Grizzl-E Ultimate 80A review

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.

Every other charger on this site tops out at 48 or 50 amps, because that is what a normal house and a normal car can use. The Grizzl-E Ultimate exists for the small number of households where neither of those is the limit. We have not tested one. Everything below comes from United Chargers' own product record, and the arithmetic is shown so you can check whether it applies to you.

The Ultimate in full

The first condition: a 100-amp circuit

Read that second line twice. A 100-amp circuit is not an upgrade to an existing EV circuit -- it is a significant share of most homes' entire service, and it will not survive a load calculation in an average house without a service upgrade. Load calculation is the page that tells you whether this conversation can even start.

The second condition: a car that can take it

The Department of Energy puts AC Level 2 equipment in a range from 2.9 to 19.2 kW, and this charger sits at the very top of it. But the car decides. Its onboard charger converts AC to DC, and that converter is the ceiling -- a car rated for 11.5 kW draws 11.5 kW from an 80 A charger exactly as it would from a 48 A one.

So look up your own car's AC charging rating before considering this tier. If it is 11.5 kW or less -- which covers most EVs sold -- the Ultimate delivers nothing a 48 A charger would not. How many amps you need covers matching the charger to the car.

The eight settings are the real feature

Here is the part that makes the Ultimate more interesting than its headline: it adjusts to 80, 64, 56, 48, 40, 32, 24 or 16 amps. That is a wider range than anything else covered here, and it means the same unit suits a 100 A circuit today and a 50 A circuit in the next house.

Build, weather and certification

• Cast aluminum with a UL Type 4 rating, which is the Grizzl-E family trait and the reason these turn up on exposed walls.
• -22 F to 122 F published range, so cold is not the constraint. Cold-weather chargers.
• UL listed under file E510712 and Energy Star certified -- a published file number, not a claim of compliance. Certification wording.
• 25 ft cable, matching the longest on this site. Long-cable chargers.

OCPP, which is unusual here

Alongside the Grizzl-E Connect app, United Chargers lists OCPP support. That is the open protocol commercial networks speak, and on a home charger it mainly means the unit is not locked to one company's servers for its lifetime -- a genuine answer to the standing worry about app-dependent chargers. Do you need a smart charger covers that trade in general.

Who should buy it

• A truck or large EV with a 19.2 kW onboard charger, and the panel capacity to feed it.
• A new build or a service upgrade already in progress, where a 100 A circuit can be planned in. Roughing in for a new build.
• A household that wants one charger for several circuits over time, given the eight settings.
• Anyone who wanted a Grizzl-E and also wants an app and OCPP, and does not mind hardwiring.

Who should skip it

• Almost everyone. If your car accepts 11.5 kW, the 48-amp tier is the same charging speed for less money.
• Anyone on a 100 or 150 A service. The circuit is not there. 100-amp panels.
• Anyone who wants a plug-in charger -- this is hardwired only. Plug-in chargers.
• Anyone whose real problem is panel capacity, where a load-managed charger solves more than a bigger one. Load management.

Grizzl-E Ultimate 80A

United Chargers · J1772 · 80 A / 19.2 kW · 25 ft cable

The top of AC Level 2: 80 A and 19.2 kW, hardwired, adjustable down through eight settings. The catch is the circuit -- 80 A continuous asks for a 100 A circuit, which most houses cannot spare.

What is good

• +80 A / 19.2 kW is the ceiling of AC Level 2 charging
• +Eight current settings, from 80 A right down to 16 A, so one unit fits almost any circuit
• +25 ft cable and a cast-aluminum UL Type 4 enclosure rated -22 F to 122 F
• +UL listed with a published file number, plus Energy Star certification
• +OCPP support alongside the maker's own app, which is rare at this price

What is not

• −80 A continuous needs a 100 A circuit, which most homes cannot spare
• −Very few cars accept more than 11.5 kW on AC, so the headline figure is unusable for most buyers
• −Hardwired only -- there is no plug-in version
• −Costs far more than the 48 A tier that most households will actually use
• −2.4 GHz Wi-Fi only, like the rest of the Grizzl-E Connect range

Skip this if: Skip it unless your car actually accepts more than 11.5 kW and your panel can carry a 100 A circuit. Both have to be true, and for most homes neither is.

What to price against it

Before committing, get two other numbers: a 48 A charger on a 60 A circuit, and whatever your electrician quotes for the 100 A circuit this unit needs. The second number is usually the one that settles it. If the gap is large and your car cannot use 19.2 kW anyway, the 60-amp circuit is where most of this site's readers should land.
