Update 10/9/2024: Went to plug this in and as of October 1, 2024, the battery will no longer hold a charge. I bought this on March 11, 2018, so I definitely feel as of I got my money's worth out of it though. Update 12/30/2022: I still have this. It's not something I use often. In fact, during the pandemic, I went an entire year and a half without ever needing it, but still religiously charged it at least 1x a month even when not in use. For reference, it was purchased on March 11, 2018, and on Friday, December 30, 2022, I had to jump a individual's SUV, because his battery died while in my driveway. This did the job with no problem and is still recommended. I'm actually very impressed with the quality and how long-lasting this is. Got this and immediately charged it as instructed. Was a little worried due to reading reviews that some had received this DOA or that the jumper never fully charges. I did not have that problem and I've since used it twice to jumpstart my car battery this winter. Very convenient and safe to have on hand in those emergency situations (for reference, I jumped a little Kia Rio sedan without problem). The portable jumper was charged immediately after each use and will be every 30 days per the instructions, so I hope this lasts. Am thinking about purchasing another one as the price was WAY cheaper than in a certain auto store with "zone" in its name... I'm giving it 5 stars since it has, now twice, jumped one of my cars and I have experienced no issue with the device failing to fully charge. The air compressor, light and ability to charge your USB devices are a plus as well, but I did not purchase it for those features. It performing as expected, the price, amps and portability were the main factors.

Every since I bought this item I was only able to utilize it 3x, afterwards the inside battery dosent stay charge, so therefore I can't jump start my car if needed. Ive charged it numerous times at work from 630am- 1pm and it still dnt fully charge 🤬🤬🤬. I asked a mechanic at work what could be the issue, and was informed that the battery within is not good since it dosent stay fully charged. This item needs to be sent back or replace. Im always frustrated during winter!!!

I bought this because my car was having battery problems, and I figured this would be good to have as a backup. Sad to say I was pretty disappointed right out of the box in that my didn't even come with a charging cable of any kind. Anyway, so a few weeks after getting the unit I find my car battery has died. So, I follow the instructions and pretty easily jump start my car. Awesome! Fast forward another week or so, and I end up needed to jump my car again. Again, it goes smoothly. When I got home I checked the battery, and noticed the indicator light was low, so I brought it inside and tried to find a way to charge it. Lucky for me I had a couple 12 volt chargers laying around (because this didn't come with one). I plug it in, and the light comes on which I assume means it's charging? Well, it seems no matter how long I leave this thing plugged in, it will not charge even a little bit. The light always says it's low, and that's after leaving the thing plugged in for over 40 hours straight. TLDR: This thing is a waste of money which has now left me stranded more than once. I should have just spent the money on a decent pair of jumper cables, which this was supposed to be a more convenient alternative to.

once again I am revising my review of this product, but upward 2 stars this time after having used it awhile The first thing that impresses me with it is that I have abused it and it is only working better. I've run it completely down at least twice, which is bad for it and I wasn't charging it every time I used it like the instructions say, to do , which is bad for it. and the last time I ran it completely dead, was leaving the air compressor pumping my tire all night, which burned out the compressor as well as drove the battery completely down (lol but my tire was properly inflated in the morning). But the jumper part is still charging and working better than every. Also I'd wasn't following the instructions which say to connect the positive to the positive battery post and the negative to a chassis ground. instead, I always connected the negative cable to the negative post of the battery and it would barely kick my starter over. but today under the same conditions, I connected it to a chassis ground and it started quick and well, My previous negative review, which I am replacing now, was partially based on my improper use and abuse of this product. But i am leaving these parts of the old review because they are valid: .ALL the information about yhis product's power capabilities on Amazon and on the front in the picture are A BALDFACED LIE, according to the finely printed specs on the back of it which say "350 amps instantaneous" and "225 Amps continuous for 5 seconds", which means the "700 amp" claim is totally without merit and the "350" dubious because it cannot be used to start a car. I just WISH AMAZON WOULD REQUIRE it's sellers to PROVIDE TRUTHFUL, USEFUL specs. The product info Amazon provides usually HAS NOTHING TO DO WITH THE PERFORMANCE OF THE PRODUCT, which is definitely NOT " the most consumer-centric" LIGHT: IT IS ABSOLUTELY WORTHLESS:Trying to use it too hook up the jumper cables I would up having to get a flashlight. The problem with the light is that #1, it's not bright at all and it's not wide either. I have once watch battery cell keychain led lights that are brighter. And trying to aim the light on what you are doing while using this for, say airing up a tire or jumping your battery, is next to impossible because the beam is so tiny and weak. keep this product charged up to full or it won't start your car when battery is very low, probably won't even start car unless battery is only slightly low. It's good for starting lawn mores motorcycles and other small electric start 12 volt engines.. good cordless portable for inflating tires. Using USB ports run this product down surprisingly fast. inexplicably has covered other weather covered ports, but USB ports are not covered. battery power display leaves a lot to be desired.but then this is very inexpensive and worth the money. Just don't expect it perform like the amp rating suggest it should, because it doesn't seem to. Starting a car with a slightly run down battery with this is hit and miss. If it was truly 300 amps, that is PLENTY of power to add to a run down battery and jump a car, so this must not be 300 amps like i believe that a unit that actually puts our as much as this one claims would cost about $200. But It is very convenient for inflating stuff and quick portable power and it only cost me $40. But if you want unbridled reliable power, pass this up and get another product, another brand, that is much bigger and heavier, as much as like a car battery, such as a Snap-On or Mac and pay $200 or more for it.
