Tried it. Worked great.

i have used it one since February purchase. worked perfectly.

The device works as well as previous versions I own with a slightly improved design, but the company appears to cheaping-out by supplying a flimsy plastic bag to store the Gooloo device instead of the excellent compact carry case previously supplied with the product.
The flimsy bag is pretty much useless and does protect the Gooloo device sufficiently.
I won't be buying anymore Gooloos if they continue to ship with this horrible storage bag or they send me one of the quality storage cases.
Benjamin L.
Great product, light weight, robust, light works well. Only reason o didn’t get 5 stars, didn’t come with the promotional items ( tire pressure tool)
Martin K.
Well, thank you for a good and wonderful product. My story is that my truck was frozen from -40 weather. Then a stranger named Tyler came to my rescue with his GOOLOO starter / changer. My battery was dead and frozen and after 2 attempts it started right up. Tyler had gotten his as a gift from his Dad. I thanked him many many times and noted the name of the device and the power out put. I then searched on the web and finally found it and purchased it.
So my car was dead and frozen also from the -40 weather and I hooked up the GOOLOO and one turn of the key and it started up, no hesitation. So yes I would recommend your product to anyone who is looking for a starter booster machine.
Ron B.
Customer service is poor
Promotions items supposed to be included were missing...ie. free fast charger and tire inflator.
Vinothan U.
I bought a booster they shipped it to someone else and did not give me the refund or the item
Phil R.
So far it is functioning as advertised. I have not needed to boost with it yet but it seems like a quality piece and has several outputs that can charge 4 or 5 things all at once plus the low current mode for really small devices.
John D.
I have used the GTS4000 to boost our sons car, it has always worked flawlessly, and so I bought two more , one for my son , so je doesnt have to borrow mine, and one for my nephew.
Myles W.
Works as expected. Only had it for 4 days and used it already. Way faster than jumper cables

I just got my gooloo looks pretty solid and heavyI' m happy. Can't wait to use it this winter. I will give another review after my first use.
Michael M.
Best value, excellent product!
Tae Y.
This is my 4th one I am buying.
I ended up giving away as a gift and they love them all the way so as I do too...ans that's why I ordered my 4th one too.
It's the best one I got...
Jean L.
I purchased the GT4000S for many pusposes, among which was feeding my CPAP. I learned afterwards this device is not compatible with a CPAP. GOOLOO kindly accepted that I return the GT4000S and refund me, and sold me a GTX280 which is good for feeding my CPAP. I am now set for all the purposes I intended to use my power pack for, and I am very satisfied.

Excellent quality. Very impressed. Arrived very quickly. I use on my boat and to charge my devices.
Thank you

The only thing is I can't figure how to charge it
MARTIN H.
This is the second GooLoo GT4000S I ordered. It has proven to jump start a UTV of mine where other jump starters could not do so. I first saw this GooLoo review via a youtuber "Chickanic" who repairs lawnmowers, chainsaws, etc. and I have been impressed thus far.

The Gooloo Jump Starter has worked amazing! It has jumped my battery immediately, and has saved my a lot of time and grief. I don't have to wait and be dependent on someone to call or ask a stranger for help. I would recommend this product to everyone who has a car.

Only used it a few times thus far. And those few times I was impressed, compact and lite, flash light isn't that bright. But bright enough to illumate working area. Great Item, super fast shipping.

My car wouldn't start in the super cold winter days, but this brought it right to life! Easy to use, store, charge. The only thing is that you can't keep it in a hot or cold car.

This is such a handy thing to have around. Takes up no space. Can start your car or truck, and then charge all your devices. Totally worth the money.

I use this to start my generator when the power goes out. I sometimes have to use it to start my riding lawn mower and yesterday, for the first time, used it to jump start my wife's car. It's very easy to use and very reliable.

Thankfully I haven't had to use to to jump start my car but have used it to recharge my phone in a power outage. Owning this has given me peace of mind that I have a way to jump start my car by myself with ease as well as recharging other electronics in an emergency.

I used the gooloo starter to jump a dead motorcycle battery and it worked like a charm. I haven't needed it for my cars yet, but I plan to always have it handy during road trips, especially when I'm traveling in my minivan camper. When you're out in the boondocks, far from a garage or even AAA, this product is great for peace of mind. You don't need another vehicle to jump your battery. And if you happen upon another traveler with battery problems, you can be a Good Samaritan and help them out. Sturdy construction, several jumps possible on one charge and since I have a power station, recharging via USB is a breeze.

1 week after i Received it my 85 year old father needed

think I would ever use it.I had him going in 3 minutes plus
where it was parked you couldn't use jumper cables.
I love it it works great!
Paula Stop
We bought it to have just in case and needed it a few days after it arrived. Really easy to use and we liked it more than a more expensive model we bought before. Liked it so much we got another one for a different car.

One of the best purchases we have made. Bought for our boat and have now used multiple times on our Titan Truck when there was a computer issue causing the battery to fail. Also used on a few friends cars. Still haven't needed on the boat but after seeing how great it works we almost bought a second one. The price is great and it out performed our expectations.

?I use this mainly for jumping my vehicle when the battery dies. As you can tell from the video, it works like a charm. 0-100 real fast. Well, at least fires it up right away. No need to let it set on the battery. Just plug, start, unplug and go. A must have in your car. I've used it to help start other peoples vehicles in cold weather too.

Very compact & portable and comes with nice semi-hard carrying case. Easy to use , comes with built-in flashlight in case your caught in the dark. Great to use as a battery source for charging phone/tablet or whatever device. Enough cold cranking current for most vehicles. And less expensive than other battery jumpers.
J. Thompson
We bought one a few months ago just in case. Since the initial purchase we used it 3 times. Impressive to the point that we ordered another for every vehicle in the fleet. Simple, Lights to indicate proper connects and display with charge status. It simply works and better than expected.
Ava
?Bought to start lawn mower as battery was not charged every so often. I've started it six times now still 100% charge. Very good voltage upon start. Like if I had a brand new battery. Don't I'll ever use the light but it's bright enough to see what you are doing if you were to get stuck at night. All in all, I believe this is a good buy.
Jeremy P.
It is very compact. But packs a large punch. Was able to jump start my Silverado 6.0, with a bad battery, a couple times on one charge. Packs nicely in the provided case.

I initially wrote a poor review but need to edit because the company made things right. My first unit would not hold a charge.

Got our SUV started back up when we found the battery died. Was able to get my kid to work.
Update...issue with battery so this has kept my SUV going just about every day. No complaints! This has been been a job saver!

This unit look like it had a lot of promise. I had it charged up sitting in my truck a couple of weeks. Went to take it with us off-roading for an emergency and the thing was completely dead, zero. Charged her up going to keep an eye on it but not good for emergency
