Grizzl-E 48A Ultimate Level 2 EV Charger - Fast 11.5kW Home Charging

In this review of the Grizzl-E 48A Ultimate Level 2 EV Charger, the bottom line is simple: this is for homeowners and garage users who want the fastest reliable hardwired Level 2 charger with robust weatherproof construction. The single biggest reason to buy is the raw charging power - up to 48A 11.5kW output that meaningfully shortens home charging times compared with a basic Level 1 unit. The review focuses on build quality, installation approach, smart features and everyday usability.

Key Features

• High output: Up to 48A 11.5kW delivers much faster charging for compatible EVs, reducing overnight and mid-day charging windows.
• Durable enclosure: The heavy-duty UL Type 4 rated aluminum cast case is built to withstand harsh weather for indoor or outdoor mounting.
• Long cable: A 25 ft J1772 charging cable reaches most charge ports without repositioning the vehicle.
• Smart charging: OCPP compatibility and Wi-Fi connectivity let you schedule charging, track power and integrate with third-party apps.
• Safety certified: UL and Energy Star certification plus full electrical protections provide dependable, compliant operation.
• Installation kit included: The package includes a mounting bracket and a hardwire kit with terminal lugs for a simpler hardwired installation.

Who It's For

The Grizzl-E Ultimate 48A is aimed at EV owners who want the most powerful Level 2 home charger available in a rugged, permanently installed unit. It suits people who keep their EVs at home overnight or in a garage and want shorter charge times, robust weather resistance and a long cable for flexible parking.

It is less suitable for renters who need a plug-in portable solution or for users who cannot accommodate hardwiring; this model is hardwire-only. Those seeking the simplest plug-and-play portable cordset should look elsewhere.

Pros & Cons

Pros

• Very fast charging up to 48A that cuts recharge time significantly compared with Level 1 charging.
• Solid metal, weatherproof construction rated UL Type 4 for reliable outdoor installation.
• Good smart features via OCPP and Wi-Fi for scheduling, tracking energy use and app control.
• Includes mounting bracket and hardwire kit, making installation more straightforward for electricians.

Cons

• Hardwire-only configuration limits portability and can complicate installation for renters or DIYers without electrical help.
• The unit's power and full feature set may be overkill for drivers with very short daily ranges who never need faster Level 2 charge speeds.

Specifications
