Mixed connectors

The best EV charger when your two cars use different plugs

One car has the small Tesla-style plug and the other has the big round one. You do not need two chargers, and you probably do not need the most expensive answer either.

How this page is funded: we earn a commission if you buy through our Amazon links, at no extra cost to you. It does not change what we recommend, and we say plainly when the honest answer is to buy nothing. Full disclosure.

The verdict: unless both cars need to be plugged in simultaneously, buy a J1772 charger and one certified J1772-to-NACS adapter. The Grizzl-E Classic is the no-app, cast-aluminum, NEMA 4 unit this site recommends for a first charger anyway, and the Lectron J1772-to-NACS adapter publishes UL 2252 certification with an 80 A rating and temperature monitoring in the body -- far above anything a house will ask of it. If you would rather not have a loose adapter in the household at all, the Tesla Universal Wall Connector builds the adapter into the holster and is the tidiest single-unit answer. If both cars genuinely plug in at once, the Grizzl-E Duo Connect is the two-cable route, with the honest caveat that its 40 amps divides.

First, work out whether you have a problem

A lot of mixed-connector households discover they do not need to buy anything. The Department of Energy's own statement is that every Tesla comes with a J1772 adapter, which means a Tesla parked next to a J1772 car can share a single J1772 charger using the part that shipped in the car. If your household is a Tesla and a Mustang Mach-E, go and look in both trunks before reading any further.

The second question is timing, and it decides more than the connectors do. Two typical days of driving is about 21 kWh, which a 40 A charger replaces in a little over two hours -- so two cars can comfortably take turns across one night on one charger. The best EV charger for two EVs has that arithmetic in full. Simultaneous charging is a convenience, not usually a requirement.

The three routes, priced by what they really cost

How to serve two different plugs from one garage
RouteWhat you buyWho it suitsThe catch
One charger plus an adapterA J1772 charger, and one UL 2252 adapter if the car did not come with oneAlmost everybody -- cheapest, and the charger is a normal chargerAn adapter lives on the connector and can be left behind or mislaid
One dual-connector chargerTesla Universal Wall ConnectorA household that wants nothing loose and nothing to think aboutCosts several times a J1772 unit plus an adapter
One charger, two cablesGrizzl-E Duo Connect, J1772/NACSTwo cars that must both be plugged in overnight40 A total, so roughly 20 A each when both draw at once
Two chargersTwo units plus load management or a second circuitVery high mileage on both cars, or two long-distance commutesThe expensive answer to a problem an adapter solves. Read the load calculation first
The 40 A total figure is United Chargers' own published specification for the Duo Connect, not an estimate. Live prices and the date they were read appear on each buy row below.

Which adapter direction do you need?

This is the part people get wrong, and buying the wrong direction is easy because both products are called "a J1772 adapter". The rule is to name the charger and then the car.

  • J1772 charger, NACS car -- you need a J1772-to-NACS adapter. This is the common case and the one that costs least, because a J1772 wall charger is the mainstream product.
  • NACS charger (or a Tesla Wall Connector), J1772 car -- you need a NACS-to-J1772 adapter. Lectron's is rated 80 A at 240 V with IP67 and UL 2252, and Lectron states plainly that it will not work at a Supercharger, because that is DC and a different part.
  • Either way, buy certified. UL 2252 is the standard for these adapters. An uncertified adapter sits between a 240 V supply and your car's inlet all night.

The best J1772 adapters covers both directions in detail, and EV charging adapters, sorted out is the wider list including the ones that came free with the car.

What the dual-connector units actually give you

Two products solve this inside one box and they solve different problems. Tesla's Universal Wall Connector carries the J1772 adapter in the holster, so the adapter cannot be mislaid and nobody has to fit it in the dark -- one cable, one connector, two car types, 48 A. United Chargers' Duo Connect is the other idea: two separate 25-foot cables, available in a J1772/NACS pairing, so both cars can be plugged in at the same time. The specification to read before buying the Duo is the one United Chargers publishes itself -- 40 A total output, which divides between the two cables when both cars are drawing.

If you are weighing those two specifically, this site has the detail: the Tesla Universal Wall Connector review and the Grizzl-E Duo Connect review. And if your household is NACS-only rather than mixed, the best NACS home chargers is the page for that -- it is a different question, and it has a different answer.

The six picks

1. A two-car, two-connector garage

Tesla Universal Wall Connector

Tesla Universal Wall Connector

Tesla · J1772 + NACS · 48 A / 11.5 kW · 24 ft cable

The Wall Connector with a J1772 adapter built into the holster, so it charges a Tesla and a non-Tesla without anything loose to lose.

What is good

  • Charges NACS and J1772 cars without a separate adapter to store
  • Same 48 A output and four-year warranty as the Gen 3
  • The adapter docks in the holster, so it cannot walk off

What is not

  • Costs more than the NACS-only Gen 3
  • Hardwired only
Published specifications for the Tesla Universal Wall Connector
Maximum output48 A / 11.5 kW at 240 V
ConnectorNACS with an integrated J1772 adapter
Cable24 ft
InstallationHardwired
Warranty4 years

Skip this if: Skip it if both cars use the same connector. You are paying for an adapter you do not need.

2. Harsh weather and no app

Grizzl-E Classic

Grizzl-E Classic

United Chargers · J1772 · 40 A / 9.6 kW · 24 ft cable

A cast-aluminum box with no app, no account and no firmware to update. If you want a charger that behaves like an appliance, this is the one.

What is good

  • Cast aluminum NEMA 4 / IP67 enclosure, built for outdoor mounting
  • No app, no account, no network dependency
  • Amperage is set with physical switches, not software
  • Protections for over-current, over-voltage, ground fault and over-temperature

What is not

  • 40 A ceiling, slower than the 48 A units if your panel can take more
  • No scheduling, so off-peak charging has to be set in the car
  • The cold-flexible 24 ft cable is only on the Extreme Edition
Published specifications for the Grizzl-E Classic
Maximum output40 A / 9.6 kW at 240 V
Adjustable16, 24, 32 or 40 A
ConnectorSAE J1772

3. NACS car, J1772 charger

Lectron J1772 to Tesla (NACS) adapter

Lectron J1772 to Tesla (NACS) adapter

Lectron · J1772 to NACS · 80 A / 19.2 kW

Lets a Tesla or any NACS-port car charge from a J1772 charger. Rated to 80 A, certified to UL 2252, with temperature monitoring built into the body.

What is good

  • Certified to UL 2252, which is the standard written for exactly this device
  • Rated well above any home circuit at 80 A, so it is never the limiting part
  • Temperature monitoring in the body, the failure mode that matters on an adapter
  • Works on any J1772 Level 1 or Level 2 charger

What is not

  • Most owners already have one in the car and do not need to buy anything
  • AC only -- it is not a DC fast-charging adapter
  • One more loose item to keep track of, unless it lives clipped to the cable
Published specifications for the Lectron J1772 to Tesla (NACS) adapter
DirectionJ1772 charger to a NACS (Tesla) port
Maximum current80 A
Voltage240 V AC
CertificationUL 2252
SafetyBuilt-in temperature monitoring
UseAC charging (Level 1 and Level 2)

Skip this if: Skip it if your car came with one. Every Tesla ships with a J1772 adapter, and cars sold with a native NACS port ship with one too -- check the trunk before buying.

4. Two EVs on one circuit

Grizzl-E Duo Connect

Grizzl-E Duo Connect

United Chargers · NACS · 40 A / 9.6 kW · 25 ft cable

Two 25 ft cables on one 40 A plug-in charger, so two EVs can be plugged in at once. The honest catch is in the maker's own spec: 40 A total, and 20 A each when both cars charge together.

What is good

  • Two cars can stay plugged in on one 50 A circuit, with no swapping cables at midnight
  • Two 25 ft cables, the longest on this site, so both bays are reachable
  • Connector pairs to suit a mixed household: J1772/J1772, J1772/NACS or NACS/NACS
  • UL/cUL listed with a published file number, and a UL Type 4 indoor/outdoor rating
  • Wi-Fi scheduling and statistics in the Grizzl-E Connect app, with an indicator light per connector

What is not

  • 40 A is the total, not per car: United Chargers lists 20 A each when two vehicles charge at once
  • Plug-in only at 40 A, so there is no 48 A hardwired version
  • Costs far more than one Classic Connect, which gives a single car the full 40 A
  • Two-car households that charge at different times gain nothing over a single charger
  • 2.4 GHz Wi-Fi only, like the rest of the Connect range
Published specifications for the Grizzl-E Duo Connect
Maximum output40 A total (the maker lists 10 kW)

ConnectivityWi-Fi (2.4 GHz) and the Grizzl-E Connect app
CertificationUL/cUL, file E510712
Warranty3 years, or 5 years chosen at purchase

Skip this if: Skip it if both cars charge at different times -- one cheaper charger does the same job overnight. Check the connector pair before ordering, too: United Chargers builds this in J1772/J1772, J1772/NACS and NACS/NACS, but the live Amazon listing is the NACS-NACS version, so a J1772 car needs the mixed pair ordered elsewhere or an adapter.

5. A J1772 car, a Tesla wall unit

Lectron Tesla (NACS) to J1772 adapter, 80 A

Lectron Tesla (NACS) to J1772 adapter, 80 A

Lectron · NACS to J1772 · 80 A / 19.2 kW

The AC adapter, not the DC one: it lets a J1772 car charge from a Tesla Wall Connector, Destination Charger or Mobile Connector at up to 80 A. Lectron is explicit that it will not work on a Supercharger.

What is good

  • 80 A and 240 V, so it is not the limiting part on any home circuit
  • UL 2252 certification published, which a lot of this category does not have
  • IP67, so an outdoor Tesla Wall Connector is fair game
  • Covers Wall Connectors, Destination Chargers and Mobile Connectors, not just one of the three
  • 5 AWG cable and a temperature sensor, both named on the maker's page

What is not

  • AC only -- it does nothing at a Supercharger, and Lectron states that plainly
  • No warranty term published on the product page; the stated cover is a 30-day return
  • If your automaker sells its own Level 2 NACS adapter, that part comes first
  • One more thing to lose out of the trunk

Weather ratingIP67, indoor or outdoor
SafetyBuilt-in temperature sensor; automaker-approved latch design, per Lectron

Skip this if: Skip it if nobody in reach owns a Tesla connector, or if what you actually want is Supercharger access -- that is a DC adapter and a different part. Skip it too if your automaker sells its own; that part comes first.

6. Grizzl-E toughness, with an app

Grizzl-E Classic Connect

Grizzl-E Classic Connect

United Chargers · J1772 · 40 A / 9.6 kW · 25 ft cable

The next-generation Grizzl-E: 40 A on a NEMA 14-50, a 25 ft cable, a UL Type 4 indoor/outdoor rating -- and, unlike the Classic, Wi-Fi and the Grizzl-E Connect app. Sold with a J1772 or NACS cable.

What is good

  • 25 ft cable, a foot longer than the Classic Extreme Edition's
  • Wi-Fi app with schedules and charging statistics, which the Classic deliberately lacks
  • UL/cUL listed, with a published file number
  • Rated to run from -22 F to 122 F

What is not

  • 40 A ceiling, with no hardwired 48 A version
  • Sold with a NEMA 14-50 plug; the Classic's 6-50 option is not among the Connect listings we found
  • The app needs 2.4 GHz Wi-Fi where the charger is mounted

Warranty3 years; 5-year warranty sold separately

Skip this if: Skip it if you wanted a Grizzl-E precisely because it has no app -- the original Classic is still the no-software choice -- or if you want 48 A. The Classic Connect is a 40 A plug-in unit.

One thing to decide before the electrician quotes

Mixed-connector households are the ones most likely to change again. The industry is moving to NACS, several makers now ship cars with a native NACS port, and a J1772 car bought today may be replaced by a NACS one. That argues for the route that is cheapest to change -- a plain J1772 charger plus adapters -- rather than the route that bakes one answer into the wall. Best NACS home charger and NACS vehicles both cover where the changeover currently stands.

FAQ

Questions people actually ask

Can one EV charger work with both NACS and J1772 cars?
Yes, three ways: a J1772 charger plus a certified adapter, the Tesla Universal Wall Connector with the J1772 adapter in its holster, or a two-cable charger such as the Grizzl-E Duo Connect in a J1772/NACS pairing.
Do I need two chargers for two EVs with different plugs?
Almost certainly not. Two typical days of driving is around 21 kWh, which a 40 A charger replaces in a little over two hours, so two cars can share one charger across a night. The connector difference is an adapter, not a second circuit.
Which J1772 adapter do I need?
Name the charger first. A J1772 charger with a NACS car needs a J1772-to-NACS adapter; a Tesla or NACS charger with a J1772 car needs the opposite. Buy one with published UL 2252 certification either way.
Does the Grizzl-E Duo charge two cars at full speed?
No, and United Chargers publishes why: the unit's output is 40 A total, which divides to roughly 20 A each when two cars draw at the same time. That is still a full overnight charge for two normal days of driving.
Is it safe to leave an adapter on the charger permanently?
With a certified adapter, yes -- Lectron's publish UL 2252, an 80 A rating and temperature monitoring in the body. The risk in this category is uncertified adapters, not adapters as a concept.
