There’s no one size fits all answer. We’ll help you figure out what’s right for you.
There are a lot of factors to consider when shopping for home EV charging equipment for your electric vehicle. You certainly want to make sure you’re buying a unit from a reputable company, that the unit is safety certified, has a good warranty, and is built to last many years.
However, one of the most important considerations is: How powerful of a charging station do you need? Most battery-electric vehicles (BEVs) available today can accept between 40 to 48-amps while charging from a level 2, 240-volt source. However, there are charging stations available today that can deliver more power, and some that can deliver far less, so deciding how many amps you need for your EV charger might seem a little confusing.
There are four main questions you should consider before purchasing your home EV charging equipment.
How much power can your EV accept?
Electric vehicles are limited to accepting a certain amount of electricity which will be listed in either amperage (amps) or kilowatt (kW). All EVs have onboard chargers, which convert the electricity they receive in the form of alternating current (AC) to direct current (DC) which is how it is stored in the vehicle’s battery.
The power of the onboard charger dictates how much AC power the vehicle can accept. Some EVs have more powerful onboard chargers than others, and they range in power from 16-amps (3.7 kW) up to 80-amps (19.2kW). Therefore, the first thing you need to consider is how much power can your EV accept.
How many miles do you usually drive?
Most Americans drive about 40 miles per day. With home EV charging, you only need to replenish the miles you drove that day because you can plug in every night when you arrive home. Therefore, it’s a good idea to know what your daily and weekly driving needs are, because you can probably get by just fine with a home charger that delivers much less power than your EV is capable of accepting.
If you do use a lower-powered home charger and occasionally need more range for a long trip, you can access public DC fast chargers to rapidly charge up for the long drive.
How much power is available at your home?
Your home has a limited supply of electricity, and you may not have enough available power to install a high-powered dedicated circuit for the EV charger without an expensive service upgrade.
You should always have an electrician perform a load calculation of your service before purchasing your EV, so you know if you can install a home charger, and if so, what is the maximum amperage it can deliver.
What is your EV charger budget?
Besides the cost of any possible electric service upgrades, you may need to install the dedicated EV charging circuit, you also need to consider the cost of the charger. Electric vehicle charging equipment can cost as little as 200, and it can also cost up to 2,000, depending on how powerful the unit is and what features it offers.
You should decide what you can and are willing to pay for the charger and installation before searching for a charger. Talk to your electrician about the difference in cost to install the charger based on how many amps it will deliver.
Lower-powered chargers should cost less to install because the thinner wire as well as the less-powerful circuit breaker will cost less than what is required for higher-powered chargers.

Eye on the future
While you may be just getting your first electric vehicle, it surely won’t be your last. The entire industry is in the early years of transitioning to EVs while internal combustion is being phased out. Therefore, it makes sense to consider down the road when you may have two EVs in the garage.
If you have the budget to install a high-powered circuit for charging now, it’s probably the right decision, even if your current EV cannot accept all the power the circuit can deliver. In a few years, you may need to charge two EVs at once, and the single high-powered circuit can power two EV chargers, and ultimately save you the expense of installing a second, lower-powered circuit.

Best 11Kw Home EV Chargers
We selected 4 EV Chargers that are capable of outputting this kind of power and we review everything about them from compatibility, features, performance and cable length.
Let’s have a look at each product in particular.
ChargePoint Home Flex – Level 2 EV Charging Station (16-50 Amp)
The ChargePoint Home Flex is the first 11 kW EV Charger that we’ll be reviewing and one of our favorite. Actually, technically it can go up to 12 kW because this is a 50 Amp charger.
It can work at any amperage between 16 to 50 Amps as long as it is plugged into a NEMA 14-50 or a NEMA 6-50 outlet running at 240V. The other end of the cable that plugs into the electric vehicle’s charging port is a J1772 connector, something which is universal to all EVs in North America.
So let’s understand how these performance figures can translate into actual charging times: The Tesla Model Y will take between 6 to 7 hours to charge, the Long Range Model 3 should take about 6 and the Mustang Mach E should also come close to 6 hours.
This wall mounted EV charging station comes with a cable that is 23 feet long (Approximately 7 meters) and is connected to the charger in a way that it can’t be removed, that is because it’s a tethered charger but then again none that we’ve found for sale in the USA allow you to disconnect it.
Then there is the smartphone app and here, ChargePoint had an interesting approach: You use the same ChargePoint app for your Home Flex that you use to find a public charger, making the app a full charging solution. It lets you schedule charging times in order to take full advantage of off-peak electricity and it can set reminders so that you don’t forget to plug in your car every night. It also keeps track of all your charging session and can basically tell you how much you’re spending on charging your electric car every month.
The outer case is NEMA 3R rated which is the equivalent of IP14, so you can’t really place it outdoors in the open. This is probably one of its more weaker points.
Wallbox Pulsar Plus – Level 2 EV Charging Station (48 Amp, 11 kW)
The Wallbox Pulsar Plus is the second 11kW EV Charger we’ll be studying here. It has a charging power of 11.5 kW and this one doesn’t plug into any NEMA outlet, it has to be hardwired to a 240V circuit.
It comes with a charging cable that measures 25 feet (7.6 meters) and the holster is built into the charger, it’s really easy to holster it plus it has that cool backlight that not only provides you with instant info on what the charger is doing depending on the color, but is also really easy to find in the dark.
Like the Home Flex, it is also a Smart charger with Wi-Fi and Bluetooth connection and a smartphone app. The Wallbox app as its name is, can help you remotely start or stop charging your car remotely, schedule specifing charging times for your car every day and the fun thing is you can do some of these just by using your voice since it is integrated with Amazon Alexa and Google Assistant.
From the point of view of connectivity and smartphone app, we would conclude that there is no major difference between this electric car charging station and the Home Flex, since both will provide more or less the same info and remote commands.
This charger’s outer case is clearly tougher and sturdier because it is IP54 rated so it will be able to take a lot more water, dirt and the dust than the ChargePoint. Every Wallbox comes with a 3-Year warranty when you buy it.
Emporia Smart – Level 2 EV Charging Station (48 Amp)
The Emporia Smart 48A is our third 11 kW EV Charger that we’ll be looking at. This is an 11.5 kW EV Charger that can plug either into a NEMA 14-50 socket or can be hardwired to a 240V Circuit. A cable that is 24 feet long (7.3 meters) stretches out and it is permanently connected to the charger.
In terms of connectivity and the smartphone app, Emporia have had a slightly different approach. There is Wi-Fi connectivity and you can connect to the charger using the Emporia app, so far so good. But you’ll notice that the app is more focused towards monitoring energy consumption and helping you save money. For example, beyond the usual charge scheduling feature you can also set it to only charge when the solar panels are producing energy, so it is not using any amount of energy from the grid. This is something that is unique.
On this fast charger you’ll find the 4 LEDs that tell if you it is powered on, if it’s charging your EV or if there is a fault. The unit is IP66 rated, so it can easily sit outdoors because it is waterproof and dustproof. Plus the unit comes backed up by a 3-year warranty.
PRIMECOM – Level 2 EV Charging Station (50 Amp, 30 feet)
The PRIMECOM charging station is our last 11 kW EV charger that we’ll be looking at. Like the Home Flex, it is technically a 12 kW device, but of course this will depend on how much your electrical circuit can take. It can plug into a NEMA 10-50 OR A NEMA 14-50 wall outlet running at a 240V Voltage. The other end that plugs into the car is an SAE J1772 connector.
This should charge a Nissan Leaf with a 40 kWh battery pack in about 6 hours and that’s because of the 6.6 kw maximum power limitation on the on-board charger in AC Charging mode. You see, 11 kW chargers currently provide much more energy than the AC charger can take, that’s why most cars are also equipped with a port to connect to DC charging stations.
This is the only charger here that is not a Smart charger. There’s no connectivity and the way you interact with it to adjust the amperage or set a charging timer is through the use of RFID cards (tags, keys, you’ll find them under different names). The charging timer isn’t the same as schedule charging, it is basically just a delay timer that works in 1 hour increments.
This electric vehicle charger is IP56 rated so it will do fairly reasonable outdoor, it has overheat, overvoltage and overcurrent protection as well as flame resistance.

Single-Phase vs Three-Phase EV Chargers
Level 2 AC EV chargers can be operated with a single-phase or a three-phase power supply. Most Australian homes have a single-phase electrical connection, and so single-phase EV chargers are the preferred choice for residential applications. However, homes featuring a three-phase connection can have many benefits by installing a three-phase EV charging station.
If you are interested in learning more about single-phase and three-phase EV chargers, this is the right article for you. Here we will be explaining the basics of both types of power supplies, how to recognise each electrical connection in your home, the benefits of each charging type, and more.
What Is a Single-Phase Connection?
Residential dwellings that do not have a considerable electrical demand will most likely feature a single-phase supply from the grid, this is most likely the case for your home.
The distinguishing feature of a single-phase electrical supply is that it operates on two wires. The first is the ‘active’ wire which supplies the electricity to your home, while the second is the neutral wire acting as a return pathway for the current. The voltage between the active and the neutral wire for a single-phase installation should read 230VAC.
There is an easy way to determine if your home is powered by a single-phase power supply. At your switchboard, there will be only a single ‘main switch’ inside.
What Is a Three-Phase Connection?
Industrial and commercial applications will almost always feature a three-phase electrical supply, but there are cases in which a residential installation may require a three-phase supply to power heavy loads.
Instead of a single active wire, a three-phase supply utilises (you guessed it) three active wires. The voltage between an active wire and neutral should read 230VAC. However the voltage between two active wires should read close to 400VAC.
A home with a three-phase connection can handle three-phase loads that are balanced across all phases. Single-phase loads can also be connected to the circuit, but an electrician should balance the load as much as possible to avoid putting a strain on a single phase.
What Is the Difference Between Single-Phase and Three-Phase Charging?
Single-phase EV chargers only require one hot wire to operate the device and charge the vehicle. The power rate for a single-phase level 2 EV charger varies from 3.6kW up to 9.6kW; this would put a load of 15 amps up to 40 amps through a single-phase wire.
On the other hand, a three-phase EV charging station requires three hot wires to operate. This charger demands a balanced load from the power grid, dividing the electrical currents equally across all three phases. The power rate for three-phase EV chargers goes from 3.6kW up to 22kW, this represents a load of a three-phase current of 5.2 amps up to 31 amps.
Pros and Cons of Single-phase and Three-Phase Charging
Pros of single-phase EV charging:
- Single-phase EV chargers can be installed in most homes with any type of electrical connection.
- Chargers can deliver up to 9.6kW, more than enough to charge a single EV.
Cons of single-phase EV charging:
- Two EVs cannot be fully charged overnight.
- Charging a 60kWh battery can take between 6-8 hours.
Pros of three-phase EV charging:
- Cost of the charging unit is similar to a level 2 single-phase EV charger.
- The load is balanced, which is great for the electrical power grid and the quality of your home electrical service.
- Charge at a power rate of up to 22kW.
- Your home is future-proofed if you acquire a high-capacity EV charger. If your next EV charges at a faster rate than your current one, you will already have a suitable charger.
- Two EVs can charge at the same time at a maximum power rate of 11kW (22kW EV chargers).
- A 60kWh battery charges in nearly 3h.
Cons of three-phase EV charging:
- A three-phase electrical connection is required at the home.
- Most homes do not have three phase power, so an upgrade is likely.
- Installation may be a little more complex, and can be quite costly to upgrade your home
Should You Pick Single-Phase or Three-Phase Charging?
If your home has a single-phase electrical connection, which is most likely your case, then we’d usually recommend you keep a single phase charger installed. Upgrading the house electrical infrastructure from single-phase to three-phase is expensive, and sometimes not even possible (this will need to be verified by an electrician). In this case, a single-phase EV charger can do the work by easily charging your EV overnight at a power rate of up to 9.6kW.
Homeowners with a three-phase electrical connection do have a choice, but this one is simple to make.
Three-phase EV chargers demand a balanced three-phase load, which makes it perfect for a three-phase household connection. A level 2 single-phase EV charger connected to a three-phase installation, would put a strain on a single-phase of your home electrical system.
Several chargers sold in Australia have been designed for single-phase charging and a counterpart for three-phase charging. These are some of the best ones:
- Ocular LTE: This Australian company manufactures some of the best single-phase 7.2kW EV chargers and produces a high-quality 22kW three-phase EV charging station.
- Wallbox Pulsar Plus: This company produces many EV charging solutions. One of the best ones is the single-phase 7.2kW EV charger featuring Smart Solar charging and Power Sharing. There is a counterpart, which is the three-phase 22kW EV charger that also includes both features.
- Zappi: The Zappi EV charger is a Smart Charger that can integrate a solar array and a battery storage system to the charging platform. There is a 7.2kW single-phase EV charger option and a 22kW three-phase model with excellent specifications.

Can All EVs Get Charged With Three-Phase Charging?
All AC electric vehicle plugs feature a three-phase capability. This means that technically all EVs can charge with a three-phase charger, but not all EVs can charge at the high power rate delivered by high-capacity three-phase EV chargers. There are several EVs that limit AC fast charging at 11kW or less.
For instance, the Tesla Model 3 can charge at a maximum power of 11kW, so you could charge two Tesla Model 3s at home with a 22kW charger. The Nissan Leaf and the Mazda MX-30 also limit the maximum AC charging speed, but at 6.6kW. One of the EVs available in Australia featuring a 22kW onboard charger is the Audi e-tron EV SUV.
