The best outlet for Level 1 EV charging

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 verdict: if the garage is unheated -- which is most garages -- buy the Leviton 5362-SG. It is the only receptacle here published to -40 C and up to 75 C, it uses a brass strap rather than plated steel, it can be back-wired for a tidier joint, and it carries tamper-resistant shutters and a 10-year warranty. If the outlet is indoors and warm and you want the cheap-but-correct answer, the CR020 is commercial specification grade with brass line contacts for the price of a coffee. If an inspector or the code requires ground-fault protection at the receptacle, the GFTR2 is the self-test, Class A device to use -- and then do not also put a GFCI breaker behind it.

Why a builder-grade outlet is the weak link

This site has made the same argument about the NEMA 14-50 receptacle, and it is more true at 120 V, not less. A charging cord holds its plug in one receptacle under load for most of the night. Cheap receptacles use thin plated contacts that relax over time; a relaxed contact is a resistive contact, and a resistive contact under a continuous load gets warm. Warm is how a receptacle dies, and occasionally how something worse happens.

The useful thing about specification-grade parts is that the maker publishes the test. Leviton states a temperature rise of no more than 30 C after 100 cycles at 150% of rated current for the commercial part, and after 250 cycles at 200% for the industrial ones. You do not have to take a view on construction quality; you can read the number.

Twenty amps, and why that matters here

All four of these are 20 A, NEMA 5-20R devices. A Level 1 cord draws about 12 A, so a 15 A receptacle is not overloaded by it -- but 12 A continuous is 80% of a 15 A device's rating, which is exactly the region where the cheap parts age. A 20 A specification-grade device run at 12 A is working at 60% of rating with brass contacts. That is the margin you are buying.

Note what this does not change: the circuit. If the garage outlet is one of six on a single 15 A branch shared with the freezer and the door opener, the receptacle is not your problem. Does an EV charger need its own circuit is that conversation, and how many amps do you need is the one after it.

The GFCI question, without hand-waving

Ground-fault protection in garages is a live code topic and the requirement depends on your edition and your local adoption, which is why this page does not tell you whether you need it. What it can tell you is how to do it once you know. Use one device: either a GFCI receptacle at the outlet or a GFCI breaker at the panel. Putting both on the same circuit is the classic cause of a charge that stops in the night for no visible reason -- GFCI nuisance tripping is the full version, and it is the single most common charging complaint we write about.

If you do use a receptacle, use a self-test one. The GFTR2 checks its own trip mechanism rather than relying on somebody pressing a button once a month, publishes a Class A 5 mA plus or minus 1 mA trip level, and carries a 10 kA short-circuit current rating and a V-0 flammability rating. The trade is the warranty: two years, against ten on the plain receptacles.

The picks

1. An unheated garage or a cold outbuilding

Leviton 5362-SG 20 A extra heavy-duty industrial tamper-resistant receptacle

Leviton · NEMA 5-20 · 20 A / 2.4 kW

The one to put in an unheated garage. Extra heavy-duty industrial grade, a brass strap, back or side wiring, tamper-resistant shutters as standard, and the widest published temperature range in this group.

What is good

• +Published to -40 C and up to 75 C, the widest range in this group
• +Brass strap rather than plated steel, which is the mark of the top grade
• +Back or side wiring, so an electrician can make a tidier, lower-resistance joint
• +Tamper-resistant shutters included rather than a separate part number
• +250-cycle overload test at 200% of rating, published

What is not

• −Roughly ten times the price of the plain commercial part
• −Tamper-resistant shutters are stiff at first and some people dislike them
• −Still a 120 V, 20 A outlet -- it does not change Level 1 charging speed
• −Leviton publishes a tamper-resistant notice worth reading before you fit it in a garage

2. A garage 120 V outlet that needs GFCI protection

Leviton GFTR2 20 A SmartlockPro self-test hospital grade GFCI receptacle

Leviton · NEMA 5-20 · 20 A / 2.4 kW

The GFCI version, and the one the code conversation is usually about: a Class A 5 mA self-test device rated 20 A with a 10 kA short-circuit rating, tamper-resistant, with the wallplate in the box.

What is good

• +Class A 5 mA trip level published, which is the figure the code language is written around
• +Self-test, so the device checks its own trip mechanism rather than relying on you pressing the button
• +V-0 flammability and a 10 kA short-circuit rating -- the toughest ratings in this group
• +Tamper-resistant and hospital grade, with the wallplate included
• +Back and side wiring, solid or stranded

What is not

• −2-year warranty, against 10 years on the non-GFCI parts
• −Do not stack it behind a GFCI breaker; pick one device or the other
• −Narrower published range than the 5362-SG (-35 C against -40 C)
• −Hospital grade is a cost a garage may not need; the plain GFCI version is cheaper

Published specifications for the Leviton GFTR2 20 A SmartlockPro self-test hospital grade GFCI receptacle

3. A garage or utility outlet where the face plate matters

Leviton Decora Plus 16342 20 A spec grade duplex receptacle

Leviton · NEMA 5-20 · 20 A / 2.4 kW

The same electrical job as the CR020 in a Decora face, with a thermoplastic nylon body and face, a tougher published overload test and the same 10-year warranty. Buy it when the outlet is somewhere you look at.

What is good

• +Published 250-cycle overload test at 200% of rating -- a tougher stated test than the plain commercial part
• +Thermoplastic nylon body and face rather than unspecified plastic
• +Decora opening matches the rest of a modern plate run
• +10-year warranty
• +1 HP motor rating, a useful proxy for inrush tolerance in a garage

What is not

• −Costs more than the CR020 for the same amperage and voltage
• −Needs a Decora wallplate, a second purchase if you do not have one
• −No tamper resistance
• −Side wire only

Published specifications for the Leviton Decora Plus 16342 20 A spec grade duplex receptacle

Rating	20 A, 125 V AC, NEMA 5-20R

4. Replacing a worn garage outlet used for Level 1 charging

Leviton CR020 20 A commercial spec grade duplex receptacle

Leviton · NEMA 5-20 · 20 A / 2.4 kW

The cheapest step out of builder-grade for a 120 V garage outlet: a commercial specification grade 20 A receptacle with brass line contacts, a self-grounding strap and a 10-year warranty, for the price of a sandwich.

What is good

• +Brass line contacts and a published temperature-rise test, which builder-grade parts do not state
• +Self-grounding strap, so the ground does not depend on a box screw
• +10-year warranty on a part that costs a few dollars
• +Specified terminal torque, which is the number a careful electrician will actually use
• +The right grade for an outlet that holds a plug under load for eight hours a night

What is not

• −No tamper resistance at this grade
• −Side wire only -- no back-wire clamp
• −It is still a 20 A, 120 V outlet: it does not make Level 1 charging faster
• −Changing a receptacle is electrician work for most people, which is a call-out charge on a $4 part

Published specifications for the Leviton CR020 20 A commercial spec grade duplex receptacle

Rating	20 A, 125 V AC, NEMA 5-20R
Grade	Commercial Specification Grade
Grounding	Self-grounding
Line contacts	Brass, 0.031 in thick
Ground clips	Brass
Strap	Zinc-plated steel
Termination	Side wire; 14-10 AWG; 14-18 in-lb terminal torque

Flammability	Rated V-2 per UL94
Standards	UL 498, Fed Spec W-C-595G, CSA C22.2 No. 42
Warranty	10 years limited

Skip this if: Skip it if the outlet shares a 15 A circuit with half the garage -- the receptacle is not the problem then, the circuit is. Skip it too if you want tamper resistance; the 5362-SG is the version with it.

5. Travel and rentals

Lectron portable Level 2 charger

Lectron · J1772 · 32 A / 7.7 kW · 21 ft cable

A plug-in portable that runs at Level 2 speed from a NEMA 14-50 and drops to a standard wall outlet with the included adapter. The travel unit, not the garage unit.

What is good

• +Level 2 speed from a NEMA 14-50 without an installed charger
• +Falls back to a standard household outlet with the adapter
• +Small enough to keep in the trunk

What is not

• −32 A ceiling, meaningfully slower than a 48 A wall unit
• −Not weather-rated for permanent outdoor mounting
• −Repeated plugging and unplugging wears a NEMA 14-50 receptacle faster than a hardwired unit

Published specifications for the Lectron portable Level 2 charger

Maximum output	32 A / 7.7 kW at 240 V
Connector	SAE J1772
Plug	NEMA 14-50, with an adapter for a standard outlet
Use	Portable. Lives in the car, not on the wall

Skip this if: Skip it if this is your only charger and you have a garage. A wall unit is faster and does not live in your trunk.

What Level 1 actually gets you

It is worth closing on the thing the outlet is for. The Department of Energy puts Level 1 at roughly 5 miles of range per hour against about 25 for Level 2. Over a 10-hour night that is around 50 miles, which is more than the average US daily drive -- so for a second car, a plug-in hybrid or a short commute, 120 V is a complete answer rather than a stopgap. Do you need a Level 2 charger walks through where the line is, and the best Level 1 EV charger covers the cord itself.

The fifth pick below is the cord, and it is here because it is the one that works both ways: the Lectron portable runs at Level 2 speed from a 240 V outlet and drops to a standard wall outlet with the adapter in the box. If you are specifying a good 120 V receptacle today and may add a 240 V circuit later, that is the cord that follows you across. The four receptacles above it are the part that stays in the wall.
