Autel MaxiCharger 50A Review: The 25 Foot Cable Pick

Fifty amps on paper, a NEMA 4X enclosure, and the circuit arithmetic that decides where you actually set it.

Specifications

Specifications above come from Autel's published specifications. Treat pricing as approximate, since Amazon pricing moves.

What it does well

• Twenty five feet of cable is at the top of the range and quietly solves the most common installation problem, which is reaching the charge port.
• A NEMA 4X enclosure is a serious outdoor rating, better than the 3R that many competitors specify.
• Ethernet as well as WiFi, which is unusual and genuinely useful in a detached garage with a wired run and no wireless coverage.
• CSA testing to UL standards means it qualifies for the rebate programmes that require an NRTL listing.

Where it falls short

• Running it at a true 50 amps requires a 70 amp circuit under the 125 percent continuous load rule, which is why most installations set it to 48 amps on a 60 amp breaker. Read the headline number with that in mind.
• The app is capable rather than simple, and owners new to connected chargers describe a learning curve.
• Autel is an automotive diagnostics company rather than an electrical manufacturer, so the long term support story is less established than Leviton's or ChargePoint's.
• Hardwired installation, so there is no taking it with you when you move.

What owners report

Published owner reports are consistently good on the hardware: cable length, build and weather resistance all draw praise, and reports from cold and wet climates are notably positive given the NEMA 4X rating.

The app is where reports vary. Owners who wanted a simple schedule describe more options than they needed; owners who wanted control describe it favourably. Reports of firmware updates changing behaviour appear occasionally, which is true of every connected charger and is the price of a device that improves over time.

Who it suits

• Installations where the car parks a long way from the only viable mounting point.
• Outdoor installs where a NEMA 4X enclosure is worth having.
• Detached garages with an Ethernet run and no usable WiFi.

Who should skip it

• Anyone who wants the simplest possible app experience.
• Buyers who want a plug-in unit they can take with them.
• Owners of cars capped at 7.7 kW, who can spend considerably less.

Common questions

Does a 50 amp charger need a 70 amp breaker?

At a true 50 amp continuous output, yes: the continuous load rule sizes the circuit at 125 percent, which is 62.5 amps, and the next standard breaker is 70. That is why most installations configure this charger to 48 amps on a 60 amp circuit, which is a far more common household circuit. Our breaker size calculator lays out each option.

Is 25 feet of cable too long?

Only for cable management. A longer cable is heavier and needs somewhere sensible to hang, and a holster or hook is worth buying at the same time. What it buys you is the freedom to park either way round, which owners of shorter cabled chargers routinely wish they had.

Is Autel a trustworthy brand for a charger?

Autel has been in automotive diagnostics since 2004 and the charger is tested to UL safety standards by CSA, which is a Nationally Recognized Testing Laboratory. That listing is what matters for safety and for rebate eligibility. The open question is long term support, where mainstream electrical brands have a longer record.

Autel or ChargePoint Home Flex?

Close call at similar money. Autel gives a longer cable and a NEMA 4X enclosure; ChargePoint gives an app tied to a large public network. If you charge away from home often, ChargePoint's single app is worth something. If not, take the cable.

Can I install it on a NEMA 14-50 outlet?

This version is hardwired. Plug-in versions of the MaxiCharger exist and are limited to 40 amps, because a NEMA 14-50 receptacle supports 40 amps continuously. Our hardwired versus plug-in comparison covers which route suits which household.
