Tesla Model S
Every New Tesla Owner’s Dilemma: Dual Chargers vs High Power Wall Connector (HPWC)
An analysis of the HPWC and Dual Charger options for charging the Tesla Model S.
When you purchase a car, you typically buy what’s on the lot and it’s either fully loaded or stripped down with the bare necessities. Custom orders are few and far between. With Tesla you almost always end up configuring the vehicle to your exact specifications. While they do have inventory cars for immediate sale, they’re often used vehicles with a previous life as a service loaner or test drive vehicle.
There are really 3 kinds of buyers for the Model S when it comes to options:
- Those who opt for every available option and price is not a factor.
- Those that go for the bare minimum options and stretch their budgets in order to get into the car. These are the owners with the stripped down Model S 60 kWh’s (or even 40’s!) with no Tech package etc.
- Those that are in between and select only those options that they really need in order to save money.
If you’re in category 3 then read on.
Two points that need to be considered when ordering a Tesla Model S is whether or not the High Power Wall Connector (HPWC) is really for you; a $1,200 option that provides two times the charging rate of the standard option.
The second point to consider is whether you want the on-board dual chargers,
another $1,500 option which allows twice the conversion capacity as the single charger when the power is available.
Originally the HPWC and Dual Chargers were a single option around $3,000 and later on Tesla split the options out. Why they did that is interesting and indicates that there maybe a reason for having dual chargers without the HPWC.

I drive a lot: 35K miles per year. Other than a relative who’s a full time truck driver, I drive more than anyone I know. I plan on driving my Tesla just as much. On a daily basis I range from 90 miles to 175 miles in a given day just based on my usual pattern of family shuttling and commuting.
Do you really need the Tesla High Power Wall Connector (HPWC)?
Tesla has a good charging speed calculator on their site. If you take a conservative 200 miles per day and charge on the “standard recommended” home adapter through a NEMA 14-50 outlet, you can replenish the battery capacity in 6 hours 48 minutes. This measure of time is somewhat misleading as Tesla tends to provide “best” numbers and, unlike an ICE car, charging from an empty battery state is faster than charging from 20% left. Assuming you don’t arrive home with 0 miles left, the time to charge could be a bit longer. Most people I know, once home from work, are there for a minimum of 8 hours thereby giving them a significant amount of time to charge up. While Tesla recommends the HPWC for anyone regularly driving over 100 miles a day, I think the guidance is incorrect and the HPWC is not needed for the most part.
That being said, there are possible edge cases where it could be needed:
- On-call type people that can come and go from the charge location with few hours each time and long times away from the charger. Doctors and other professions like that should carefully consider their patterns.
- People that can take advantage of time-of-use metering (discounted off-peak electricity rates) from their electricity provider. Here in Massachusetts you have to consume at least 2,500 kWh per month over a 12 month period to qualify and generally this doesn’t work for homeowners even with high energy consumption. My utilization can run as high as 2,296 kWh/month but this still wouldn’t qualify.
- The HPWC is one way to get a second charging cable. It’s not the most efficient way since a second mobile connector is just over half the price, so you’re better off buying that second mobile connector and leaving it connected in the garage.
- It’s for a business or public use environment. Here people need to come and go as fast as possible. Whether that’s your business or you decided to share your power via PlugShare or the like, then you’ll want to provide the fastest charge possible to get people moving on.
So you don’t need the HPWC. Also don’t forget that the HPWC requires a lot more power and will likely cost more to install than a standard NEMA 14-50. A NEMA 14-50 home installation can run between $1,000-$1,500 but this varies greatly depending on the distance that power lines needs to be pulled and the underlying power supply/infrastructure of your home set up. I was fortunate enough to have mine installed at $675 since, apparently, my infrastructure didn’t require too much of an upgrade.
Tesla Dual Chargers
If you don’t purchase the HPWC option do you really need dual chargers? Personally, unless you never plan on taking an extended road trip or don’t care about future proofing you car, the on board dual chargers could provide some tremdous value. It’s this very same reason why I modified my order at the last minute and added the dual charger option.
At home using a NEMA 14-50 or on the road using only the Tesla Superchargers network (ie, epic 12,000 mile Tesla road trip) you wouldn’t need dual chargers. The dual chargers provides no benefit in each of those scenarios.
However, by having the dual chargers, you’d be able to take advantage of several fast charge options out there while future-proofing your vehicle as public charging technology advances.
- Publicly available HPWC’s out there like those at a Tesla Store or Tesla Service Center or those shared by homeowners and businesses which will grow over time. To take advantage of max charge rates on these you need dual chargers. Not all HPWCs provide more than 40A though.
- Public EV Plugs (J1772) can go up to 70A. The number of these that are over 40A is very limited today but that is rapidly changing. To take advantage of max charge rates on these you need dual chargers.
- CHAdeMO outlets offer higher speed charging for those that can take advantage of them. Tesla has been promising an adapter for a while but has yet to deliver.
While dual chargers are an extra cost on top of an already expensive car, at roughly 1% of the cost of the car and potentially saving hours of frustrating wait time, I think the decision to get dual chargers is a no-brainer and provides some future proofing for the car. HPWC likely always an unnecessary expense.
Thoughts/comments? Would love to hear from you.
A Tesla owner who purchased a Model S Signature Edition, one of the final 250 units of the all-electric flagship vehicle that the company discontinued earlier this year, is attempting to sell the car despite a no-resale clause that prohibits reselling for the first year.
The car is being sold by J&S Autohaus in Ewing, New Jersey, and is priced at $260,490, well above the $159,420 that Tesla sold it for earlier this year.

To those who do not know, the Model S Signature was a highly exclusive, limited-run farewell variant of the Model S Plaid that was produced this year to mark the end of production of both the Model S and Model X, Tesla’s two flagship vehicles.
Limited to just 250 units with invite-only sales, it serves as a collector’s item celebrating the legacy of the Model S, which helped pioneer Tesla’s electric vehicle success since its 2012 launch.
It bundles top-tier performance with bespoke cosmetic and luxury upgrades, plus Tesla’s Luxe Package. Here’s what the Model S Signature has over the typical Model S Plaid:
- Exclusive Exterior – Unique Garnet Red Paint, matching door handles, gold Tesla “T” badges upfront, gold Plaid and Signature badging at the rear.
- Premium Interior – White Alcantara upholstery with gold piping/accents, gold Plaid seat badges, Signature-marked door sills, individually numbered dashboard plaque, gold puddle lights, special interior lighting sequence, and a custom Signature key fob.
- Performance Upgrades – Carbon-ceramic brakes with gold calipers
- Bundled Luxe Package – Full Self-Driving (Supervised), four years of Premium Connectivity, free lifetime Supercharging
- Performance Metrics – ~1,020 horsepower, sub-2-second 0-60 MPH, ~390-mile range
Tesla quickly introduced a No Resale Agreement for the Signature Editions of the Model S and Model X, which would penalize the seller for “the amount of $50,000 or the value received as consideration for the sale or transfer, whichever is greater.”
The company continues:
“If you sell or otherwise transfer the ownership of your Model S or Model X, the remainder of the Recommended Maintenance, Wheel and Tire Protection Plan, and Windshield Protection Plan will transfer automatically to the buyer. The Full Self-Driving (Supervised), Free Supercharging and Premium Connectivity will not transfer with the vehicle and will terminate once the ownership of the Model S or Model X is transferred.”
Tesla will likely come after the seller, especially as it has been about two months since Tesla launched deliveries.

Tesla makes the cut on California’s newest EV Rebate program
California just signed a $270 million EV rebate into law and it starts this summer.
California Governor Gavin Newsom signed SB 168 into law on Monday, July 13, 2026, creating a $270 million EV rebate program that delivers money directly at the dealership rather than as a tax credit applied months later. The program, called MyFirstEV, is funded equally by California’s state budget and participating automakers, with each contributing $135.5 million to make the math work.
The timing is directly tied to the loss of federal support when the $7,500 federal EV tax credit ended, removing the most significant consumer incentive that had driven EV adoption in the U.S. California, which accounts for roughly one-third of all EVs sold nationally, moved to fill that gap with a state-level replacement.
The rebate structure is straightforward. First-time EV buyers can receive $3,500 off any new battery-electric vehicle with an MSRP up to $50,000. Used EVs priced at $25,000 or below qualify for a $1,750 rebate. The credit is applied at the point of sale, which removes the friction of the old federal system where buyers had to wait for tax season to see the benefit. The program goes live later this summer, with the California Air Resources Board expected to release full participation details next month.

For Tesla buyers, the implications are mixed. The Tesla Model 3 RWD at $42,490 and the Model 3 Long Range at $47,490 both fall under the $50,000 cap and would qualify for the full $3,500 rebate for first-time buyers. The Model Y, which starts at $44,990 after Tesla’s recent price adjustment, also qualifies. The Model X, Model S, and Cybertruck all exceed the cap and receive no benefit. As Teslarati has reported, the program also includes a carve-out exempting California-based automakers like Rivian and Lucid from the price cap entirely, a provision that puts Tesla at a disadvantage since it relocated its headquarters to Texas in 2021.
Other qualifying vehicles include the Chevrolet Equinox EV, Ford Mustang Mach-E, Hyundai Ioniq 5, Kia EV6, and Volkswagen ID.4.

Trump’s invite for Elon just reshuffled Tesla’s big Signature Delivery Event
Tesla rescheduled its final Model S farewell to May 20 after Musk joined Trump in China.
Tesla has rescheduled its Model S and Model X Signature Edition delivery event to Wednesday, May 20, 2026, after abruptly calling off the original May 12 celebration. The event will take place at Tesla’s factory at 45500 Fremont Boulevard in Fremont, California, the same location where the Model S first rolled off the line in 2012. Invitees received a follow-up email asking them to reconfirm attendance and download a new QR code ticket, with Tesla noting that all travel and accommodation expenses remain the buyer’s responsibility.
The reason behind the original cancellation came into focus the same day it was announced. President Trump invited Elon Musk, Apple’s Tim Cook, BlackRock’s Larry Fink, Boeing’s Kelly Ortberg, and executives from Goldman Sachs, Blackstone, Citigroup, and Meta to join his trip to China this week for a summit with President Xi Jinping. The agenda covers trade, artificial intelligence, export controls, Taiwan, and the Iran war, following weeks of escalating friction between Washington and Beijing over AI technology, sanctions, and rare earth exports. Trump wrote on Truth Social, “I am very much looking forward to my trip to China, an amazing Country, with a Leader, President Xi, respected by all.”
Tesla launches 200mph Model S “Gold” Signature in invite-only purchase
The vehicles at the center of all this are the last Model S and Model X units Tesla will ever build. Priced at $159,420 each, the 250 Model S and 100 Model X Signature Edition units come finished in Garnet Red with a one-year no-resale agreement, giving Tesla right of first refusal if the owner decides to sell. As Teslarati reported, the Model S defined Tesla’s early identity as a serious luxury automaker, and the Fremont factory line that built it is now being converted to manufacture Optimus humanoid robots.
Musk’s inclusion in the China delegation drew attention given his very public relationship with Trump, and the invitation signals the two have moved past and past grievances. Trump originally brought Musk on to lead the Department of Government Efficiency following his inauguration, and despite a sharp public dispute in mid-2025, the two have appeared together repeatedly in recent months. A seat on the China trip, the most diplomatically consequential visit of Trump’s current term, puts Musk back at the table on U.S. economic policy at a moment when Tesla’s China revenue remains one of the company’s most important financial pillars.
