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 — 2 September 2026

The Amazon listing for the Classic is currently unavailable. Our live check on this date returned no buyable offer, so the buy link below may not resolve. United Chargers is still selling the Classic 40A direct from its own store, with stock in several colorways — so this is a lapsed Amazon offer rather than a discontinued product, which corrects the note we published here on 26 August. Nothing about the hardware has changed.

The newer model in the lineup is the Grizzl-E Classic Connect 40A: the same 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. We have now reviewed it — see our Grizzl-E Classic Connect 40A review for what it adds, what it drops, and the ENERGY STAR listing we could not find for it. If the no-app simplicity below is the reason you are here, the Classic is still that charger; if you want a current listing you can buy today, 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

The value pick for someone who just wants reliable overnight charging with no app and no fuss. It's a rugged, cast-aluminum 40A box that does one thing well — and the cold-weather cable is a genuine differentiator in a northern garage.

Strengths

  • 40A / 9.6 kW is more than enough to add a full day's range overnight
  • Rugged cast-aluminum housing, NEMA 4 outdoor rating
  • No account, no app, no connectivity to fail — it just charges

Trade-offs

  • Its Amazon listing read “Currently unavailable” when we last checked (2 September 2026) — United Chargers still sells the Classic direct, but the Amazon buy link may not resolve to a live offer
  • No scheduling or energy monitoring (by design)
  • The default cable is stiff; the cold-weather variant is worth it up north
ConnectorJ1772
Max output40 A

Warranty3 years

Spec note. Ships set for a NEMA 14-50 plug on a 40A circuit. Hardwiring is supported but doesn't raise the 40A ceiling — this is a fixed-40A unit, which is the right amount for the vast majority of overnight charging. Re-checked 2 September 2026: a live availability check returns this Amazon listing as “Currently unavailable”, while United Chargers’ own store still lists the Classic 40A with stock in several colorways — so the product is not discontinued, but the Amazon offer is not currently live. The newer model in the lineup is the Classic Connect 40A, which adds Wi-Fi, 16–40A adjustment and a NACS connector option.

Specs read from the product listing, on July 19, 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

Unlike the adjustable ChargePoint, 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.
