Tesla Model S Fast Charging USB Port Hack

I recently came across a video online where Nick Howe, author of Owning Model S, introduced a device that could potentially increase the USB charging speed of smart devices when used in conjunction with the Model S USB ports. This was certainly intriguing especially having heard that the Model S USB ports were rated at different amperages. The closest USB port to the driver’s seat is rated at 2.1 amps while the port directly next to it – let’s call it the passenger side USB port – is rated at 1 amp.
I, for one, definitely want to maximize the charge rate from the driver’s side port so I decided to pick up the recommended device and put it to the test.
Measuring USB Power
Devices used for the test:
- Model S (production April ’14) with Firmware 6.0
- iPad 4, iPad Mini (original), and an iPhone 6
- Digital USB Volt/Amp meter
- PortaPow Fast Charge USB Adapter (universal)
- 2 USB cables for the Apple devices; one from Apple (standard cable) and one Amazon basics certified clone.
Disclaimer: my test was performed strictly using Apple iOS devices. It’s quite possible that Android based devices may see different results.
Theory Behind “Faster” USB Charging
Without going into excessive detail, smart phones and digital devices that transmit data can only charge as fast as the negotiated USB protocol allows for (USB 1.0 vs 2.0 vs 3.0). The concept behind the PortaPow adapter is that it removes the transmission of data when a smart device is plugged into a USB power thereby making the device receive charge at a much faster rate, and up to the power limits of the port itself.

USB Charge Results
The row in green represents the USB source where PortaPow was effective in providing a faster charge rate, which to my dismay only occurred when used with my MacPro USB 3.0 port.
Sadly, there were no benefits when pairing the PortaPow with the Tesla Model S USB ports. In fact, the PortaPow accessory actually reduced the charge rate by nearly 6% regardless of whether we used the driver or passenger side USB port.
Summary
I confirmed that both ports on my Model S charge at a rate of 1 amp, and not the 2.1/1 amp that some forum members (myself included) have previously reported. Actual measurements indicate that the PortaPow device is useless in the Model S. Skip it.
My recommendation is to get a good USB car charger that’s capable of charging at the maximum 2.1A rate. You can pick up a decent charger for under $20 that will actually do the job.

Tesla owner highlights underrated benefit of FSD Supervised

Elon Musk has been pretty open about the idea of FSD being the difference maker for Tesla’s future.
If Tesla succeeds in achieving FSD, it could become the world’s most valuable company. If it doesn’t, then the company would not be able to reach its optimum potential.
FSD Supervised’s safety benefits:
- But even if FSD is still not perfect today, FSD Supervised is already making a difference on the roads today.
- This was highlighted in Tesla’s Q4 2024 Vehicle Safety Report.
- As per Tesla, it recorded one crash for every 5.94 million miles driven in which drivers were using Autopilot technology.
- For comparison, the most recent data available from the NHTSA and FHWA (from 2023) showed that there was one automobile crash every 702,000 miles in the United States.
This morning, Tesla FSD proved to be an absolute godsend. I had to take my brother-in-law to the hospital in Sugar Land, TX, which is 40 miles away, at the ungodly hour of 4 AM. Both of us were exhausted, and he was understandably anxious about the surgery.

The convenience of…
FSD user’s tale:
- As per an FSD user’s post on social media platform X, FSD Supervised was able to help him drive a relative to a medical facility safely even if he was exhausted.
- During the trip, the driver only had to monitor FSD Supervised’s performance to make sure the Tesla operated safely.
- In a vehicle without FSD, such a trip with an exhausted driver would have been quite dangerous.
- “This morning, Tesla FSD proved to be an absolute godsend. I had to take my brother-in-law to the hospital in Sugar Land, TX, which is 40 miles away, at the ungodly hour of 4 AM. Both of us were exhausted, and he was understandably anxious about the surgery.
- “The convenience of sending the hospital’s address directly from my iPhone to my Tesla while still inside my house, then just a single button press once inside, and 40 miles later we were precisely in front of the hospital’s admissions area.This experience really underscores just how transformative this technology can be for society,” Tesla owner JC Christopher noted in his post.

Tesla Optimus “stars” in incredible fanmade action short film

There are few things that prove an enthusiast’s love towards a company more than a dedicated short film. This was highlighted recently when YouTube’s SoKrispyMedia posted a 10-minute action movie starring Optimus, Tesla’s humanoid robot, as well as several of the company’s most iconic products.
The video:
- Shot like a Hollywood action flick, the video featured a rather humorous plot involving a group of thieves that mistakenly targeted a Tesla Model 3 driver.
- The Model 3 driver then ended up speaking to Tesla for assistance, and some high-octane and high-speed hijinks ensued.
- While the short film featured several Tesla products like the Model 3, Superchargers, and the Cybertruck, it is Optimus that truly stole the show.
- Optimus served several roles in the short film, from an assistant in a Tesla office to a “robocop” enforcer that helped out the Model 3 driver.

Cool inside jokes:
- The best Tesla videos are those that show an in-depth knowledge of the company, and SoKrispyMedia definitely had it.
- From the opening scenes alone, the video immediately poked fun at TSLA traders, the large number of gray Tesla owners, and the fact that many still do not understand Superchargers.
- The video even poked fun at Tesla’s software updates, as well as how some Tesla drivers use Autopilot or other features without reading the fine print in the company’s release notes.
- The video ended with a tour de force of references to Elon Musk products, from the Tesla Cybertruck to the Boring Company Not-a-Flamethrower, which was released back in 2018.
