Head to head
Grizzl-E Classic vs Classic Connect
Two chargers from the same maker, both 40 amps, both plugged into a 14-50. One has an app. That is very nearly the whole decision.

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.
United Chargers now sells two versions of the same idea, and the names do not help: the Grizzl-E Classic and the Grizzl-E Classic Connect. They charge at the same speed, plug into the same outlet, and carry the same three-year warranty. The Connect adds connectivity, which is exactly what buyers of the original went looking for a charger to avoid.

| Adjustable | 16 A to 40 A | 16, 24, 32 or 40 A |
| How you set it | In the app | Physical switches |
| Connector | J1772 or NACS, chosen at purchase | SAE J1772 |
| Cable | 25 ft | 24 ft on the Extreme Edition |
| Installation | Plug-in, NEMA 14-50 | NEMA 14-50 (also sold with 6-50) |

| Connectivity | 2.4 GHz Wi-Fi, Grizzl-E Connect app | None |
| Certification | UL/cUL, file E510712 | UL certified |
| Warranty | 3 years, 5-year option sold separately | 3 years |
Speed: there is no difference
Forty amps is forty amps. On a 50-amp circuit, both units deliver up to 9.6 kW, which is roughly 30 to 35 miles of range an hour for a typical EV. Neither has a 48 A version, so if your panel can support a 48 A charger and you want that speed, neither Grizzl-E is the answer.
What 40 A gives you overnight
40 A x 240 V = 9,600 W = 9.6 kW
9.6 kW x 8 hours = 76.8 kWh delivered overnight
That is a full charge for most EVs, from nearly empty
The app is the real question
The Classic was bought by people who wanted an appliance: no account, no firmware, nothing to stop working when a server is retired. The Connect adds 2.4 GHz Wi-Fi and the Grizzl-E Connect app, which brings scheduled charging and charging statistics.
That matters most if your utility charges less at night. Without an app, off-peak charging has to be scheduled in the car, which nearly every EV can do. Charging at night covers both routes.
Cable, case and connector
- Cable: 25 ft on the Connect, 24 ft on the Classic Extreme Edition. One foot rarely decides a purchase, but both are long. How much cable you need.
- Case: the Classic's cast-aluminum NEMA 4 / IP67 body is the toughest thing in this class. The Connect carries a UL Type 4 rating, rated from -22 F to 122 F.
- Connector: the Connect is sold with a J1772 or a NACS cable. The Classic is J1772, so a NACS car needs an adapter.
Which one to buy
| If you want | Buy |
|---|---|
| Schedules and statistics on your phone | Classic Connect |
| A NACS cable with no adapter | Classic Connect |
| No account, no app, no firmware | Classic |
| The toughest enclosure of the two | Classic |
| To set amperage without a phone | Classic |
| A 48 A charger | Neither -- see the 48-amp roundup |
Both units
Same maker, same 40 A, same three-year warranty. The app is the difference.
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
| Maximum output | 40 A / 9.6 kW at 240 V (the maker lists 10 kW) |
|---|---|
| Adjustable | 16 A to 40 A |
| Connector | SAE J1772 or NACS, chosen at purchase |
| Cable | 25 ft (7.6 m) |
| Plug | NEMA 14-50 |
| Enclosure rating | UL Type 4, indoor and outdoor |
| Operating temperature | -22 F to 122 F |
| Size | 10.25 x 6.25 x 3.75 in |
| Connectivity | Wi-Fi (2.4 GHz) and the Grizzl-E Connect app |
| Certification | UL/cUL, file E510712 |
| Warranty | 3 years; 5-year warranty sold separately |
Skip this if: Skip it if you wanted a Grizzl-E precisely because it has no app -- the original Classic is still the no-software choice -- or if you want 48 A. The Classic Connect is a 40 A plug-in unit.

2. Harsh weather and no app

Grizzl-E Classic
United Chargers · J1772 · 40 A / 9.6 kW · 24 ft cable
A cast-aluminum box with no app, no account and no firmware to update. If you want a charger that behaves like an appliance, this is the one.
What is good
- Cast aluminum NEMA 4 / IP67 enclosure, built for outdoor mounting
- No app, no account, no network dependency
- Amperage is set with physical switches, not software
- Protections for over-current, over-voltage, ground fault and over-temperature
What is not
- 40 A ceiling, slower than the 48 A units if your panel can take more
- No scheduling, so off-peak charging has to be set in the car
- The cold-flexible 24 ft cable is only on the Extreme Edition
| Maximum output | 40 A / 9.6 kW at 240 V |
|---|---|
| Adjustable | 16, 24, 32 or 40 A |
| Connector | SAE J1772 |
| Cable | 24 ft on the Extreme Edition |
| Enclosure | Cast aluminum, NEMA 4 / IP67 |
| Certification | UL certified |
| Warranty | 3 years |
Skip this if: Skip it if you want scheduled charging or energy tracking in an app. The Classic deliberately has neither.
