Very impressed with the performance of the plastic screw type bottle style jack. Was not expecting that.

Once again, the Japanese demonstrate their mastery. I was impressed by the overall load rating of that plastic jack. To be clear, you'd never get near that rating by using the jack, friction would likely weld those threads together long before you approached that load...

never get underneath a car with any of these jacks. use them to remove the wheel if you have a flat tire and then immediately put that wheel under the car so if the jack fails the car will land on the wheel rather than you.

The plastic one did fantastic, I assume it has to do with the design shape since cylinders are some of the most structurally sound designs

It would be nice to see the same jacks compared but with the force being applied via the jack mechanism itself instead of the press. I have a feeling that the plastic one would fail completely differently when the force is being applied via the moving threads.

Bro I don't have a hydraulic press at home 🤣

Not particularly surprised on the plastic bottle jack performance. From a physics performance, the bottle jack geometry (vertical support) is the strongest type of jack available. That's why inferior material can perform surprisingly well.

Roll up a single sheet of print paper and see how much weight you can put on it. That's the strength of this vertical support geometry in practice.

I have a feeling that the threads of the plastic one would give way sooner when trying to actually jack up the car

This video is surprisingly high quality, underrated YouTuber indeed

Why does Mercedes disappoint the viewers? Jacks are used for emergency tire change, so they are rarely used.
The Mercedes jack does what he is supposed to, to lift the car, including 50% safety weight.
But he weights only 2/3rd of the other jacks, meaning it spares ressources 😁 BTW, I'm not a Mercedes employee, and yes, I'm aware it is a bit of a paradoxon to talk about sparing ressources with a luxury car 😆

In future videos like this, I'd recommend summurising the results at the end in a table, like Project Farm does :)

I liked this video (full stop).  
But… Jacks are not used by extending to a given height and then gradually applying load. I’d be interested in how much the jacks can lift using their in-built mechanism. I’d guess that the threads on the bottle-screw jack might not work if extending against a large load. The other jacks might also have a different weakness(s).

That Mercedes Jack looks like a death trap….. when it slips….

As most others here I am astonished by the performance of the plastic jack, but I can also imagine how crappy the use of it is when you actually try to jack up a car. When in need of a good jack I think I would prefer the Nissan jack, which also outperformed by 155%. These jacks are easy to use even under load.

A plastic jack! Crazy, I didn't even know that was a thing.

And i'm sure everybody thought the plastic one would be the worst

Perhaps the greatest feature on this press has is it's very own drum roll

I am absolutely astonished by the performance of the plastic jack. I could almost trust that to jack up my pickup truck. Almost.
