Grizzl-E Classic Connect review

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.

This site has long pointed people who want a charger to behave like an appliance toward the Grizzl-E Classic: a 40-amp box with no app, no account and nothing to update. United Chargers now sells the Classic Connect, which it calls the next-generation Grizzl-E -- built on what it calls the made-in-Canada Grizzl-E design, with the same 40-amp, plug-in idea, with updated electronics, a longer cable and, for the first time on this line, Wi-Fi and an app. We have not tested one. Everything below comes from the product record on United Chargers' own page, linked at the foot of this page, and the arithmetic is shown so you can check it.

The specs

What changed from the Classic

On paper these are the same class of charger: 40 amps, plug-in, built for a garage wall or an exposed driveway. The differences are all in what surrounds that 40 amps.

• The app is the headline. The Classic's case for itself was that it had none; the Connect adds one without changing the output.
• A NACS option. The Classic is J1772 only. The Connect is sold with either connector, which matters as more cars arrive with a NACS port. NACS vehicles.
• A slightly longer cable. 25 ft against the Extreme Edition's 24 ft.
• One plug. The Classic is also sold with a NEMA 6-50 plug; every Connect listing we found uses a 14-50. If your outlet is a 6-50, see chargers for a 6-50.

The app, and what it is actually for

United Chargers describes the Grizzl-E Connect app as the place to view charging statistics, set a charging schedule, control the charger remotely and take part in utility demand-response programs. The first three are what most smart chargers offer. The fourth is the one worth a second look: some utilities pay or credit customers who let them nudge charging away from peak hours. Whether your utility runs such a program is entirely local, so check with them before counting on it.

Two practical notes. The charger connects over 2.4 GHz Wi-Fi, so check the signal where it will be mounted -- a detached garage is often the weak spot. And if your car can already schedule its own charging, the app is a convenience rather than a necessity; the car is usually the more reliable place to set an off-peak window anyway. Is a smart charger worth it covers that question in full.

What 40 amps delivers

United Chargers lists the output as 10 kW; at 240 volts, 40 amps is 9.6 kW, and that is the figure we use. For most single-car households, 40 A finishes an overnight charge with hours to spare. The case for more is a big battery, two EVs or a narrow off-peak window, and the Connect has no answer to that -- it is a 40 A plug-in unit, and there is no hardwired 48 A version. 32 A vs 40 A vs 48 A and the 48-amp picks cover that tier.

The cable, and where to mount it

At 25 ft, the Connect's cable matches the longest on this site's wall units (the Autel MaxiCharger, Wallbox Pulsar Plus and FLO Home X3) and beats the Classic Extreme Edition by a foot. That is enough to reach across a two-car garage from a side wall in most layouts, but measure from the mounting spot to your car's port, not in a straight line, before you buy. Cable length guide.

United Chargers rates the Connect for indoor and outdoor use under UL Type 4 and publishes an operating range of -22 F to 122 F, which covers most of the continental US. It does not publish the cast-aluminum, IP67 construction for the Connect that it does for the Classic, so if a tough case is your reason for choosing a Grizzl-E, the Classic is still the one with that specification in writing. Outdoor chargers.

Who should buy it

• You like the Grizzl-E idea but want an app. Scheduling, statistics and remote control, on the same 40 A, plug-in design.
• Your car has a NACS port. The Connect is sold with a native NACS cable; the Classic is not.
• Your utility runs a demand-response program and you want to take part from the charger itself.
• You are replacing a portable that lives on a 14-50 and want something permanent on the wall. Portable vs wall charger.

Who should skip it

• You wanted a Grizzl-E because it has no app. The original Classic is still sold, and still the no-software choice. Chargers without an app.
• You want 48 A. The Connect is a 40 A plug-in unit. The 48-amp picks.
• Your outlet is a NEMA 6-50. Every Connect listing we found uses a 14-50.
• The charger will sit where 2.4 GHz Wi-Fi does not reach. The app is the point of this model.

1. 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

Alternatives

If you want an app and 48 A, the Emporia Classic and the Wallbox Pulsar Plus both reach it hardwired. If you want the longest cable and a NACS option at up to 50 A, look at the FLO Home X3. If you want Lectron's take on a plug-in-or-hardwired unit with no app and a 23 ft cable, see the Lectron NEXUS. And if you are still weighing the app question itself, the smart charger roundup and the no-app roundup make the two cases side by side.
