Ronie R.

used it twice already, it's great and easy to use!

Brett F.

Works great. Very intuitive

john w.

Great product

Wilf G.

Features look good but purchased after my dead battery incident and have yet to give it a thorough test.

DAVE W.

I bought 1 about a month ago, I boosted several cars with it. It worked flawlessly. Then I boosted my 2008 5.9 Cummins Ram. It was stone dead, in January in the freezing cold. Worked like a champ. I was so impressed I bought a second one!!

Doug R.

Product as described, delivery was prompt & happy with purchase….works like a charm.

Devon D.

Right out of the box impression, this is a solid unit. Very well made, the GT4000 looks and feels like a very quality built product. The unit arrived with an 80% charge, and charged up to 100% impressively fast with a 45w charger. The case is custom fitted to hold the boost pack snuggly and securely for storage, has plenty of room for accessories, and more. I am looking forward to a dead battery so I can put it to the test

Tom T.

Looks great but haven’t used it yet

Roy V.

Seems good, haven't used it yet

Bernard P.

powerful and light

Larry P.

Nice unit as long as it works in the cold. I live where it can be -25C so I guess we will see if it works

Nick I.

Works good best value for your money

Darrell P.

Cant really say how good it is boosting the car because I haven’t tried it out yet. But the packaging and the product are very impressive and I am hoping it proves to be a wise purchase

Sylvain L.

Good product.

Jason C.

I received the GT4000 about 2 weeks ago. The product arrived promptly after ordering. Packaging, communication from Gooloo and the condition of the product on arrival was very good. The GT4000 appears to have been well thought out and manufactured to a high standard. It comes with a plethora of cables to keep it charged up and the user in a good place. To date, I have only had to jump start a motorbike and the GT4000 worked flawlessly. We're now entering winter here and with several ATV's, boats and vehicles to keep moving, having this jump starter is a must have for our active family...

Tyler P.

Fast shipping and product is exactly as described. Haven’t used it yet. But it looks like a solid piece.

Louis P.

Works well ! As described, was shipped promptly

Mike E.

Self heating works. I will test it again when winter arrives.

Richard M.

I use it regularly but this the 3rd one Ive bought and should have gotten a better deal. When i order again i expect a better price.

Andy M.

Well had to use mine on my VW trike let it sit and somehow it would not start so had to use my booster it worked great

rob s.

so far so good,i will give an updated review in a month or 2.im an auto mechanic so i ill put it to good use

William Blake

Jumped off my truck with no problem.

Todd P.

This works in sub-zero weather. I live in Minnesota and had other jump starters that work fine in warm weather not work when the temperatures are freezing out. The reason I bought the GT4000 was it has an internal heater to pre-heat the jump start at sub-zero temperatures and it works great. Additionally to the pre-heater it has never labored in starting anything. Also, it has many outputs and can be used as a power source, and can be charged multiple ways. It came with a vinyl storage back which I didn't like so I bought the optional hard case and it offers great protection. Since my first purchase of this earlier I have purchased 2 more and 2 more cases, one for each vehicle.

Emily Davis

Easy to use. Recharge is real fast. Most important to me is I jump started my BMW 740i without damaging any of the sensors or electronics. Traditional booster cables using a second car is not ideal for jump starting these BMW's. Plus you don't need anyone to help you when your battery goes dead.

Jason D.

I had a lawn tractor and a 35 HP diesel that had been sitting idle for several months. Lawn mower wouldn't even click when the key was turned on. Connected up this jewel and it turned the starter like it was on a full charge. Started after the second attempt. On the big tractor, it initially turned the starter and then just clicked. Connected the GOOLOO and two rotations of the pistons and she fired right up. Absolutely mind blown as to the power this little box has. Definitely a keeper. Understand, this is not a charger but a starter boost to get you running. It will or should turn your motor over with the deadest of dead batteries.

Lily Anderson

Impressed. Jump-started first time and only used 8% of its stored power!

Brian S.

This product is made from high-quality materials, the craftsmanship is excellent, and I have no regrets purchasing this product.

Doug W.

Arrived on time and works great.

Dan D.

The class c camper has parasitic draw. That I just found. I had to jump start the V10 engine a few time already. Works great . Dan

Dan P.

100w fast charge works great, the cold temp function let's me keep it cold and not have to worry

Bernard G.

Excellent service, fast delivery for my new unit. My old one got stolen. But i had problem last summer and i received a excellent service from Gooloo. Recommand them %.

Adelmo M.

Used it a twice, functioned flawlessly

peter j.

I was disappointed because I didn't get my free air pressure gauge as advertised

Christopher U.

I just jumped a car with it that had 2.3volts v6 3.5L without a problem no hesitation and only used 3 percent of the battery. It is well made and after trying other brands that I had to return do to the poor quality this one seems to be very well made.

Mary Johnson

Excellent light weight. Great light and jumps big vehicles with no issue

Antonio C Michael

This Jumper pack is strong love the 100w fast 12v car charger charger with it came with a wall charger though but charges super fast with the 100w car charger have used it 40 plus times no issues I even did a youtube short showing it jump a 2000 4runner and run that 4runner with no battery connected just start and run off tge Jumper pack showed it on a few youtube videos jumping and cranking over a 6.8l v10 with no battery also and it's strong will built love the items it comes with and got a Eva case for it so I'm super happy look forward to grabbed the GT4000s model soon have also compared it against the hulkman alpha 85S and soon against the hulkman Alpha 100 the gooloo is my favorite so far the GT4000 has a few differences then the GT4000s like the GT4000 has a pre heating function for cold weather we're the GT4000S doesn't have that feature but its a good unit all in all super happy with the product and Purchase will be buying more got a little video for you as well.. I belive this is one of the strongest Jumper packs way stronger then noco way more reliable and it goes head to head with the hulkman 85s which it's stronger then but the hulman dosent do 12 liter gas and 10 literally diesel only the hulkman alpha 100 does upwards of 12 liter gas... well built haven't has any issues with it being 100 percent charged and left for 2 years without a charge it does Hold its charge super well for storage and have even jumped a 6.8l gas v10 with only 5 percent charge very impressive Jumper pack for sure

John Smith

This jump starter works great. I love the display feature that lets you know the capacity battery power left.

Marc D.

A really good starter pack and not expensive

James P.

A citizen SUV had absolutely no power. I used the jump starter...nothing! I then tried again using the boost and it fired right on up.

Alexander Peterson

Tested out charging in and output and gooloo performed well. Jumped a few dead batteries successfully. Very useful machine that is compact. I encourage people to get this for safety and convince on the road.

John F.

This charger comes with a cigarette lighter adapter socket. So, no need to buy one separately. The unit comes with an EXCELLENT foam-lined, sturdy box that you can use as the case. No need for a separate case. The cables nest under the charger using the paperboard divider. They even provide a nylon cinch bag for the cables. The unit itself has very good fit and finish, with a nice rubber, tethered cap to keep the cable ports clean when not in use. Very impressed with the quality of this charger. Highly recommend.

Francis Z.

This thing is amazing. After watching a couple different You Tubers testing and comparing others I bought this one. Dead batteries in my diesel truck and this thing will crank it over as if it was just running. as my other jump pack could only produces dim lights and not even a click when I turned key

David F.

A great product. No sparking, reliable, works instantly, as promised.

Todd H.

I bought this products based upon The YouTube Channel "Project Farms", who is a notable, high integrity reviwer/tester of products. This model is alsways in the Top 3 amongst many being tested. I love mine and have used it several times. I wish it came with the case, however. I bought that separate (which is solid and a perfect fit). Looks great, too.

Nav C.

It gets down to -35*C where I live. I store the Gooloo GT4000 in my Ford Escape. In -35*C I jumped my 3.0L V6 Ford Escape 7-8 times and went from 100% battery to 64% battery. I love the preheat feature because I just leave it in the car and don't have to worry about it being too cold to boost like the NAPA one my co-worker has. Co-workers stores his in his toolbox at the heated shop. our shop will only heat up to +5*C when its -35*C, but even thats too cold for his NAPA booster pack to work properly.

Mez

Have needed this a few times. Works everytime so far. Light is useless in low light areas or at night, because it points in the opposite direction of the clamps.

Brian C.

Buy it at a good price and happy with the product. Will recommended.

kyle c.

I love it work awesome I have boosted lots already Can’t wait to see it work in -30/-40

Frank Johnson

Charges quickly and last for repeated starts!!!

Vicki D.

I��ve used this thing from jumping off trucks to firing up my boat motor. Works like a champ

John

I keep this in my car just incase I or someone else needs a jump. My battery started going out and stop start would make my car die at a red light. Good thing I had this in my trunk Luckily I just needed a new battery.

OPHELLO C.

Full featured and worked well for starting and operating a 2.7L, 2000 Toyota Tacoma truck at 50 degrees air temp. with the truck's battery disconnected- as when starting this engine with the Truck's battery connected. And has fast charging capabilities.

Preston

I can't seem to buy extra cables from them. But other than that. It's extremely easy to use and works terrific. It's also very easy to use.

Katarina Anderson

Must have. Easy to use. Can have a dead battery up and running in couple mins. Everything stores in a box ready to go. Stays charged for a LONG period.
