Search “Grizzl-E” and you’ll find four different products wearing the same rugged cast-aluminum badge — Classic, Classic Connect, Duo, and Ultimate — with no obvious guide to which one actually fits your garage. Buy the wrong tier and you either overpay for an app you didn’t need or end up without the NACS connector your new EV requires.
Grizzl-E by the numbers
- NEMA 4, IP67-equivalent enclosure — every Grizzl-E charger ships in the same cast-aluminum body, rated (per the manufacturer’s own spec sheet) to a seal equivalent to NEMA 4-to-6 protection against dust, hose-directed water, and ice.
- Four tiers, one connector decision — Classic and Duo ship J1772-only; Classic Connect and both Ultimate models add a NACS connector option, so the NACS-vs-J1772 choice is really a choice of which two tiers to shop.
- 80A / 19.2 kW at the top end — the Ultimate 80A is, per United Chargers’ own launch announcement, the first home Level 2 charger of its kind sold in North America at that output, and charges roughly twice as fast as a standard 40-48A unit.
- Open OCPP support — per a State of Charge ChargerRater review, the Ultimate 80A is currently the only charger in its class with genuine Open Charge Point Protocol compliance, letting it talk to third-party charge-management software instead of locking owners into one manufacturer app.
- 3-year standard warranty, 5-year optional — every Grizzl-E model carries a 3-year replacement warranty from United Chargers, extendable to 5 years for an added fee — a year or two short of Tesla’s 4-year and Autel’s 5-year Pro-tier coverage.
Grizzl-E lineup compared
| Model | Best for | Max output | Connector | Smart app | Price |
|---|---|---|---|---|---|
| Grizzl-E Classic | Best overall / no-frills | 40A / 9.6 kW | J1772 | No | ~$299.99 |
| Grizzl-E Classic Connect | Best smart + NACS value | 40A / 9.6 kW | J1772 or NACS | Yes | ~$349.99 |
| Grizzl-E Duo | Two EVs, one box | 40A shared | J1772 | No | ~$899.99 |
| Grizzl-E Ultimate 80A | Highest output / OCPP | 80A / 19.2 kW | J1772 or NACS | Yes | ~$699+ |
1. Grizzl-E Classic — Best Overall
Grizzl-E Classic 40A
- Cast-aluminum, NEMA 4 outdoor-rated enclosure — among the most physically rugged chargers sold.
- DIP-switch adjustable to 16A, 24A, 32A, or 40A, so one unit fits circuits from 20A to 50A.
- No Wi-Fi, no app, no firmware to update or cloud service to eventually shut down.
- J1772 only — Tesla and other NACS drivers need the Classic Connect or an adapter instead.
Ordering a Grizzl-E this week? A free 30-day Amazon Prime trial gets you two-day shipping on the charger itself and everything else you still need for the install, like conduit and a GFCI breaker.
The Classic is the charger for buyers who never want to think about their charger again. There’s no app to log into and nothing that can be discontinued the way JuiceBox’s cloud was in October 2024 — just a rugged box that delivers exactly the amperage you dial in. It’s the same pick our best home EV charger roundup calls out as the budget option, and it pairs well with a NEMA 14-50 outlet if you’d rather plug in than hardwire.
2. Grizzl-E Classic Connect — Best Smart + NACS Value
Grizzl-E Classic Connect 40A
- Same cast-aluminum body and 40A output as the Classic, plus a Wi-Fi radio and the Grizzl-E Connect app.
- Available with a NACS connector, so Tesla and other NACS-native EVs charge without an adapter.
- Scheduling and usage stats through the app, without the screen or RFID hardware of pricier rivals.
- Still capped at 40A / 9.6 kW — the Ultimate tiers go higher for buyers who want more range per hour.
The Classic Connect is what most buyers actually mean when they ask for a “smart Grizzl-E” — it adds exactly two things over the base Classic (Wi-Fi scheduling and a NACS connector option) for about $50 more, without the touchscreen or RFID card reader that pad the price of an Autel MaxiCharger. If a utility rebate requires an ENERGY STAR-certified, connected charger, this is the cheapest Grizzl-E that qualifies.
3. Grizzl-E Duo — Best for Two EVs
Grizzl-E Duo
- Two J1772 cables from a single cast-aluminum enclosure — charge two cars off one circuit.
- Automatically splits its shared 40A output between both ports when both cars charge at once.
- Same NEMA 4 rugged build as the Classic, so it holds up to outdoor, two-bay carport mounting.
- No app or power-sharing negotiation — the split is hardware-only, and there's no NACS option yet.
The Duo is the tidiest one-box answer for a two-EV household that doesn’t want two circuits or two wall mounts. Both cars share roughly 24A each when charging simultaneously and the full 40A when only one is plugged in — see our best dual EV charger guide for how that trade-off compares against running two separate power-sharing units like a pair of Wallbox Pulsar Plus chargers.
4. Grizzl-E Ultimate 80A — Best for Highest Output
Grizzl-E Ultimate 80A
- 80A / 19.2 kW output — roughly double a standard 40-48A Level 2 charger's delivered power.
- Genuine OCPP (Open Charge Point Protocol) compliance, a rare feature that lets it connect to third-party charge-management software instead of one locked-in app.
- Available in J1772 or NACS connector versions, same cast-aluminum NEMA 4 build as the rest of the lineup.
- 80A needs a 100A dedicated circuit — confirm your panel has the headroom before buying.
Most homes don’t need 80A — a 48A charger already adds roughly 35-44 miles of range per hour to a typical EV overnight. The Ultimate 80A earns its place for larger-battery EVs, multi-EV households running one very fast charger instead of two slower ones, and anyone who wants OCPP’s vendor independence over the closed apps that run ChargePoint, Emporia, and Autel’s chargers. A 48A Ultimate model also exists at a lower price for buyers who want the OCPP feature without the 80A headroom requirement.
How Grizzl-E compares to ChargePoint, Emporia, and Wallbox
| Charger | Price | Max output | Connector | Smart platform | Buy it if |
|---|---|---|---|---|---|
| Grizzl-E Classic | ~$299.99 | 40A / 9.6 kW | J1772 | None | You want the cheapest rugged charger with nothing to break |
| ChargePoint Home Flex | ~$549 | 50A / 12 kW | J1772 or NACS | Cloud app | You want the most mature app ecosystem |
| Emporia Classic | $429 / $479 | 48A / 11.5 kW | J1772 or NACS | Cloud app | You want the most amps per dollar with power sharing |
| Wallbox Pulsar Plus | ~$649-$699 | 48A / 11.5 kW | J1772 or NACS | On-device | You want power sharing that survives an internet outage |
| Grizzl-E Ultimate 80A | ~$699+ | 80A / 19.2 kW | J1772 or NACS | Open OCPP | You want the highest output and vendor-independent software |
Grizzl-E’s whole lineup sells on the same premise: a cast-aluminum enclosure that’s survived independent freeze and hose tests, at prices consistently below ChargePoint, Emporia, or Wallbox for comparable output. What it trades away depends on the tier — the Classic gives up any app at all, and even the Connect and Ultimate models run a leaner feature set than Autel’s touchscreen-and-RFID approach. For a buyer who mainly wants amps and durability rather than a polished app, that’s a fair trade.
How to pick the right Grizzl-E
- Start with the Classic unless you specifically need Wi-Fi or NACS. It’s the cheapest way to full 40A charging and there’s nothing to maintain.
- Go Classic Connect for a utility rebate or a NACS-native EV. Both require the small step up from the base Classic.
- Choose the Duo only if two EVs must share one box. Two separate power-sharing chargers cost more but keep full speed available to whichever car is charging alone.
- Reserve the Ultimate 80A for panels with real headroom. Confirm a 100A dedicated circuit is feasible before paying for output you can’t legally draw.
- Check your utility’s rebate list before choosing a connected model. Programs commonly pay $250-$1,000 and require ENERGY STAR certification, which the Connect and Ultimate tiers carry.
Verdict
The best Grizzl-E EV charger for most homes is the Classic 40A at around $299.99 — rugged, simple, and fast enough for any overnight charge. Step up to the Classic Connect (~$349.99) for Wi-Fi scheduling and a NACS option, choose the Duo (~$899.99) for a single box that charges two EVs, and reach for the Ultimate 80A if your panel can support 100A and you want the rare open OCPP platform. Whichever tier you pick, Grizzl-E’s real differentiator against ChargePoint, Emporia, and Wallbox isn’t a feature list — it’s a cast-aluminum body built to outlast all of them.
