The NEMA 14-50 is a 240-Volt 50-Amp socket. A 240-volt dedicated circuit installed for higher-power devices can be wired as a 14-50 line. High power devices such as electric stoves or welders, are typical applications for level 2 chargers. They are also often used for RV and mobile homes.

The NEMA 14-50 standard socket is US-based and most commonly used for charging electric vehicles. With an appropriate EV charger, it can be used to completely recharge a modern EV battery in fewer than 8 hours.

14-50 NEMA chargers are a type of pluggable device that plugs into an outlet. Some similar devices may be hard-wired to the power grid, thus restricting them from moving.

All of the chargers models under consideration are widely compatible with various non-Tesla electric cars thanks to the J1772 connector. It also charges Tesla cars perfectly when using the included adapter. 

The NEMA 14-50 standard specifies a maximum current of 50A. However, according to the NEC, only 80% of the maximum power is allowed for continuous use. This means that plugging in any charger (even one labeled 50A) will not produce more than 40A for an EV.

Why do customers choose plug-in devices over hardwiring?

1. The charger remains mobile. It can be unplugged at any minute, stowed in the trunk, and used elsewhere.

2. When traveling, you can find access to a 240V outlet, such as for an RV, where the charger plugs in easily.

3. There is an option to plug the charger into your own dryer outlet via an extension cord. This is relevant when you do not want to or cannot have new wiring put in.

4. If your unit becomes defective during the warranty period, you can easily unplug it and send it to the manufacturer for replacement. And you don’t need to call an electrician to remove it.

5. You can use cheaper NEMA extension cords, as opposed to J1772, when someone parks in the driveway needs to charge it.

6. Even if a new outlet has to be installed, the cost won’t exceed the hard installation.

#1 ChargePoint Home Flex 50A — Portability and stability

ChargePoint is one of the most innovative EV chargers on the market. With its sleek design and high-power output, you’ll never go back to a slow charger. The price of the device is above average, but users note the stability in operation. The equipment, in case of power surges, reliably resumes power to the electric car.

This Wi-Fi-enabled charging station offers smart features that can be seen through the ChargePoint app. It can charge at 16 amps to 50 amps, giving drivers the ability to pick the speed that’s right for them and their home’s electrical supply. Although the manufacturer specifies a maximum power of 50A, as with other charging stations it is limited to 80% of the breaker (so you get 40A).

The Charger is UL-Listed and ENERGY STAR-certified. It comes with customer support 24/7 for 3 years. ChargePoint can be installed by any electrician. It can charge at 16A to 40A and comes with a 23-foot charging cable and either a NEMA 14-50.

ChargePoint is fast, reliable, and easy to plug in. This EV charger is compatible with most EVs; no matter the make or model you’re cruising in, you can plug into this for a safe charge that won’t let you down.

You’ll enjoy this charging station because it will power up fast and the cable length is fantastic at 23ft! To save money, it can be programmed to suit your needs with an adjustable timer, so come back to it at night to recharge at the nightly rate. With its incredibly easy NEMA 14-50 installation, ChargePoint Home Flex Cable chargers are perfect for home or portable use.

#2 JuiceBox 32A — Convenient cord storage

Introducing the JuiceBox EV Charger. Get up to 5 times faster charging for your electric vehicle with 32 amperes and 7.7 kWs! Powered by 240 volts, Juicebox is the perfect plug-in installation for any household looking to juice on the go! With efficient use of power and smart grid savings when you schedule your charging times at lower rates, it makes driving affordable without weakening your wallet or depleting the environment with costless emissions. With all that said, users note that setting up Wi-Fi is not the easiest on the device.

The device is capable of balancing the load when another charger is on the grid, protecting the circuit, which is relevant for multiple EVs.

The water-resistant housing allows the device to be installed in a variety of environments. Convenient cable management makes it easy to organize your space, thanks to the moderate flexibility of the 25-foot wire.

#3 MEGEAR 32A— Not smart, but a sufficient solution.

This brand has proven itself since the release of 16A models, which have distinguished themselves by their reliability. The 32A model is no exception in quality.

For wall mounting it has a special lock, which, however, allows you to remove the device and put it in the trunk during a long trip.

A short cable may do the trick if the electric car port is nearby. Otherwise, the user may incur additional costs for an extension cord. 

The charging station has been enhanced with new technology for safer, more dependable protection. Leakage and overvoltage, as well as overcurrent and power-on self-test and fault recovery functions are all provided.

24-Month warranty

Resistant to heat, cold, and dampness

16 Feet of Power Cord – is not enough for some people

No programmable features

#4 MUSTART 32A — Ultra compact model.

This ultra-lightweight portable charger has a compact design. Unlike its predecessors, which also had no WiFi commutation, this model is equipped with a display with current power, temperature sensor, and charging time indication.

If you intend to transport the unit, it will easily fit in a travel bag (included) and will weigh no more than 12 pounds. The cable is an excellent 25 feet long, with medium-flex materials and is quite flexible compared to models in this price range.

For stationary use, it lacks an organized cable storage box around which a long coil can be wound. But it’s worth noting that the plug-in and wire won’t be lying around on the floor; 2 wall clips are included, one for the handle and one for the cable. There are also special hinges for affixing the control box, but they do not fix the device too firmly.

A sufficiently high dust and moisture resistance rating of IP67 will not interrupt charging in rainy weather. User feedback on the quality is not bad, but the manufacturer could give a warranty of more than 1 year.

#5 LEFANEV 32A — Sturdy box.

This model already resembles the usual stationary box, although it can be loaded into the trunk. Compared to other models, this one has a large display with the current charging power readings. Bright light indication will not allow you to be confused when the car is charged and clearly indicates the other statuses.

When the multi electric gadget is switched on, a power leveler at the station balances it to keep the station running at a constant current without causing sparks or other safety concerns.

If convenient portability is important to you, there is a metal wall bracket mounted on the wall with a kit for installation. The special hook included in the kit comes in handy for storing the cable on the wall.

The lack of communication with Wi-Fi has not deprived the sympathy from users for this device. Reliability and high stability is confirmed by the sturdy case.

The declared maximum power of 7.7 kWh of the device is assured.


Durable and long-lasting build construction.

Is there a power limit on outlets for chargers?

The NEC requires that the maximum power of the devices connected through the socket must not exceed 40A. With NEMA 14-50 outlets, the power is limited to 80%.

What is the disadvantage of plug-in EV charger versus hardwiring?

The socket is limited to 40A power. With a hardwired connection, it is theoretically possible to install higher wattage chargers. However, not all electric car models support higher amps.

At what maximum power can I charge an EV or Tesla at home?

Most EVs have a limit of 48 amp when charging with alternating current, which is exactly what is used in domestic power grids. For direct current, the limits are much higher, which allows you to charge the car several times faster. You can find out the limits for your specific vehicle in the vehicle data sheet or by using the calculator we have developed.

Do I have to attach the charger to the wall in any way?

To install the EVSE, make sure it is mounted on a wall and does not require you to plug it into an outlet. Outlets are not designed to support the weight of an EVSE.

Can I plug the charger into the outlet from the dryer?

Technically you can do it. There are also special certified extension cords. Regardless, a dedicated NEMA outlet is highly recommended. Have an electrician verify all the wiring is in compliance with local code requirements and then connect to the outlet.

Can an extension cord with a NEMA 14-50 charger be too long?

J1772 extension cables are frequently at 40 feet. If you want to wire a NEMA 14-50 electrical outlet for a 40-amp circuit, you’ll only come across 50-foot sections. If you are wondering what is the best type of extension cord to choose, then take a look at the review of the best extenders with a comparison.

Our pick

Our choice is driven by the factor of reliability combined with the highest performance for the Nema 14-50 standard. The ChargePoint Home Flex 40A is in the highest priced, but it has proven certifications and the highest customer satisfaction rating. This manufacturer has established itself not only among home devices but above all among equipment for public networks.
