Grizzl-E Level 2 Charger Full Review

Grizzl-E Level 2 Charger Review

Grizzl-E Level 2 home charger is manufactured by United Chargers and comes in two main versions; a basic Classic charger and a connected “Smart” version for about $80 extra. Both versions top out at 40 amps (~9 kW), and feature identical hardware other than the extra connectivity option. The charger also comes in several color variations, and both NEMA 14-50 and NEMA 06-50 wall connectors.

The Grizzl-E charger is one of the most popular home chargers on the North American market. It represents a great value for a 40 amp charging station, and impressive durability for extreme weather conditions. We recommend this home charger to anyone looking for a balance of value, power, and durability.

Packaging and Installation

The Grizzl-E arrives in an unassuming, single layer, compact cardboard box. Inside is the charger box itself, a bag containing accessories and mounting hardware, and an instruction manual. The charger itself is wrapped in bubble wrap, but this is mainly for cosmetic protection. The aluminum exterior shell of the charger gives this product unmatched durability in a market full of mostly plastic home chargers. 

Despite the careful packaging, our review unit did some with some minor paint scuffs around the edges, and around the screw holes. But this is likely from the manufacturing process, not transportation. A few Amazon reviewers also pointed out paint and finish issues, especially on white units like ours. We are willing to overlook these minor issues because this product is more about utility and value, and less about styling. 

The Grizzl-E comes with a metal mounting plate that is secured to the wall with four screws. Points to Grizzl-E for using durable metal mounting points where many competitors are using plastic. Overall installation is fairly easy, but it is recommended to secure at least one side of the charger to strong studs in the wall. The weight of the charger and the cord may be too much for just drywall holes.

Hardware and Design

We loved the simple and honest exterior design of the Grizzl-E. It’s a painted aluminum enclosure with a single LED indicator light. It is durable and likely cost-effective to manufacture. The Grizzl-E charger is NEMA Type-4 rated, among the best in the industry for water tightness and extreme climate resistance.

There are four hex screws around the perimeter of the device for easy user access. The front-cover is user removable, and a good rubber seal sits around the cover to keep moisture out. The user will only ever need inside access to change the amperage limit of the home charger. Unlike other chargers on the market, it is not possible to set an amp limit from the app. The amperage is configured by hardware dip switches inside the box. We actually see this is a safety benefit because it is less prone to software/app bugs. Hardware dip switches can be used to limit the maximum power supported by the household circuit, and users can make daily adjustments from settings inside their vehicle screens, if needed.

One area where we feel the Grizzl-E comes short is with the included charging cord holder. The single piece plastic design feels cheap, and not very durable. The flat sides of the home charging box also means that it is not possible to wrap the charging cord around the main unit, and the use of an external cord holder is required. However, if the user is not satisfied with the included cord holder, it can be upgraded to a third party J1772 wall holder.

Charging Cord and J1772 Connector

This home EV charger comes with a 24 foot long vehicle cable. While not the longest in the industry, 24 feet is plenty long to reach most car charging ports regardless of parking orientation. The cord itself feels thick, durable but still fairly pliable. Many EV charging cords struggle in the colder winter months when the rubber material hardens in the cold. The Grizzl-E charger is rated for operation between -22F to 122F, so we do not anticipate problems for outdoor charging in cold climates. We will update this review in a few months if that changes,

The J1772 connector is made of hard plastic material with a silver painted release button. We had no trouble sliding this connector into a Tesla charging adapter for this review. We liked how the J1772 connector comes with a detachable cap, for when not in use. This again, helps with weatherproofing the hardware for extremely wet and cold environments.

Connectivity and Software

Grizzl-E do not have their own charging app for managing their home chargers. For the “Smart” version of the Grizzl-E Level 2 charger, the user will need to download the third party ChargeLab app. Integration is easy, but functionality is very basic. The app allows the user to monitor status and schedule charging. There are no charger locking features, like some of the competitors include.

With the ChargeLab app, the Grizzl-E can be configured to only charge during off-peak hours and pause charging outside of that window of time. The app distinguishes between weekday schedules and weekend schedules. However, it appears there is no ability to schedule customized charging times for individual days of the week.


United Chargers has a made winner product with the Grizzl-E. The Grizzl-E Classic is easy to recommend for users looking for a rugged, 40 amp home charging station at a very reasonable price.
