Grizzl-E Classic vs ChargePoint Home Flex

A deliberately simple machine against a deliberately flexible one. This is a philosophy choice more than a spec comparison.

How this page is funded: we earn a commission if you buy through our Amazon links, at no extra cost to you. It does not change what we recommend, and we say plainly when the honest answer is to buy nothing. Full disclosure.

These two are not really competing on the same axis, which is what makes the comparison useful. One is a piece of electrical equipment; the other is a connected appliance. Both are properly certified and both will charge your car reliably.

The two units

Ranked for a first home charger. Every row jumps to the full write-up below.

Speed: real, and smaller than it sounds

40 A vs 50 A

Grizzl-E at 40 A: 9.6 kW, about 34 miles per hour at 3.5 mi/kWh

Home Flex at 50 A: 12.0 kW, about 42 miles per hour

Over a 10-hour night: 340 miles vs 420 miles

Both are far more than a typical day's driving. The gap matters if you tow, drive long distances daily, or share the charger.

The circuit is part of the price

The Grizzl-E needs a 50-amp circuit; the Home Flex at full output needs 60. On a panel with limited headroom, that difference can be the difference between a straightforward install and a subpanel. Factor it in with the install cost calculator rather than comparing sticker prices alone.

Weather

For an exposed outdoor wall in a harsh climate, the Grizzl-E's cast-aluminum NEMA 4 / IP67 enclosure is the stronger published rating, and its Extreme Edition cold-flexible cable addresses the thing you will actually curse at in January. See the cold weather roundup.

Both units in full

Full specifications and the case against each.

1. Harsh weather and no app

Grizzl-E Classic

United Chargers · J1772 · 40 A / 9.6 kW · 24 ft cable

A cast-aluminum box with no app, no account and no firmware to update. If you want a charger that behaves like an appliance, this is the one.

What is good

  • Cast aluminum NEMA 4 / IP67 enclosure, built for outdoor mounting
  • No app, no account, no network dependency
  • Amperage is set with physical switches, not software
  • Protections for over-current, over-voltage, ground fault and over-temperature

What is not

  • 40 A ceiling, slower than the 48 A units if your panel can take more
  • No scheduling, so off-peak charging has to be set in the car
  • The cold-flexible 24 ft cable is only on the Extreme Edition

Skip this if: Skip it if you want scheduled charging or energy tracking in an app. The Classic deliberately has neither.

2. Homes with an uncertain panel

ChargePoint Home Flex

ChargePoint · J1772 · 50 A / 12 kW · 23 ft cable

The most adjustable unit here. It can be set anywhere from 16 A to 50 A, which makes it the one to buy when you do not yet know what your panel will allow.

What is good

  • Six selectable amperage settings from 16 A to 50 A
  • Sold in both hardwired and NEMA 14-50 versions
  • Rated for indoor or outdoor installation
  • The app is mature and does not require a subscription

What is not

  • 23 ft is a foot shorter than the longest cables in this group
  • The 50 A setting needs a bigger circuit than most panels have spare

Skip this if: Skip it if your circuit is already fixed and you just want the cheapest safe 40 A unit. You are paying for flexibility you will not use.

The verdict

Grizzl-E if your car handles its own charging schedule and you would rather own a machine than a subscription-adjacent device -- especially if it lives outside in a cold place. Home Flex if your panel capacity is uncertain, or you want charging data and scheduling in one app.

FAQ

Questions people actually ask

Is the Grizzl-E or ChargePoint Home Flex faster?
The Home Flex, at up to 50 A / 12 kW against the Grizzl-E's 40 A / 9.6 kW. That is roughly eight miles of range per hour, or 80 miles over a ten-hour night.
Does the Grizzl-E have an app?
No. Its amperage is set with physical switches at installation, which is deliberate and is the main reason people choose it.
Which is better for cold weather?
The Grizzl-E, on published specs: a cast-aluminum NEMA 4 / IP67 enclosure and a cold-flexible cable on the Extreme Edition.
