JNC345

Hello Amazon, i have had many different jump starters over the years. I have owned 2 gb70 from noco, they were great, but because the boost will stay on untill the unit is shut off, they just dont seem to last as long. Have also owned 2 jnc325 and like them better then the noco because the cables are longer and the boost shuts off after 30s and comes in a pouch. I think the 30s boost will make the unti last longer. I did break a clamp on the jnc 325 but now they come with different clamps so hopefully will not break again. Have also owned a couple cheaper jump starters. This is my second jnc345, the first one was purchased back in 2022 , it is the 1st gen 345 so it is different then the one you get now. It has always worked flawlessly. I gave it to my son for his roadside jump starts because he always borrows it, even though he has a jnc325 and a jfegwo4000, he says the jnc345 is superior. Never fails him or me. Before i gifted the old jnc345, i tried to find somthing better then my 345. I bought the new v4000hd but returned it because the cables are to short and i didnt like the all metal design. If it fell over while jumping it could touch the terminals and cause a problem. I then bought the new gt truck pro 10000, i likes that it was not all metal, and i liked the clamps better then the v4000 but its design makes it tip over very easy. That tipping over and the kinda short cables means it will most likely fall over while trying to jump anything. So i returned that as well, and purchased the new jnc345. It has the new max access clamps that come on the 325 now, not the ones in the pictures. It has 40in cables for hard to reach areas, it now has usb-c charging as well. In my opinion these jnc345 are the best lithium based jump starters out there. For jump starting clore is the best, if you need to use your jump starter for other uses, like powering a small winch or somthing, i would buy noco gb70 or 150, not the x series bacause they stop the boost after one minute. The 70 and 150 both stay in boost mode till you shut them off.

Will jump anything I’ve tried with it. Excellent product. Thinking of keeping one in each of my cars. I’ve used for my car and to help start others. It’s convenient, compact and powerful!

Works great

The JNC345 is one of the few products with leads long enough to reach the manufacturer recommended jumper points for the 2021 RAV4 Prime / PHEV. The JNC325 is a few inches too short to reach the jumper points comfortably on the 2021 RAV4 Prime / PHEV.

Does not work on a bad battery that has an internal short! At least not consistently, but great on dead or weak batteries. However you can always disconnect battery and hook straight to cables "use bypass mode" then alternator will run car till you reconnect battery. The unit must sense some resistance to work or it thinks the circuit is open, but not so little resistance that it thinks there's a short.

This Jump N Carry box is designed to shut off it's power after 25 seconds of on time! Absolutely STUPID function of shutting off after 25 sec. - just about the amount of time to go from under the hood and into the driver's seat, get the key in and try to start it. We bought 2 of these - will return these and go back to NOCO GB70's which don't shut off until you power them off - MUCH more suitable for busy shops like ours! We don't have time to go back and forth trying to beat the 25 second timer. I called Jump n Carry and they said they included this 25 seconds until shut off as some kind of "Safety feature" and they have no desire to change anything. It does work to jump start a vehicle - as long as you can get it started within 25 seconds of the time you turn it on under the hood. This would be fine for a homeowner who only discharged his battery, but not for any car that may have a problem making it difficult to start. We have used the NOCO boxes for years, and these are lighter weight with longer cables - but the HUGE drawback is the 25 second timer. We only crank the starter a maximum of 5 seconds per cycle and then let the NOCO box rest for 30 seconds, but with this stupid 25 second shut off, we have to keep going back and forth under the hood to start anything. Too bad Jump n Carry designated such a stupid 25 second shut off feature into the otherwise high quality jump box! If Chlore just wanted to make it safe, they could just leave out the internal battery! It's back to NOCO jump boxes for our business

This is a good product to purchase, as I’m a security officer at a hospital and we assist visitors with this model, JNC345. After having used it on several occasions I purchased one for myself and in turned I’ve assisted an individual at a grocery store not long after receiving it, as there were other men on scene with jumper cables having already tried to start this car before I had arrived, told me the battery had no amps. I stated to them to let me try mine, I hooked up my Jump N Carry and it started this car effortlessly. I’m glad I purchased this and do recommend this model JNC345, to anyone that’s in the market looking to buy as it’s a good item to have.

After a long search, I found this Jump Starter to be one of very few lithium battery packs that meet Underwriter Laboratories Standard 2743 (see photo). This UL certification is an important safety factor, and one major reason to seriously consider this product. Another convenient feature included with this Jump Starter is the adapter that can be used with a separate air compressor to inflate flat tires, sports balls, etc. Highly recommended product.
