I’ve read numerous reviews about this type of jump starter, and I must say I’m impressed. I successfully started a Nissan Patrol diesel that had been sitting idle for quite some time. While it may not be suitable for constant use, it works perfectly for three to four starts without needing a recharge. Plus, when it’s not in use, it doubles as a power bank, which can really save the day. The case, cables, and other components seem to be of good quality, and it’s not too bulky to keep in the car at all times.

I’ve used this product 5 to 6 times over the past two months, and it has performed flawlessly every time. It worked well on my 4-cylinder 1.8-liter Mercedes Benz sedan and my 8-cylinder 4.8-liter Lexus SUV.

This jump starter has been a dependable and consistently effective tool for starting gasoline engines with 4 and 6 cylinders. Keep in mind that the 1500 Amp rating is a peak measurement under optimal conditions with the boost feature activated. The standard jumpstart current is 300 amps, which represents its typical operating capacity. It’s suitable for small to medium-sized gasoline engines and can handle larger engines under less demanding conditions (like a weak but not completely dead battery) by allowing several seconds to charge or using the boost feature if necessary.
It’s important to remember that this device contains a 10,000 mAh battery. When fully charged, it can jump-start a dead battery about three times. To maximize effectiveness, aim to charge it fully every 2-3 months and after each use.
There’s always a risk of receiving a defective unit, so it’s wise to test it beforehand. First, drain the battery by charging other devices via USB and ensure the charging capacity aligns with a 10,000 mAh battery; it should only warm up slightly—if it gets hot, there may be an issue. Next, recharge it to full capacity, then connect it to your car and confirm that the lights on the battery clamp module are functioning (they should be a steady green for a healthy car battery). If those tests are successful, your unit is likely in good working order, and I believe you’ll have an excellent experience with it, just as I have.

This is a must-have for your car. It eliminates the need to depend on others when you’re in a tight spot. It’s lightweight and fits easily in the trunk. I already own two NOCO Boost gb40s but decided to give this one a try since it was on sale. I’m glad I did—it performs just as well. I’ll provide an update if its quality and durability don’t match the NOCO Boost gb40.

This product is lightweight yet works flawlessly! I’ve used it twice to jump-start my car, and it worked instantly each time. I also appreciate the added safety features. It’s very user-friendly.

We have an older 2009 Mercury Milan that we use as a spare car, and we’ve been having issues with the battery draining if it’s not started every 3-4 days. When that happens, we have to jump-start it with another vehicle and jumper cables. I’ve been wanting a jump starter pack for some time, so I decided to try this one due to its affordable price. It exceeded my expectations. It arrived well-packaged and is compact enough to fit anywhere. The instructions were straightforward and easy to follow. After charging it at home, I took it out to test it, and it worked on the first attempt! It’s so much more convenient than having to position another vehicle to connect jumper cables, saving both time and hassle. I can’t speak to how it would perform on larger vehicles, as I used it on a smaller 4-cylinder car, but it worked perfectly for my needs. I highly recommend it if you’re looking for an affordable alternative to more expensive jump starter packs.

When my wife’s car wouldn’t start, I needed a solution to determine if the problem was the battery or alternator. I ordered this product for same-day delivery so I could test her car while she took my truck to work. After fully charging it, I connected it to her car, and it started immediately. This is an excellent product that I plan to keep in her car for quick and easy jumpstarts in the future!

I’ve used this product three times now, and I’m impressed with how quickly it works, even with a completely dead battery. It’s user-friendly and safe; my 14-year-old son had no issues using it. It comes with a small, lightweight tote bag, making it easy to carry anywhere. The built-in flashlight has a bright strobe mode, which is a nice feature. It includes a USB charger, and I recharge it after each use before placing it back in the bag. The recharge time is quick as well. I drive a Jeep Wrangler, and I was pleasantly surprised by its effectiveness. I recently got a new battery for my Jeep, but now I feel secure knowing I can handle any future issues myself. No more needing to ask for help! 👍 10/10

I’m extremely pleased with this jump starter. The “boost” feature allows you to jump-start a completely dead battery, which helped me start my car without any issues. I own a higher-amp starter, but this one quickly revived my dead Miata without hesitation.
The charger arrived nearly fully charged and took just an hour to reach 100%. The flashlight function is effective, and everything fits neatly in the included pouch. It’s compact and won’t take up much space in your trunk, giving me peace of mind about its performance. The clips are sturdy, and the overall quality feels impressive, especially considering the affordable price.

Great instant booster!

I am thoroughly impressed with this product! The charging time is incredibly short, and it’s super easy to use. After charging it, I tested it on my 20-year-old double battery Ram diesel, which usually requires two other diesel trucks to jump start. It worked IMMEDIATELY! It’s small, lightweight, compact, and easy to store. I’m considering getting one for each of my six vehicles—two Suburbans, an F350, and two imports—so we won’t have to rely on strangers for a jump or wait for AAA service. The price is also very reasonable. I plan to try it on my farm tractor, which is another double battery diesel and even harder to jump than the trucks. I’ll update with the results. By the way, this is my first Amazon review, and I felt it was important to share my experience!
