Autel MaxiCharger AC Home

Twenty-five feet of cold-flexible cable in a NEMA Type 4 case. If your car parks a long way from where the charger has to go, this is the shortlist of one.

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 short version: the MaxiCharger's 25-foot cable is the longest of the wall units we cover, and cable length is the one spec you cannot fix after installation. If your measurement comes out awkward, that alone can decide it.

Why two extra feet matter more than they sound

Cable length is not measured in a straight line. It runs down the wall, across the floor, around whatever is in the way, and back up to a charge port that might be on the opposite corner of the car from where you assumed. By the time you have added slack so the cable is not under tension, a 23-foot cable and a 25-foot cable can be the difference between comfortable and unusable.

Do the measurement described in cable length first. If you have plenty of margin, buy on other criteria. If you do not, buy the longest cable available and stop optimizing.

Versions and amperage

The MaxiCharger is sold in several configurations, and the amperage depends on which one you buy: the plug-in NEMA 14-50 and NEMA 6-50 versions run at 40 amps, while the 50-amp version is hardwired. This is the same code constraint every manufacturer works under -- a 50-amp receptacle circuit cannot carry a 50-amp continuous load, so plug-in units cap lower.

What each version delivers

Plug-in, 40 A: 40 x 240 = 9.6 kW, about 34 miles per hour at 3.5 mi/kWh

Hardwired, 50 A: 50 x 240 = 12.0 kW, about 42 miles per hour

The difference over a 10-hour night is roughly 80 miles -- real, and irrelevant for most drivers.

Wi-Fi and Bluetooth, which is the right combination

The MaxiCharger publishes both Wi-Fi and Bluetooth. That matters more than it sounds: a charger with Wi-Fi alone becomes locally uncontrollable if your network is down, whereas Bluetooth keeps the phone-to-charger link working regardless. It is a small design decision that removes a real failure mode.

Who should not buy it

  • Your parking spot is right next to the panel. You are paying for cable you will coil and never use.
  • You want 50 A with a plug. The 50-amp version is hardwired only.
  • You want a unit with no app at all. Buy the Grizzl-E.
  • You want the simplest possible app. The MaxiCharger's has more in it than a first-time owner needs.
