Grizzl-E Classic Review

The no-app, rugged 40A value pick — why a fixed-amperage charger that just delivers power is the right call for most single-EV homes.

Availability update — 5 September 2026

The Grizzl-E Classic is no longer sold on Amazon, so the buy button on this page now points at the Classic Connect instead. Our live check on this date returned “Currently unavailable” with no offer, and a brand-wide search returned no Classic listing under any other product number — only the Classic Connect and the Duo Connect. We have removed the dead buy link rather than leave you clicking through to a page you cannot order from.

This is an Amazon availability change, not a discontinuation: United Chargers still lists the Classic 40A on its own store, so if the no-app simplicity described below is exactly what you want, buying direct from the manufacturer is still the way to get it. Nothing about the hardware has changed, and the review below stands as written.

The current model in the lineup — and what we now recommend to anyone who wants this charger from Amazon — is the Grizzl-E Classic Connect 40A: the same made-in-Canada plug-in box and the same UL Type 4 metal enclosure, now adjustable from 16A to 40A, with Wi-Fi and the option of a NACS connector. It is the pick shown below. Read our full Grizzl-E Classic Connect 40A review for what it adds, what it drops — the forced Wi-Fi is a real trade against this line’s whole reputation — and the ENERGY STAR listing we could not find for it. If you would rather compare the whole field first, start with our home charger roundup.

The Grizzl-E Classic is the charger for someone who wants reliable overnight charging and nothing else — no account, no app, no connectivity to drop. It’s a rugged, cast-aluminum 40A box that does one thing well, and for a single-EV home that’s often exactly the right amount of charger. It also tends to be the cheapest way to get a genuine, well-built 40A Level 2 unit.

Grizzl-E Classic Connect 40A (J1772)

Grizzl-E Classic Connect 40A (J1772)

The Grizzl-E Classic with a radio in it: the same made-in-Canada metal box, the same UL Type 4 indoor/outdoor rating and the same 25 ft cable, now with Wi-Fi scheduling and 16–40A adjustment. The adjustment is the upgrade worth paying for, because it lets one charger fit whatever circuit your panel can actually spare. The connectivity is the part to think twice about — this line's reputation was built on having nothing to fail.

Grizzl-E Classic Connect 40A (J1772)

The Grizzl-E Classic with a radio in it: the same made-in-Canada metal box, the same UL Type 4 indoor/outdoor rating and the same 25 ft cable, now with Wi-Fi scheduling and 16–40A adjustment. The adjustment is the upgrade worth paying for, because it lets one charger fit whatever circuit your panel can actually spare. The connectivity is the part to think twice about — this line's reputation was built on having nothing to fail.

Strengths

  • 16–40A adjustable output, so one unit fits a 20A, 30A, 40A or 50A circuit — the outgoing Classic was fixed at 40A
  • UL Type 4 indoor/outdoor rated metal enclosure, made in Canada, rated from -30°C to +50°C
  • 25 ft published cable, which is more reach than most wall chargers at any price
  • Plugs into a NEMA 14-50 outlet, so no hardwiring bill and it moves house with you
  • Wi-Fi (2.4 GHz) with scheduling, charging statistics, remote control and utility demand-response participation
  • 3-year warranty as standard, with a 5-year extension sold separately by the manufacturer

Trade-offs

  • Not in EPA's ENERGY STAR certified-EVSE database as of 2 September 2026, although the Classic it succeeds is — check before counting on a rebate that requires ENERGY STAR
  • Wi-Fi is not optional, on a product line whose whole appeal was that there was no app to fail
  • NEMA 14-50 only: the Classic also offered a NEMA 6-50 plug variant, and that option is gone
  • New for December 2025, so there is far less long-term owner feedback than the Classic has
  • United Chargers publishes “40A 10 kW” while the Amazon listing says 9.6 kW; 40A at 240V is 9.6 kW, so size the circuit off 40A, not off either kW figure

Spec note. United Chargers publishes: AC Level 2, 40A adjustable down to 16A, NEMA 14-50 plug, J1772 or NACS output cable, 25 ft (7.6 m) cord, UL Type 4 indoor/outdoor rating, UL/cUL listing E510712, Wi-Fi 2.4 GHz with the Grizzl-E Connect app, a 3-year warranty, an operating range of -30°C to +50°C and a 10.25 × 6.25 × 3.75 in enclosure. Two caveats we checked rather than assumed. EPA's ENERGY STAR certified-EVSE database lists eight Grizzl-E models under United Chargers Inc. and the Classic Connect is not among them, so we do not repeat the ENERGY STAR claim that appears on one sibling listing. And ENERGY STAR records the outgoing Classic's cord at 24 ft against the same 25 ft marketing figure, so if reach is tight, plan around 24 ft.

Specs read from the product listing, on September 2, 2026. “Not published” means the manufacturer does not state that figure.

Who it’s for

The Grizzl-E suits the set-and-forget owner. If you plug in at night and want a full battery by morning, a 40A charger delivers roughly 30 miles of range per hour — more than 300 miles overnight — and this one does it without asking you to create an account or connect to Wi-Fi. For most people who charge one car at home, that’s the whole job, and paying extra for an app you won’t open is money that could go toward a proper industrial outlet instead.

Build and cold-weather cable

The cast-aluminum housing and NEMA 4 outdoor rating are the standout here: this is a charger built to live on an exterior wall and take weather. The one spec worth paying attention to is the cable — the standard cable is stiff, and if you’re in a cold climate the cold-weather cable variant is worth seeking out, because a cable that stays flexible below freezing is a genuine daily quality-of-life difference in a northern garage.

The trade-off: no smarts

There’s no scheduling and no energy monitoring, by design. If your utility has cheap overnight rates and you want the charger to start automatically at 2am, you either need a car that can schedule charging itself (most can) or a charger with an app — the Grizzl-E won’t do it for you. That’s the one reason to step up to the Emporia or ChargePoint Home Flex, both of which schedule in the app.

Amperage: fixed at 40A

Like the plug-in ChargePoint Home Flex, the Grizzl-E is a fixed 40A unit — hardwiring it doesn’t raise that ceiling. For most drivers that’s the right amount and simplifies the install (a 40A charger needs a 50A circuit). If you specifically want 48A for faster charging and have a 60A circuit, this isn’t the charger; the Emporia is.

Verdict

The Grizzl-E Classic is the honest value pick: rugged, weatherproof, and focused on the one thing a home charger has to do. Buy it if you want a reliable 40A charger with no software in the way, get the cold-weather cable if you live somewhere cold, and put the money you saved toward a good outlet.

Frequently asked questions

Does the Grizzl-E Classic have an app?

No — and that's the point. It has no Wi-Fi, no account and no scheduling. It just delivers power reliably. If you want to schedule charging for cheap overnight rates, use your car's built-in scheduling or choose a charger with an app like the Emporia or ChargePoint Home Flex.

Is 40 amps enough?

For the vast majority of single-EV homes, yes. 40A adds about 30 miles of range per hour — over 300 miles in a typical overnight charge. You'd only need more if you drive very high mileage or have very little time to charge, in which case a 48A charger on a 60A circuit is the step up.

Can I install the Grizzl-E outdoors?

Yes — it's rated NEMA 4 and the cast-aluminum housing is built for it. As with any charger, the circuit and any outlet must be installed by a licensed electrician to code, and an outdoor plug-in install should use a protected, industrial-grade receptacle.

Should I get the cold-weather cable?

If you live somewhere that gets cold, yes. The standard cable is stiff, and a cable that stays flexible below freezing makes plugging in every night meaningfully easier through winter. It's a small upcharge for a daily quality-of-life improvement.
