Emporia vs Grizzl-E

The specifications, side by side

Every figure in this table is the manufacturer’s own published number, read on 5 October 2026. Where the two brands measure the same thing differently, both readings are given rather than one being chosen.

48A versus 40A is not the deciding factor

It is the first thing everyone compares and it decides almost nothing. At 240 volts, 48A is 11.5 kW and 40A is 9.6 kW. Across a ten-hour night that is roughly 115 kWh against 96 kWh — call it 400 miles against 335 at a typical 3.5 miles per kWh. Both numbers are several times what an average household drives in a day.

The extra 8 amps only becomes real if twothings are true: your car’s onboard charger can actually accept 48A on AC, and your panel can carry a 60A circuit. Plenty of EVs cap their AC intake well below that — our 40A versus 48A page works through the arithmetic, and the 48A roundupcovers the minority of households where the upgrade genuinely pays. For everyone else, the honest summary is that the Grizzl-E’s 40A is enough and the argument lies elsewhere.

There is one twist worth knowing. The Pro is not a faster charger than Emporia’s own cheaper model — Emporia’s own comparison puts both at 48A. What the Pro adds is load management, and on the plug-in version of the Pro you get 40A anyway, exactly like the Grizzl-E. So if you were planning to buy the Pro and plug it in, you have paid a premium for a charger running at the Grizzl-E’s amperage.

The real difference: who manages your panel

This is the argument, and it is the one case where Emporia does something the Grizzl-E cannot do at any price.

A 48A charger wants a 60A circuit. A 100A service with a range, a dryer, air conditioning and a water heater on it frequently does not have 60 spare amps, and the quoted fix is a panel or service upgrade that costs multiples of the charger. Emporia’s PowerSmart attacks that directly: a Vue 3 energy monitor clamps onto your service mains, reads the whole house in real time, and throttles the car down when the rest of the house is drawing hard. The monitor is included in the box rather than sold as an upsell, which is unusual and genuinely good value if you need it.

Three honest limits on that, though. The throttling depends on the Vue 3 sending load data through Emporia’s cloud, so the thing protecting your panel is a connected service rather than local hardware. The clamps go onto your service mains, which means an electrician still opens the panel — “no panel upgrade” is not “no panel work”. And the dollar savings Emporia quotes for the upgrade you avoid is the manufacturer’s own marketing figure, not an independent estimate. Our load management guide explains the alternatives, including the much cheaper one of simply running less current.

Because that is the Grizzl-E’s answer to the same problem, and it is a good one. The Classic Connect is adjustable from 16A to 40A in the unit itself. If your electrician says you can spare a 30A circuit, you set it to 24A and charge at 5.8 kW — still about 200 miles overnight — with no monitor, no cloud and no second device. You lose the dynamic part: a fixed setting cannot borrow headroom back when the dryer stops. For most households that borrowing is a luxury, because charging overnight already avoids the peaks it would be borrowing from.

Hardwired versus plug-in

The Pro is primarily a hardwired charger, with a rear-entry conduit option that hides the wiring. The Classic Connect is plug-in only, on a NEMA 14-50 outlet, and the NEMA 6-50 option its predecessor offered is gone.

Hardwiring is electrically the better install. There is no receptacle to overheat, and it sidesteps the GFCI conflict that makes plug-in chargers trip breakers: NEC 210.8(A) requires GFCI protection on garage receptacles and NEC 625.54 requires it on receptacles installed for EV charging, and a charger’s own ground-fault protection can fight an external GFCI breaker. Hardwired chargers are not subject to the 625.54 receptacle rule at all. Our plug-in versus hardwired guide has the full case.

Plug-in wins on everything else that is not electrical. You can take it with you when you move, you can swap a failed unit without an electrician, and if the outlet already exists the install cost is zero. Just do not economize on the receptacle — an ordinary 14-50 outlet is built for the intermittent loads of ranges and RVs, not 40A held for eight hours a night, and overheated outlets are a documented failure mode. Our NEMA 14-50 outlet roundup covers the industrial-grade ones worth buying.

Outdoors, cold, and what the ratings mean

Both publish a NEMA 4 / UL Type 4 enclosure, which is a real rating covering windblown dust, rain, splashing and hose-directed water, and a meaningfully stronger claim than the “weather resistant” phrasing unrated units use. On that specification they tie.

They do not tie on cold. Grizzl-E publishes an operating range of −30 °C to +50 °Cand a cast-metal case made in Canada; Emporia does not publish an operating-temperature range for the Pro at all. If the charger is going on an exposed wall in a climate with real winters, that absence matters, and it is the clearest point in Grizzl-E’s favor on hardware. Our outdoor roundup compares the field on exactly this, and cold-weather charging covers what the car does about it.

A plug-in install on an outdoor wall carries the usual caveat regardless of the charger’s rating: the receptacle and its in-use cover must be rated for the location too, and that is the electrician’s responsibility. A charger cover helps on a fully exposed wall.

Certification, and the rebate paperwork

Both brands publish UL listing, and that is the mark that matters most. ENERGY STAR is where both get awkward, in mirror-image ways, and we checked EPA’s own certified-EVSE database rather than taking either listing’s word.

Emporiahas a family record — EMEVSE1, 48A, 11.52 kW, 25 ft of 6 AWG cord, network capability “Yes”, qualified May 2022 — covering fifteen further model numbers including EMC2-A and EMC2-B. The Pro’s own part number on Amazon reads EMC2V3-B. Close, but not identical, and Emporia does not publish which certified model number the Pro carries.

Grizzl-Ehas the opposite problem. EPA’s database lists eight Grizzl-E models under United Chargers Inc., and the Classic Connect is not among them — though the Classic it replaces is. One sibling Amazon listing carries an “Energy Star” claim in its title that EPA’s database does not corroborate for this model, and we are not going to repeat it.

So: if a utility rebate requiring ENERGY STAR certification is part of your budget, verify the exact model number with the program before you order, whichever brand you choose. Programs verify by model number, and several pay enough to change which charger is cheaper. Our certification guide shows how to check a claim yourself in a couple of minutes.

The connector, and why it may end the argument

If your car has a J1772 inlet — which is still most EVs on American roads — both brands serve you and the rest of this page applies.

If your car has a native NACS port, as every Tesla does and as Kia, Hyundai, Ford, GM and others now ship, the practical answer on 5 October 2026 is Grizzl-E, because Emporia’s NACS models were not purchasable on Amazon when we checked and Grizzl-E’s was. You can of course charge a NACS car from a J1772 charger using the adapter that came with it — our J1772-to-Tesla adapter roundupcovers those — but an adapter living permanently on a wall charger is a wear point and a thing to lose. Where a factory NACS handle is available at the same price, buy it. Our NACS home charger roundup is the wider field.

So which one?

Buy the Grizzl-E Classic Connect if you have, or can get, a NEMA 14-50 outlet; if you want a metal box rated for weather you can name; if your car is NACS; or if you are not sure yet what circuit your panel can spare and want a charger that adapts to the answer. It is the cheaper unit and it covers the common case properly. Full detail in our Classic Connect review.

Buy the Emporia Pro if your panel is the constraint and you have been quoted for a service upgrade; if you want whole-home energy monitoring and solar-surplus charging in the same app without a subscription; if you want a clean hardwired install with the conduit hidden; or if your car genuinely accepts 48A and you have the 60A circuit to feed it. Full detail in our Emporia Pro review.

And a third answer, which is the one we would give most often: if neither the panel nor the connector forces your hand, the money is better spent on the installation than on the charger. An industrial-grade receptacle, or hardwiring instead of a plug, buys more reliability over ten years than eight extra amps you cannot use. Our installation cost guide covers where that money actually goes.

One more Grizzl-E worth knowing about if the charger might not stay on this wall: the same generation is sold as a portable, and our Grizzl-E Mini Connect review covers what it costs to have the same enclosure and the same adjustable output in a box you can pack. Emporia has no equivalent product.

One buying note that applies to both. Each brand sells direct as well as on Amazon, and the prices are not always the same. We earn a commission on the Amazon links and nothing on the direct ones, and we would still rather you paid less — check both.
