The Grizzl-E Duo Level 2 EV Charger delivers up to 40 Amps of power with two 24-foot premium cables and a NEMA 14-50 plug. Designed for dual vehicle charging, it provides fast, efficient power for two electric vehicles simultaneously. Ideal for home use, offering reliable, high-performance charging.
The Grizzl-E Duo EV Charger is a high-quality, dual-port charger designed for electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs).
Power Output by Configuration
The Grizzl-E gives you four power settings, each matched to a specific circuit size in your home.
The factory default runs at 40A, delivering 9.6 kW of charging power, and requires a dedicated 50A circuit. This is the setting most homeowners aim for because it’s the fastest the unit can go.
If a 50A circuit isn’t available, you can step down to 32A at 7.68 kW, which pairs with a 40A dedicated circuit and still handles overnight charging without issue.
Homes with older panels or limited capacity can run the charger at 24A, putting out 5.76 kW on a 30A circuit. The lowest option is 16A at 3.84 kW, designed for a 20A dedicated circuit, slower, but it gets the job done for drivers who charge daily and don’t need a full battery topped off in a hurry.
Power Sharing Performance
When two vehicles are plugged in simultaneously, the Grizzl-E uses built-in power sharing to distribute the available current between them.
It starts with an even split: the full 40A is shared equally, so each car receives 20A (4.8 kW).
From there, the charger monitors what each vehicle actually needs. If one car finishes charging or pulls back its draw, the leftover current automatically shifts to the other vehicle without any input from you.
One thing to be aware of: when both vehicles are connected, neither one can exceed 32A regardless of what the other is doing. The 32A ceiling lift only works when the second vehicle is physically unplugged, restoring the full 40A to the remaining car.
Everything Else You Need To Know
Made in Canada, the Grizzl-E Duo features a durable NEMA-4-rated metal enclosure resistant to water and fire. It’s designed to withstand harsh outdoor conditions, making it suitable for both indoor and outdoor use. The charger is UL-certified and compatible with all EVs and PHEVs in North America.
Its main competitor, DEWALT EV Chargers, stands out with more rugged, durable, weather-resistant construction and advanced safety features, even though DEWALT currently offers primarily single-port models. Among these, the 40 Amp DEWALT Charger is especially notable. Users comparing the two will appreciate DEWALT’s industrial-grade reliability and smart charging capabilities, making it a strong rival for those who prioritize long-term performance, intelligent charging features, and peace of mind in demanding environments.
With a 240V Level 2 charging speed, it significantly reduces charging time, taking less than 2 hours to charge a plug-in hybrid compared to the 12 hours needed with a standard 120V charger.
One of the standout features of the Grizzl-E Duo is its easy installation. You only need to install a simple 14-50R outlet, saving both on installation costs and space. It is also portable and easily removed from its mounting bracket for relocation. The charger comes with two 24-ft premium J1772 charging cables, making it convenient for various vehicle setups.
The lack of charging lights may not appeal to everyone, but it doesn’t affect the charger’s performance. Overall, the Grizzl-E Duo is a reliable and efficient choice for those who need to charge two EVs at once, offering fast charging, ease of use, and long-term durability.
Grizzl-E Duo EV Charger Versus Other J1772 Chargers
The following chart compares key specifications (charging power, weight, operating temperature range, cable length, and warranty) of the Grizzl-E Duo EV Charger with other EV chargers using the same J1772 connector type (direct competitors).
Grizzl-E Duo NEMA 14-50 Installation
This image depicts the wiring setup for installing a NEMA 14-50R outlet for a Grizzl-E Duo EV Charger. It shows key components, including L1 (Hot 1), L2 (Hot 2), Neutral (N), and Ground (G), along with a 50A double-pole main breaker, a neutral busbar, a ground busbar, and a ground rod. The installation uses 6 AWG 90°C copper wire and ¾” to 1¼” conduit, in accordance with US NEC standards for safe and efficient EV charging.
Compatible NEMA 14-50 Outlets
We have listed compatible NEMA 14-50 outlets for use with the Grizzl-E Duo EV Charger below. These outlets provide a continuous 40A (9.6 kW) charge on a 50A circuit breaker, ensuring safe and efficient performance. Designed for long-term reliability, they support 6 AWG wiring and are built to handle frequent use without risk of overheating
Grizzl-E Duo EV Charger Installation with NEMA 6-50 Outlet
Installing the Grizzl-E Duo 40 Amp EV Charger with a NEMA 6-50 outlet requires attention to specific wiring and breaker requirements. Unlike the NEMA 14-50, the NEMA 6-50R outlet features two parallel hot prongs (with the larger prong on the right) and a horseshoe-shaped ground prong.
Follow these guidelines for proper installation:
- Dedicated Circuit: Connect the outlet to a dedicated 50-amp circuit breaker to support the charger’s maximum 40-amp draw.
- Wire Size: Use 6-gauge wire to safely handle the current.
- Conduit: Protect the wiring by using a conduit with an inner diameter between 3/4″ and 1¼” to ensure safety and proper fit.
Below is a detailed diagram illustrating the wiring setup for the NEMA 6-50R outlet used with the Grizzl-E Duo, including close-up views of the terminal connections and the complete branch circuit running from the breaker panel to the outlet.
Recommended NEMA 6-50 Outlets for Grizzl-E Duo 40 Amp EV Charger
