Head to head
Autel MaxiCharger vs Grizzl-E Classic Connect
Identical cable length, identical plug-in speed, both rated for an exposed wall. The differences are all in what happens after you buy.

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.
If you have measured your garage and concluded you need 25 feet of cable, these are two of the four chargers on this site that have it. They are closer than their price difference suggests.

Room to grow, or one job done
The Autel is the more flexible object. Buy the plug-in version now and the same model line exists hardwired at 50 A; it also comes in a NEMA 6-50 version, which matters if your garage has a welder outlet rather than a range outlet. The 6-50 outlet.
The Grizzl-E does one thing: 40 A, plugged in, with a tough case and a long cable. If that is your situation, the flexibility you are not buying is not a loss.
Connector and adapters
The single clearest reason to pick the Grizzl-E is a Tesla or another NACS car in the driveway. It is sold with a NACS cable, so there is no adapter to fit and remove every day. The Autel is J1772 only, which means an adapter for a NACS car.
Which one to buy
| Your situation | Buy |
|---|---|
| A NACS car, no adapter wanted | Grizzl-E Classic Connect |
| A 6-50 outlet in the garage | Autel MaxiCharger |
| You may hardwire later for more speed | Autel MaxiCharger |
| You want the longest published temperature range | Grizzl-E Classic Connect |
| You want a five-year warranty option | Grizzl-E Classic Connect |
The two chargers
Same cable, same plug-in speed. Connector and hardwire headroom decide it.
1. Long reach outdoors
Autel MaxiCharger AC Home
Autel Energy · J1772 · 50 A / 12 kW · 25 ft cable
The 25 ft cable is the longest in this group, and the NEMA 4 case plus a cold-flexible cord make it the easiest unit to live with on an exposed outside wall.
What is good
- 25 ft cable, the longest of the wall units here
- Sold in NEMA 14-50, NEMA 6-50 and hardwired versions
- NEMA Type 4 enclosure rated for rain, snow, hail and sleet
- Wi-Fi and Bluetooth, so it still works if the Wi-Fi drops
What is not
- The 50 A version is hardwired only
- The app has more features than a first-time owner needs
| Maximum output | 50 A / 12 kW hardwired; 40 A / 9.6 kW plug-in |
|---|---|
| Connector | SAE J1772 |
| Cable | 25 ft |
| Enclosure | NEMA Type 4 |
| Certification | Tested to UL standards by CSA |
| Warranty | 3 years |
Skip this if: Skip it if your parking spot is right next to the panel. You are paying for cable you will coil up and never use.

2. Grizzl-E toughness, with an app
Grizzl-E Classic Connect
United Chargers · J1772 · 40 A / 9.6 kW · 25 ft cable
The next-generation Grizzl-E: 40 A on a NEMA 14-50, a 25 ft cable, a UL Type 4 indoor/outdoor rating -- and, unlike the Classic, Wi-Fi and the Grizzl-E Connect app. Sold with a J1772 or NACS cable.
What is good
- 25 ft cable, a foot longer than the Classic Extreme Edition's
- Wi-Fi app with schedules and charging statistics, which the Classic deliberately lacks
- UL/cUL listed, with a published file number
- Rated to run from -22 F to 122 F
What is not
- 40 A ceiling, with no hardwired 48 A version
- Sold with a NEMA 14-50 plug; the Classic's 6-50 option is not among the Connect listings we found
- The app needs 2.4 GHz Wi-Fi where the charger is mounted
| Maximum output | 40 A / 9.6 kW at 240 V (the maker lists 10 kW) |
|---|---|
| Adjustable | 16 A to 40 A |
| Connector | SAE J1772 or NACS, chosen at purchase |
| Cable | 25 ft (7.6 m) |
| Plug | NEMA 14-50 |
| Enclosure rating | UL Type 4, indoor and outdoor |
| Operating temperature | -22 F to 122 F |
| Size | 10.25 x 6.25 x 3.75 in |
| Connectivity | Wi-Fi (2.4 GHz) and the Grizzl-E Connect app |
| Certification | UL/cUL, file E510712 |
| Warranty | 3 years; 5-year warranty sold separately |
Skip this if: Skip it if you wanted a Grizzl-E precisely because it has no app -- the original Classic is still the no-software choice -- or if you want 48 A. The Classic Connect is a 40 A plug-in unit.
