New Device Adds Vehicle-to-Load Capabilities to Tesla Vehicles

There’s a new Kickstarter campaign aimed at Tesla owners, and this one adds a feature many owners have long hoped for — Vehicle-to-Load (V2L) support.

V2L is a system where an EV can supply power to external devices, appliances, or even homes by allowing the energy stored in its battery to flow out through outlets or adapters. Essentially, the EV acts as a power source for devices or the home.

While Tesla only recently added support for V2L with the Cybertruck, most of their vehicles don’t support the new feature. This appears to include the newly designed Model Y. And that’s where this new device comes in.

The VortiPower PowerShare VP20 provides the ability to use your Tesla’s battery as a portable power station - which means you can run other devices right off it.

Tesla doesn’t officially support this capacity, but it is part of the NACS and CCS standards, which means it is technically possible for every Tesla vehicle, not just the Cybertruck. The Vortipower VP20 serves to bridge that technical gap, providing the ability to provide power locally to the Model S, Model 3, Model X, and Model Y.

VortiPower is a new company that is kickstarting support for its vehicle-to-load Tesla adapter and aiming to provide additional adapters with more functionality—including for other CCS vehicles—in the future.

Power Station

You can use this V2L Power Station to power your devices that would normally run off of 120V, 12A wall sockets, which means you’ll be able to run corded power tools, electric stovetops, camping equipment, lights, or just about anything your heart desires.

The VortiPower has two 120V outlets, providing up to 3,500W - that’s 120V at 15A x 2 - across its outlets. While it’s not enough to power a home, it could provide you with much-needed power in desperate situations.

The VP20 can also output 240V from one of its ports - enabling the use of high-power devices that are 240V capable.

While it can’t fully replace a standalone generator, the VP20 does allow you to do some normal tasks that you wouldn’t be able to accomplish without a power source, all while using your Tesla’s massive battery. For reference, a typical portable generator provides about 4,000 to 10,000+ watts of power. However, depending on your needs, it could be a good alternative.

Power Usage

One of the best parts is that EVs include massive batteries. This device will have a fairly minimal hit to your battery per hour - just 3.5kWh. The Model Y Long Range’s battery is 75kWh, so you could run two devices at peak power loads for 10 hours and only use half your vehicle’s battery. Realistically - you’d use this for an hour or two at a time, which means the actual range hit is fairly small.

Pricing / Buy

VortiPower is offering its VP20 at $749 USD as part of its Early Bird Special - with about 130 units left at that price. The price after that will be $899 USD, and VortiPower expects to sell the product regularly after the Kickstarter at $1,700 USD.

They’re also offering some combo packs if you’re interested in multiple devices - and you can check out their pricing on their Kickstarter page. Shipping is included if you’re in the continental United States, but $49 USD anywhere else in the globe.

Specs & Details

The VP20 has an overage output voltage of 110V to 220V - switchable from 120V to 240V modes, with a peak output power of 3,500W. Overall, it's a moderately sized package, coming in at 5x13x9 inches, with a total weight of 15 pounds. You could fit this in the sub-frunk of any Tesla, with its nearly 6-foot-long cable wrapped comfortably around it.

The VP20 has passed the UL458 certification, which means it passes the standards for power conversion equipment for portable applications and recreational vehicles. That means that VortiPower has put some real effort into getting its product vetted and approved, which means it should be safe, stable, and reliable.

V2V Charging

You can also use the Vortishare for vehicle-to-vehicle (V2V) charging. While it would be fairly slow even at 120V/30A - it’d still be helpful in an emergency. It could serve to get a vehicle that’s low or out of battery enough additional charge to limp its way home or to a Supercharger.

Global Support

VortiPower offers both NACS and CCS2 headers. They send out the correct version based on your order region, so you won’t have to worry about getting the correct port for those in Europe or North America. For now, VortiPower is not offering a model for the Chinese market - but they could in the future if their Kickstarter goes well.

Delivery & Kickstarter

VortiPower expects to start production of its units at the end of February, with its first batch shipping in early-to-mid April of this year. 

As a reminder, this is a Kickstarter - so there isn’t a guarantee that you’ll receive a product once you pay them - but VortiPower has already met and achieved their original goal over 10x over, and has kept in continual contact with their backers over the last several months. That said, they seem to have a product that has grabbed a lot of interest.

Tesla’s Stance on V2L

Tesla doesn’t have a positive stance on V2L projects and activities like this - at least unofficial ones that aren’t Tesla’s official PowerShare feature - which is still locked to the Cybertruck. If you’re interested in getting portable battery power outside of your Tesla, you’d be looking at buying a portable battery bank instead - and charging that at home, or using your Tesla’s 120V socket, if it has one.

We’re not sure whether Tesla will be pointing to the use of V2L devices like the VP20 in warranty claims - the VP20 itself uses a negligible amount of power compared to regular driving - and VortiPower claims that they’re working within Tesla’s established parameters to draw power from the High Voltage battery without any hi-jinks or unauthorized modifications.

VortiPower is also offering OTA updates to the device itself via an app - to ensure that it remains compatible with future Tesla Software updates. You can find out more information on their Kickstarter page.

Tesla Intel Atom (MCU 2) and AMD Ryzen (MCU 3): Feature Differences and How to Tell What You Have

By Karan Singh
DirtyTesla

Tesla vehicles are equipped with two main computer systems: the MCU (Media Control Unit), which is responsible for entertainment and display functions, and the Autopilot/FSD Unit, often referred to as the FSD Computer.

Both of these systems have evolved over the years, and they’re commonly referred to by their generation. For example, MCU 2 refers to the second generation of the Media Control Unit. Similarly, the FSD computer is identified by its generation, often called Hardware 3 or Hardware 4, when referring to the third and fourth-generation hardware. More recently, Tesla has started referring to the FSD Computer as AI3 and AI4, but you’ll still hear the older terms used interchangeably.

These two systems are separate and they’re not upgraded at the same time, meaning it’s possible to have a vehicle with MCU 2 and FSD Hardware 3 or MCU 3 with Hardware 3. Some vehicles even feature MCU 1 alongside Hardware 3.

The MCU is not involved with Autopilot or FSD functions—it’s purely for infotainment and in-vehicle features such as vehicle visualization, gaming, maps, and entertainment. It doesn’t impact the capabilities or limitations of Tesla’s autonomous driving systems.

MCU 1 - NVIDIA Tegra 3

MCU 1 was the first media control unit to be introduced in Tesla vehicles, starting back in 2012. This system was used in the Model S and Model X until about April 2018, when Tesla began transitioning to MCU 2.

By the time the Model 3 launched in late 2017, it already included MCU 2. To keep legacy vehicles up to date, Tesla offers an infotainment retrofit that upgrades MCU 1 to MCU 2, which helps make the infotainment unit much more responsive and adds a variety of newer features. Tesla continues to support vehicles with MCU 1, although upgrades are much further apart. In 2024, Tesla added Automatic Emergency Braking (AEB) improvements to vehicles with MCU 1 and even support for FSD V12.3.6 (FSD HW3 required).

Period Offered: 2012 through April 2018

Upgrade: Available as a paid upgrade for Model S and Model X vehicles to go from MCU 1 to MCU 2.

MCU 2 - Intel Atom

The launch of the Model 3 introduced MCU 2, which ran on Intel’s Atom mobile processor. While the Intel Atom was capable at the time, it’s now considered outdated compared to modern standards. As Tesla continues to roll out new features, the limitations of the Atom processor have become more apparent.

There is a notable list of features that are unavailable to vehicles with MCU 2. Although Tesla has optimized software to improve compatibility, not all features have been made accessible to these vehicles.

Period Offered: MCU 2 was offered in 2017 (Model 3) through 2022 (availability differs based on region and model).

Upgrade: As of now, Tesla has not offered an upgrade path or retrofit to transition from MCU 2 to MCU 3, and they’re unlikely to do so.

MCU 3 - AMD Ryzen

In December 2021, Tesla began shipping vehicles with MCU 3, powered by AMD’s Ryzen processor. The first vehicles to feature MCU 3 were the refreshed Model S and Model X, which debuted in 2021. Shortly after, Model 3s and Model Ys were also equipped with MCU 3, and today, all Tesla vehicles, including the Cybertruck, come standard with MCU 3.

This MCU is now the most widely used on the road and is Tesla’s most advanced infotainment processor. It supports impressive 3D visualizations, allows improved gaming on the center touchscreen (and rear screens in equipped vehicles), and offers a host of other capabilities. MCU 3 is also the most feature-complete version, with new features being designed for it first and then backported to MCU 2 or MCU 1 when possible.

Period Offered: The first MCU 3 vehicles were released in December 2021 and is current through today.

Upgrade: MCU 3 is the most current infotainment unit that Tesla offers.

How to Tell - Intel or AMD

Identifying which MCU your vehicle has is straightforward. Simply go to Vehicle Options > Software > Additional Vehicle Information.

In the interface, you’ll find details about whether your vehicle is equipped with an Intel Atom (MCU 2) or AMD Ryzen processor (MCU 3).

MCU 4?

It’s been more than three years since Tesla introduced the AMD Ryzen-powered MCU. Despite advancements, including the transition from FSD Hardware 3 to AI4—and eventually AI5—there’s been no indication of an MCU 4 on the horizon.

The Ryzen processor’s impressive capabilities make it a solid choice for infotainment, and it’s well-suited to serve until there’s another big leap in CPU performance.

While Tesla will upgrade to MCU 4 at some point, it doesn’t seem imminent. Some may argue that Tesla transitioned to MCU 3 too late, leaving vehicles just a few years old feeling outdated. It’s possible Tesla might choose to introduce MCU 4 ahead of the need for more processing power, ensuring that older vehicles can continue to benefit from new software features in the future.

Tesla Expected to Add Turn Signal Stalk Back to Model 3

By Karan Singh

Following the surprising return of the turn signal stalk on the refreshed Model Y, reliable Tesla source Chris Zheng has indicated that the Model 3 will also be receiving a turn stalk. While it initially seems surprising, Tesla mentioned that after receiving lots of customer feedback, there is a lot of demand for the return of the stalk.

For those who appreciate the newer turn signal buttons on vehicles like the Cybertruck, this might come as a surprise. However, the Model 3 and Model Y are designed for the average driver transitioning from a traditional vehicle, making the removal of the turn signal stalk an unexpected and potentially disappointing change.

Turn Stalk

In a conversation during the latest episode of Jay Leno’s Garage, Tesla’s VP of Vehicle Engineering, Lars Moravy, mentioned that Tesla works to remove superfluous parts. In this case, they removed one part too many - and are now bringing back the turn signal stalk.

The updated stalk on the refreshed Model Y is a simplified version of the current Model Y stalk. It doesn’t include multi-stage turn signals (short three flashes versus staying), buttons, or other features. Pure and simple - it is utilized for signaling left and right. The rest of the functions of a traditional stalk remain either on the wheel or on the screen.

Lack of Right ‘Shifter’ Stalk

Tesla has no intent to bring back the right stalk, which is traditionally used to shift the vehicle from Drive to Reverse and Park in Teslas. It’s also used to activate Autopilot. The shifting functionality will remain on-screen or available via the backup by tapping the buttons on the ceiling near the hazards button. Shifting via the dash is intuitive and convenient once you get used to it - and with AutoShift hopefully coming out of Beta sometime soon, this could get even better.

Autopilot activation will remain with a button on the steering wheel. While a vehicle with a single stalk may look a little odd at first, Lars mentioned that Tesla didn’t receive many complaints about shifting or Autopilot use.

Retrofit

Not a Tesla App

We haven’t heard anything about retrofitting the 2024+ Model 3s with the turn signal stalk at this point. However, we imagine this may be a possibility in the future.

However, we can recommend using the wireless Enhauto’s S3XY Stalks if you want to bring a single or dual stalks back to your refreshed Model 3 and don’t want to wait for an official retrofit to arrive. They’re easy to install, well-designed, and reliable.

Other Models

The big question now is: will Tesla bring back the turn signal stalk for its other models? It’s possible, but we doubt it. The Model S and Model X, especially with the Yoke, feel more natural without a stalk, and the button-based signals suit their design. While a stalk might occasionally be useful—like signaling in and out of a roundabout—any future refresh of the S or X would likely include steer-by-wire instead.

On the Cybertruck, the absence of a stalk goes unnoticed, thanks to steer-by-wire, as the squircle steering wheel is never in an awkward position. After thousands of kilometers of daily driving, including plenty of roundabouts, the author can confidently say the signal stalk isn’t missed at all. In fact, the turn signal buttons feel more intuitive, given how the Cybertruck handles.

That said, could Tesla offer signal stalks as an option for those who prefer them? It’s not out of the question. We’ll keep you updated, but in the meantime, let us know—do you prefer turn signal buttons or a traditional stalk?
