The stars speak of…
Opinions about this product were divided in such a proportion among the buyers.
Don’t be fooled by it’s small size compared to conventional jump boxes, this has more power than many four times it weight. Quick to charge, with the convenient screen showing percentage, it’s ready for multiple uses before needing recharge. Removable cables and it’s light weight make it easy to transport from vehicle to vehicle and into the house for charging.
Had an almost completely dead battery on a 5.3L V8. This thing (at 100% charge) would not even crank it. My much smaller NOCO started it on the second try. Also, the clamps on this thing have protective covers around the jaws that make it difficult to attach to side posts. The display is nice, but it doesn’t deliver the cranking amps promised, so what good is it? Not recommended.

Great product
Easy-to-use nice to have backup when car won’t start.

Holds a charge well.
Used this item three times so far, V10, lawn tractor and V8. Didn’t seem to work as well as I wanted. If you hit the boost button 3x forget using this charger till it resets. Just connect it to the battery and wait for a short time then try to start your car. It seems to be all automatic, if your car doesn’t start 3x the unit agains goes to error mode for a time. I hope I never really need this unit or I can figure out how to make work.

Worked on my car
This worked on my Subaru Outback which has been having battery issues lately. Took 2% of the jump pack battery to get my car going so a charge should last a while. Cheaper than other option at the same amp size. I only wish the light had its own button rather than sharing with the power.

Gooloo
The unit will not charge. When you press the power button it only beeps and displays and error E4 message. I have not been able to contact the manufacturer or find a solution for the error.

A Lifesaver for my Mustang GT
I rarely write reviews, but I felt compelled to share my experience with the Gooloo GT4000S. My Mustang GT had been sitting with headlights on through the night, and when I tried to start it, the battery was completely dead. If you’ve ever dealt with a Mustang GT, you know it’s not exactly easy to jump-start the 5L engine. I was skeptical about whether a portable jump starter could handle it, but the GT4000S proved me wrong. It was incredibly easy to use—straightforward instructions, quick setup, and no fuss. When I connected it, I wasn’t expecting much, but to my surprise, the Mustang fired right up as if the battery had never been dead! I honestly couldn’t believe how effortlessly it worked. What impressed me the most was how quickly it charges and how it still had 91% charge even after jump starting my car. It’s not intimidating to use, even for someone who isn’t overly tech-savvy. Plus, the safety features (like spark-proof and reverse polarity protection) gave me peace of mind throughout the process. It’s now a must-have in my trunk. If you’ve ever been stuck with a dead battery, you’ll understand how valuable something like this can be. It’s a great feeling knowing I have a reliable backup. Highly recommend it to anyone!

Most powerful! Best jump-starter!
Absolutely hands down best jump-starter I have used to date!

It’s saved the day many times.
I’ve owned a few different jump starters over the years and this is the best by far. Everybody that sees it in action wants one. Would make a great gift for anybody.

Actually delivers, very stout
I used this a couple of times and it has worked great. This morning I tested it after leaving it in my SUV overnight in 13 deg F (-10 C) weather. I disconnected the truck’s battery altogether, hit the Boost button, connected the jumper cables and the truck (27 year old pathfinder, 3.3L V6) started right up. Afterwards the charge indicator read 97%. Shut it down and did it again without any trouble, again battery totally disconnected. Charge only went down to 95%. Outstanding.

Good!
Like this one better than the one that got stolen-and it was as nice as I could find in a store. Ordering another one.

This is compact but powerful battery booster
I boosted a 5L diesel engine with the booster smaller than a loaf of bread.
