   I recently purchased the GREPRO Jump Starter Power Pack and couldn’t be happier with my decision. This device is a true lifesaver—compact yet incredibly powerful, it has jump-started my car quickly and efficiently on more than one occasion. The build quality is top-notch, and it’s clear that a lot of thought went into ensuring safety and ease of use.

   I also appreciate the extra functionality; the built-in USB ports mean I can charge my phone and other devices on the go, which is incredibly handy during emergencies or while traveling. Its sleek design makes it easy to store in my trunk, and it’s become an essential part of my car’s emergency kit.

   Overall, the GREPRO Jump Starter Power Pack exceeds my expectations in every way. It’s reliable, versatile, and a true peace-of-mind investment for anyone looking for a high-performance jump starter. Highly recommended!

   On the first day I got it I needed it to start my car. It worked great. Just remember if you have a hybrid or electric, don’t keep it in the trunk. Keep it in the glove box so you can have access to it.

   Really like the digital read out on this one and the nice bag it comes with. It has separate compartments for the components. Good Battery Life and hasn’t failed yet. Starts that old electrical nightmare of a Lincoln my pops drives, straight away!

   This car battery jump starter works very well I have two vehicles and one was sitting for awhile most of the summer the weather got colder and my cars battery went dead I purchased this and hooked it up in a matter of minutes my car instantly started it also was mostly charged when I got it in the mail so I didn’t even need to charge it before using it and it’s so easy to use and seems well made now I don’t have to depend on someone having to come help me jump my vehicle and I would definitely purchase this product again

   I used this to jump my mower and it worked flawlessly. Though in my experience if these are not fully charged they will not jump a car well. I did attempt to jump a very dead car with it at 100% and it would only crank a few times and would die. Would be good as a emergency given you keep it charged on the regular

   We have one and it proved to be so handy not to worry about car not starting due to battery. We recommend it to friends and purchased one for my grandson. A friend purchased one and the very next day had to use it. Light weight and easy to use.

   This has saved me 5 times in the last 2 weeks because my battery was weak and then my car wouldn’t start. Be sure to connect the unit to your battery, then press the power button and then press the boost button in until you hear a click noise. Then start your vehicle. I didn’t push the boost button in far enough the first times I tried and then it didn’t work. However, if you press the boost button in until you hear the click, the car starts every time! Charges great with my samsung phone charger also, so its always ready for the next time. Excellent product for a very affordable price!

   The GEPRO 3000A arrived with a 70% charge. I topped it to 100% in about 1/2 an hour. The unit looks like a quality piece, with a nice carrying case and all pieces as advertised.
   Today I had to start my van which had a battery so dead it wouldn’t even click when I turned the key to start. The GREPRO lights indicated I need to use the boost button, which I did twice. The van started but died when I took my foot off the gas. I restarted it and kept the revs up until the battery had enough charge to run the van. I removed the GREPRO, which was down to 74%, and drove the van for about 1/2 an hour. When I attempted to restart, there wasn’t enough charge in the battery to do so. I hooked up the GREPRO and immediately fired up my van. After 3 starts and using boost twice, the GREPRO was down to almost 60%. I recharged back to 100% in less than an hour.
   I can’t speak to the longevity of this unit, but if it holds up over time it’s a big winner!

   Does the job. I was looking for something smaller but they don’t really make jump starters smaller than 2,000A anymore. Wanted something for my motorcycle. Works well once you figure it out. Not as intuitive as my other jump starters. There is a button you have to press on the plug for the battery clamps. Read the instructions!

   As mentioned, its bulky and appears made from cheap plastic but not complaining for the price I paid.

    This 3,000 peak amp cranking unit really packs a punch. This new GREPRO is compact, has one user wire adapter in the kit and a nicely played out storage box. It is very simple to hook up and use. My wife finds it handy too. I even take it with me in my luggage when I travel.

    8 years ago I bought a 1,500 peak cranking GREPRO and it’s still working perfectly.

    I would highly recommend this light weight powerful booster pack.

    Very easy to use make sure that you charge it fully before use!
    

12. T. Mayer Verified Buyer – 21 March 2025

    Have use it serval time on a car and zero turn mower. Wires are a little short and you need to read the instruction if you are trying to jump a dead battery. Work each time no problem.

    I‘ve kept jumper cables in my car for years just in case I needed them, but that meant I had to rely on someone else being around to help me! Since I never know when or where I might have car battery problems, this portable jump starter takes all the worry away. Now I know I won’t be stranded and I can help myself! I can also help others in need, too. I want all my loved ones to have one of these! I keep it fully charged to 100% (the display shows the power level) and know that I have all 3000Amps ready and available for use. It’s easy enough to use, too, just plug the jumper cables into the unit and attach the red and black alligator clips to the positive and negative battery terminals. The jump starter has a light on the end if needed. Since this is essentially a power bank, I can also use it to charge a phone or other device in an emergency. It has ten different protections built in, such as overcharge, overvoltage, short circuit, and reverse polarity protection. A good-quality divided case is provided to keep the unit, its instructions, and the cords organized. Excellent preparedness item to keep in every car!

    The first jumping device with its own power source I ever used. Worked like dream. Great instructions. Great price. Nice storage pouch. Wow!

    I live in a rural area and went without a jump starter for a few months after my other one kicked the bucket. Finally I forced myself to buy a new one to have on hand just in case, and lo and behold I actually had to use it two weeks later. The instructions were easy and my car started right up. As long as it holds up over time (which I know has a lot to do with me remembering to make sure to check the charge on it regularly), I consider it an a+ purchase.
