GOOLOO GT4000S Jump Starter 4000 Amp Car Starter 100W Two-Way Fast-Charging Portable Car Battery Charger Booster Pack for 10L Diesel and All Gas Engines, SuperSafe Lithium Jump Box for 12V Vehicles

Great Jump Starter
I saw this reviewed on YouTube from a creator called “Project Farm.” He does some of the best real world test reviews out there. He tested 14 jump starters, including the Gooloo. The Gooloo jump starter came in second place overall and it was just $99. The first place jump starter was $370. An almost 4 times price increase for just a little improvement over the Gooloo jump starter. It arrived well packaged and included a ton of accessories. The Gooloo lets you jump start your car (which was super simple and worked great). But, it also has a built in light with several illumination patterns. I has two USB A output ports for charging your devices. A USB C port for charging the the Gooloo internal battery. The same USB C port can also be used as an output to charge your own device. It charged my video light at an amazing 40 watts (see my photo below of it charging). It also has a DC out port at 15V. There is a female cigarette lighter for the DC out port. However, I think 15 volts is a little high form some devices meant to run at 12 volts. So use caution. There is also a male cigarette lighter with a male USB C plug so you can charge the Gooloo from a standard cigarette lighter socket. There is a USB A to USB C male cord and a double male USB C cord included. This is a very complete package. I charged the Gooloo to 100% and then did a test start on my 4Runner. My 4Runner has an older battery that I am too cheap to replace. I tried to start the car, but it just went, “click, click, click.” So I hooked up the Gooloo jump starter and it fired right up. Not only did it start, it cranked the starter with authority. As Project Farm would say, Very Impressive! The size of the Gooloo is larger then most jump starters. But, that is because it has a massive battery inside which provides the excellent performance. But, it is not too big to be cumbersome. Everything fit nicely into the provided storage bag. The instructions were very clear and simple to understand. Overall, I am super impressed with the Gooloo jump starter.

Good quality, works as advertised!
Works as advertised. On a 2019 ram 1500 Laramie. Battery was absolutely dead. I needed to jump battery one last time so that I was able to go buy a new one and install it at the mechanic. My mechanic couldn’t believe I successfully jumped the bat to get the truck to his shop to install a new battery use it again, and it worked like a charm. Easy to use and has a lot of power to jump a battery in extreme cold weather as I experience.

I use it a lot.
Bought it after watching Project Farm on YouTube. It works great and I’ve used it a lot on my farm. From vehicles to lawnmowers and even my tractor it works good.Another handy use for it is to put it on a dead battery then hit “BOOST” until it beeps then remove it and put your battery charger on it. Most of these new digital battery chargers want to see some voltage on a battery before they’ll work.Handy lightweight simple and powerful. Keep an eye out for a sale if you’re not in a hurry. These GOO-LOO jump packs go on sale pretty often.I’m not putting in keywords for A.I. just so you’ll look at my review but it looks like a couple of them already lit up.Have a great day. 👍

Highly recommended. Easy to use during stressful situations.
Already used it several times. I’m really pleased with how it performs. The big screen with simple large read out is super helpful. They also printed some simple instructions on the back of the unit which came in very handy. Great jump starter. Highly recommended!

تمت تجربتها لأكثر من مرة على سيارة صديق ، كانت ممتازة واشتغلت السيارة بدون مشاكل ولم تسحب من بطارية الباور سوى ٥% في كل إشتراك وأراه معدل نزول جيد.
