The Lectron Tesla to J1772 adapter enables non-Tesla EVs to charge on Tesla destination chargers or mobile chargers, providing a compact and reliable backup.
I’ve been testing EV chargers, adapters, and accessories for years. When it comes to convenience on the road, a Tesla-to-J1772 adapter is one of the most useful tools you can carry, especially if you drive a J1772 EV.
For the past two months, I’ve been using the 48 Amp Lectron Tesla to J1772 adapter at Tesla destination and with mobile and NACs home chargers (Level 1 and Level 2) around Los Angeles. Tesla destination chargers have been popping up everywhere in Los Angeles and California at large, thanks to state funding, federal programs, and private investment. You’ll find them at hotels, shopping centers, and workplaces, places where Tesla connectors are common but J1772 options are often missing.
With the Lectron Tesla to J1772 adapter, you instantly gain access to thousands of extra charging points. That means more flexibility on road trips, peace of mind in areas with fewer stations, and less range anxiety when chargers are scarce. Every J1772 EV owner should keep one in the car.

Compatibility and Charging Limits
The Lectron 48-amp Tesla-to-J1772 adapter is compatible with Tesla Level 2 AC chargers, including Wall Connectors, Destination Chargers, and Mobile Connectors. It works with most J1772-equipped EVs such as Audi, BMW, Chevrolet, Ford, Hyundai, Kia, Nissan, Rivian, VW, and many more.
The “48-amp” rating on the adapter is a maximum capacity. Your car and the charging station will negotiate a safe charging rate, which will be the lowest of three numbers: the adapter’s max rating (48A), the charger’s max output, or your car’s max input.
It’s important to note that this adapter does not work with Tesla Superchargers. SAE J1772 EV charging uses AC charging (Level 1 and Level 2), while Superchargers use DC fast charging. Since these are completely different systems, no simple adapter can bridge the two.
First Impressions
Unboxing the Lectron Tesla to J1772 adapter was simple. It came in a protective box with bubble wrap, nothing fancy, but effective. Setup is as easy as plugging in both ends and charging.
The Lectron Tesla-to-J1772 adapter is a solid, value-focused option rated for up to 48 Amps. The matte black design looks sleek and professional, and the build quality feels excellent with a tight fit, no rattling, and a strong connection.
It’s slightly bigger than the TeslaTap Mini, which we recommend as a more portable Tesla-to-J1772 adapter, but still compact enough to keep in a glove box or frunk. Holding it in hand, I felt confident it could stand up to daily use, all at a price point of around $150, making it a dependable choice for budget-conscious drivers.
By contrast, the TeslaTap Mini is the premium option. It supports up to 60 Amps, offering both higher performance and a more compact design.
The image below shows a side-by-side comparison of the Lectron Tesla-to-J1772 adapter (top) and the TeslaTap Mini (bottom). The Lectron is larger with a curved, durable design, while the TeslaTap Mini is more compact, portable, and features printed instructions for easier use.
The Lectron adapter handles up to 48 Amps at a budget-friendly price, but the TeslaTap Mini takes it further with 60 Amps, a smaller size, and smoother plug-and-play reliability. For frequent travelers, the TeslaTap is worth the upgrade.
My Experience with the Lectron Adapter
I keep the Lectron Tesla to J1772 adapter in my car at all times because it’s proven reliable. On a summer trip, I stayed at the Westin Bonaventure Hotel in Los Angeles, which only had Tesla Level 2 destination chargers available. Without the adapter, I couldn’t have charged overnight. With it, I plugged in and woke up to a full battery by morning. The connections felt solid, charging was steady, and after a year of use, it’s proven to be a dependable backup. Nothing fancy, just reliable.
Performance has been excellent. The release latch gives a clear click when disconnecting, and the connection holds firmly to the J1772 EV socket/inlet. In testing at our EV charger test bench with my Chevy Bolt using the Lectron Level 2 Tesla charger, the adapter stayed cool and worked just as well as at a Public Tesla Destination on Level 2 EV charging speeds, no overheating or drop in performance.
The pin design is another highlight; they use an external spring that presses the contacts firmly against the vehicle connector. In my testing, this gave a more secure connection than other EV charging adapter designs that rely on internal spiral springs. On the J1772 end, the adapter is fully weather-sealed with shrink-wrapped wires to block out moisture. Everything looked clean, durable, and well put together.
At around $150, it’s a compact and dependable solution that gives real peace of mind whenever Tesla destination chargers are your only option.
Who Is It For?
- Budget-Minded J1772 EV Owners: Best choice if you want Tesla destination access for under $200.
- Occasional J1772 EV Users: Handy if you only run into Tesla chargers a few times a year.
- Frequent Users / Business Travelers: If you rely heavily on J1772 EV, spending more on a Tesla-to-J1772 adapter may save time and frustration.
When a Portable Charger Makes More Sense
A Tesla-to-J1772 adapter is useful, but not without drawbacks. Adding extra components to the charging chain can introduce connection errors, voltage drops, overheating, throttled speeds, and long-term wear. Some users also report compatibility issues with certain NACS chargers that have poorly designed Tesla male connectors, as well as occasional handshake failures between the EV and the charging station when negotiating safe power delivery, since an EV charging adapter is just an intermediary with its own electronics and firmware to translate the NACS (Tesla) protocol to the J1772 protocol.
If you don’t already own one, a portable J1772 charger is often a smarter investment. It provides direct, reliable charging without the risks that come with Tesla-to-J1772 adapters, though it comes at a higher cost.
Recommended Option:
Lectron Level 1 and Level 2 EV Charger delivers 12 Amps at 120 volts EV charging speeds when plugged into a standard NEMA 5-15 outlet, and up to 40 Amps at 240 volts EV charging speeds when connected to a NEMA 14-50 outlet. This dual-plug design makes it a versatile and dependable portable charger for both home charging and on-the-road use.
That said, if you already own a portable charger, adding a Tesla-to-J1772 adapter is still a smart way to expand your charging options.
Final Verdict
The Lectron Tesla to J1772 adapter is a reliable, budget-friendly way to unlock thousands of Tesla destination chargers and expand your charging flexibility. It’s compact, well-built, and delivers solid performance for J1772 EV owners on a budget.
That said, an adapter should be viewed as a supplement, not a replacement for a J1772 EV charger. If you don’t already own a portable J1772 unit, investing in one first, such as the Lectron Level 1 / Level 2 Dual-Plug Charger, is the smarter move. It gives you guaranteed charging anywhere, with or without Tesla infrastructure.
If you already have a portable charger, adding the Lectron adapter is an excellent upgrade. For value-focused EV drivers who want dependable access to Tesla destination stations, it’s highly recommended.
