Great jump starter to have around and it works great, has lots of power. Nice to have the emergency light, the power and the ability to double up as chargers for phone etc. Comes with a very nice carrying case which stores jumper cables, and charging cable. The display is nice to have and it tells how much battery juice is left and the power being dissipated when charging things. Nice to have in your car as peace of mind!!!

This jump pack replaced one I had before, and I really like the included case and built-in light. After charging it when it arrived, I used it to help start our small tractor, and it worked well, though the battery wasn’t completely dead. It feels solid, well-made, and has a nice weight to it. Time will tell, but so far, so good.

This jump starter is a total game-changer for winter! I used to have the Noco GB40 and got so frustrated—died after just a couple jumps when I needed it most in the cold. This one? Compact enough to toss in the glove box, starts my car instantly, and can jump multiple times without running out of juice! Super easy to operate, lightweight, and actually holds a charge like it’s supposed to. Winter emergency must-have, way better than the GB40!

I bought hoping that it will be powerful enough to start a semi truck as per manufacturer guidelines, but I didn't need it until now and the first time I tried to use it really didn’t help or do anything to start the vehicle, like it wasn’t there even was fully charged, badly my return window is long past so I ended with expensive NOTHING

The media could not be loaded. So far just out the box everything looks quality, all of the outlets work and it was delivered faster than the expected time.This jump starter pack for its compact size seems durable, this jump starter pack works very well as advertised. I've compared alot of these jumpstarters and this one is very powerful. It's compact yet still has the ability to start 12L Gas or 10.8 L Diesel. There are 3 usb. The type A output and type C output. It's so surprising to me how easily this starts a car even with a totally dead battery. The great thing is if you aren't able to fix your battery immediately, then you can still get around and start multiple times with this device. It's definitely gives me peace of mind knowing that this is always in my car. When using the force start feature it produced almost 17 volts which is great for getting diesels to start or vehicles that need some extra power. It Comes with a very nice carrying case which stores jumper cables, and charging cable. It also has fast charging which is super nice as it takes no time to charge. The display is really nice and makes it really easy for anyone to use and will not allow for improper use through its multiple safety features.The large screen is a big surprise!. Just connect the jumper cables to the battery, and the car jump starter screen displays "12V READY." Press start, and in just one second, my car comes to life! I am thrilled! If the starter clips are connected incorrectly, the screen prominently shows "SHORT CIRCUIT" and warns "DO NOT START." Additionally, you can easily see the battery level. Before starting, I charged my car boost to 100%, and after one start, the remaining charge was 97%, which gives me great peace of mind. This unit is very compact and portable but very powerful, and that's all I need. When my colleagues at work saw it for the first time they were amazed at how easily my car started and wanted to know where I got it. I am very much impressed by what I get for the price.I like that it’s not as large and bulky as my last old Jamp starter. This jump starter has dust covers over the charge and power ports. When you own a vintage vehicle that needs jump-starting almost every few days, you quickly learn the value of a good jump starter. This portable little device has saved me hundreds, if not thousands, of dollars for avoiding my car being towed by the road side. I am hopeful it will continue performing well for the long haul,but based on how it’s worked so far, I have no complaints. Buy it, this jump starter is your must-have car emergency tool for a worry-free driving season! I strongly recommend this portable beautiful little device to anyone who wants to drive and have a strong peace of mind knowing that you have a great jump starter in your car in case you end up having faulty battery on the road.

Many of my customers are very satisfied with this jump starter. They love the smart screen display, which shows everything clearly and prevents mistakes. The 960CCA power is also very strong; it can instantly start a car even if the battery is dead.

I give this a 3 star rating because: : LED Display brightness is extremely low, especially during the day. You cannot see anything on the display during the day. USB charging port is very slow, and is not a fast charging port. Tested it by connecting my phone with 85% power and it tool 2+ hours to fully charge phone. I'm 100% glad I wouldn't ever use the ports to charge up anything. The positives 6AWG jumper cable 8250a -- may not even need that much ever. Debating if it's worth keeping or returning because of the display brightness. Cannot afford to have a battery issue during the day and struggle to see the display.

Really strong jump starter i do roadside assistance with it and done over 70 jump starts with it and starts very dead batteries with no problem as long as it detects some type of voltage. I think the lowest is like 2 volts. The inly reason why i did not give 5 stars is due to short battery life it needs to be recharged after 4-5 jump starts.
