Customer Ratings & Reviews

Everything works as listed and I love the idea of never being without power in my vehicle!

Easy to use, easy to hook up. Fastest battery jump ever! So easy, even a Fifth grader could do it!

The Gooloo 4000s was recommended for my granddaughter car Kia Forte GT. Bought because she will be leaving it in storage for a couple of months, needing a jump when she takes it out of storage.

This unit is "quality" throughout. I'm very impressed by its features. Very simple to use. Online owner's manual is very clear and complete. I would definitely buy from Gooloo again.

I didn't realize how handy it would be to have a tool like this GooLoo GT4000S, I've used this 3 times now and it definitely has the power to easily jump start my F150 V8, thx alot, Mike

GooLoo GT4000s is a wonderful, easy to use battery jumper. Very pleased with how great it works. I bought 2 of them !

I have been wanting a jump starter for a while now to make it easier when needing to jump cars and mowers. I watched a lot of videos on Youtube and this one always finished near the top. It seems well built with a lot of accessories so I hope it last.

Haven't jumped anything but we have tried it out to charge phones and power a large laptop. Lots of power available! The unit is even more ruggedly constructed than I expected!

I like that the GOOLOO COMES 75 percent charged.. So You can use it immediately. Thank You!

Too late for video's. I bought this for my pball friend that lives out of his Pilot SUV. I can tell you this. He loves it and I knew he would.

Battery pack works good. Haven't needed to use the jump starter. Fast and easy ordering experience.

Project Farm never gets it wrong. You can thank that YouTube channel for the sale. I use the device all the time. Great product.

Excellent product. The quality is top notch, and shipping was really fast. Well packaged also. A perfect transaction and am totally happy with my purchase. thank you.

I jumpstarted a huge diesel truck today. I had the leads connected and-vrooom!-it roared to life. Everyone was surprised

This is the 3rd GOOLOO jump starter I have purchased. I now have one in each of my vehicles. I have used them to start 2 friend's pickups and the the jump starters have worked very well. I am impressed that such a small battery can start a vehicle. Now I don't have to worry about carrying long jumper cables and jockeying to get two cars close enough for a jump start. And I don't have to find another vehicle to provide a jump. I have AAA that will provide a jump....but with this jump starter, I'll be on my way without waiting for an AAA service truck.

Showed up just in time. I used it the next day. With out it I'd been stuck in town in the snowy cold.

Gave to a friend, that were are doing off roading in the spring. He was thrilled to have it & I shared with him that I've used the product and others like it for many years. Always find them completely dependable.

Great Battery jump starter and lives up to a number of review indicating it one of the best. The mini-blower is awesome .... All I can say is WOW to both. Most like the best purchase of the year.

I didn't even have it for a week , charged it and my next door neighbor called and her Nissan Altima battery was dead. She said she got two jumps but no one could start it. I hook a the GooLoo and it fired right up . Didn't even hardly use any power. Paid for itself already. Thanks

I bought this after a friendly stranger used one to jump my car. It seemed like a good solution since AAA can take anywhere from 10 minutes to 45 minutes. I used it for the first time a few days ago--my battery is often dead if I don't drive it for a few days (thank you, winter!)--and it worked like a charm. This is coming from someone who knows absolutely nothing about cars. Super easy to use, immediate success, and peace of mind. Love it. The only thing I would say is that it takes a really long time to charge (I don't have the fast charger). But it was 65% charged when it arrived, so that was nice. Five stars!
