Clore Automotive Jump-N-Carry JNC1224 3400/1700 Peak Amp 12/24V Jump Starter

I purchased two of these over the past 4 months for two different locations. This thing is a beast! It is heavy, first and foremost. This is not a toy. It is not a small lithium ion starter you buy from HF. This jump box is well built, and strong and will start just about anything! I literally started a Cat 977 with two dead batteries and the machine had not been run in years. This jump box did not even flinch! I have started many trucks, from F250's up the tandem dump trucks without any problems. You get what you pay for and this is a good value for the month. It is simple, no frills, no modern electronics but it does the job and does it very well. Know what you are doing when you use it because there is a lot of power coming from this box.

I purchased a JNC 660 a while back and so far so good for powering 12 V DC items through it's DC port. Thankfully I have not had to use it for jumpstarting any vehicle so the jury is still out as far as performance as a jumpstarter. I decided to purchase the much larger / higher battery capacity JNC 950. My JNC 660 arrived fully charged. This 950 arrived with the Battery Status Gauge showing a full charge of 13.5 V. I plugged a small portable CB radio with a CLA adapter into the DC socket on the side of this unit and to my surprise there was NO power at all. I tried a second small device in the DC socket and again NO power. I decided to charge the unit a full 24 hours as per the instructions through the AC wall plug.Once again NO power at the DC socket. Either the DC socket is defective or the Battery Status Gauge is defective or finally the battery may be defective. I have not tested the battery in this unit. Clore Manufacturing is closed on weekends so I have to wait until Monday morning to hear from them. Due to Amazon's Hazardous Material "NON" Return Policy they will not take the item back, which is ridiculous in itself because it is OK for Amazon to ship hazardous material to paying customers but it is not OK for customers to ship hazardous items back to Amazon for a refund ??? At the moment I am stuck with a $300.00 paper weight, not to mention the fact that it is going to cost me a small fortune to ship this garbage back to Clore. UPDATE: The people at Clore were very supportive and understanding about the issue with this unit. I sent it back and within one week I had a NEW unit with a working DC socket. The old unit had been shipped without a Negative(-)lead connected to the DC socket.

Finally a jump start that works! 900 CCA AGM battery that was fully dead!! I'm replacing the battery but I can start the car to get it moved without a tow truck company/service. Cable length could be longer but it doesnt make me rate it less. Worth the money!!! Shipped fast.

This is an excellent heavy duty jump box. I have not come across a single car that it won't effortlessly start. I work at a junk yard and use it to jump cars with dead batteries and even no batteries all the time. Starts anything from a little Honda all the way to big diesel truck. We also use it to jump a CAT 950G Front end Loader that is 24V. It jumps that without hesitation as well. I can also leave it plugged in overnight and use it to jump cars all day long. It will easily start completely dead cars without hesitation all day on a single charge. The other big reason we got this is because it actually has a smart charger on it. You can leave it plugged in and it maintains the battery. I've had one of these for over 5 years and have jump started hundreds of vehicles and it worked just as good being 5 years old as it did day 1. It finally gave out after one of my friends hooked it up to his car backwards and left it on with the car running for about an hour. I probably could of just replaced the batteries but I ended up just buying a new unit since the old one help up so well. I keep the old one around as a backup as it still works as a last resort. My only complaint is the weight of the unit, but for what we use it for, we need something that last all day and can start many cars and some of our heavy equipment.

Stopped working after 2 months – can’t start my truck anymore! I bought the Clore Automotive JNC1224 jump starter in December 2024. At first, it worked great — strong power, easy to use, and seemed reliable. But after only 2 months of use, it completely stopped charging. Now it won’t hold any charge at all and is completely useless when I try to jump-start my truck. I rely on this tool for work, and it let me down at a critical time. This is a $380+ product — I expected much better durability. Pros (while it worked): – Strong initial power – Easy to carry and use Cons: – Stopped working after 2 months – Won’t charge or jump-start anymore

Item was just as expected and arrived on time.

Cari pump you could ask for. It speed is great for charging. It’s great for the money. The capability is amazing. I’ve had no issues and I used it quite often. Great buy!

I have had many smaller lithium jumper packs. Including ones rated for diesels. They all died after less than 1 winter. I have had smaller lead acid ones like this. They worked for mowers and 4 wheelers, not pickups. This one I use to start everything with it. Not big enough to use alone on a semi with 3 dead 1000 CCA batteries and below zero F temps. It sure helps. It keeps working after trying. This situation is a lithium jumper pack killer. The built in charger did die in it. I charge it with a battery charger. Hook the big jumper clamps to battery charger jumper clamps and charge it. It works.

If you are looking for a handheld jump starter that can handle both 12-volt passenger vehicles and 24-volt commercial equipment (semis, farm tractors, construction machinery), Clore Automotive is widely considered the gold standard. ​Key Specifications ​12V Mode: 3400 Peak Amps / 850 Cranking Amps ​24V Mode: 1700 Peak Amps / 425 Cranking Amps ​Cable Length: 46 inches ​Cable Gauge: #2 AWG Welding Cable ​Weight: ~40 lbs ​Battery: Twin "Clore Proformer" Batteries ​Higher Cranking Power: With 850 Cranking Amps in 12V mode, this unit has a slight edge in raw power over the Truck PAC model. It is the better choice for large displacement diesel engines that are cold-soaked in winter. ​Simple Interface: The voltage switch is a simple plug-in selector. You plug the main connector into either the 12V or 24V socket on the front. It is foolproof and physically disconnects the clamps when not in use. ​Durability: The case is molded from high-impact polyethylene. It is designed to be thrown in the back of a service truck. ​Serviceability: Like most Clore products, the batteries are user-replaceable. When they eventually die after a few years, you don't throw the unit away; you just buy a replacement battery kit. Overall great product for personal and professional use.

I work for a mobile mechanic for a landscaping & construction Company, we keep this unit in our service truck and we use it all the time from company vehicles all the way to our largest heavy equipment. this tool is a must have!

Works great on my 24v equipment

le produite semble bon , sauf que après 4 mois d`utilisation occasionnel, la batterie int. ne se recharge plus et impossible de retourner !! faut contacter le fabricant pour la garantie , mais aucun service n`est offert en Français pour ce produit qui est vendu au Québec !! je vais plutôt acheter au Québec dorénavant ! merci

excellent product will boost anything
