Grizzl-E Classic Electric Vehicle (EV) Charger Review

Last updated Aug 17, 2022

The Grizzl-E Classic EV home charger is one of the best-built and strongest chargers on the market today. It is manufactured by United Chargers and made in Canada.

Many of the people have the Grizzly-E EV home charging stations installed outside their homes, so they want the cables to be really tough and be able to handle harsh Canadian winters, so this is one solid unit, tougher than most.


Overall Rating: 4.5 out of 5.0

Power Output

The Grizzl-E is one of the powerful power-adjustable Level 2 EV chargers. When you order a Grizzl-E EV charger, you specify which power level (four distinct power levels: 40A, 32A, 24A, and 16A) you want. It will be set and will come at the specific power level.

However, if you need to change the power level, you simply open the front of the cover-up, which is just four screws, and you set the dip switch to the power you want it to deliver.

Power Output of the Grizzl-E Classic EV Charger
Power rating (A) Circuit breaker (A) Power delivery (kW) Charge rate (mph)
40 50 9.6 28-30
32 40 7.7 22-25
24 30 5.8 15-18
16 20 3.9 10-12

Power Delivery

The unit with the maximum current power delivery of 40 amps needs to be on a 50-amp circuit breaker, which can deliver 9.6kW;

If you set the EV charger at 32A, that would need to be on a 40-amp circuit, which would provide 7.7 kW;

If the power level is set at 24A, a 30A circuit breaker would be needed, and 5.8 kilowatts of power can be delivered to the EV; Similarly, 16 amps are on a 20-amp circuit, and 3.9 kW of power delivery could happen.

Besides, you would get different charge rates when setting the charger at different power levels.

At 40 amps, 28-30 miles of range per hour of charging would be added; at 32 amps, 22-25 miles of range per hour; at 24 amps, 15-18 miles of range per hour; at 16 amps, 10-12 miles of range per hour. 

Cable Length and Pliability

United Chargers used to offer both the 18-foot cable and the 24-foot cable. Now the 24-foot cord becomes the standard.

In addition, the premium cable called by them is meant to be for outdoor installations in cold-weather areas.

It’s supposed to be more flexible and a little bit tougher. After being deeply frozen for 14 hours., it easily bent and unbent. The Grizzl-E had a much better performance in terms of cable pliability than the Enel-X JuiceBox charger, but less good than the ChargePoint Home Flex charger.


The Grizzl-E comes with the J1772 charging connector, plasticky, but it seems durable enough.

It can work on all battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) on the market in North America except for Tesla. But if you use a J1772 to Tesla adapter, charging a Tesla with the Grizzl-E EV charger would not be a problem.

Connector Holster

Some electric car chargers come with an attached connector holster and cable management system, so the connector is holstered right into the main unit.

But some chargers don’t. They give you a remote connector holster. That’s the case with the Grizzl-E charger and the Wallbox Pulsar Plus charger.

The package of the Grizzl-E EV charger includes a remote connector holster which helps hold the connector and manage the cable as well.

United Chargers calls the remote connector holster easy EV plug. They claim that it’s much easier to holster the connector with their holster than it is on some of the competing brands.

The holster has a wide tapered opening. No matter how you put the connector in this hole, it will lock. You don’t have to put it perfectly and the taper will guide it into the hole. You don’t even have to hold the connector.

As there are no backlights, the easy EV plug makes it simple. You just have to find the opening, and the connector will snap in.

In contrast, some other companies offer integrated connector holsters and have them backlit, so at night it’s easy to find the connector holster.

Hardwired or Plug-in

The Grizzl-E comes in a plug-in version with a NEMA 14-50 or NEMA 6-50 plug. It’s easy to install. You will need to have a NEMA 14-50 or NEMA 6-50 outlet to plug the Grizzl-E charger in.

The Grizzl-E charger comes with two mounting plates, a base plate that gets attached to the wall and a  second plate that you attach to the back of the charger.

Automatic Restart

The Grizzl-E charger can automatically restart, which means if the chargers are in the middle of a charging session, the power goes out, and then the power is restored, the chargers will re-initialize the charging session and charge the car again.

Smart or Non-Smart

The Grizzl-E is not a smart charger. It just simply charges your electric car.

Weatherproof Rating

The Grizzl-E is one of the most solid chargers on the market today. It has a NEMA 4 rated water and air-tight metal enclosure, which means it can withstand even the pressure of a direct blast of a garden hose.

When you’re in a cold-weather area or an area that gets frequent blowing rainstorms, the NEMA 4 rated chargers are a little bit better than the NEMA 3 rated ones for outdoor installations.

The difference between NEMA 3 and NEMA 4 chargers is that the NEMA 4 rated chargers prevent water from getting in the enclosure even in extreme conditions.

The NEMA 3 rated enclosures are still suitable for outdoor installations, and you don’t have any problem with those if you live in a mild climate area.

However, if you’re in an extreme weather area like some of the northern states that get a lot of blowing snowstorms, or even just the states that get frequent heavy rainstorms with blowing rain, you might want to consider a NEMA 4 rated charger. The Grizzl-E charger would be a great option.
