P100 Car Jump Starter, 5000A Peak Lithium Jump Starter Battery Pack for Up to 10.0L Gas or 8.0L Diesel Engine, Safe 12V Portable Battery Starter Power Pack with LED Screen & LED Light

I have had this jump start for about a year and a half and ir has never failed me, it holds the 100% charge for months with out taking it out of my jeep. It has started mu lawn tractor, my jeep, my son's ram 2500, and tonight it started his 386 peterbilt (he left his bunklight on all weekend it was dead) I had 99% to start and still had 79% after it started his semi. I sent him the link so he can get one.

This is my second time purchasing and I still feel this is a must buy for every car - especially if you live in the Midwest. One day a few years back, I was parked at the airport in the dead of winter. My car wouldn’t start when my trip was over and it was time to drive home. It was the middle of the night and I didn’t exactly want to ask some stranger at the airport for help, but I was kind of out of options. Luckily, there was a nice gentleman with a device similar to this. My car started in no time, so I purchased this exact item shortly after.By now, I have rescued so many other individuals in similar situations. Every time, I show them this device and explain how it works! There truly should be one in every car. The battery lasts ages and you could even charge a phone or tablet from it. This is so great to have in an emergency! The LED screen is simple to read and understand. Similarly, the jumper cables, connectors, and device as a whole are all easy to operate. Highly recommend!

This portable charger has saved me numerous times! The fairly lightweight, easy to use unit doesn't have to be charged on the daily which is good and whenever I've needed it, it's never failed. I had a car that had some unknown power drain, and if I didn't run the car every other day, battery pooped out. I resorted to keeping this jump starter in the car at all times...safety first!

So easy to use this little jump starter. Small and lightweight and holds its charge when not in use. I really like the safety feature that prevents sparking and reversed terminals. Totally impressive and started everything I've needed from 12V lawn mowers to my totally dead full size pickup truck. Love this thing!

Use this to jump off my 6.0 l diesel amazingly it jumped it off later that same evening our company truck which is a 6.7 l diesel was very dead the lights on dashboard barely work at at 72%, somehow it was able to jump back for a call now after that jump it did go down to 12%. It takes a good little while for it to charge several hours but so far it has been a very tendable box the options for charging cell phone on the side with USB port is also a very useful function me and my wife have used this several times and the ability to charge it off of your vehicle from a USB charger is very handy you can do it from in your home or your vehicle matter of fact if you're alternator is in good shape after you jump the battery off you can just turn around and plug it into your vehicle as you head home and it will charge both your battery and your battery jump box depending on alternators or whatever what's wrong with your vehicle but I have found it to be very handy and for the price I can't beat it and you couldn't either give it a shot I give it four out of five stars it is not the ultimate box but for its price I do not know if you can find one as good.

Works as intended, especially if you are boxed in.

This is very good, even started my diesel truck in cold weather, totally dead batteriesI will add this one won't stay charged more than a week

This thing is powerful and works great, can jump a car multiple times before needing recharging. Very compact and long lasting battery life.
