6-50 picks

The best EV chargers for a NEMA 6-50 outlet

A NEMA 6-50 is a 50-amp, 250-volt outlet with no neutral, and many garages already have one. Two wall units come with a 6-50 plug, and one portable reaches it with an adapter.

For a Level 2 charger, a 6-50 does the same job as the more common 14-50: both sit on a 50 A circuit and both allow 40 A of continuous charging. The catch is the plug. Most plug-in chargers ship with a 14-50, so the useful question is which ones come with a 6-50 -- or reach one properly. 6-50 vs 14-50.

What a 6-50 gives you

The arithmetic

NEMA 6-50 circuit: 50 A

Continuous limit: 50 x 0.8 = 40 A

40 A x 240 V = 9,600 W = 9.6 kW

At 3.5 mi/kWh: about 34 miles of range per hour

Match the plug to the outlet

  • Grizzl-E Classic, 6-50 version -- a cast-aluminum, no-app wall unit that plugs straight in. Grizzl-E review.
  • Autel MaxiCharger, 6-50 version -- 25 ft of cable and an app; the 50 A version of the same charger is hardwired only. Autel review.
  • J+ Booster 2 with J+'s 6-50 adapter -- a portable that also runs from a 14-50 and a standard outlet with the adapters in the box. J+ Booster 2 review.

The receptacle matters too

A plug-in charger is only as good as the receptacle behind it, and an EV asks far more of it than a welder or a range ever did. The best 6-50 outlets covers the industrial-grade receptacles to ask your electrician for.

The 6-50 chargers in detail

Two wall units with a 6-50 plug and a portable with a 6-50 adapter, each with the case against it.

1. Harsh weather and no app

Grizzl-E Classic

United Chargers · J1772 · 40 A / 9.6 kW · 24 ft cable

A cast-aluminum box with no app, no account and no firmware to update. If you want a charger that behaves like an appliance, this is the one.

What is good

  • Cast aluminum NEMA 4 / IP67 enclosure, built for outdoor mounting
  • No app, no account, no network dependency
  • Amperage is set with physical switches, not software
  • Protections for over-current, over-voltage, ground fault and over-temperature

What is not

  • 40 A ceiling, slower than the 48 A units if your panel can take more
  • No scheduling, so off-peak charging has to be set in the car
  • The cold-flexible 24 ft cable is only on the Extreme Edition
Published specifications for the Grizzl-E Classic
Maximum output40 A / 9.6 kW at 240 V
Adjustable16, 24, 32 or 40 A
ConnectorSAE J1772
Cable24 ft on the Extreme Edition
EnclosureCast aluminum, NEMA 4 / IP67
CertificationUL certified
Warranty3 years

Skip this if: Skip it if you want scheduled charging or energy tracking in an app. The Classic deliberately has neither.

2. 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
Published specifications for the Autel MaxiCharger AC Home
Maximum output50 A / 12 kW hardwired; 40 A / 9.6 kW plug-in
ConnectorSAE J1772
Cable25 ft
EnclosureNEMA Type 4
CertificationTested to UL standards by CSA
Warranty3 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.

3. The best portable overall

J+ Booster 2

J+ Americas · J1772 · 40 A / 9.6 kW · 25 ft cable

A 40 A portable in a military-grade aluminum body, ETL certified to UL standards and IP67 rated, weighing 2.2 lb without cables. The portable that behaves like a wall unit.

What is good

  • 40 A, matching many wall-mounted units
  • Eight amperage settings from 6 A to 40 A, so it fits almost any outlet
  • Adapters for a wide range of outlets, including NEMA TT-30 for campgrounds
  • IP67 and drive-over resistant, which portables usually are not
  • 2.2 lb without cables, so it genuinely travels

What is not

  • Costs more than most portables, and more than some wall units
  • Every extra outlet adapter is a separate purchase
  • Still a portable, so it is not rated for permanent outdoor mounting
Published specifications for the J+ Booster 2
Maximum output40 A / 9.6 kW at 240 V
Adjustable6, 8, 12, 16, 20, 24, 32 or 40 A
Power range1.4 kW to 9.6 kW
ConnectorSAE J1772
Cable21 ft or 25 ft, depending on version
Adapters includedNEMA 14-50 and 5-15
Further adapters available5-20, 6-15, 6-20, 6-50, TT-30
Weight2.2 lb without cables; 7 lb with cables and adapters
BodyMilitary-grade aluminum, drive-over resistant to 6,600 lb wheel loads
RatingIP67 waterproof and dustproof
CertificationETL certified to UL standards

Skip this if: Skip it if you only ever charge in one place. A hardwired wall unit is cheaper for a fixed installation.

FAQ

Questions people actually ask

Can I charge an EV from a NEMA 6-50 outlet?
Yes, with a charger sold with a 6-50 plug, such as the Grizzl-E Classic or Autel MaxiCharger 6-50 versions, or a portable with its manufacturer's 6-50 adapter. Expect up to 40 A.
Is a 6-50 as fast as a 14-50 for EV charging?
Yes. Both sit on a 50 A circuit and both allow up to 40 A continuous, which is 9.6 kW.
Can I use a 14-50 charger on a 6-50 outlet with an adapter?
Only with an adapter made or approved by the charger's manufacturer. For a wall unit, buying the 6-50 version is the better answer.
