The hydraulic bottle jack lifts, holds, and locks vehicles in place without jack stands. Properly fitting unibody framed vehicles, the Unijack is perfect for cars, crossovers, and small SUVs and trucks. 21" Lift range with 3 ton capacity.
Features:
Specs:
Note: This jack is designed to lift and stabilize 3 tons and should not be used to lift over that weight.
Begin using the Unijack by placing it on solid, level ground in a vertical position under the vehicle or object you wish to lift. Determine the best lifting point to support the bottle jack and line up the piston ram underneath it. Once everything is lined up correctly, turn the lever switch at the base of the piston clockwise to allow you to move the piston up and down. After you have the vehicle lifted to the desired height, the jack will automatically lock into place. The Unijack will then double as a jack stand to support the lift. To unlock the jack, simply turn the lever at the base of the piston counterclockwise and the hydraulics will slowly move in a downward motion.
Ratings & Reviews
This product broke after less than a year, used once. Definitely would not recommend.
Failed after three uses. Still waiting for a reply as to warranty repair or replacement reported before one year warranty period expired.

Im still enjoying everything purchased. Nothing but positive reviews for all.
Just the right size jack I need to keep in in fifth wheel.
Great jack, Solidly built. So far. haven't used enough to comment on longevity of this product.
I was amazed the product was shipped so quickly and received in just two days. Great Job etrailer... Product was packaged well and received perfectly. A great product...
Just got this today and its exactly what I ordered. Arrived in 3 days. Excellent customer service (Emily). Will continue to purchase items I need for my RV.
Well done etrailer team.
Perfect for stashing in a trailer in case of a road emergency. The only downside is that they like to be kept clean and dry which is not an insurmountable task.
Works great unless the load shifts slightly. If that happens this Jack gets in a bind and won’t go back down. This has happened to me four times. You then need some other way to raise the load to unbind this Jack. Others reported the same thing in reviews I saw before I bought it. But as long as the load stays straight this jack works fine and goes up really high. Plus it’s compact and doesn’t weigh much.
Great jacks for my travel trailer. It’s hard to use a floor jack then try to put a jack stand in the jack point. The Unijack solved that problem for me.
The jack worked as described, and is built very well. I use it to raise my travel trailer and with the built in jack stand you feel very safe in its use
Besides the fact the e-trailer has the best and highest quality products, the staff over the phone are as equally impressive. They have great customer service. The people are friendly, helpful, and inform you if your order is delayed and why. I have made several orders and each one was smooth and pleadant. I am a life time customer with e-trailer.
Wouldn't jack up anything, leaked all jack fluid out around the release valve, poor o-rings. Called the company that builds these three times, never answered the phone and never returned the calls.
No I would not but another one.

I hate to hear that you had this kind of experience with the jack. I know that the jack has a 1 year warranty that the manufacturer will honor. I would be happy to send the instructions to you.

Hello Jenny, I originally talked to someone at etrailer and was told I could return it to you. I didnt want to send the jack back just for that, I was hoping Powerbuilt could sent the o-ring but never got to talk to a person. I went to [online], got some o-rings and fixed it myself. Ive never had a problem with etrailer, I would never buy one again because of Powerbuilt. Thanks for the email Jenny, it shows etrailer still cares about their customers.
I am preemptively giving this jack five stars. I haven't had cause to use it yet but the peace of mind it gives knowing that I can jack up my single-axle trailer to change a flat on my own (if I ever get one) deserves the stars. Also, the customer service for the price match guarantee is the best!
The unijack is exactly what I need to lift a camper trailer to change a tire. The 21” lift with a few blocks allows for enough reach to the underbody frame placement which is recommended. The 9” base is excellent for stability and the extra lock adds to safety. I’ll be using it for my other various trailers as well. I ordered Monday night and received it Thursday morning. Great service. I believe Missouri to upper Michigan! I ordered mirror straps about a month ago with the same exceptional results. Thanks
We use them as jacks for our trailers and trucks. So much easier than carrying around floor jacks. They do need to be kept clean and dry or they will not be reliable.
We store these for emergency use in out trailer boxes. They add peace of mind for roadside tire changes.
They do seem to be sensitive to rust and abuse and need to be stored in a relatively clean and dry environment such as a trailer box.
My experience was outstanding. The product is more than I expected. I have a Jeep Gladiator with 40-inch tires and this jack will work perfectly if I ever need a tire change. What's nice is this jack came with a handle and most don't. The staff was exceptional to work with when I needed their help. The products I've ordered have always been quality products and this was no exception. I definitely will be ordering from you again.

Well, it has been a year since I bought your Power Built jack, and although I havent needed it for tire changing, I used it to change a spring on my dump trailer, that was filled with a yard of stone, and also to lift my huge doghouse and replace floor joists that had seen there better day. Just wanted to let you know of the other uses for this Jack!
Good design for all in one.
Love this jack!! It's VERY sturdy and has a clever easy to use, automatic safety lock. Finally I have peace of mind that I can remove a wheel from my single axle Flagstaff e-Pro, with ease. My axle is 12 inches off the ground. Not many jacks can handle that height as a starting point! This will stay permanently in my towing truck.
I have never seen a bottle jack with a built in stand. I think it’s a great! I love it! I haven’t had the opportunity to use it yet, I’m not complaining. It’s been said that it’s better to have it and not need it than to need it and not have it.
I haven't gotten a chance to use the jack yet, and that's a good thing on one hand. But looking it over this is exactly what I been looking for. All in one jack stand and jack. It'll work great for both my RV and truck. It is very durable and easy to use.
One improvement would be helpful. Provide a means to secure the 2-piece handle.
Otherwise, I really like the product.
