Tesla didn’t sell this man a range extender, so he made one himself and managed to achieve a miraculous result.
EVs are often a great choice for many drivers, with the automotive world recently seeing a trend in the number of car owners shifting from gas to an electric power train.
However, an issue can sometimes come with the amount of range on offer with some EVs.
So, after getting stuck into creating this range extender for his Cybertruck, this man has shared his success story.

This homemade range extender landed a Tesla owner with a sweet result on the open road
When it comes to the Cybertruck, there are many positives to the EV.
From special driving modes to its jagged design, which means it can tackle terrain easily, there are many ways in which the truck excels.

But this owner wanted more range with their truck, so they turned to DIY.
It’s important to note here that plans for a Cybertuck range extender were actually halted, so this owner saw it as a chance to get creative.
Facebook user Neil Dillingham revealed the invention online, and other gearheads simply couldn’t get enough.
“Tesla wouldn’t sell me a range extender… so I built my own! 40kw giving me just short of 100 miles of extra range. Charging at 48amps to the truck,” he noted.
Neil went on to explain that he can recharge his extender by using a Tesla wall charger, Cybertruck outlets, up to 24kw of solar, some limited household outlets and even an ‘old school generator’.
“Took me 4 months to perfect the combination of inverters chargers batteries and cables.
Total cost of parts was around $11k and I can completely uninstall it myself in less than 45 minutes,” he further detailed in the post.

And, after others caught sight of the extender, they were in awe.
“Damn, that’s really awesome!!! You’re really good at this stuff!” said one social media user.
“I’m going to call you Doc from Back to the future,” said another EV enthusiast.
“I think this is going to be something that a lot of people would want,” added a third impressed gearhead.
Others were curious if it could charge whilst on the go, but Neil explained that it sadly wasn’t yet possible.
The Cybertruck is a popular EV in more ways than one
Thanks to Tesla’s creation of the EV pickup truck, it has enabled users to test out their Cybertrucks in a variety of different creative ways.
Thanks to the shape of the vehicle, one man conducted the first real-world wade test on Cybertruck to see if it really could be a ‘boat’
Plus, another owner went one step further, with the YouTuber attempting to live in a Cybertruck to see how practical it actually was.
