These JYEARN 0-gauge, 30-foot jumper cables are built for serious power! The extra-long length makes it easy to connect vehicles, even in tricky situations, and the heavy-duty clamps provide a strong, secure grip. The thick, tangle-free PVC insulation stays flexible even in extreme cold, which is a huge plus. The included carrying bag, gloves, and brush are nice extras. Whether for emergencies or everyday use, these cables are a must-have for anyone driving larger vehicles or working in tough conditions. Highly recommended!

A bit difficult to store and keep untangled, they are however perfect for getting to the battery bay of my coach, on the driver's side middle, from the toad behind it or a good Samaritan that would be off to the side of the road. Having the freedom to connect to a battery bank and not be limited by the cables being connected to one another is a serious plus. The other aspect I like is a battery welding situation off road where the 30 feet of length gets one close to the welding work without having to manhandle batteries to get them close. These should be good for occasional stick welding on the trail side.

I recently picked up these 30-foot heavy-duty jumper cables, and they’ve been a game changer. The length is perfect for reaching vehicles in tight spots or when the battery is far from the other car. The quality is fantastic – they’re thick, durable, and the clamps grip securely without slipping. I’ve used them several times, and they’ve worked flawlessly every time. I’m giving them a five-star rating because they’re reliable, tough, and make jump-starting much easier. If you’re looking for long, heavy-duty cables, I highly recommend these!

This is a great set of jumper cables. The cable quality is excellent, and they're plenty long enough to use even if you're facing away from the vehicle that needs starting. The clamps are very sturdy, and the cables are flexible enough to curl up and store away in the included storage bag. They are really easy to use, and come with simple instructions. This is a must for anyone that drives. Great to have in an emergency, and they work every time.

I've been using homemade welding cable jumper cables for years, and these jumper cables are the only cables I've ever used that are better than mine. They support instant jump start and are more flexible when cold than my welding cables.

The Heavy Duty Jumper Cables (0 Gauge, 30 Feet, 1000AMP) are a highly durable and reliable tool designed to assist in jump-starting vehicles with 12V and 24V electrical systems, including gasoline engines up to 8L and diesel engines up to 6L. With a robust construction, these jumper cables are engineered to meet the needs of car owners, drivers, and mechanics who need a dependable solution for starting vehicles with dead or weak batteries. Here's an in-depth review of their features, pros, and cons:Pros:Heavy-Duty Build and Superior Performance:The 0 Gauge wire offers exceptionally high current capacity, allowing it to handle up to 1000 amps of current. This makes these jumper cables ideal for larger vehicles and high-demand applications, including diesel trucks, SUVs, and larger gas vehicles.The 30-foot length provides ample reach for accessing the battery of vehicles that might be parked in different positions, especially in situations where the battery of one vehicle is far from the other.Compatibility with 12V & 24V Systems:These jumper cables are designed to be used with both 12V and 24V battery systems, which means they are versatile and can be used for a wide range of vehicles, including cars, trucks, motorhomes, boats, and commercial equipment.They are specifically designed for vehicles with 8L gas and 6L diesel engines, so they are well-suited for both passenger vehicles and heavier-duty machines that might need a jump-start in emergency situations.Tangle-Free and Durable Cables:The cables are made with high-quality copper-clad aluminum (CCA), which provides excellent conductivity while keeping the weight manageable. The insulated coating is designed to be weather-resistant, making these cables suitable for use in a variety of environmental conditions, from hot summer days to cold winter mornings.The cables are flexible even in low temperatures, which ensures ease of use during emergencies, especially when the weather is less than ideal. This makes the cables less likely to stiffen or crack compared to cheaper alternatives.Powerful Clamps with a Solid Grip:The heavy-duty clamps are designed to ensure a secure connection to the battery terminals. They feature strong copper jaws that provide a firm grip on battery posts, ensuring a reliable connection and reducing the risk of slippage during the jump-starting process.The clamps are equipped with insulated handles that enhance safety by reducing the risk of accidental short-circuiting while handling the cables.Portability and Storage Convenience:The kit comes with a carry bag, making it easy to store the cables neatly and conveniently in your trunk, garage, or vehicle. The bag helps prevent the cables from tangling or becoming damaged during storage, and it keeps them organized and easily accessible when you need them.The compact storage also allows for easy transport, so you can always have them ready for emergencies when on the road, camping, or working on vehicles in remote locations.Safety Features:The insulated clamps and weather-resistant cables provide an extra layer of protection, ensuring that you can safely jump-start vehicles without worrying about electrical hazards or exposure to the elements.The color-coded cables, (typically red and black, however for reasons unknown, they decided that blue and black would work,) make it easy to identify the correct terminals during use, reducing the chances of mistakes when connecting the cables to the positive and negative battery terminals. At least they color coded the grips red and black. The red grips are on the blue cable.Wide Range of Applications:In addition to regular car use, these heavy-duty jumper cables are suitable for a variety of applications, including trucks, motorhomes, boats, off-road vehicles, and even equipment that require 12V or 24V power. Their long reach makes them perfect for situations where vehicles are parked far apart, such as in crowded parking lots or when towing vehicles.Cons:Heavier and Bulkier Compared to Smaller Cables:Due to the 0 Gauge wire, these cables are heavier and bulkier than lighter-duty options. While this provides higher amperage capacity, it may be inconvenient for those looking for more compact, lightweight cables.The 30-foot length also adds to the bulk, which could be a concern for those with limited storage space in their vehicle or who need to carry them around regularly.Not Ideal for Small Engines:These heavy-duty cables are designed for larger gas and diesel engines, and may be overkill for smaller engines (under 4L). For smaller cars and engines, you might find that a smaller gauge or shorter cable is more appropriate and easier to handle.If you primarily drive a compact car or small engine vehicle, these cables may be too powerful for your needs and could be less efficient than a lighter-duty option.Price:While the cables offer excellent quality and performance, they might come at a higher price point compared to lighter-duty or smaller jumper cables. This is a reasonable tradeoff given their durability, capacity, and versatility, but it may not be necessary for individuals who rarely need to jump-start larger vehicles.If you're only looking for a basic solution for a smaller vehicle, you may find that this set offers more power than is needed, making it less cost-effective for everyday use.Storage Size:While the carry bag helps with organization, the cables' large size still means they take up significant space in your trunk or storage compartment. For those with limited trunk space or smaller storage areas, this could be a drawback.If you're looking for something that fits neatly into a compact storage compartment, you may need to carefully plan where to store these cables.Conclusion:The Heavy Duty Jumper Cables (0 Gauge, 30 Feet, 1000AMP) are a high-quality, durable, and reliable solution for jump-starting 12V and 24V vehicles with larger gas or diesel engines. Their heavy-duty construction, long reach, and high amperage capacity make them an excellent choice for emergency situations, mechanics, and anyone who needs reliable cables for larger vehicles, trucks, RVs, or commercial equipment.With weather-resistant coatings, tangle-free storage, and secure clamps, these cables are designed to provide a safe, hassle-free jump-starting experience in a variety of conditions. However, they may be heavier and bulkier than necessary for smaller vehicles or those with limited storage space, and their price may be a bit high for users with less demanding needs.Overall, if you own a larger vehicle, diesel truck, or performance car, these cables are an excellent investment for ensuring you’re prepared for dead battery emergencies.

I purchased the “Heavy Duty Jumper Cables, 0 Gauge 30 Feet 1000AMP, Automotive Booster Cables for 12V & 24V Cars, Jump Starter for Dead or Weak Batteries, Suitable for 8L Gas & 6L Diesel, Includes Carry Bag” because I could use a good set of Cables.After both batteries died, without warning, in my truck with a Cummins Diesel, last month, I needed a decent set of Cables. I tried these today, to jumpstart a dead Jeep, which is a project in process, and these Cables (from my truck to the Jeep) cranked-up the Jeep right away … no leaving the Cables sitting for awhile prior to cranking.These are very nice, 0 Gauge Jumper Cables! They are massive, too! The Cable-Cords are a thick diameter, and the overall length is 30’! I love the way the copper ‘teeth’ of the bite clamps is situated because it allows for a more stable grab and connection. These Cables will start your engine in temperatures -40*f, which is very helpful in the winter. The bite clamps have a powerful spring, creating the perfect tension in the clamps, and the hand-grips of the bite clamps are coated to be slip-resistant.The Set includes a wire brush for scraping the terminals, and it comes with a pair of work gloves … then, everything stores-away in the nice, heavy-duty stow-bag, which is zippered with carry-handles.I’m excited about this purchase, and I’m extremely pleased with the performance of these Jumper Cables. I highly recommend these Cables for Diesel owners, and more! I would buy these Cables for all over again.
