Upgraded GP3000 Jump Starter 3000A Peak Car Starter (Up to 9L Gas or 7L Diesel Engine) 12V Jump Box Auto Lithium Battery Booster SuperSafe Portable Power Pack with USB Quick Charge, Type-C Port

I've owned this thing for a little over a year and its already paid for itself 10x over. My biggest fear when I made the initial purchase was I never heard of this brand and thought it might be one of those things that works great 1 or 2 times then falls apart. That has not been the case yet. My parents recently went from a 2 car household to a 1 car house, and they have just stored that extra car in the garage for the time being. Obviously the battery went low and on 2 or 3 separate occasions this has jump started them on the first shot. Also, I'm a service manager for an HVAC company and we have roughly 20 trucks. There have been another 2 or 3 times when this has bailed us out on trucks with old batteries as well. So all in all within a year I've used this thing maybe 4-6 times and it's worked flawlessly. The battery life on it is GREAT. I've charged it up 2 or 3 different times, but only because "why risk it". Every time I charged it, the battery indicator still showed it had a lot of juice left. Truthfully this thing would probably still be kicking on the initial charge from over a year ago (but again, why risk it). Also, it's so small and compact it doesn't take up any space in your trunk or wherever you decide to keep it. I know there are bigger and more powerful units out there, but I've used this on a few full sized pickup trucks (work trucks) and it's worked like a champ. Also, although I have never used any of the other features other than jumping a car battery, it does have some other things that it can do as well. There is a flashlight on the device and in addition to the standard port where the jumper cable harness plugs into, there are also a few USB ports on there and a USB-C port as well for that you can charge cell phones or other devices off this as well. I've never used anything other than the battery jumper, but I could imagine if you were to ever break down and were stranded, having those USB and USB C ports would really be useful for cell phones. I really have nothing bad to say about this thing. Very much worth the money. My only initial hesitation was the weird brand maybe being a low quality, but in 5 or 6 "real life" uses over the course of maybe 15-16 months this thing has operated with no issues what so ever. Very happy with this purchase. I guess if there were one negative, maybe the charging cable could be a bit longer? But my goodness, that is nitpicking.

We REALLY like our Gooloo Jump Starters. We have one in every car. We have used them multiple times to help people in parking lots who might need a jump. Our daughter is even good at helping out other kids at the high school if they need a jump. She is known as the "Jumper" (she is also a high jumper). These always work. They are just the right size for storage in a vehicle. Not real sure if I prefer the soft case or the hard. I like the look and the protection provided by the hard case, but it does take up more space. I like the fact that you can't mess up attaching them (nice and safe). Ease of mind for me if my children have to use one. Solid build quality. The only issue I have is that looking back I would not mess with the lower amp <3000A units. Not necessarily anything wrong with those, but I prefer the 3000A or higher. With all of the different vehicles we have used them on, the 3000A seems to work great. We initially purchased the different sizes based on the vehicles they were going to be in. And, some of the smaller amp models were a great price. The 2000A works great for our 2006 Honda Cr-V. I tried it on few larger vehicles (larger batteries) and it struggled a little with some of them. Note, the 2000A was NOT recommended for the larger size vehicles. BUT, if getting one, you may want to just step up to a larger size even if it is for a smaller car, because you never know what other size of vehicle you might need to use it on. They were changing the look of the different styles/models for awhile. I have no idea if it was just cosmetic or if there were interior changes. The previous models appeared to be a really good deal for awhile. The problem was, that at that time, there were several models listed on Amazon. At times it was a little difficult to sort the different models out. I ended up going to the Gooloo website and made comparisons there. Then I ordered accordingly. The BIG displays on some models are nice, but they do make those models more expensive. And finally, I unfortunately cannot report on the longevity of the individual units. Sorry. We have had all of them for over a year and they all still work. Most have been almost fully discharged at least once. I check them on a regular basis and have not noticed any natural drain of the units (Kansas hot and cold temperatures).

So I'm not a car expert by any means, but I know a dead battery can ruin your day. I've had to wait for AAA before, and it's not fun. That's why I decided to invest in a portable Jump Starter, and let me tell you, it's worth every penny! I keep mine in the trunk of my car, and it's given me such peace of mind. Knowing that I can jump-start my car myself, without having to wait for roadside assistance or bother a stranger, is a huge relief. The first time I used it, I was a little nervous, but it was surprisingly easy. The instructions are clear, and the smart jumper cables have all sorts of safety features, so I didn't have to worry about messing anything up. My car started right up! I was so impressed that I bought one for my wife's car too. It's just a smart thing to have. And it's not just a jump starter – it's also a portable power bank, a flashlight, and a 12V power supply! It's like a little emergency kit in a box. The build quality is excellent, and it feels really durable. I love that it comes with a storage case to keep everything organized. If you're looking for a reliable and versatile jump starter, I highly recommend the GOOLOO GP3000. It's a small investment that can save you a lot of headaches. Five stars – and I sleep better knowing it's in my car!
