the day, they come from WETOX itself—a manufacturer promoting its own product. No matter how much is said, it can feel a bit like “tooting one’s own horn.” True validation of a product’s safety and reliability comes from automaker recognition.
Unfortunately, Tesla has never certified any third-party brand. However, WETOX has already gained recognition from several other automakers, with official announcements issued directly by their headquarters (not by dealerships).
-
October 2022: WETOX (WeiDian) was designated as the officially recommended brand by Li Auto for the 2020 Li ONE, which lacks a bi-directional OBC.
-
June 2023: WETOX (WeiDian) launched on Buick’s official store, providing V2L solutions for the Buick E4 and E5.
-
August 2023: WETOX (WeiDian) was selected by Cadillac to enable V2L functionality for the Lyriq model during an official event hosted by the automaker.
-
November 2023: WETOX (WeiDian) was listed on Leapmotor’s official store, supporting V2L for the Leapmotor T03 (which lacks a bi-directional OBC across all models) as well as certain configurations of the Leapmotor C11 and C01 that do not include a bi-directional OBC.
-
December 2024: WETOX (WeiDian) became the officially recommended brand by XPeng Motors for V2L on the XPeng MONA M03.
We can be very upfront with you: all NACS DC V2L adapters currently available for the U.S. market that you see online are manufactured in Chinese factories. However, these other brands have never received recognition from any automaker, even in China.
WETOX (WeiDian) specializes in DC V2L adapters, with its GB/T interface products having been proven in the market for over three years and trusted by tens of thousands of real Tesla users. As the largest DC discharge adapter brand in China, WETOX ensures reliability and quality.
In the U.S., aside from offline sales channels, we only support direct sales through official stores and authorized dealers. We do not provide private-label distribution permissions to any third-party shopping platforms, ensuring that Tesla owners enjoy a seamless shopping experience and comprehensive after-sales support.
