Expert ScoreRead review

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). It allows you to charge two cars simultaneously, providing up to 40 amps for a single vehicle or 20 amps per car when charging both. The charger automatically adjusts to ensure optimal power distribution between the two ports, increasing the amperage for each car once one is fully charged.

Made in Canada, the Grizzl-E Duo features a durable NEMA-4-rated metal enclosure that is resistant to both 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. With a 240V Level 2 charging speed, it reduces charging times significantly, taking less than two 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 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.
