Grizzl-E Classic Review

Company Background

Grizzl-E is a product line from United Chargers, a Canadian electric vehicle supply equipment (EVSE) manufacturer. Founded as a software company in 2001, United Chargers pivoted to focus on EVSE research, development, and manufacturing in 2019. The Grizzl-E line was launched in early 2020 and has quickly gained a reputation for durability and reliability in the home EV charging market. The company emphasizes rugged construction, North American manufacturing, and straightforward functionality at competitive price points.

Hardware Performance

Independent testing has consistently demonstrated the Grizzl-E Classic’s exceptional reliability in various conditions:

Consistent power delivery at the rated output
Excellent cold-weather performance with successful operation at -22°F
Robust connector that maintains integrity even after thousands of connection cycles
Reliable operation in harsh weather conditions including rain, snow, and extreme heat
Internal temperature management that prevents overheating during extended charging sessions

The Grizzl-E Classic particularly excels in adverse weather conditions (like the harsh Canadian winters), where its industrial-grade components and weather-resistant enclosure provide dependable performance long after consumer-grade units might fail.

Installation Options

The Grizzl-E Classic offers straightforward installation options that accommodate most home setups. The standard configuration comes with a NEMA 14-50 plug for easy connection to a matching outlet, similar to what’s used for electric ranges or dryers. For more permanent installations, a hardwired version is available that connects directly to your home’s electrical panel.

The mounting system consists of a simple bracket that attaches to various wall materials like drywall to concrete. The unit itself weighs approximately 12.5 pounds, moderately light, and measures 10.5” × 6.5” × 3.5”, making it substantial but manageable for most DIY installations. However, as with any EV charger, professional electrician installation is recommended to ensure proper circuit sizing and safety compliance.

Charging Performance

The 40-amp output capability provides impressive charging speeds for home use:

Up to 10 kW charging power
Approximately 28-30 miles of range per hour for most EVs
Full compatibility with most North American electric vehicles
Adjustable power output to match your home’s electrical capacity
Automatic recovery after power outages

In real-world testing with vehicles like the Tesla Model 3, Ford Mustang Mach-E, and Chevrolet Bolt, the Grizzl-E Classic consistently delivered the expected charging rates without thermal throttling during extended sessions. While this unit is not the most powerful in terms of ampage, its reliable performance sets it apart from some competitors that may reduce power during long charging sessions.

Build Quality

We think that the Grizzl-E Classic’s most distinctive feature is its exceptional build quality. United Chargers has designed this unit to top grade specifications including:

Die-cast aluminum enclosure that resists impacts and extreme weather
Heavy-duty internal components rated for commercial use
Premium cable options with enhanced cold-weather flexibility
Robust connector design that withstands repeated use
High-quality internal circuitry with numerous protective features

The unit’s construction quality is immediately apparent when handling it—at 12.5 pounds, it has a substantial feel that inspires confidence in its longevity. The NEMA 4 weather-resistant enclosure is designed to withstand direct water exposure, making it suitable for outdoor installations in virtually any climate.

Cost Considerations

At $399, the Grizzl-E Classic represents excellent value in the Level 2 home charger market. While slightly more expensive than more basic options, its superior durability and reliability justify the modest premium. Additional costs to consider include:

Installation costs (typically $500-$1,200 depending on your home’s electrical setup)
Potential panel upgrades if your home lacks sufficient electrical capacity
Optional accessories like cable management solutions or protective covers

When calculating the total cost of ownership, the Grizzl-E Classic’s 3-year warranty and proven durability suggest lower lifetime costs compared to less robust alternatives that might require replacement sooner.

Safety Features

Safety is important in EV charging equipment, and the Grizzl-E Classic incorporates numerous protective features:

Ground fault protection that automatically detects leakage current
Overcurrent protection to prevent circuit overloads
Overvoltage and undervoltage protection
Temperature monitoring and automatic shutdown if overheating occurs
Auto-restart capability after power interruptions
UL and CSA certification ensuring compliance with rigorous safety standards

These protections work in concert to prevent electrical hazards, protecting both your vehicle and home from potential damage.

Smart Features (or Lack Thereof)

It’s important to note that the Grizzl-E Classic intentionally omits smart features in favor of simplicity and reliability. There is:

No WiFi or Bluetooth connectivity
No smartphone app control
No scheduling capabilities
No energy monitoring or usage tracking
No remote start/stop functionality

For users who prioritize these features, United Chargers offers the Grizzl-E Smart model at a higher price point ($569). However, many customers specifically choose the Classic model for its straightforward operation and fewer potential points of failure compared to connected devices.

Recommendations

The Grizzl-E Classic is ideally suited for:

EV owners who prioritize durability and reliability over smart features and wifi-connectivity
Those in regions with extreme weather conditions
Users with limited technical expertise who prefer simple operation
Households that don’t require detailed charging data or scheduling
Budget-conscious buyers looking for quality construction at a reasonable price

Alternative options to consider:

Grizzl-E Smart for those who want the same durability with added connectivity
ChargePoint Home Flex for those prioritizing smart features and integrations
Emporia for budget-conscious buyers who still want basic smart features
Wallbox Pulsar Plus for those seeking advanced power sharing capabilities

Final Assessment

The Grizzl-E Classic excels by focusing on what matters most in a home EV charger: reliable, consistent performance in a resolute package. While it lacks the connectivity and smart features of premium options, its exceptional build quality and straightforward operation have earned it a loyal following among practical-minded EV owners.

For many users, the absence of smart features is actually a benefit, eliminating future points of failure and privacy concerns. With industry-leading weather resistance, a generous warranty, and competitive pricing, the Grizzl-E Classic represents one of the best values in home EV charging for those who simply want their charger to work consistently for years to come.
