This gadget is great for taking along with you on the road, particularly the colder the weather gets and the older your battery is. I used it to jump start my riding mower battery which had been sitting longer than I liked. The cables are a tad short but the wires are thick. They included a magnetic end in the battery pack that works pretty well. There is a bright light on the other end which would be useful in a dark area. It is not difficult to operate and it comes with clear instructions. It seems to be made well. The cost seems worth it particularly if you don’t have another car around to jump you. Definitely worth having a portable jumper with you so you can just start back up and be on your way. The hard case is large enough to carry everything whereas the drawstring bag is just large enough to fit the battery itself. There battery takes many hours to charge, particularly on a low power source.

The 4000A Car Jump Starter by Aligoo, is a very useful battery pack with multiple way to be a life saver when the time comes. Here are some of the things I’ve learned while owning it and things to consider before buying.I. Quality – It looks and feels like a solidly built, good quality battery pack, that I’d put in the upper-middle level of the quality scale for jump starters. The ridged protective case is well made as well.II. Performance – It’s on the lower side for peak amps versus what available at only 2000A, but it still works great to start most cars. It claims in the ad to have a 88.8 Wh battery, which is a decent size, making it a wonderful backup battery for devices. The jumper ends have an innovative design that has a secondary wire going to the other side of the clamp for a better connection (see my included photos). The built in LED light is bright enough to be helpful in a dark parking lot. The included case is thick, protective and well-made, providing a great bonus. It lacks a digital display like some of the others I have, but it does have four lights to tell you the level of charge. It also comes with ten safety features to help in overcharging, over temp, short circuit, ext. The cables are pretty short, but they're all short for this type of jumper. I really like the 100W fast charging ability with a nice included cable and the magnet that allows you to mount it easily to anything metal. It's super easy to use and the compact size makes it very portable.Overall, this has been a super helpful, good quality, power bank that can easily be kept in the trunk just in case. With the power to get you going again, this can be a real life saver when the time comes and even doubles as a backup power bank, until that time comes. I’ll be sure to update this review, if I ever start to have problems with it.If you’d find it helpful to see an up-close visual inspection of this product, I recommend you watch my included video in full screen or landscape. They say a picture is worth a 1000 words, well it’s video!You can trust that this review is simply my honest opinion that is attempting to provide you with helpful insight that I wish I had before I picked this product. Hopefully it was helpful in your decision.

This unit seems solid enough, but it is distinctly a Chinese no-name of a so-called "brand" that will likely be here today and gone sooner rather than later.As it happens, I left all of my electronics in my 2005 Mercury Grand Marquis turned on via the unswitched power outlet, which drained the battery to completely dead.This jump starter started up the 8-cylinders immediately. It was actually faster than my fully charged Stanley 1000-amp JumpIt lead acid box.However, the case is light gray, so that is almost guaranteed to easily and quickly, get soiled. And the soft fabric case for the charger is too small to easily take it off and put on.I can give only 3 stars due to the warranty issue, or lack of one. And, without tearing it apart, I cannot trust that it actually has the promised lithium cells. Many generic units like this don't.For $219, I would put that towards a unit that comes with a domestic warranty, and distributed by a company with a business office here, like top-rated Noco.⭐️1 star — I don't recommend it at all, poor quality.⭐️⭐️ 2 stars — I don't recommend it: has multiple faults, or a very high price.⭐️⭐️⭐️ 3 stars — It's passable: it has some faults, but the quality is ok for what it is.⭐️⭐️⭐️⭐️ 4 stars — Product quite acceptable, and it does what it promises.⭐️⭐️⭐️⭐️⭐️ 5 stars — Product that I totally recommend.

Never heard of this brand, but had a previous battery jump starter product before that stopped working for me. I liked how this one was so compact, and decided to give it a try.It comes in a box, of course, and then within that box is a grey zipper case. On the upper portion you have the removable jumper cables as a USB-C to USB-A charging cable. This jump starter came about halfway charged, so I initially left it plugged in overnight to be able to fully charge. There are battery indicator lights that blink as sequentially turn on as more of the battery is charged. Once it was done, all of the lights turned off, however, which I appreciated.The jump starter battery pack itself is pretty hefty, which makes sense considering the battery size. it appears to be well built. There is a button to activate a light, and then there is a separate power button. There are rubber "caps" I'll call them that you have to pull open to attach the jumper cables or there is another one on the opposite side to plug in the USB charger. The actual battery pack also comes in a little synch grey baggie. That's kinda nice too, but it is one more thing you have to open up. Considering the whole thing comes in a grey hard case, I'm not sure the little baggie is required. Maybe it's there to help protect it, but the grey case has a flap between the upper portion and the bottom portion.As far as actual usage, it does what I needed it to do. We've had a few problems with a 2016 Kia Sedona's battery, and have had to jump start it. This thing brought it to life in no time at all. Just hooked it up to the battery, powered it on, and we were in business. I also have a 2013 Kia Forte that we've had to try it on once as well. No issues whatsoever.At $219, this is pricey. At the time of this review, there is a coupon as well, which is nice. I do think it is a little on the pricier side, as I've gotten similar products for less in the past. although they were significantly larger.

I think at the Baseline for how expensive this is they could definitely bring the price down some but when they do their sales and they have coupons that are like 40% off and stuff like that it is 100% worth it. It charges up quickly the charge last a great amount of time and it definitely has enough power to jump cars. My husband owns a car lot / mechanic shop and I got this for him so some of the guys that work there can bring it around and make sure all the cars are starting and jump cars if they have been sitting for a while and whatnot. This is easily able to jump quite a few cars before the juice runs out. Super heavy duty very durable and well made and not super cheap or easily breakable. It came well packed and secured and everything was exactly as described in the ad. Very easy to hook up and use and very easy to take off and bring it wherever you need it to be. Overall I feel like they could bulk it up a little bit more and make a even bigger battery and a little more power for this price point but with the 40% off coupon you really can't beat it. We are very happy with this overall and this would also be great for your emergency car kit. Still a solid 9 out of 10 in my opinion and we are very happy with this. Definitely worth the money in our opinion everything functions as intended and it will easily jump the cars. It's the perfect size to be portable as well and it's not nearly as bulky as the big jump boxes that they have. Very impressed

I recently got this Jump starter, and I'm impressed with its performance. It easily jump-started my BMW 528i, even without needing another vehicle. The battery pack feels solid and well-built, and it comes in a durable hard case with a smaller grey bag for extra protection. I appreciate the clear battery indicator lights and the separate power button. The 100W quick charge feature is great for powering up my mobile devices and tablets while on the go. That said, it’s a bit on the expensive side compared to similar products, though it’s more compact and portable. Overall, it's a great investment if you want something reliable for emergencies.

I purchased this because I thought it would be much easier than trying to give someone a jump than using my Hybrid. It has not disappointed. It is made well and the instructions are pretty clear and easy to follow, The bonus was it also works as an incredible power bank for giving a quick charge to the phone. Very happy with it.

I needed something to have around after my mother's car battery died a couple times this past winter, I couldn't get next to her car to jump it and had to push her car out of a space to get it started. This holds a good charge, started her Kia right up, and is small and compact, you can charge you phone and stuff with it too if you needed to in an emergency
