This is a combined review for the Jump-N-Carry JNC660, JNC311, and JNC318.
Back in November 2015, my car battery died on a particularly inconvenient day at work when I was dressed up and had an important presentation. Not life threatening - just inconvenient. The very next day, as I waited at the dealership while they installed a new battery, I ordered two JNC660s from Amazon (one for me, and one for my buddy who drove over to give me a jump start and waited until I left to make sure that my car kept running). I went with the Jump-N-Carry because of the many positive reviews over the years.
The JNC660 is rock solid...and weighs the part. It's not petite, either. However, it easily fits in a trunk or (in my case) on the floor behind my passenger seat. You need to have your own extension cord to charge it up, and it takes a while to get it all juiced up, but it stays charged for a long time. After about a year and a half, I finally noticed the charge meter drop a bit, so I plugged it back in to top it off. In other words, you don't need to make sure to charge this up every month. Charge it up, put it in your car, and forget about it (outside of checking the charge periodically).
The JNC660 inspires confidence, but like I said, it isn't small. After I bought two of them, I then started to see the much smaller battery pack sized units that other companies were selling (and that Jump-N-Carry now sells in the 311 and 318). I was _extremely_ skeptical that something that small could jump start a car, but I bought a couple, and the DO work. Well, the ones that I got do, anyway. I've had a ChargeIt! Jump in my car for about a year. I jump started my car with it just to make sure it would work, and after months in my car without being recharged, I got it out to jump start someone else's car...and it was still fully charged and worked beautifully. I love that little jump starter.
Enter the 311 and 318. They have a similar level of rugged construction to the 660, while having a big reduction in size and weight. Speaking of size, the 311 is noticeably smaller than the 318, and I prefer it. It's just a bit bigger than the ChargeIt! (and is more ruggedly built). I also like that they have flashlights on the front, which can be especially handy if you're needing to jump start a car in the dark. I'm nervous enough around car battery terminals - I definitely don't want to be fumbling around them in the dark.
I mention the more convenient size of the 311 because, if you're like me, you might have thought that they were the same size from the product photos and figured that for an extra ~$20, you might as well just go with the higher powered unit. Now that I have both of them, I'm going to carry the 311 in my car. The carrying cases are the same size, so you won't save any storage space - but it's just a slightly more convenient size to hold on to as your connecting up to the car terminals to jump start it.
That said, the 318 would be better for some of you. Here's what the 318 adds over the 311:
(*) It comes with a preheat option for cold weather
(*) It comes with the 12V accessory ("cigarette lighter" sized plug) that is optional for the 311
(*) It's rated for 8-cylinder engines, versus 6-cylinder engines for the 311
(*) It has a second USB power port
I have a 4-cylinder engine and live in southern Arizona where it doesn't get very cold, so the 311 is perfect for me. At about $100, I think it's well worth it. The 318 is still fairly small for a jump starter and adds some good features, and although I like the 311 better for my uses, it's still a nice unit. The 660, while significantly larger and heavier than the lithium units, easily fits into a trunk or back seat, costs about the same, and has more power. Honestly, I think all three are good choices, but I am really happy to see Jump-N-Carry making the lithium units. They are just do darn convenient for the average consumer.
