YATOINTO Porta Power Kit, 20 Ton Low Profile Hydraulic Jack with Manual Hydraulic Hand Pump Multi Section Jack, Kit of Porta Power，Mini Hydraulic Lifting Cylinders, Manual Low Profile Jack

4445 pounds not big enough to be twenty ton.

This is a cheap Portapower, and I mean that in the quality sense as well as the cost.I use these things to jack up equipment and level building floors. Much safer than a bottle jack. On the other hand, they are NOT for jacking up vehicles. Not near enough throw, and they have a narrow base, so a vehicle can roll off and drop.This one gets the job done, but it has some shortcomings...To start with, it did not function at all out of the box. The pump had air in the cylinder and wouldn't work. Had to put the ram on the floor, the pump on end up high, and pump like crazy to get the ram to extend. Let it back in, and repeat several times to get the air out of the system. It now works.The ram Extends about 1-1/8 inch max. It does not have a spring return, so if it doesn't have a load on it to push it back down, you have to push it in yourself. A bit unusual, but just a minor inconvenience. It did not leak down under load, so that's good.The pump is bare bones. The build is light, and the fit and finish is only adequate. The paint is chipping off, and some of the exterior parts are very poorly machined. It works, it's not leaking, so I can live with ugly.The label says it holds 300 CCs of oil, but I tested it with another ram I have that requires 200 CC to fully extend, and it only made it half way, so a lot is missing in the one I got. I think I know why there was air in the system. No oil in the packaging, so it came that way from the factory. It has enough to fully operate the ram it came with, though.There is no provision to add hydraulic fluid, or check the level. It looses a bit every time the ram is disconnected (that's what is all over the cardboard in my pictures), so it will eventually require some. Not really sure how I'm going to get it in there since mine needs it now.It comes without any sort of storage case. Part of what keeps the price low.All that said, it works after a bit of fussing, and it is very inexpensive. The pro ones we use at work cost four times as much as this kit for just the pump with no rams. It you are going to use this only occasionally, it's a serviceable unit, and it won't break the bank. I rated it accordingly.

I was pretty excited to receive this item because I don't have a low-profile cylinder for my 4-ton porta-power kit. Unfortunately, It was disappointing to me in a variety of ways. This '20-Ton' unit is about half the size of my 4-Ton porta-power. Maybe it uses magic physics, or maybe it's incredibly over rated.Specifically, my issues:First, it uses the opposite gender connector as my 4-Ton set from the tool store. So I can't use the YATOINTO pump on my tool store hydraulics, and I can't use the YATOINTO low-profile cylinder on my tool store hydraulic pump. I am going to see if I can get some sort of adapter to let me at least hook up the cylinder to my 4-Ton pump.Second, the foot on the back of the YATOINTO pump housing spins. And it's infuriating because you can't keep the pump in one place while operating it with just one hand. And the pump wants to fall over while you are applying force to the handle. Just a terrible design in my opinion.Third, I used this to apply persuasion to a wood beam under the house, and it worked smoothly and with relatively low effort, but it only worked that one time and never again. After I released the valve to lower the cylinder, the pump never produced any action at the cylinder again no matter what I tried. I can't narrow down the problem because the connector is backwards from the rest of my hydraulic tools. It's after 30 days, so I won't be getting any support.It is a hydraulic device, so it's not rocket science. It probably just blew a seal. But I don't have time to mess with it right now, especially when my existing porta-power set works.My 4-ton unit from the tool store has had the you-know-what beaten out of it for close to 15 years, and it's never had a failure. Maybe I'm just the lucky guy that got the defective YATOINTO porta-power . The price on this unit is low, but despite that, I can't recommend it based on my experience.

Low profile jacks are lightweight and easier to maneuver, especially under a vehicle. If you only need to jack up a vehicle a few inches to change a tire... this is perfect. However, because the case containing the cylinder is low profile, the cylinder and only extend so far... about the height of the container itself. You may need to use blocks if planning to jack anything further than case height. I will say it's a very powerful jack for such a small profile and is easily used... very intuitive and no real instructions needed.

The low-profile hydraulic jack is a marvel of engineering, designed to effortlessly lift and support heavy loads with utmost stability. Its robust construction and 20-ton capacity make it an indomitable force capable of tackling a wide range of lifting and pushing applications.
