The number 40 does a lot of work in this keyword. A 40 amp Level 2 charger on a 240 volt supply works out to 9.6 kilowatts, which is the figure printed in many of the listings below, and it sits right at the point where a charger is meaningfully faster than a basic 32 amp unit but still plugs into a common NEMA 14-50 outlet. For owners with a garage, a dryer-style outlet and a vehicle that can accept that much current, it is a popular middle ground between slow wall-outlet charging and a heavy hardwired installation.
This guide is for drivers shopping for a portable or wall-mounted J1772 charger at 40 amps, comparing cable length, plug type, certification claims and smart features. Every comparison comes from the product titles only. Whether the vehicle can actually draw 40 amps, whether the existing circuit is sized for it and whether the connector fits the car must all be confirmed on the listing and in the vehicle owner’s manual before purchase in 2026. Electrical installation or outlet work should be done by a licensed electrician following local code.

How to Choose
Circuit capacity comes before the charger
A 40 amp charger is generally paired with a 50 amp circuit, because continuous loads are commonly limited to 80 percent of the breaker rating. That means the outlet, wiring and breaker must be sized for it, and the chosen outlet type must match the plug. A NEMA 14-50 receptacle is common in garages and RV hookups, but it needs to be in good condition and properly installed. Never exceed the rated load on the listing, and use a licensed electrician to verify or install the circuit.
Check the vehicle and the connector
J1772 is the common connector for many non-Tesla vehicles in North America. Some titles specifically mention J1772 and others mention Tesla compatibility, so confirm the connector or any adapter needed for the specific vehicle. Not every car can accept 9.6 kW, and the vehicle’s onboard charger sets the actual speed. Check the owner’s manual for the maximum AC charging rate before paying for a higher-amp unit, and look for adjustable current so the charger can be dialed down if the circuit requires it.
Portable versus wall-mounted
Portable units plug into a NEMA 14-50 outlet and travel with the car, which is handy for visiting family or a rented garage. Wall-mounted units stay put, keep the cable off the floor and often have a sturdier case. Cable length matters: 25 feet reaches most driveways, while 16 feet suits a car parked near the outlet. Cable weight, flexibility and a holster or hook for storage reduce wear over time, and a coiled cord on a garage floor is a trip hazard.
Certification and smart features
Look for a listing mark such as ETL or UL, but read the listing since titles can overstate. Certification is a manufacturer claim to verify, not a guarantee of safe installation. Smart features such as WiFi apps, RFID access and delay timers are nice for off-peak charging, but they depend on a 2.4GHz network and an app. Ignore marketing about fast charging unless a kilowatt figure supports it, and be careful with budget units that skip clear certification details. Weather-rated cases matter for outdoor use.
The 7 Best Options
BETUMODA Level 2 EV Charger, 40 Amp
BETUMODA is a portable J1772 unit with a 240V, 9.6kW rating, a 25 foot cable, an LED display and a NEMA 14-50 plug. It is aimed at home garage use with a plug-in outlet. For drivers who like a quick visual check before walking away from the car, an on-unit display is a practical touch, and the plug-in format means the charger can move with the vehicle if the household changes.
- Strength: LED display shows charging status at a glance
- Strength: 25 foot cable gives flexibility in how the car is parked
Trade-off: the visible title does not list a certification mark. Skip it if a clearly stated ETL or UL listing is required before purchase. Confirm the plug and cord details on the listing and make sure the outlet matches. A worn or loose receptacle is a common cause of overheating complaints with high-current plug-in chargers, so inspect it first.
ELEGRP Level 2 EV Charger 40Amp
ELEGRP is a portable J1772 charger with a NEMA 14-50 plug, ETL certification claim and a 25 foot extension cable. It is a straightforward option for buyers who want a certified portable unit. The long cable is the practical feature, since it removes the need for any separate extension and keeps the connection points to a minimum.
- Strength: ETL certification is listed in the title
- Strength: 25 foot cable adds reach
Trade-off: no display or smart features are mentioned in the visible title. Skip it if app control or a screen readout is wanted. Verify certification details on the listing before relying on the claim. Anyone who wants scheduling should look at models that mention a timer, since this title does not.
SEGUMA Level 2 EV Charger, 40A
SEGUMA lists ETL certification for J1772 battery and plug-in hybrid vehicles, a 25 foot cable, a NEMA 14-50 plug, adjustable current and a timing delay. It suits buyers who want scheduling in a portable unit. Adjustable current is especially useful where a garage circuit is shared or where a car cannot accept the full amperage, since the output can be lowered rather than replaced.
- Strength: adjustable current helps match the circuit or vehicle limit
- Strength: timing delay supports off-peak charging
Trade-off: no WiFi or app control is stated. Skip it if remote monitoring matters. Check the listing for how the delay and current settings are changed, and for the connector and cable details the title does not spell out.
EVDANCE Level 2 EV Charger, 40Amp 240V
EVDANCE lists 40 amps, 240V and 9.6KW, a NEMA 14-50P plug, a 25 foot cable and adjustable current with timing delay. A separate EVDANCE listing mentions Tesla, so connector compatibility must be confirmed. The delay timer is helpful for drivers on time-of-use electricity plans who want charging to start after a set hour instead of the moment the car is plugged in.
- Strength: adjustable current and delay timer in a portable unit
- Strength: 9.6KW rating stated clearly
Trade-off: certification details are not visible in the title. Skip it if a listed mark is required before buying. Check which connector the chosen version ships with, and whether a Tesla owner would need an adapter for the J1772 version.
Lectron Level 2 EV Charger, 40 Amp
Lectron offers a standard version and a WiFi version, both with 40A, 240V, a NEMA 14-50 plug and a 16 foot extension cord with a J1772 cable. The standard listing mentions ETL certification. The shorter cord keeps the cable tidy in a one-car garage where the outlet sits near the parking spot, and the WiFi version suits owners who like app visibility.
- Strength: WiFi version adds app-based features
- Strength: ETL certification is mentioned on the standard model
Trade-off: 16 feet is shorter than the 25 foot cables elsewhere. Skip it if the car parks far from the outlet. Confirm which model includes which features, since the two listings differ in connectivity and may differ in other details.
Grizzl-E Classic 40A Level 2 Charger
Grizzl-E is a wall-mounted station with a metal case for indoor or outdoor use and a 40A, 9.6 kW rating. The titles list a UL certification claim and one version adds smart connectivity. A sealed metal enclosure appeals to owners who plan to mount the charger on a garage wall or an outdoor post, and a hardwired or plug-in installation depends on the version and local code.
- Strength: metal case suits garages and outdoor walls
- Strength: UL certification is mentioned in the title
Trade-off: it is a fixed station, so installation needs a qualified electrician and the unit stays in place. Skip it if a portable unit is needed. Confirm whether the version includes smart features and what wiring it needs. Installation by a qualified electrician is the usual path for a fixed station.
Smart Level 2 EV Charger, 40A NEMA 14-50P
This unbranded unit lists a 25 foot cable, a J1772 wall charger format, 9.6kW, ETL and UL certification, a 2.4GHz WiFi smart app, RFID and button control. It targets buyers who want plug-and-play control. Several ways to start and stop a session, including a physical button, make it flexible for households with more than one driver.
- Strength: app, RFID and button controls provide several ways to operate it
- Strength: both ETL and UL listings are claimed
Trade-off: no brand is visible, so support and warranty details need checking. Skip it if the home network is 5GHz only, since the title names 2.4GHz WiFi. Verify the certification claims on the listing.
Which One Fits Your Situation
A driveway parking spot far from the garage outlet
The 25 foot cables on the BETUMODA, ELEGRP, SEGUMA and EVDANCE give the most reach.
Charging on a utility off-peak schedule
The SEGUMA and EVDANCE list timing delay, while the smart wall charger adds an app.
An outdoor wall installation
The Grizzl-E, with its metal indoor and outdoor case, is the fixed-station choice, installed by an electrician.
A car parked next to the outlet
The 16 foot Lectron is enough when the outlet is close, and the WiFi version adds monitoring.
