When to Buy the Classic

The Grizzl-E Classic is the right choice if you have one EV and no plans for a second. At $399, it is the best value Home EV Charger?" class="internal-link">Level 2 charger on the market. You get 40A charging, a 24-foot cable, and build quality that will outlast your car.

There is no WiFi, no app, no scheduling. Plug it in, it charges. If you have flat-rate electricity (no time-of-use pricing), you genuinely do not need smart features.

When to Buy the Duo

The Grizzl-E Duo makes sense if you have two EVs or plan to add one soon. Instead of installing two separate chargers (requiring two circuits, two breakers, and double the installation cost), the Duo shares a single 40A circuit between two connectors.

When only one car is charging, it gets the full 40A. When both cars charge simultaneously, the Duo automatically splits the power — typically 24A each. This is enough to fully charge both cars overnight.

Cost comparison:

• Two Grizzl-E Classics: $800 + two installations ($400-1,000) = $1,200-1,800
• One Grizzl-E Duo: $599 + one installation ($200-500) = $800-1,100

The Duo saves $400-700 for a two-EV household.

Build Quality (Both Are Excellent)

Both the Classic and Duo share the same rugged construction that makes Grizzl-E famous. Heavy-duty cables, NEMA 4 housing, and operational temperature range of -30°F to 122°F. Both units are built to last a decade of daily use in any climate.

The Missing Features

Neither the Classic nor the Duo has WiFi, an app, scheduling, or energy tracking. If you need these features, look at the ChargePoint Home Flex or Wallbox Pulsar Plus instead.

For owners who just want reliable, affordable charging without complexity, the lack of smart features is actually a selling point — there is nothing to malfunction, no app to debug, no WiFi to troubleshoot.

Our Verdict

One EV: Grizzl-E Classic — unbeatable value at $399. Two EVs: Grizzl-E Duo — saves hundreds on installation with built-in power sharing. Need smart features: Look elsewhere — ChargePoint or Wallbox.

FAQ

Can I upgrade from Classic to Duo later? Not directly — they are different units. You would need to buy a Duo separately. If there is any chance you will add a second EV within the next few years, buy the Duo now.

Does the Duo charge two cars at the same time? Yes, but at reduced speed. The 40A capacity is shared, so each car gets approximately 24A when both charge simultaneously. This is still fast enough for overnight charging.

Is the Grizzl-E Duo better than two separate chargers? For most two-EV households, yes — it is significantly cheaper to install. The trade-off is slower simultaneous charging. If both EVs have large batteries and you need maximum charging speed for both every night, two separate chargers on separate circuits is better.
