DeWalt makes a ton of money though selling cordless power tools and lots of expensive batteries.
They make these cordless?

Tesla Cybertruck On-board power is amazing! And surprisingly long lasting. Screenshot 2025-09-22 at 18.24.44

I've actually got that power station! Used it for portable and backup power using 4 of their biggest Flexvolt 15Ah batteries... I've actually been wondering how much range it would add to the Cybertruck on a full charge... might have to test that and see how many miles/percent it adds using up the batteries. I'm sure I'd lose some to heat and whatnot... might not end up much? But I wonder HOW much.

Could be an improvised range extender to keep in the bed :)

You would be adding probably less than 0.68% to your range.

If the Cybertruck had DeWalt 15 amp hour flexvolt batteries, it would amount to about 455.56 battery packs.

Is that a guess, or how did you get to to .68%? Thats sounds pretty exact. Grok just gave me the following:


"The four DeWalt 20V/15Ah FlexVolt batteries each hold 20 volts × 15 amp-hours = 300 watt-hours (Wh) of energy, for a total of 1,200 Wh across all four.


The Tesla Cybertruck has a battery pack with a usable capacity of 123 kilowatt-hours (kWh), or 123,000 Wh.


To find the percentage filled: (1,200 Wh ÷ 123,000 Wh) × 100 = 0.98%. This assumes perfect, lossless energy transfer, which isn't realistic in practice due to inefficiencies in conversion and charging."

So your .68% figure sounds pretty accurate accounting for energy lost during transfer. Not only that, but for it to charge and transfer all that capacity, the truck is probably eating more than that just during idle time charging. Lol

I wish companies like DeWalt would notice the use cases for CT onboard power and have some tool advertising regarding it. Maybe DeWalt could show a little love your way and get you that dust bag system. I'm interested in the scrap wood wall in the background, looked nice from what I could see.
Thanks! I'll likely show my tool room more in future vids. Done a lot of 3D prints and thing to line out the organization. That whole area I used reclaimed strips of barnwood on all the walls. I love how it turned out.

Competitor? I wasn't aware of the DeWalt line of trucks and grid-tied battery products aside from

As I posted before, a large, and I suspect more lucrative, part of DeWalt's product line is battery-powered cordless tools, and variations of batteries and chargers which power them. They also sell a selection of fossil-fueled generators. Cybertruck is certainly a competitor in supplying off-grid power for their tools. I don't imagine they would wish to advertise that. My guess is that it is a larger portion of their business than Cybertruck is of Tesla's

Their generators are just a licensed deal and don't take advantage of their battery systems in any particular way that I know of.

I usually expect you to be better informed. They make money on whatever they sell. Handing any of that market share to competitors reduces, revenues and profits. Obviously, Cybertruck provides grid-detached power that can replace the need for other portable sources for power tools, which is a major part of DeWalt's product line.

It would be counterproductive for them to advertise it. Do you think Tesla, if it advertised, would be featuring DeWalt generators? I can't see why you are arguing this.

...And anyone who thinks generators and batteries compete I think silly. They do different things.

Peanut butter and chocolate are both sweet treats, but they don't compete.

That is seriously out of touch with the current marketplace. I tend to agree with you technically and it grates that 1kWh+ battery packs with inverters are now ubiquitously marketed as "generators" but that's the fact of it. They both supply grid-detached electricity and so of course they compete. Cybertruck does that too, brilliantly, so it is an outstanding competitor. If you think making money through competitive marketing is silly you are not much of a capitalist.

There's no money to be made with this fake competition, except marketing guys getting paid to justify dumb ideas. That doesn't mean they will actually make more money by pretending to compete against big batteries. Just because marketing thinks something is competition doesn't mean it actually is.

The only real competition is in 'what fits in your cargo space' between like a Jackery or Ecoflow and a low-end generator. But Tesla doesn't make those. And DeWalt makes both these batteries and the licensed generators: Their license deal competes with their own product.

And DeWalt doesn't make home integrated generators, at all... And those actually work *better* with an integrated battery no matter what they are.

We agree technically, because it's true. Marketing is often silly. Generators and batteries work better together. A good battery set up means never wasting fuel idling the generator; a good generation set up means you don't need more battery than you can afford/is available. That's why I made the chocolate-peanut butter comparison. They don't really compete (someone buying one won't be happy with the other), and they're better together.
