Figure for figure
Tesla’s column is the ENERGY STAR record described above. Every other column is read from the manufacturer’s own published specification on the dated visit recorded in our sources. “Not published” means exactly that — we do not fill gaps with estimates.
| Charger | Max current | Power | Cable | Enclosure | Adjustable current |
|---|
| Tesla Wall Connector | 48 A | 11.52 kW | 22 ft (8 AWG) | Not in this record | Not in this record |
| EVIQO NACS 48A | 48 A | 11.5 kW | 25 ft + 40 in input | IP66 / NEMA 4 | 6–48 A, 1 A steps |
| Lectron NEXUS NACS | 48 A | 11.5 kW | 23 ft | IP66 | Not published |
| ChargePoint Home Flex NACS | 50 A | 12 kW | 23 ft | NEMA 3R | 16–50 A in six steps |
| Lectron 40A NACS (portable) | 40 A | 9.6 kW | 16 ft | Not published | Not published |
| Grizzl-E Ultimate 48A | 48 A | 11.5 kW | 25 ft | UL Type 4 | 40 / 32 / 24 / 16 A |
Three things fall out of that table. The cable is where the alternatives win most consistently: 25 feet beats 22, and cable reach is the specification buyers regret most, because the usable route around a garage is never the straight-line distance. The adjustable current rangeis where the gap is widest — two of these chargers can be set to fit a smaller circuit, which is the difference between an install you can afford today and a panel upgrade. And speed is a tie: 48 amps is 48 amps, so at roughly 40 miles of range an hour (11.5 kW at our 3.5 miles-per-kWh reference — our arithmetic) every 48-amp charger here charges your car at the same rate.
If you might not always drive a Tesla
This is the strongest argument for looking elsewhere, and it is worth thinking about before you hardwire anything. A native-NACS charger is the right buy if every car that will ever use this wall takes a Tesla plug. If that is uncertain, there is a cheaper and more flexible route: buy a J1772 charger and a J1772-to-NACS adapter. The adapter is rated to 80 amps and costs a small fraction of any charger here, and it means the wall serves both connector types.
Tesla’s own answer to the same problem is the Universal Wall Connector, whose ENERGY STAR record carries identical electrical figures to the standard unit. The adapter route gets you to the same place from the other direction, and our NACS adapter roundup sorts out which direction you need — a distinction that trips up more buyers than anything else in this category. Our best home chargers for Tesla page ranks that trade directly.
What Tesla’s record does not tell us
We will be explicit about the limits of our own sourcing, because it shapes what this page can fairly claim. The ENERGY STAR record gives current, voltage, power, cord length, conductor gauge, network capability and measured standby draw. It does not give an enclosure or ingress rating, an operating-temperature range, a warranty term, or a list of selectable current steps. Those are the four specifications where the alternatives above publish figures and we have nothing comparable to put beside them — so the table says “Not in this record” rather than implying an absence of the feature. Tesla may publish all four; we simply cannot read its site.
We also publish no price for the Tesla unit, for the same reason we publish no price we cannot verify anywhere on this site: it is not sold through the retailer our price layer checks, so there is no live figure to quote. Every price on this page comes from that daily check with the date attached.
How to choose
Most Tesla households: the EVIQO NACS 48A. It equals the Wall Connector on current and power, gives you three more feet of cable and a published IP66 rating, and the 6-to-48-amp range means it fits whatever circuit you end up with. ENERGY STAR certification also matters if a utility rebate is part of your budget, because many programs require it.
If you want no app and no account:the Lectron NEXUS NACS. The certified-product list makes the case neatly — Lectron lists the NEXUS twice, once with a radio and once without, at 3.02 W and 1.86 W standby. The no-radio build is the one with the fewest things that can stop working. Note that Lectron publishes no adjustable current range for it, so it needs the full 60-amp circuit.
If the app is the point:the ChargePoint Home Flex NACS, with the most mature app of anything here and six published steps from 16 to 50 amps. Fifty amps needs a 70-amp circuit, and the extra two amps over 48 is worth about 1.7 miles of range an hour — so treat the output as a bonus rather than a reason.
If you rent, or you are moving: the Lectron 40A NACS portable. Forty amps on an existing NEMA 14-50 outlet, no install bill, and it goes in the trunk. A published utility estimate puts installation at $400 to $1,200 on top of the hardware, so this is often the cheapest total route to Level 2 by a wide margin.
If the wall has no roof over it:the Grizzl-E Ultimate 48A, in a cast-aluminum UL Type 4 case published from −22°F to 122°F. The catch we state everywhere: the only child listing Amazon carries for the Ultimate 48A is the NACS output-cable version — which here is an advantage, since that is the plug you want.
Still deciding between connector types? Our NACS home charger roundup is the full field, and Lectron NEXUS NACS versus ChargePoint Home Flex NACS is the head-to-head between two of the picks above.
