Grizzl-E Ultimate 48A 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.

The verdict: if you want United Chargers' top-end hardware and you have a normal house, this is the model to buy rather than the 80-amp one. You get the identical cast-aluminum Type 4 enclosure, the identical 25-foot cable and the identical -22 F rating, on a 60-amp circuit instead of a 100-amp circuit, for roughly half the money. Skip it only if your car genuinely accepts more than 11.5 kW and your panel can carry 100 amps continuous -- and both of those have to be true, which for most homes neither is.

The charger in full

What 48 amps gets you

Over a ten-hour overnight window that is 230 to 310 miles depending on the car, which is a full battery for almost everything on the road. The Department of Energy puts typical Level 2 charging at roughly 25 miles of range per hour, so 48 amps is comfortably at the fast end of normal rather than exotic.

The published spec that does not add up

Worth flagging because we will not paper over it. United Chargers publishes the maximum output as 48 A and, separately, publishes the adjustable current steps as 40, 32, 24 and 16 A. The 80-amp Ultimate's step list reads 80, 64, 56, 48, 40, 32, 24, 16 -- so on that model 48 A is a selectable step, and on this one the published list tops out below the model's own rated output.

The likely explanation is that the step list describes the dial-down options below the unit's full rating, with 48 A being the default rather than a step. We are not going to assert that, because the maker does not. If you need a specific derated setting -- say 40 A on a 50 A circuit, which is a common reason to buy a bigger charger and turn it down -- that setting is published and available. If you need something between 40 and 48, ask United Chargers before you buy.

Who should buy it

Against the rest of the 48-amp field, the differentiators are the metal case and the published cold rating. DEWALT's 48 A unit publishes no operating temperature range at all, and several rivals are plastic. If neither of those matters to you, the tier roundup is best 48 amp EV charger. If you are still deciding between tiers, 48 amps vs 80 amps settles it with a panel-first test.

1. Ultimate build quality on a 60 A circuit

Grizzl-E Ultimate 48A

United Chargers · J1772 + NACS · 48 A / 11.5 kW · 25 ft cable

The Ultimate's hardware at the amperage most houses can feed: 48 A and 11.5 kW, hardwired, Wi-Fi and OCPP, in the same cast-aluminum Type 4 case. The catch is what United Chargers publishes about dialing it down -- the adjustable steps stop at 40 A.

What is good

• +48 A on a 60 A circuit, which a normal 200 A panel can usually spare
• +Same cast-aluminum UL Type 4 case and -22 F rating as the 80 A Ultimate
• +25 ft cable, the long end of the range
• +Wi-Fi, a mobile app and OCPP, so it is not locked to one vendor's cloud
• +Offered with either a J1772 or a NACS connector

What is not

• −Hardwire only -- there is no plug-in version of the Ultimate
• −United Chargers publishes adjustable steps of 40/32/24/16 A, so the published step list does not include 48 A itself
• −No ENERGY STAR certification listed, unlike the 80 A Ultimate
• −A J1772 unit needs an adapter on every charge if you drive a NACS car
• −Costs more than the 40 A Grizzl-E Classic for speed many owners will not use

2. A 19.2 kW car and a large service

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

Warranty	3 years, or 5 years chosen at purchase

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.

3. A familiar brand, hardwired

DEWALT 48 A EV Charger (DXPAEV048)

DEWALT · J1772 · 48 A / 11.5 kW · 25 ft cable

A 48 A hardwired charger with a 25 ft cable, an LCD screen and an app, from a brand most garages already trust. Adjustable from 12 A, IP66, CSA certified, three-year warranty.

What is good

• +48 A / 11.5 kW, the top tier a normal 60 A home circuit supports
• +Adjustable from 12 A, a wider floor than most chargers offer
• +25 ft cable with a protective cage and an anti-slip handle
• +An LCD screen on the unit, so basic status does not depend on a phone
• +Scheduling and energy monitoring in a free app, with no subscription
• +A three-year warranty backed by 24/7 technical support, and a national install partner

What is not

• −Hardwired only -- DEWALT's plug-in version is the separate 40 A model
• −DEWALT publishes no operating temperature range for it
• −CSA certified, but DEWALT does not name the standard or publish a file number the way Grizzl-E and Lectron do
• −No ENERGY STAR certification listed, unlike several rivals at this price
• −J1772 only, so a NACS car needs an adapter on every charge
• −Costs more than the 48 A chargers most first-time buyers end up with
