Tesla EV Charger Reviews

About Tesla

Tesla Wall Connector

Tesla is one of the largest manufacturers of EVs in the world. At the start of 2024 they had made more pure electric vehicles than anyone else. BYD now has them beat, but second biggest is still huge.

In addition to making EVs and home batteries, Tesla has also manufactured a vast number of home EV chargers. Their latest model is the Tesla Gen 3 Wall Connector and this page will tell you all about it.

There are some good reasons to like the Gen 3 Wall Connector…

• It works with all modern EVs – not just Teslas

• Its price is competitive

• Enough have been sold to show it’s reliable

• Its 4 year warranty isn’t bad for an EV charger

But you can’t have all that without expecting some sort of trade-off and the Tesla EV charger does have a major drawback…

• Not able to smart charge

This means it can’t be set to charge an EV only with surplus energy from rooftop solar. Because this is normally the cheapest way to charge it’s a major drawback. But if you don’t have a problem with this, then the Tesla Gen 3 Wall Connector may be worth your hard earned money. Or even better, your lazily earned money – if you’re lucky enough to have any.

We Have A Write-Up

If you want to read about the Tesla Wall Connector we have a comprehensive blog post on it: Should You Buy A Tesla Wall Connector As Your EV Charger?

I recommend checking it out because it goes into a lot of useful detail and is likely to answer any questions you have. It’s also a pleasure to read – and I’m not just saying that because my boss wrote it.

Full disclosure: It is one of the reasons why I’m saying that.

This page mostly summarizes the post’s main points.

Not Just For Teslas

Those with a healthy level of paranoia may be wondering if the Tesla Wall Connector only works for Tesla vehicles. The good news is there’s nothing to worry about. Provided your EV has a ‘type 2’ AC charging socket you are good to go and every new EV sold in Australia since the start of 2020 is required to have one.

Single-Phase Vs. 3-Phase

The Tesla Wall Connector comes in single-phase and 3-phase versions and, unlike many EV chargers, there’s no difference in price. But note that 3-phase chargers require more work to set up, so there can be a difference in installation cost.

If your home has single-phase power then you can only use a single-phase EV charger. If you have 3-phase power then you can choose between the two. Generally, I’d recommend getting the 3-phase version as it can provide nearly 50% more power. But a 3-phase charger can add $400 or more to the installation cost and how much you value being able to charge up to 3.6kW faster.

Power Output

The maximum kilowatts (kW) of power the charger can provide depends on the type:

• Single-phase Tesla Wall Connector = 7.4kW

• 3-phase Tesla Wall Connector = 11kW

While the 3-phase one can provide considerably more power, the current Gen 3 version of the Wall Connector is not impressive compared to some other chargers which can provide 22kW. But because most EVs can only accept 11kW or sometimes less, not being able to provide more than 11kW isn’t a drawback for most EV owners.

Range Per Hour

Tesla has a table on this page that gives how many km of range Tesla vehicles will gain from an hour of charging at 7.4 or 11kW. For example, it says a Tesla Model 3 will gain 75km an hour when charged at 11kW. But Tesla is well known for dishonesty when it comes to the range of their vehicles and the European EV Database says it will actually gain around 68km of range. That’s around 90% of Tesla’s figure.

While the exact amount will depend on the vehicle, generally, you can expect 40+km of range per hour when charging at 7.4kW and 60+km at 11kW.

Cable Length

Not every EV charger comes with a charging cable, but the Tesla Wall Connector has an impressively long one. At 7.3m it’s long enough to potentially let you charge a car that’s behind one parked in front of the charger. This is an important consideration for some homes with two EVs or when EV driving guests arrive.

Operating Temperature

The Tesla Wall Connector’s operating temperature range is from -30 to 50 degrees Celcius. But, according to its operating manual, as it approaches its maximum operating temperature it will start to “derate” and reduce the maximum amount of power it can provide. Depending on conditions, this derating can start at as low as 35 degrees Celcius. Derating is likely to occur sooner with the 11kW 3-phase version than the lower power 7.4kW single-phase version.

Because of this, it’s very important to locate EV chargers in the shade whenever possible. If a sunny location is the only good option then I strongly suggest giving it a shade cover.

While derating at as low as 35 degrees is not good for Australian conditions, it’s not unusual for EV chargers.

Installation Location

The Wall Connector’s Ingress Protection rating is IP55. This means it can resist storm driven rain from all directions and can be installed outside. But, as a precaution, you should never intentionally spray it with water. As mentioned, it’s best to install it out of direct sunlight.

It’s Got Guts

It’s Not Smart

The Tesla Gen 3 Wall Connector is not capable of smart charging. This means it won’t be able to charge your car using only surplus energy from a rooftop solar system. As this is normally the cheapest way to charge an EV it can be a huge drawback. Of course, if you don’t have solar it’s not an issue. But not having solar is an even larger drawback, so you have my sympathies if that’s the case.

There are ways to work around this. With most EVs you can set when they charge and how much power they draw and this can be used to try to maximize the amount of solar power they use. If you don’t mind paying a subscription, you can also use an app such as Charge HQ to help do the same.

But one simple solution I think works well is to just have a large solar system and charge in the middle of the day.

Cost

At the time of writing this in January 2024, the Australian Tesla store is selling the Gen 3 Wall Connector for $750. Installation can add considerably to this cost. Note you’re not allowed to install these things yourself without suitable qualifications. Rather than buying one from the Tesla shop, I recommend getting a Wall Connector through your installer so they will be responsible for its warranty. This can make getting problems fixed much easier.

Installing an EV charger isn’t cheap and Tesla says getting Wall Connector installed will knock you back $750 to $1,500. This range is realistic. Installations that are straight forward and single-phase will be towards the lower end, while more complex and 3-phase ones will be towards - or sometimes past - the higher end.

Colours Are An Optional Extra

Just like with Tesla cars, if you’re willing to pay extra you can get one in a colour other then white. For $140 you can get different coloured covers for the Wall Connector. The choices are black, dark blue, red, and metallic. But if it’s going to be installed in the sun, I recommend sticking with its original off-white cover, as it might help keep it a little cooler.

Warranty

The Wall Connector has a 4-year warranty. This seems pretty lousy, given that Tesla also makes Powerwall batteries that are far more complicated and have 10-year warranties. But most EV chargers only have 2- or 3-year warranties, so compared to the competition, it’s considerably better than average.

Because many Wall Connectors have been produced, if they had serious reliability issues we probably would have heard about it by now. This makes me optimistic that, in normal household use, they’ll last much longer than 4 years.

My Conclusion

Given what else is on the market, the Tesla Gen 3 Wall Connector looks like a good choice – provided its inability to smart charge is not a drawback for you. But if you can do without the ability to charge cheaply in that way, then it’s probably not a bad choice for a home EV charger.
