The best EV charger for local control

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: buy the Grizzl-E Ultimate 48. United Chargers publishes OCPP in its own specification table, which means the charger speaks an open protocol that a third party can use if the maker's cloud ever stops answering -- and it is a cast-aluminum UL Type 4 unit rated from -22 F, so the hardware will outlast the software question anyway. If the appeal of local control is really "I do not want to depend on anyone's servers", the cleaner answer is the Enphase HCS-80, which Enphase sells with no connectivity at all and a five-year warranty. And if you want a charger your home network can reach over a cable rather than Wi-Fi, the Autel 80A is the one that publishes Ethernet and RS485.

What "local control" actually means

Three different things get called the same name, and they have different answers.

• An open protocol. OCPP is a published standard for talking to charging hardware. If a charger supports it, something other than the maker's app can start, stop, meter and limit the charge. This is the one you can check on a spec sheet.
• A local network path. Ethernet or RS485 means the charger is reachable on your own wiring instead of over the internet. It does not by itself mean you can speak to it without the maker's cloud, but it removes one dependency.
• No software at all. A charger with no radio and no account cannot be orphaned, cannot lose a firmware update and cannot be reconfigured by anybody. It also cannot schedule anything, which the car can do instead.

Why this is not a theoretical risk

The strongest argument for an open protocol on this site is a page about something that already happened. A major charger brand shut down the servers its app depended on, and owners were left with functional hardware and no way to configure or monitor it. The JuiceBox shutdown and what to replace it with is that story. A charger is a device people expect to own for a decade or more; the software company attached to it is making no such promise.

This is also the honest counter-argument to buying for connectivity at all. Do you need a smart EV charger makes the case that for a lot of households the answer is no, and the best EV charger without an app ranks the units that do not ask. If the only thing you want is cheap overnight electricity, the car's own scheduler achieves it with any charger ever made -- time-of-use charging spells that out.

About Home Assistant specifically

People arrive at this question through home automation, and it is worth being straight about what we can and cannot tell you. Community integrations exist for several of these brands, some of them excellent. None of them is published, supported or guaranteed by the charger maker, they change with firmware releases, and we have not tested any of them. So this page ranks on the thing that is written down and contractual -- the protocol on the maker's specification sheet -- and leaves the integration list to the projects that maintain it.

The six picks

1. Ultimate build quality on a 60 A circuit

Grizzl-E Ultimate 48A

United Chargers · J1772 + NACS · 48 A / 11.5 kW · 25 ft cable

The Ultimate's hardware at the amperage most houses can feed: 48 A and 11.5 kW, hardwired, Wi-Fi and OCPP, in the same cast-aluminum Type 4 case. The catch is what United Chargers publishes about dialing it down -- the adjustable steps stop at 40 A.

What is good

• +48 A on a 60 A circuit, which a normal 200 A panel can usually spare
• +Same cast-aluminum UL Type 4 case and -22 F rating as the 80 A Ultimate
• +25 ft cable, the long end of the range
• +Wi-Fi, a mobile app and OCPP, so it is not locked to one vendor's cloud
• +Offered with either a J1772 or a NACS connector

What is not

• −Hardwire only -- there is no plug-in version of the Ultimate
• −United Chargers publishes adjustable steps of 40/32/24/16 A, so the published step list does not include 48 A itself
• −No ENERGY STAR certification listed, unlike the 80 A Ultimate
• −A J1772 unit needs an adapter on every charge if you drive a NACS car
• −Costs more than the 40 A Grizzl-E Classic for speed many owners will not use

2. A fast charger with no software

Enphase HCS-80

Enphase · J1772 · 64 A / 15.4 kW · 25 ft cable

The no-app option in this tier: 64 A continuous on an 80 A breaker, a watertight NEMA Type 4 case and a five-year warranty. Formerly sold as a ClipperCreek.

What is good

• +Five-year warranty, the longest in this group
• +Watertight NEMA Type 4 enclosure, rated -22 F to 122 F
• +No app, no account and no network dependency
• +Integrated cable wrap and a wall-mounted J1772 holster
• +Published compliance with six UL standards plus ENERGY STAR

What is not

• −64 A, not 80 A, so 15.4 kW rather than 19.2 kW
• −Still needs a dedicated 80 A circuit, which many panels cannot spare
• −No scheduling or energy reporting -- that has to happen in the car
• −J1772 only, so a NACS car needs an adapter
• −The most expensive unit covered here

Published specifications for the Enphase HCS-80

Maximum output	64 A continuous / 15.4 kW
Circuit breaker	Dedicated, 2-pole 80 A
Connector	SAE J1772
Cable	25 ft (7.6 m) or 18 ft (5.5 m), pre-wired

Mounting	Wall or pedestal (pedestal sold separately)
Ground fault	Integral CCID, 20 mA, auto reset
Indicators	Four LEDs: power, charging, power fault, charging fault
Warranty	5 years

Skip this if: Skip it if you want 19.2 kW -- this is 15.4 kW -- or if you want app scheduling. It has no network connection at all.

3. 80 A with an app and access control

Autel MaxiCharger AC 80A

Autel Energy · J1772 · 80 A / 19.2 kW · 25 ft cable

The connected 80-amp charger: 19.2 kW, adjustable all the way down to 6 A from the app, an RFID card reader and a -40 F to 131 F rating. It asks for a 100 A circuit at full output.

What is good

• +19.2 kW, the ceiling of AC Level 2 charging
• +Adjustable from 6 A to 80 A in the app, so one unit fits almost any circuit
• +Built-in RFID card reader, which is rare outside access-control models
• +Published -40 F to 131 F range, the widest of the 80 A units here
• +Long list of published safety standards plus ENERGY STAR certification

What is not

• −80 A continuous needs a 100 A circuit, which most homes cannot spare
• −Derates above 113 F, so a hot garage will not see the full figure
• −Hardwired only, with no plug-in version
• −4G connectivity is an optional extra, not standard
• −Costs far more than the 48 A chargers most households can actually use

Published specifications for the Autel MaxiCharger AC 80A

4. A 19.2 kW car and a large service

Grizzl-E Ultimate 80A

United Chargers · J1772 · 80 A / 19.2 kW · 25 ft cable

The top of AC Level 2: 80 A and 19.2 kW, hardwired, adjustable down through eight settings. The catch is the circuit -- 80 A continuous asks for a 100 A circuit, which most houses cannot spare.

What is good

• +80 A / 19.2 kW is the ceiling of AC Level 2 charging
• +Eight current settings, from 80 A right down to 16 A, so one unit fits almost any circuit
• +25 ft cable and a cast-aluminum UL Type 4 enclosure rated -22 F to 122 F
• +UL listed with a published file number, plus Energy Star certification
• +OCPP support alongside the maker's own app, which is rare at this price

What is not

• −80 A continuous needs a 100 A circuit, which most homes cannot spare
• −Very few cars accept more than 11.5 kW on AC, so the headline figure is unusable for most buyers
• −Hardwired only -- there is no plug-in version
• −Costs far more than the 48 A tier that most households will actually use
• −2.4 GHz Wi-Fi only, like the rest of the Grizzl-E Connect range

Published specifications for the Grizzl-E Ultimate 80A

Maximum output	80 A / 19.2 kW
Adjustable	80, 64, 56, 48, 40, 32, 24 or 16 A
Connector	SAE J1772 or NACS, chosen at purchase
Cable	25 ft (7.6 m)
Installation	Hardwired only
Enclosure	Cast aluminum, UL Type 4 indoor/outdoor
Operating temperature	-30 C to +50 C (-22 F to 122 F)
Enclosure size	10.25 x 6.25 x 3.75 in
Weight	26.46 lb (12 kg), shipped
Connectivity	Wi-Fi (2.4 GHz), the Grizzl-E Connect app, and OCPP
Country of origin	Canada, per United Chargers
Certification	UL, file E510712; Energy Star
In the box	Charger, hardwire kit, mounting cradle, EasyEvPlug
Warranty	3 years, or 5 years chosen at purchase

Skip this if: Skip it unless your car actually accepts more than 11.5 kW and your panel can carry a 100 A circuit. Both have to be true, and for most homes neither is.

5. A tight panel

Emporia Pro EV Charger

Emporia · J1772 · 48 A / 11.5 kW · 25 ft cable

Emporia's 48-amp charger with PowerSmart load management built in: the Vue 3 energy monitor comes in the box, and the charger backs off when the rest of the house is busy. The one to look at when your panel is the obstacle.

What is good

• +PowerSmart load management included, not an add-on
• +Vue 3 energy monitor in the box, for whole-home data
• +Emporia says it works even with older 60 or 100 amp services
• +J1772 or NACS connector options

What is not

• −PowerSmart needs the Vue installed in your panel -- electrician work
• −Costs more than the Emporia Classic, which charges at the same 48 A
• −Only worth it if your panel is the constraint

Published specifications for the Emporia Pro EV Charger

Maximum output	48 A hardwired; 40 A with a NEMA plug
Connector	J1772 or NACS, chosen at purchase
Cable	25 ft
Load management	PowerSmart, standard
In the box	Emporia Vue 3 energy monitor
Installation	NEMA 14-50 plug or hardwired; rear-entry option
Certification	UL certified, GFCI-protected
Warranty	3 years

Skip this if: Skip it if your panel has comfortable room for a full EV circuit. Without that problem you are paying for load management you will not use -- the Emporia Classic charges at the same 48 A.

6. Grizzl-E toughness, with an app

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

Published specifications for the Grizzl-E Classic Connect

Maximum output	40 A / 9.6 kW at 240 V (the maker lists 10 kW)
Adjustable	16 A to 40 A
Connector	SAE J1772 or NACS, chosen at purchase
Cable	25 ft (7.6 m)
Plug	NEMA 14-50
Enclosure rating	UL Type 4, indoor and outdoor
Operating temperature	-22 F to 122 F
Size	10.25 x 6.25 x 3.75 in
Connectivity	Wi-Fi (2.4 GHz) and the Grizzl-E Connect app
Certification	UL/cUL, file E510712
Warranty	3 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.

What none of this changes

Protocol support does not make a charger faster, safer or better value. The amperage still has to match your panel -- how many amps do you need -- and the enclosure still has to match where it will live. Two of the picks here are 80 A class units that need a 100 A circuit most houses do not have; 48 amp vs 80 amp explains why that is usually the wrong tier. Decide the electrical question first and treat local control as a tiebreaker, which is what it is.
