bought this as a precaution for future problems, if it works as well as my first one, I'm sure I'll like it
Nick Z.
Very happy with the GT4000, quality product

Takes less space than jumper cables and you don't need another car to supply the boost. Faster, easier, doesn't require the assistance of a stranger to use.

Didn't want one of those big bulky jump starters sitting in my semi, so I landed on the gooloo. Big power in a small package. Refrigerated trailer sat for over a week in 10 degree weather and drained the battery. Took a couple cranks to start, but only used 4% of the charge. Took an hour to charge with my vehicle before I bought this, so I'm happy with my purchase.

The first item arrived and didn't work. I immediately contacted the folks at GooLoo and received a second, fully functional battery booster within days.
Robert F.
better than expected!
Becca B.
This battery is GREAT! Exactly what I was looking for.

Traveling from MI to MT dozens of times over the years my first unit offered comfort just knowing it was with me. Most recently my brother-in-law, planing a hunting trip to SD, i gave it to him. So now I have another. Best insurance policy I’ve never needed.
Earl K.
Works good surpriseed how much creaking power it has.
Luis F M.
Worked great, actually helped someone else get their car started like 2h ago.
Cleo B.
It was better than the last one i bought from you and that one lasted for 5 years under constance use.
Vance M.
Bought this one because I was so impressed with the the model without readout and pre heater.
As with previous model, more than expected. 2 trucks 2 chargers... Right?. Then 2 inflators for the same reason. They even sent me a sweat shirt

Great battery jumper!!

I did not know that the charger was not included. The description should be clearly stated that charger is extra. I also disappointed that no carry case with the charger.
Bryan B.
Very nice and quick shipping.
Cameron M.
Love the product. I'm a believer!
Nicholas B.
Awesome product, gonna get another one soon!
Will S.
A week after buying it, my car wouldn't start in the cold morning after camping. My friends had already left and without the Jumper I would have been screwed
Martin P.
Very nice unit and very easy to use!
Robert L.
Amazingly effective and compact device; fits in glove box.

Haven’t used it yet.

Was very disappointed that they show a picture with a 100 watt charger a hard case and a free gift, but did not get any of it.. but love the jump starter
Brian G.
This unit is amazing. Very rugged and high quality! I ordered it based on the unbiased and highly independent review from Project Farm! It performs really well.
Donald C.
Works great , fast shipping
Eduardo L.
High quality product, fast delivery I would recommend it.. thanks
Lawrence G.
Proper equipment for the Proper job

Haven’t got to use it yet
Matt D.
Very compact - nice display - 100w fast charging - used once and still charged at 93%
Curt R.
Came as expected. Bought for piece of mind over older unit. Like the compact design. Used to jump a 3.3 v6 sitting in garage. And have used it as a cell charger. Since I live in a cold climate I'm hoping this model with the heat tech will come in handy during any emergencies but haven't tested that feature yet.
Don M.
It does everything I wanted and more
I saw it used on YouTube channel from Chickanic in Arkansas
Ben B.
I ordered the total package (jumper, fast charger, carry case) and only received the fast charging block.
It took longer than I believe it should have, but they did make it right in the end and resent everything that was missing.
I’ve used it a few times now. It came in time to jump my little Nissan car and my diesel pickup. I don’t drive them often and have to charge the batteries. I use a work provided vehicle 90% over the time.
Both barely cranked and the jumper did its job with ease. Although, I feel like the charge may not last as long as they lead on, it was definitely worth every penny so far.

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.
Sheronda D.
Glad to have this. It��s very easy to use & once connected to your battery, the car starts right up!
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.
Ken G.
Seems like a very nice unit, nice cables and accessories. I haven't needed to use it yet.
Sterry A.
I just love this GooLoo jump starter. It is light in weight and very easy to use. There is a number of applications you can use this for and not just jumping a vehicle. I really didn't know about this product. I watch the YouTube channel Everything Autos and Jeff was showing this product on one of his videos. With the Christmas Specials that GooLoo had going on I couldn't resist. What a smart investment. This product is so easy my wife can use it. That was the main reason I bought it. Thank you
Adelmo M.
Used it a twice, functioned flawlessly
Bruce F.
I only received the carry case and had to contact customer service. They eventually got the charger sent as well. They are very helpful and made sure I got the balance of my order.
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
Dylan S.
Bought because of Project Farm videos.
JOHN M.
The product is exactly as described. My son will be taking it to North Dakota in case he ever needs it. We charged it up with a laptop charger and the feedback on the big display is great. I am glad I have this display instead of just status lights. It seems like the display will make it very easy to use when you really need it. The included cables all seem to be well made. If there was a padded case option for just the power unit, I would buy it. The product included one draw string case for everything but I want a little more protection just because this unit is no nice.
Brent K.
Although I have not used it for jump starting yet I have used it to charge my phone and it works fine for that. I received the unit and was impressed with the accessories along with the box it came in but would of preferred that their storage case for this model had been included, especially at that price. It looks and feels well made. I like the bright LED light the big display for showing the state of charge and the charging voltage. Those features along with the Specs and all the positive reviews were the main factors in my decision to purchase the GooLoo GT4000. I purchased it direct from their website that just happened to be running a sale along with free shipping. I am glad I didn't wait to pull the trigger because last time I checked they were sold out of that model. Only time will tell but if everything functions as it should and the battery lasts for many years I will be more than pleased with my purchase.
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.
James C.
Nice and heavy construction. Great build quality. Has everything most other brands and models don't. Mine is an updated version just sent late Oct 2023, and charges at 120watts from the factory set 80% charge. Temps have not gotten below 19°F so I have yet to test heating capability.
RICHARD D.
I find that it’s well built - easy to understand and operate - a lot better than carrying long jumper cables and to keep in my truck
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.
Jeff G.
I left a four day music festival today, and I started a truck and a car for other people. They had completely dead batteries, and my starter went from 100% charge down to 95%. I probably sold five of these chargers today, Everyone was impressed with it.
Tammy M.
Works great, arrived quickly
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
Morris A.
Good value and outstanding job
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.
