This comparison resolves on your car's plug, not on the brand. At the 80-amp tier the Autel MaxiCharger AC Pro is the J1772 unit and the Grizzl-E Ultimate is the NACS one, so a Ford, Hyundai, Kia or GM car points at the Autel and a Tesla or NACS-port car points at the Grizzl-E. Below 80 amps the fight is one-sided in the other direction: the Autel MaxiCharger 40A is the cheaper, better-value single-car charger, because the single-connector Grizzl-E Classic is no longer a live listing and the Grizzl-E you can actually buy at that tier is the two-connector Duo Connect. And before any of it: almost nobody should buy 80 amps at all.
These two brands get compared constantly because they represent opposite philosophies. Autel is a diagnostics company that builds chargers like consumer electronics — Wi-Fi, Bluetooth, app control, OCPP, a holster in the box. Grizzl-E is a Canadian manufacturer that builds chargers like tools: a heavy metal enclosure, a UL Type 4 rating, and scheduling that keeps working when the internet does not. Both are legitimate. They are aimed at different people.
What makes the comparison awkward in 2026 is availability. The charger that made Grizzl-E's reputation, the sealed no-app Classic, is gone from Amazon — its listing is dead and the API rejects the ASIN outright, which is why our Grizzl-E Classic review is kept as a reference page rather than a buying recommendation. So a fair head-to-head has to compare what you can actually put in a cart today.
The short version
- Autel MaxiCharger AC Pro (80A, J1772) — the 80-amp pick for a J1772 car. Up to 19.2 kW hardwired on a 100-amp circuit, with Wi-Fi, app control and a 25-foot cable. The right answer only if your car's onboard charger actually accepts 19.2 kW. Full review.
- Grizzl-E Ultimate (80A, NACS) — the 80-amp pick for a NACS car. The same 19.2 kW ceiling in a UL Type 4 metal enclosure made in Canada, with scheduling that works offline. Native Tesla-style plug. Full review.
- Autel MaxiCharger (40A) — the better value, and the one most people want. 9.6 kW, J1772, a 25-foot cable and a holster included, Wi-Fi and Bluetooth, at a fraction of the 80-amp price. For a single car on a normal panel this is the Autel to buy. Full review.
- Grizzl-E Duo Connect (dual 40A) — the Grizzl-E for two cars. Two 25-foot cables sharing up to 40 amps on one circuit, UL Type 4, NEMA 14-50 plug. It is not a competitor to a single-connector 40-amp charger on price; it is a competitor to installing a second circuit. Full review.
Where they actually differ
Connector, and this decides most purchases. The 80-amp Autel is J1772; the 80-amp Grizzl-E Ultimate is NACS. Grizzl-E's J1772 Ultimate versions were unavailable when we last resolved listings, which is why the NACS unit is the Ultimate we feature. If your car has a native NACS port — a Tesla, or a 2025-or-newer Hyundai Ioniq 5 — the Grizzl-E plugs straight in and the Autel needs an adapter. If your car has a J1772 inlet, it is the reverse. See NACS vs J1772 if you are not sure which you have.
Build and weather rating. Grizzl-E's whole proposition is the enclosure: a heavy-duty UL Type 4 indoor/outdoor metal box. Autel publishes an indoor/outdoor rating with a long warranty and a tidier-looking install. If the charger lives on an exposed wall in a hard climate, the Grizzl-E is the more conservative choice — see the outdoor roundup and the cold-weather roundup for how we rank published weather figures.
Cloud dependence. Grizzl-E states that its scheduling and energy stats work with or without an internet connection. Autel leans harder on Wi-Fi and its cloud, which is where the richer app features come from — and which is a real single-point-of-failure consideration if your garage Wi-Fi is marginal. We cover that failure mode in EV charger Wi-Fi connection problems and the case for skipping apps entirely in best dumb EV chargers.
Features per dollar. At the 40-amp tier the Autel is the feature-maximalist pick: app, Bluetooth, OCPP, holster included, 25-foot cable. There is no comparable single-connector Grizzl-E on sale to put against it, so if the shortlist is genuinely "Grizzl-E or Autel" and you have one car and one circuit, the Autel wins by availability as much as by specification.
How they compare on paper
Published manufacturer figures from the live listings, with the live price alongside. Read the connector column before the amperage column.
| Charger | Best for | Published specs (manufacturer) | Price |
|---|
| Autel MaxiCharger 80A (AC Pro) | J1772 cars with a 19.2 kW onboard charger | Up to 80A / 19.2 kW · J1772 · Hardwired · 100A circuit · Wi-Fi + app, 25ft | $908.65 |
| Grizzl-E Ultimate 80A (NACS) | NACS / Tesla cars that can take 19.2 kW | Up to 80A / 19.2 kW · NACS (Tesla-style) · Hardwired · 100A circuit · UL Type 4, works offline | $899.00 |
| Autel MaxiCharger (40A) | Feature-maximalists who want a tidy install | 40A / 9.6kW · J1772 · 25ft cable + holster · Wi-Fi + Bluetooth | $375.99 |
| Grizzl-E Duo Connect (dual 40A) | Two EVs on one circuit | Dual J1772 · Up to 40A shared · Two 25ft cables · NEMA 14-50 plug | $899.99 |
#ad Prices read live from the Amazon Product API as of October 17, 2026, and they move. Specs are the manufacturer's published claims from the live listing — we have not bench-measured them. Where we have no verified price we print none rather than a number that has gone stale.
The question that comes before the brand. An 80-amp charger needs a hardwired 100-amp dedicated circuit, and it only charges faster than a 48-amp unit if your car's onboard charger accepts 19.2 kW. Most do not: the common ceiling is 11.5 kW (48 amps), and some are lower. A retail F-150 Lightning is 48 amps. A Mach-E is 48 amps. An Ioniq 5 is lower still. Check your car first in the 80-amp roundup; if it caps at 48 amps, both 80-amp units on this page are the wrong purchase regardless of which badge you prefer.
Which one should you buy?
You have a NACS-port car and a 100-amp circuit you can spare. Grizzl-E Ultimate. It is the only 80-amp unit here with a native Tesla-style plug, and the metal UL Type 4 enclosure is the most durable thing in this comparison.
You have a J1772 car that genuinely takes 19.2 kW. Autel MaxiCharger AC Pro. That is a short list of vehicles — fleet-configured trucks and a handful of high-end EVs — and if yours is on it, this is the charger.
You have one car and a normal panel. Autel MaxiCharger 40A, and put the difference toward the install. Or step outside both brands: our home charger roundup ranks the whole field and the value picks there are hard to beat. We compare the Autel against its closest rivals directly in Autel MaxiCharger vs Emporia and EVIQO vs Autel.
You have two EVs and one circuit. Grizzl-E Duo Connect. Two connectors sharing 40 amps is a different product from either 40-amp single unit, and it is usually cheaper than running a second circuit — see the best chargers for two EVs and charging two EVs in one household.
Your garage Wi-Fi is bad. Grizzl-E, on its stated ability to schedule without an internet connection. An app-centric charger on a marginal signal is a daily annoyance rather than a feature.
The charger will live outside in a hard winter. Grizzl-E, on the published UL Type 4 enclosure. We rank the whole field by published low-temperature and enclosure figures in the cold-weather roundup.
What neither brand changes
The install. Both 80-amp units are hardwired on a 100-amp circuit; both 40-amp-class units here use a NEMA 14-50 plug and a 50-amp circuit. Under NEC 625.42's 125% continuous-load rule the circuit, not the badge, sets what is possible — our wire size and breaker guide and installation cost guide are the pages to read before you choose either.
