I originally purchased this jump starter in July 2023 and was pleasantly surprised by how powerful it was. It's compact size makes it a great option for keeping in your vehicle, and it is much lighter than other bluky jump starters I have used in the past. There is a light that is built into the tool which is surprisingly bright and useful for low light situations. I was so impressed with the performance and price point of this jump box, I later bought two more to give as gifts to family members. Fast forward a year to July 2024 and the original jump box (purchased in July 2023) mysteriously stoped charging. Thinking I would just need to purchase another one, I decided to first send a message to the seller to see if there were any options to reset the tool. Their customer service team promptly replied asking a few questions about the issue and later determined it was a faulty unit. They graciously offered to send a replacement (even though I had used it for a year). I would highly recommend shopping with this seller!

Final update 7/16: Manufacturer shipped an M8 to utilize and test for functionality, and I can say that the M8 is what you SHOULD purchase for a reliable jump start pack. Now, I do realize the M8 is slightly more in cost than the M6, but the piece of mind that it will work when you need it to is worth it. I've tested it on a small four cylinder truck, an inline six trailblazer, and a Dodge Ram with the 5.7l hemi and it worked on every one of them on a single charge with 64% remaining on the display. It's easy to use you can't mess anything up because the M8 will show a symbol if you've hooked something up incorrectly; unlike jumper cables which can completely destroy modern vehicles and their electronics which is thousands to repair. Everyone has run into the "know it all" who can "fix anything" but who is going to be paying the bill when your vehicle is destroyed? Be safe and use a jump pack because there are too many computers in vehicles these days and it's just not worth it. It's user friendly, so all you need to know is where your battery is because the instructions are so easy to understand that it will guide you from there. Now, something is obviously different internally between the M6 and M8 models and I don't believe it's just the capacity, or rating, because the M8 performed completely different than the M6. So, if you want something to put in your trunk in case of emergency then I would recommend picking up the M8 over the M6. With the cost and time it takes for roadside assistance or AAA to show up the M8 will pay for itself in one use. In regards to the M6 and after following all of the instructions and hooking it to a small four cylinder truck with a weak battery. Nothing I did would get the device to start the vehicle, it just dropped in voltage on the display. I then looked over the user manual again ensure I wasn't doing anything wrong. I tried a few more times before grabbing a pair of jumper cables and hooking them up to Jeep which worked immediately. I charged it to full again and later tried it on a riding mower that's been sitting and this time it actually provided power; however, it didn't even have enough power to start the small lawnmower engine. After three attempts the battery level indicator was just above 20%. I'm not sure what battery cells they are using in these, but they're obviously not going to work when you need them most. I did like all of the accessories it came with and the display was actually very appealing! The battery cables were also decent quality and the flashlight would be useful if the device actually worked. Maybe I just got a bad one, I don't know, but I'll reach out to the manufacturer and update this afterwards. In the meantime, I'll be keeping the jumper cables in the truck. Update 6/26: Manufacturer shipped out replacement; however the replacement failed to jumpstart an inline 6, and I once again had to resort to jumper cables. Positives: the replacement did start the riding lawnmower, so that could be a good use for it. You could also use it to charge a phone. Will I keep it? No, because I need something reliable that works as advertised. Updated to two stars because the manufacturer actually responded and in this day and age that's pretty rare. Final update is at top and it's for the M8, but reflects the M6 flaws which should not be ignored. In my opinion, buy the M8 for a few dollars more and save yourself the hassle because there are a lot of other brands that look VERY similar. I have one of $400 N*** jump boxes in another service vehicle and the M8 is on par with it - I wouldn't be surprised if they're manufactured in the same factory.

I have only used this twice; each on a cold morning after not starting my pickup for several days. Both times it was still charged ok and started the PU right up first try each time. That drained it to 60% so I recharged and put back in PU ready for next time. It is probably time for a new battery but there were several months in between the jumps. Anyway, I am glad for it and the trouble it saved me and I have one in car also. Lots easier than getting another car there.

With 100% charge it will indicate the unit is overheated as soon as you attempt to crank the vehicle. It worked fine until I needed it after the hurricane. Now it is a brick... Good for nothing. I have purchased three other units from a different manufacturer. They are all doing their job after 18 months of service. I feel like I wasted my money. This one was on sale so I took a chance. Now I can't seem to get service or warranty. It is SUPPOSED to have a 24 month warranty if I read the description right. Just no way of contacting customer service. I guess if it doesn't die in the 30 day return period, I am out of luck and the money I paid. 7/23/2024 Update: Ultimately the company refunded me for the defective unit. It was well after the 30 day oeriod so I am thankful they stood behind the product!

I recently purchased the Mostool M6 3000A Peak Car Battery Jump Starter Battery Pack Portable Jumper Box. Unfortunately, my experience has been disappointing. When I first bought the device, I didn’t use it or open the box for two weeks. When I finally tried to use it on my Hyundai Tucson, which had a battery showing 10.2V at the time, the jump starter failed to work. Although the power bank indicated 100% charge, as soon as I connected it to the car, the device went black and showed no signs of life. I brought the device home and tried to charge it again, but it didn’t turn on. I understand now why people are opting for other brands. One major downside I noticed is the lack of a reset button, which might be contributing to the issue. I suggest spending an extra $20-$30 to buy a known brand jump starter. I have a couple of other brands that start with “N” and I’ve never encountered this problem. This product was dead right out of the box when I first used it. I also emailed the seller, but I haven’t received a response yet. good luck wit this brand svared to ask for replacement unit since who knows if it work or not when i need in my difficult times
