Clore AutomotiveJump-N-Carry JNC770R 1700 Peak Amp Premium 12 Volt Jump Starter - Red

Great productThe battery last a long time. Have jumped my car a few times and my f250 7.3 super duty. Used it to put 30 psi of air in my tires with a portable pump plugged into it and it still had plenty of charge to jump my truck with a couple of weeks later. Awesome product and a great buy. Thanks guys keep up the good work

This is super heavy - which was clear in the product description. The most important thing for me was that the cables are long enough to reach my battery down in the hold of my boat. And these do! It also is much much easier to use than my old one, which had a series of convoluted controls. This is super simple to use, turn it on, turn on the boat. Yeeha.

Solid unit that works as described. Heavy, but good handle and clamp mount tabs have a good design over most

Easy to use and transport.

I LOVE IT! Best brand out there.

It's a Beast. I have a couple of different jump packs and this one easily is the big dog.

My job requires me to jump-start multiple vehicles a week, and I have always bought Clore Automotive jump boxes for the past 10–15 years. The old ones could jump-start 50+ cars before needing a recharge, but this one dies after just a few jumps. After two jumps, I can see the voltage drop from 13.5V to 12.6V, and after two more, it’s already down in the 11s, requiring a recharge. This is completely unacceptable for a jump box of this price and weight.I usually buy the blue one, but the last one I purchased lasted only a year and was noticeably lower in quality. I asked other car dealers about their experiences, and they reported similar issues. So, I decided to upgrade to the more expensive model—and it is even worse. I would not purchase this jump box again.

First, one thing I have learned is when you get something from Amazon, open it and check it promptlyregardless of when you will actually need to use it or gift it.I opened the box for my new battery charger and as soon as the top was open, I saw the light!The light on the top / front of the charger was on with the plastic bag still around the entire unit.The light switch is recessed and has to be held in to turn the light on so, it did not get turned on in shipping. That being said I don't know if this was a New unit or one someone returned with the light on and it was never checked. The manual says it comes fully charged in one place and in another says to charge it for 24 hours before the first use. I plugged it in, and the "charging" notice showed up on the panel and the voltage was just over 11 volts. So, it is charging for the 24 hours and hopefully when I need it to work, it will. The good news is it is a really bright light and it didn't get hot enough, before I opened it, to set the plastic and box on fire. I had previously owned the JNC 660, which I bought in 2011 and it worked great until last Thursday when I went to turn on my car to meet some friends for golf and it was dead and could not be returned to life. So, really can't complain but make sure you chasrge it on a regular basis. You can sign up wiht the manufacturer and they will send you reminders to do a recharge on a regular basis. Nice touch since you really dont't think much about it until you need it to save your batt.
