20 ft 4 Gauge Jumper Cables with Carry Bag– Premium Heavy Duty Jumper Cables & Roadside Assistance Auto Emergency Kit – Exclusive Roadside Assistance Booster Cables 400 AMP – Gifts for New Car

I got the jumper cables two days after ordering. Nice. They replaced a set of much cheaper cables whose rubber jackets had deteriorated substantially and probably became dangerous to use. The set I got from Sarah's Source LLC are hefty. I've already had to use them. One of our cars has been in storage. We're in the northeast, so it gets cold and its battery died. Alas, I didn't back the car into its garage, so I needed an extra-long jumper set. No problem. These cables were long enough to go the length of the car. Started immediately, so enough current was travelling along the 20-foot cable length. Another nice thing about the cables: the handy instructions, right on the cables themselves, just in case you're not 100 percent certain which negative lead goes to the battery and which goes to a good ground. Another nice thing: the handy-dandy bag. The cables are clearly heavy duty and their rubber jacket appears like it will hold up for a long time. And the clamps hold the battery terminals snugly.

I've had lots of jumper cables over the years and these are hands down the best I've owned. Most jumper cables out there work (or can be made to work) so it's the details that matter when choosing one. That's where these really shine. Extra long length eliminates the need to position the donor car in a possibly inconvenient or even dangerous position relative to the receiver. That can be a big deal. The clamps are very robust with good clamping force. Much higher quality clamps than I've had on most previous cables. Finally, the bag is really a convenient, compact way to store the cables in the car. (Why don't all cables come with this??? A very sensible add.) We'll see how they last over the long term, but I'm very pleased with this purchase. These cables with the storage bag hit all the right buttons for me. Highly recommended.

I had an old set of jumper cables that hung out in my vehicle, a tangled annoyance I'd regularly shove out of the way because some day I'd need them. But when that day came, they weren't nearly long enough to connect a vehicle in a garage to one on the driveway. So I ordered these and they worked terrific- the clamps are strong and the cables are really heavy-duty. And as an added bonus, they easily coil up and fit neatly in the storage bag, which is awesome. All in all, quality cables at a great price-point.

Heavy duty, nice and long, good quality clamps. Do not skimp on cheap-o jumper cables you will only be disappointed. The escape tool that comes with the kit is OK but it's very small and may not do the job in an emergency unless you are seriously motivated to cut and smash your way out of a burning / sinking / crushed-by-a-100ft-monster situation. But other than that they will do the job even for most small and medium size cars and trucks, including most small diesels.

This appears to be a great quality product. The cables look to be well made and not cheap stuff. The carrying bag is a great addition to keep the cables confined in the car back. And the glass breaker-seat belt cutter is a bonus we never hope to need, but if we should need it, it will be great to have--if we can find it in the car! We know safety glass will not break easily without a sharp pointed tool. Including this tool is a great idea! Perhaps it should be tied with breakable thread to the end of the drivers seat to be in reach of the driver if an accident should occure and it is needed.

I was pleased with the appearance of the cables when I received them. They are nicely finished and the storage bag is handy. Always hated getting out a tangle of cables when I needed them. I found their finish and appearance to be very good. Also, even though theyre heavy gauge, they're not stiff and hard to manage. The clamps could be a bit heavier but are plenty strong to provide a good grip on the battery posts. At 20' I didn't notice any amperage drop and started my big V-10 quickly. BTW: was amused by the negative review about no starting a diesel pick up. Don't think it was the cables. Most likely either the supply battery was weak or the discharged one was shot. These cables should do the job for just about everyone and I'm going to order another set to carry in my motor home. Buy 'em, you'll like 'em!

This are great jumper wire cables and I thought that the bag is gonna be way too big from pictures of the bag I saw but is a good size it can be fit under the seat and the wire insulator is nice and thick, the gator style clamps are good enough it comes with a small tool sort like emergency seat belt knife in case you get trapped you can cut it out, the hammer to break the glass windows is not so heavy but it will do the trick I mean is not a top of the line but is good enough :)

Used this immediately to jump start my bike from my car battery. Worked like a charm. Good, sturdy gauge, and the clips felt like they had enough grab. IMHO, this is the perfect length for jumper cables. So glad I didn't go with 16'. Comes in nice bag with draw string, doesn't take up much space. Took me forever to decide on a brand due to the mixed reviews of the others. Happy with purchase.
