High-voltage outlets, smart chargers, money-saving utility programs: what to know about charging EVs at home
4 min
Things I miss about my local gas station:
…
That’s it. That’s the list. OK, fine, I did enjoy the communal squeegees.
This week marks six months since the grand opening of my home electric-vehicle charging station. Congrats to the whole team! (Me and my electrician.) Located between my garage door and recycling bin, it’s hard to beat for the convenience. And also the price.
If you’ve followed my ad-EV-ntures, you’re aware of my feelings about the hell that is public EV charging , at least before Tesla started sharing its Superchargers with its rivals. Truth is, I rarely go to those public spots. The vast majority of EV owners—83%—regularly charge at home, according to data-analytics company J.D. Power.
I already discovered many EV virtues , but I didn’t quite grasp the cost savings until I tallied up half a year of home-charging data. In that time, I spent roughly $125 on electricity to drive just under 2,500 miles. In my old car, that would have cost me more than twice as much—assuming gas held steady at around $3.25 a gallon . And I was charging through the winter, when electricity doesn’t stretch as far in an EV.
Rebates and programs from my state and utility company sweeten the deal. So I will be able to take advantage of discounted electricity, and offset the cost of my charger. The same may be available to you.
But first, there are technical things to figure out. A 240-volt plug? Kilowatt-hours? Peak and off-peak charging? While other people are in their garages founding world-altering tech companies or hit rock bands, I’m in there finding answers to your home-charging questions.
Sure, you can plug your car into a regular 120-volt wall outlet. (Some cars come with a cable.) And sure, you can also simultaneously watch all of Netflix while it charges. It would take more than two days to fill my Ford Mustang Mach-E’s 290-mile battery via standard plug, known as Level 1 charging.
That’s why you want Level 2, which can charge you up overnight. It requires two components:
• A 240-volt electric outlet. Good news: You might already have one of these higher-powered outlets in your house. Some laundry dryers and other appliances require them. Bad news: It might not be in your garage—assuming you even have a garage. I realise not everybody does.
Since my suburban New Jersey home has an attached garage, the install process wasn’t horrible—or at least that’s what my electrician said. He ran a wire from the breaker panel in the basement to the garage and installed a new box with a NEMA 14-50 outlet. People with older homes or detached garages might face trickier wiring issues—more of a “Finding NEMA” adventure. (I apologise to everyone for that joke.)
My installation cost about $1,000 but the pricing can vary widely.
• A smart charger. Choosing a wall charger for your car is not like choosing one for your phone. These mini computers help you control when to start and stop charging, calculate pricing and more.
“This is not something where you just go to Amazon and sort for lowest to highest price,” said Tom Moloughney, the biggest EV-charging nerd I know. On his website and “State of Charge” YouTube channel , Moloughney has reviewed over 100 home chargers. In addition to technical measurements, he does things like freezing the cords, to see if they can withstand wintry conditions.
“Imagine you are fighting with this frozen garden hose every time you want to charge,” he said.
One of his top picks, the ChargePoint Home Flex , was the same one my dad had bought. So I shelled out about $550 for it.
Just remember, if you want to make use of a charger’s advanced features—remote controls, charging updates, etc.—you’ll also need strong Wi-Fi in your garage.
I hear all you money-minded WSJ readers: That’s at least $1,600 after getting the car. How the heck is this saving money? I assumed I’d recoup the charging-equipment investment over time, but then I found ways to get cash back even sooner.
My utility provider, PSE&G, says it will cover up to $1,500 on eligible home-charger installation costs . I just need to submit some paperwork for the rebate. In addition, New Jersey offers a $250 rebate on eligible charger purchases. (Phew! My ChargePoint is on the list.) If all is approved, I’d get back around $1,250. Fingers crossed!
I didn’t know about these programs until I started reporting on this. Nearly half of home-charging EV owners say they, too, are unaware of the programs offered by their electric utility, according to a 2024 study released by J.D. Power . So yes, it’s good to check with your provider. Kelley Blue Book also offers a handy state-by-state breakdown.
Now I just plug in, right? Kinda. Even if you have a Level 2 charger, factors affect how many hours a fill-up will take, from the amperage in the wall to the current charge of your battery. Take Lionel Richie’s advice and plan on charging all night long .
It can also save you money to charge during off-peak hours.
Electricity costs are measured in kilowatt-hours. On my basic residential plan, PSE&G charges 18 cents per kWh—just 2 cents above the 2023 national average . My Mustang Mach-E’s 290-mile extended-range battery holds 91 kilowatt-hours.
Translation: A “full tank” costs $16. For most gas-powered cars, that wouldn’t cover half a tank.
And If I’m approved for PSE&G’s residential smart-charging plan, my off-peak charging (10 p.m. to 6 a.m. and weekends) will be discounted by up to 10.5 cents/kWh that I’ll get as a credit the following month. I can set specific charging times in the ChargePoint app.
Electricity prices fluctuate state to state but every expert I spoke to said no matter where in the country you live, home charging should cost less than half what gas would for the same mileage. (See chart above for a cost comparison of electric versus gas.) And as I’ve previously explained , fast charging at public stations will cost much more.
One big question: Am I actually doing anything for the environment if I’m just taxing the grid? Eventually, I’d like to offset the grid dependence—and cost—by powering my fancy little station with solar panels. Then, I’ll just be missing the squeegee.

Apple’s growth engine is showing signs of slowing, as rising costs, weaker services growth and AI competition challenge its profitability. With John Ternus taking the helm, the pressure is on to reignite innovation and sustain investor confidence.

The Apple growth and profit machine is wavering, and the boost from price increases might not be enough to keep it going at historic rates. That dials up the pressure on Apple’s new chief executive, John Ternus.
The company saved the bad news for its earnings call, an hour after it posted its results for the September quarter, projecting that for the current quarter its high-margin services business will continue to slow and that its widely watched gross profit margin will continue to fall.
Apple AAPL -1.83%decrease; down pointing triangle shares had been flat in post-close trading but declined as much as 4% after the company made the projections, which fell short of Wall Street estimates.
The impact of high memory costs are weighing even more heavily on the company, Ternus and Apple Chief Financial Officer Kevan Parekh said on the company’s earnings call. Apple has stockpiled cheaper components purchased earlier, but those inventories are dwindling.
When Ternus took over as Apple’s third chief executive of the past 29 years on Sept. 1, he inherited sky-high expectations. The men he followed were among the most successful company leaders in American business history. Steve Jobs revolutionized consumer devices multiple times. Tim Cook expanded Jobs’s creation to spectacular heights.
The expectations are reflected in Apple’s huge valuation. Oppenheimer analyst Martin Yang noted that Apple stock trades at 36 times next year’s expected earnings, a premium to the overall market, even though its earnings are only expected to grow 1%, which is slower than its tech peers.
“We see insufficient upside to justify the premium,” Yang wrote in an investor note, adding that Apple needs to boost iPhone sales growth and turn around its slowing services business to make him more bullish.
Investors have bid up Apple shares because it has been a port in the AI storm—a reliable and capital-efficient business that stands apart from rivals which are spending hundreds of billions of dollars racing to the AI frontier.
While others invest in data centers, Apple has been pouring its own cash into buybacks and dividends. But that safety may be challenged if Ternus can’t speed up Apple’s innovation engine.
Apple’s lagging performance in AI was evident when its new “Siri AI” chatbot arrived this past quarter. Its long-maligned assistant was already stale the day it arrived, surpassed by agents such as Instinct and Muse that can complete multistep tasks for consumers, while Siri still sets kitchen timers.
Apple needs to give people reasons to buy its devices as they get more expensive. The company raised prices across the board last quarter to help offset higher costs. Without compelling new features, a big question is whether consumers will slow the frequency of iPhone upgrades.
The new iPhone Duo appears to be a bright spot. Consumers are scooping up the $1,999 foldable smartphone despite mixed reviews—so many that Apple can’t keep up with demand. Shipping dates jumped out to January soon after the device went on sale, a disappointment for the normally reliable Apple supply chain.
Apple said its revenue grew 12% in the September quarter, slightly ahead of Wall Street’s expectations. Its widely tracked gross profit margin, at 47.9%, also came in just ahead of analyst estimates.
Apple will need to find new growth avenues because a reliable engine during the Cook era—the services business—is slowing. Courts and regulators worldwide have limited Apple’s ability to charge developers big fees to distribute apps through its App Store, the biggest component of the company’s services segment.
One of its most lucrative App Store fee generators has been the ChatGPT app from OpenAI. Around the time Apple accused OpenAI of trade-secret theft this past summer, OpenAI began redirecting potential subscribers to pay via its website instead of the App Store, skirting Apple’s tollbooth.
Apple’s valuation has bumped up against a ceiling in recent weeks. Six times it traded above a $5 trillion market capitalization intraday before finally closing above the threshold, which it has already fallen back below.
News Corp, owner of The Wall Street Journal, has a commercial agreement to supply news through Apple services.
