We borrowed a friends Gooloo Jump Starter 2-3 months ago after having problems with our 4wd crank battery. It was really easy to use and quick, so we could get on the road immediately. As we travel a lot we decided to purchase our own, and have twice used it since. Thanks Gooloo, a great product and we loved the discounted price as well.
Kristen E.
So far, seems good. Haven't used it to jump a car as of yet.

I borrowed my son`s when we recently had a blackout and I charged my phone with it. I was so impressed, I bought one for another son for his Christmas gift, so it has not been used yet. I was going to buy one for myself but will have to wait until after Christmas to get mine

As mentioned in previous answer, waiting on answer of in car charger purchase
Beverley H.
Did not have any success using it to run my 15litre engel fridge because when the fridge cycles off the unit shuts down and doesn't come back on when the fridge cycles back on.
A bit disappointing.
Neil D.
Good feedback and fast delivery!
Glenn F.
Excellent communication and good product. Easy to deal with.
Kristy L.
Fast service and such a great little unit.

Review your mailing and inventory systems.

I was quite impressed. I have twin 6.2 litre Ford Leehman diesel with turbo's to make sure them 6.5 's and I've searched high and low to find jump starters for under 250 so when I saw these I was more than impressed considering every other jump starter price stated at $230:00 and that is when they were on special. Anyway I'm hoping they will start the motor and or motor's wherever necessary!
I'll write an update soon once I've fully charged the item.
Phil B.
Haven't had the need to use it yet. But it appears to be sturdy, well constructed with quality materials and is very well packaged.
Bought on the recommendation of others who have and were impressed.
John D.
Arrived well package in reasonable time. Charged to full quickly. Works with my IVECO 70 series when my old unit wouldn’t. Jump start from Suzuki didn’t work either - this one did!!
George M.
Compact and solid unit. I have not used it yet on any car, but I have used it in my motor bike.

Clif C.
As described, arrived within time frame
Eddie H.
Havnt had to use it as yet, so hence the 4 stars, bought for peace of mind whilst driving old classic. A hint for those who do purchase, I have set a reminder on my phone to recharge every 3 months as per manufacturer's instructions.
Allan Y.
Great product; light weight, compact (fits easily in my motorcycle panier), the sturdy case means I'm never worried about it getting damaged. excellent price too!
Wayne S.
I haven’t used my new jump starter as yet. I don’t have to. But I do like the compact design and the great packaging/storage pouch. It fits unobtrusively in the corner of the boot.
Barry T.
Bought for my wife for her birthday, she was very pleased with it
Andrew B.
The jumpstarter is as advertised. Impressed with the kit that is included. Communication, once purchased, to track the product could have been better.
Neil B.
Very happy with my new jump starter
Steve C.
Great service. Great product.
Robert B.
Fast and efficient service plus delivery.

Haven't used it yet to start a car. Only topped up a mobile phone 4 times from 75% and it's gone done 25%
Hope it performs if and when it's needed.
Alun B.
As a full time mechanic I'm always having to jump start cars my jump pack has started every thing from 7.0 litre diesels down awesome piece of equipment never gp anywhere without it
Allan W.
I ordered mu Gooloo on a Saturday Morning, it arrived 3 days later (brilliant) and you wouldn't believe it my Diesel Jeep Grand Cherokee had a flat battery on the following Saturday. Brought out the Gooloo and hooked it up and turned the key and instant start, thank you Gooloo.
This would be the best piece of gear that I have ever purchased. I am about to take off on a 3 month traveling holiday towing my AVan Cruiseliner and my Gooloo gives me a nice warm fuzzy feeling should I experience a flat car battery while caping off-grid. Thank You Gooloo.
Paul D.
Definitely overkill for 3Lt vehicle but certainly brings a dead battery back to life. Excellent product.
john b.
Have not needed to use it yet but looks well made so happy so far
Bob
Simply amazing.Started this truck on the first try with a dead battery. I am impressed. Quick hook up and gave me two minutes of crank time. The device had also been sitting in the cold for three months prior to operation.
Isabella Morris
I bought the GooLoo 4000 in early summer of 2023 and haven't really needed it as a jump pack until February 2024 to start my Ram 2500 V10 Magnum. The ignition switch is a bit worn on the truck and it had stayed on and drained the battery dead as a doornail. My GooLoo hadn't been charged since summertime, but it showed that it was still fully charged. I hooked it up to the truck's battery and pressed the boost button. I turned the key on the truck, and the 8.0 V10 fired right up. The GooLoo 4000 does everything I needed it to do and I am 100% satisfied.
Geoff S.
Just what I needed
Ethan Anderson
Tried two different times to jump start a vehicle did not do it I just use it now to charge phone and I-pad
Eric W.
I spent more to get a high capacity and glad I did. After charing up which tool a few hours it easily started this Lull machine several times and it still does need to be charged. I highly recommend this and also plan on getting one to keep in my car!
Philip Howard
A must have for running a farm
DIANNE O.
Extremely happy with the purchase very solid and works beautifully highly recommend
Brent F.
I just got this so I haven't had a chance to use it yet. I'm mainly just adding pictures at the moment. I will update this review later on with my experience with it when I do use it. So far though, the build quality seems decent and It comes with a nice case that should help keep it protected in the trunk.
Ron Ramblin
These things are such a lifesaver. Just the peace of mind having it in my vehicle while it's parked at the airport for a week is worth the price. I have a couple of these & this one is about 30° larger but with more than twice the starting current & 4x the peak current. The leads are nice & long so I don't have to leave it dangling off a motorcycle while boosting. The clamps are large & easy to get a grip but the metal that actually goes on the terminals is tucked way inside the plastic so they are very hard to put directly on a battery with side terminals.This booster hasn't failed to start anything I have put it on. I did notice that it got pretty hot after a while. It also takes a long time to charge.The storage bag for this booster is very simple & large & that is a main reason that this booster has become my go-to when I know I am going to need to use it. The bag does not have any protection, though, like some of these sets. It also doesn't come with any accessories like a 12v car cigarette lighter adapter though it does have a port for one.These are great little power sources for charging or running small electronics. I was able to power my portable satellite radio & a usb speaker on a picnick table on a camping trip. This has my favorite USB-C for charging & output. It also has 2 USB outputs, 1 is regular 5v & the other can go up to 12v but I don't have anything that requires that. I have noticed that some smaller devices won't charge off the USB or USB-C ports presumably because they don't pull enough amps to be detected by the device. I really haven't used the light much because it is it isn't particularly bright, faces 1 direction & isn't particularly easy to switch on. A lantern style light with a dedicated switch would be better.
Mark
3 batteries semi was dead enough the lights were off, magically it jumped it, cables got hot but it worked, so impressed, I've had mine for almost 2 years
KERRY D.
Great service received parcel earlier than expected...great value
Lesley F.
Very happy with jump starter very good quality ! Had some issues with delivery notifications which were very promptly dealt with after an email to Gooloo ! Would definitely recommend you to anyone.
James Lee
As an automotive technician I have used plenty of jumper packs, this one is by far the best of them all to jump dead batteries. The conventional jumper packs I have takes two to jump dead diesel batteries, you only need one GOOLOO 4000 to jump a dead diesel batteries. A little over a year my GOOLOO jumper pack internal battery swallowed up and failed. I contacted customer service and talk to Fiona gave a few details of what went wrong and with no hesitation they sent me a replacement one. Outstanding customer service! Thank you so much Fiona for your help from a pround owner of three GOOLOO 4000
Bill A
This portable battery is a vital part of the things you need to keep in your car.This battery can start your car if you break down anywhere. It carries a full charge strong enough to start any car. It��s easy to use and comes with attachments that can clip right to the battery just like jumper cables. It does take a full day to fully charge.But this is something you don��t want to be without. This is going to be as important as a spare tire in your trunk.The clever design also includes connections for USB. So if you wanted to you could charge your phone at an event where you can��t find an Electrical outlet. Highly recommended.
Emilia Jones
Worked as advertised, my car started right up
Norm T.
the unit is big enough for mid range vehicles. Have no problem with jumping the diesel John Deere tractor. All good !
Marina S.
Good product, great price.
Richard H.
You get free airpump with it now where's mine only purchased a couple weeks ago
A Paul M.
This thing did a great job but recently no longer charges. If its been off charger and I hit the power button it turns on but wont jump anything and wont charge now. For the 125 I paid for it, it should've lasted longer.Bought it May of 2023 and probably used it 10 times. ???? wish it had longer leads too.
UPDATE: Im upgrading my review to 4 stars for awesome customer service! GOOLOO reached out to me and sent me a brand new jump box kit. I thought I was stuck since I bought it back in May of last year but they have an 18month warrantee, which of course I didn't read. Kudos to companies that still take care of their customers. I am a happy man! Will advise long term on this bad boy.
Erik H.
I’ve used it a few times…work great. Has plenty of juice to jump most vehicles.
Charles H.
My friend call me that the truck cannot start the engine because of battery died, he rented for moving the his house. Probably they didn’t turnoff some light.
The 30’ truck engine started with the jump starter very easy.
I just surprised that I haven’t used it recently and not charged recently maybe like a year.

Whata great little tool, love it. Will certainly recommend gooloo to all my friends, well done

Good product. Delivered as promised

I purchased this model for my brother and decided to get one for myself. I was hospitalized and that caused my car batteries to all die. It worked great in my Dodge Magnum with a 5.7 Liter V8 engine with a nearly drained battery. The battery was so low that the car didn't give it an adequate charge even after 20+ miles. I ended up pulling the battery out and charge it externally. On my Lincoln, the charger started it no problem but a Lincoln will be a Lincoln and the car was in the repair shop for over a month. This killed the battery again and permanently damaged one cell. The safety of this jump starter combined with the slightly charged but damaged battery made it nearly impossible to start. The safety kept disconnecting despite me pushing the button. The only was was to completely disconnect the existing battery for the jump starter to not shut off when the bypass button was pressed.
As I said, it's a good feature as someone's that I know didn't have these safety features and caught on fire when he didn't disconnect it while driving after the car started.
Bob
I haven't had to use it yet but it charged up quickly and is holding the charge.
Dylan
I've been in the car business for 34 years and used a lot of jump starters. Gooloo is hands down the best. They're reasonably priced, powerful, and reliable.
Handsome
I was very skeptical about the power of this jump box. Description said it would work on diesels. I'm AMAZED. It easily started my 6.0 power stroke, and my 310A JD backhoe! Highly recommend this product. Nice case, small size, easy to use, great price. What's not to like?
Valerie S.
Has the power to jump star the vehicle I can tell the difference from other jumpers in the past this one is powerfull. You get what you pay for is true.
Wise
I would argue that this product pays for itself the moment it bails you out of a tough situation
Michael F.
I purchased the 2000 series over a year ago and it has come in very handy and ready to go on 2 occasions. So happy with my first unit I decided to buy the 4000 series for my son for Christmas. That way he will be able to enjoy the benefits directly for himself and also he can be useful to others in need of a quick jumpstart. Best handy backup product ever.
Mike L.
Good product - nice and solid and case is protective. Haven’t used it yet so can only comment on appearance.
Tina
It melted when trying to jump a Truck
John T.
I ordered the product and I got it within days. The service was excellent. Really happy with them. Thank you
John.H
I bought this based on a comparison review I saw on YouTube by Project Farm. There were units that cost more but the performance in his rigorous testing was fairly equal. I've used it a few times now since I bought it last November because my work truck has a parasitic draw that pulls the battery down if it sits a few days. This booster is twice as big and heavy as the old one I had before and turns the engine twice as fast and still has over 90% remaining power after a boost that would completely deplete my old one.
It also comes with a really nice tough shell carry case and accessories that will let you plug a cigarette lighter plug into it. It will easily power my 20 watt GMRS radio and can be used to charge your phone in an emergency. It's awesome, I recommend it.
Sandy
This unit does not hold charge for long
Only 2.. 4 cylinder gas cars were used and it sat for 4 days not used, it was fully charged before.
Now it's totally dead with the charge indicator light blinks constantly with no power
I have contacted the company, with no replies as yet
Andrew J.
Nice and compact with plenty of grunt
James T.
The product was delivered in a timely manner and in perfect condition
Dariush
This little dandy will jump your car, has a flashlight, will power your phone as well charge it, might do other stuff too, haven't checked it out too much yet
Ken
Just when you don't think you need something like this...you need it. We have used this numerous times and when my daughter travels, she takes it with her. It's extremely handy and can be used for many things. We also use it during bad storms and it's never not worked properly. It's a great buy!
Colin B.
Howdy, ive had this for 8 months. It stopped charging/holding a charge. I contacted their customer support via email but they have not responded. So im stuck with a dead battery unit.
Robert K.
Followed call D. instructions, charged it up correctly put the clamp on my battery correctly and car just cranked and then tried the boost option and again nothing. by this time my wife had come home and I use my cables and connected it to her car and my car started immediately. Perhaps I just got a defective piece of equipment. But I requested my money back, I’m gonna have to go through the inconvenience of returning the first one. I’m sure not not gonna gamble on this and have to do it again for the second one. Going to Look at some other brands.
Ora O.
Started a VW diesel car with a bad battery just fine.

I like the size and the power it packs. Jumped my car with ease.

Item received with a week of ordering, looks like great quality. I haven’t yet had to use it but am confident it’ll get the job done when required.

Haven't had to use it yet, however the delivery and customer service was great
zane
This jump pack is excellent. Easy to use with a nice case. Has excellent jumping capacity. On a single charge have been able to jump start a 6L V8 3 times and a 3.6L V6 that uses a 900amp CCA battery and only used one bar of the pack. Really good jumping power and would recommend.
gordon t.
I love it won��t see me standing around stuck, waiting for a good citizen to give me a jump

Michael S.
Works exactly as wanted. Unlike other products, I was able to start a car with a completely dead battery. First try. No waiting around for the car battery to charge up a bit. It could not be better.
Joseph W.
I bought this only used it maybe four times because you know how often do you jump a car... The charging port is completely wrecked .. the internal piece of the port has metal exposed and doesn't allow for connection to the charging cable so the whole thing is garbage completely useless if u can't charge it and of course thirty day window is closed
.. but the thing wore out with just regular use after only a few charges ...I'm very disappointed especially since I live in the country alone and don't have a job and can't afford to replace this and am now stuck with a dead battery in my car and 200$ wasted on this poorly made garbageb
Kevin L.
My brother had one which I had to use and it was a simple plug and play. Had to buy myself one.
Ray S.
I bought a Gooloo for my car last year and everyone keeps taking it - for work to start the trucks or excavators, at home to start the mower or when camping to charge their phones or use the torch... So I bought them all one for Xmas (and a pretty purple one for me so they know not to touch it!) - Perfect Young & Old Adult gift idea.

I purposely drained my car battery down to about 9 volts to the point the ignition didn't even click.
I hooked this up, according to instructions (important) and my 4.2 liter engine fired up as if I had a brand new battery connected!
Truly amazing!
People here have complained about it not having a wall wort (wall charger) and I have to say that by now, most people have them for their phones, tablets and a slew of other things common in most every house. I think a lot of new phones don't come with them any more. How many does one need? I think I probably have a dozen of them by now.
I would suggest however, that if you need to purchase one, get a name brand one of good reputation! Having good circuitry there assures safety and reliability.
The GooLoo GP4000 is rated tops on line. Even above similar jump boxes costing more than twice as much.
I now have peace of mind in my trunk!

Bought to keep in the truck for emergency's and to jump off my tractor (I haven't got to do that yet) but I did come to the aid of a gentlemen that was stranded in a grocery store parking lot. There is a button on the cable attachment labeled (Boost) Press that and wait about 20 seconds then have the person turn over the engine and it fired right up! I got it at a Prime Member Discount Price and it's well worth the money.
