Grizzl-E: The Tank of Home EV Chargers

While competitors like ChargePoint and Wallbox compete on app features and smart home integration, Grizzl-E takes a completely different approach: build a charger so tough and reliable that it outlasts your car. Manufactured in Ontario, Canada by United Chargers Inc., every Grizzl-E charger features a cast-aluminum enclosure with a NEMA 4 weather rating — the same standard used for industrial equipment in mining and construction.

The Grizzl-E lineup has three models: the Classic ($299-$379) for no-frills reliability, the Smart ($459) with WiFi app control, and the Ultimate ($799) with a jaw-dropping 80A output. In this review, we focus on the Classic and Ultimate — the two models that make Grizzl-E unique in the market.

Grizzl-E Classic 40A: The Best Value Rugged Charger

Build Quality: Industrial-Grade Construction

The Grizzl-E Classic’s defining feature is its enclosure. Unlike competitors that use polycarbonate plastic, the Grizzl-E uses a cast aluminum housing rated NEMA 4 — meaning it’s sealed against windblown dust, rain, splashing water, and directed water jets. The unit operates from -30C (-22F) to +50C (122F), making it suitable for everything from Alaskan winters to Arizona summers.

At 22 lbs (10 kg), the Grizzl-E is noticeably heavier than competitors like the Emporia (8 lbs) or ChargePoint (6.5 lbs). That weight comes from the thick aluminum walls and industrial-grade internal components. The J1772 connector clicks into the vehicle with a reassuring mechanical snap, and the 24-foot cable uses a premium jacket that stays flexible even in freezing temperatures.

Charging Performance

At 40 amps and 9.6 kW, the Grizzl-E Classic delivers approximately 28-30 miles of range per hour — enough to fully recharge any EV overnight. Here’s how it performs with popular EVs:

Charge times assume 240V at 40A with 90% charging efficiency.

One of the Grizzl-E’s best features is its adjustable amperage. Internal DIP switches let you set the output to 40A, 32A, 24A, or 16A. If your electrical panel can’t handle 40A (requires a 50A breaker), you can step down to 32A (40A breaker) or 24A (30A breaker) without buying a different charger. This makes it an excellent choice for older homes with limited panel capacity.

Installation: Simplest of Any Charger

The Grizzl-E Classic comes with a NEMA 14-50 plug (or NEMA 6-50, your choice) pre-installed. If you have a 14-50 outlet, installation is genuinely 5 minutes: mount the aluminum bracket to the wall, hang the charger, plug it in. Done. No electrician needed if the outlet already exists.

The mounting bracket uses a quick-release mechanism with a security pin, so you can easily remove the charger and take it with you — useful if you’re renting or want to use it at a second location. For permanent installations, the bracket’s anti-theft design keeps the charger secure.

What the Grizzl-E Classic Doesn’t Have

It’s important to be clear about what you’re giving up by choosing the “dumb” Classic over smart chargers:

• No WiFi — no app, no remote monitoring, no scheduling
• No energy tracking — you won’t see kWh usage or cost estimates
• No load management — can’t automatically reduce amperage when other appliances draw power
• No smart home integration — no Alexa, no Google Home
• No TOU rate optimization — can’t automatically charge at the cheapest electricity rate

If you need any of these features, consider the Grizzl-E Smart ($459) or a competitor like the ChargePoint Home Flex.

Grizzl-E Ultimate 80A: The Fastest Level 2 Charger You Can Buy

The Grizzl-E Ultimate is a different beast entirely. At 80 amps and 19.2 kW, it’s twice as powerful as the Classic and delivers approximately 60 miles of range per hour. This is the fastest Level 2 charger available for residential use — faster than the Tesla Wall Connector (48A), faster than the ChargePoint Home Flex (50A), and faster than anything else on the market.

Who Needs 80A Charging?

Honestly, most people don’t. A 40A charger fully refills any passenger EV overnight. But 80A makes sense if:

• You drive a long-range EV with a massive battery (Rivian R1T 135 kWh, Ford F-150 Lightning 131 kWh, Lucid Air 118 kWh) and need a full charge in under 8 hours
• You have two EVs and share one charger — 80A can partially charge both in the time a 40A charger charges one
• You’re a ride-share driver (Uber/Lyft) who needs maximum range recovery between shifts
• You have a 100A dedicated circuit available and want to future-proof

Ultimate Installation Requirements

The Grizzl-E Ultimate requires a 100A dedicated circuit breaker and must be hardwired (no plug option). This means professional installation is mandatory. Most homes will need a panel upgrade to support a 100A EV circuit, which can cost $2,000-$5,000 depending on your panel and local code requirements. The charger itself is $799, but total installed cost will typically be $2,800-$5,800.

For context, the federal tax credit covers 30% of equipment + installation costs (up to $1,000), so your net cost could be $1,800-$4,800 after the credit.

Ultimate Charging Speed Comparison

As you can see, the Ultimate halves charge times for large-battery EVs — a game-changer for truck and SUV owners who drive long distances daily.

Safety Features

Grizzl-E takes safety seriously — the unit carries UL Full Testing and Certification (UL E510712), ENERGY STAR certification, and IP67 water resistance. Built-in protections include:

• Overcurrent protection — shuts down if current exceeds safe limits
• Overvoltage protection — protects against voltage spikes
• Undervoltage protection — prevents brown-out damage
• Ground fault protection (GFCI) — built-in, no external GFCI needed
• Over-temperature protection — derates or shuts down if internal temp exceeds limits
• Missing diode detection — prevents charging if the connector diode is faulty
• Self-monitoring and recovery — automatically recovers from transient faults
• Power outage recovery — resumes charging when power returns after an outage

These are the same protection circuits found in premium chargers — Grizzl-E simply includes them at a lower price point.

Frequently Asked Questions

Is the Grizzl-E Classic better than the Emporia?

It depends on your priorities. The Grizzl-E Classic has a more durable cast-aluminum enclosure and adjustable amperage, but only delivers 40A (vs Emporia’s 48A) and has no WiFi or app. The Emporia costs the same ($299) but offers more power and smart features. Choose Grizzl-E for durability, Emporia for features. See our Emporia vs ChargePoint comparison for more context.

Can the Grizzl-E Classic charge a Tesla?

Yes, with a J1772-to-NACS adapter. Most new Tesla vehicles include this adapter, or you can purchase one separately for about $50. The Grizzl-E’s 40A output charges a Tesla Model Y from 0-100% in about 7 hours 50 minutes.

Does the Grizzl-E work in extreme cold weather?

Yes — the Grizzl-E is tested to operate from -30C (-22F) to +50C (122F), which is wider than any competitor. The premium cable jacket stays flexible in freezing temperatures, unlike some competitors whose cables become stiff and difficult to handle in winter. This makes it the best choice for EV owners in northern climates.

What’s the difference between Grizzl-E Classic, Smart, and Ultimate?

The Classic ($299) is a no-frills 40A charger with no WiFi. The Smart ($459) adds WiFi app control, scheduling, and energy monitoring to the same 40A platform. The Ultimate ($799) doubles the output to 80A/19.2kW but requires hardwiring and a 100A circuit. All three share the same NEMA 4 cast-aluminum enclosure.

Does the Grizzl-E qualify for the federal tax credit?

Yes, both the Classic and Ultimate qualify for the 30% federal tax credit under the Inflation Reduction Act (up to $1,000). The Classic’s credit is about $90-$114 (30% of $299-$379), and the Ultimate’s credit is about $240 (30% of $799). Installation costs may also qualify if the charger is hardwired.

How long is the Grizzl-E warranty?

The standard warranty is 3 years. Grizzl-E offers an optional 5-year extended warranty for an additional cost. Refurbished units come with the same 3-year warranty. The aluminum enclosure is designed to last 10+ years in outdoor conditions.

Can I adjust the amperage on the Grizzl-E without an app?

Yes — the Grizzl-E Classic and Ultimate use internal DIP switches to set amperage. You’ll need to open the enclosure (requires removing screws) and adjust the switches to select 16A, 24A, 32A, or 40A (Classic) or up to 80A (Ultimate). This is a one-time setup — you won’t change it frequently.
