The extra length is perfect for side by side boosting.
Strong clamp with copper contacts. Soft cable, wont get stiff in winter.
Quality product.

Not that impressed. Length is correct but lamps are copper coated on one side only and cables weigh less than my old 8' copper cables. The word Coleman is nowhere to be seen on the box. I use infrequently so will keep them but a good example of getting what you pay for!

Excellent product, these are the booster cables you need. July 5 2009
By G. Green - Published on
I have owned a pair of these for about a year, after owning a couple of cheaper pairs, and what I have learned is that there are three basic considerations when buying booster cables. First, the quality of product that the manufacturer produces. Poor quality cables will fail on you and possibly do serious damage to your vehicle. These cables are very well made and reliable. Second, the gauge of cable. The lower the number the heavier the cable. Four gauge is nice and beefy, and will do the job for any passenger car or truck. Don't go for a higher number (and therefore less capable) set of booster cables. Third, the length of the cable. It is inevitable that you will eventually have to use these to start a car that is boxed in by a garage, trees, or other vehicles and you''ll have to reach the battery from the back of the vehicle. Twenty feet is the minimum length. Get 25 foot cables if you can.

Coleman Jumper Cable Review June 23 2000
By "elouise25" - Published on
This 16 ft. Coleman jumper cable is a 4 gauge cable which is a mechanic's grade. It is durable and will last a long time. The length ensures that you will be able to utilize this tool without worry, the clamps glow in the dark and fit both side post and top post batteries. It comes with a lifetime warranty and I am very glad that I bought it.

Okay quality, not professional grade May 12 2011
By Mr.Dead End - Published on

I bought these because a previous reviewer said that the wire was solid copper. Either the model changed since that review or that reviewer was incorrect. These are decent quality cables, the clamps are sturdy enough, but the wire is definitely copper coated aluminum. It didn't occur to me to check the shipping weight, but when I picked up the box, I could tell that 20 foot, 4 gauge solid copper cables with heavy duty clamps should be heavier than 6.3 pounds. I haven't decided whether it is worth sending them back or if they are good enough to put in the wife's car.

heavy and bulky, otherwise great Feb. 16 2008

i wold not recommend getting a jumper cable this good unless you have frequent problems with your car.

i play a lot with different stereo components (amplifiers etc) in my car and i end up running the battery down dead quite often.

for me hauling around a 15-pound set of booster cables in the trunk is worth it because, for example, i used it twice within just the first week after receiving it - for most other people it may not be worth it.

the jaws grip super tight. actually its very hard to work them with just one hand because they are so strong - sometimes i end up using both hands to compress the spring - seriously i imagine many guys will HAVE to use both hands but this makes for a stronger contact. there are copper inserts in both jaws (so in 4 jaws in total) and some people prefer that although (of course) only 2 of the 4 jaws actually are connected to the cable directly.

the cable itself really looks like 2nd gauge - its almost all copper with only very thin (about 1 millimeter) insulation on top of it. this is unlike 10 dollar jumper cables which have almost the same thickness on the outside but are almost all rubber with a thin copper wire in the middle.

i ran into a bit of a problem with the insulation on the jaws themselves though. the red and black rubbery plastic on the handles is thin and not durable. when i gripped one of the jaws onto the handle of another it bit right through this plastic and started to spark. this is also a testament to how strongly the jaws grip - they bite right through insulation (so dont do that).

i never thought i would need so much length but actually its quite handy. we even managed to jump the car in-line parked with a third car in between our cars (but one of our cars had to be parked reversed for that).

for those of you who are not electrical engineers like me your engine needs a certain cranking current and to get it out of jumper cable the cable must have low enough resistance. resistance increases with cable length so if you have a big engine to start (bigger engines need more cranking current) and a long booster cable - it better be thick, because thickness of copper is what lowers resistance.

for my engine which is only 3.5 liters this cable is overkill but the only thing wrong with overkill is that you have to haul around a 15 pound booster cable in your trunk ... perhaps in extra cold weather when the engine is extra difficult to start the overkill might come in handy.

five stars - this cable is no joke

Not sure if they're really 2ga Dec 22 2010
By DeusEx - Published on

So these aren't the best cables you can buy. For that you'll have to go to an electrical or welding supply company and you will PAY! Probably between 3 and 5 times what these cost! So unless you plan to start a towing service and need cables that will see daily use, I'd say these are gonna work for you.

(Update: After compairing them to the 4ga cables I bought a month or so back for my car, they don't really seem that much thicker... That's said they are MUCH heavier! The individual stranding is of a thicker gauge than the other model so I'm guessing that's why the thickness isn't much more...)

What I like:
--Length - I bought these for a half-ton pickup. Why? Because it never fails that your battery will fail to start your engine when your parked in a packed lot with cars on all sides. Rather than pushing a 3 ton vehicle out you pull the booster vehicle in as close as you can and let the length work for you.
--Heft - these cables are no joke. It's a workhorse grade cable that lets plenty of energy flow. When trying to start a 5.7L V8, that's kinda important.
--Solid Clamps - Unlike some of the other reviews, I don't have a problem opening my parrot clamps with one hand. But their hardly weak, they'll clamp solid and stay put!

(Update: If you really need 2ga booster cables and your skeptical of these, Deka makes a set of 2ga cables for around $150. I have no personal experence with them but I have a little with the Deka name and they seem pretty good.)

What I don't like:
--Stiffness - They're not as flexible as I was hoping. But about as flexible as I expected. True welding cable in 2ga is about $3 per foot and per cable. That's why the best jumper cables cost $200+. Still I was hoping for a little thinner stranding to promote flexibilty.
--Cable to Clamp - Like other reviews have mentioned the cable doesn't go all the way to a copper contact connected to the jaws. Instead. It's screwed to the body of the clamp then the copper jaws are also screwed to the body. Still fine I'm sure.

So why buy these cables aren't they overkill? I've had this argument with people before: "My 6ga cheapies start my truck fine." Well I will attempt to addess this. As the number in terms of gauge decreases the ammount of conductor increases. In other words 2ga has more (perhaps 50-100% more) conductor than 4ga. This doesn't automatically equate to twice as much power but it does certainly allow more power to flow safely. For those that aren't aware (and I'm not an electrical engineer here), resistance is the enemy of all electrical circuts. Resistance translates to heat in the same way that friction does when two physical surfaces rub together. Five basic factors contribute to resistance in a give curcuit and determine the appropriate line size. Ambient temperature, conductor, line distance, voltage, and amperage. Ambient temp we have no control over. Hot is bad so just assume the worst. This means bigger cable to overcome the additon resistance heat is producing. Conductor of these is copper so that's good. You want pure or at least a high purity mix of copper in this type of conductor. Distance and voltage. One of these cable's strengths also happens to be a weakness. Total run length for this circut is 50'. Pretty long for a low voltage system like 12VDC. The higher the voltage, the longer it can run on a given gauge wire without encountering too much voltage drop. 12VDC drops voltage on a circuit in a realatively short distance. So heaiver gauge lines are needed to prevent this. Amperage is also a big consideration. The more amps a load pulls the more resistance the circut will generate. Basically on a small wire, a large load will generate a lot of heat and one of two things will happen. 1) the wire will melt and/or catch on fire. 2) The load your trying to power won't work. And make no mistake, starting even a small engine takes a LOT of energy! So bringing it all together. Large load, low voltage (that we don't want to make in lower), and a long distance run means that you wan the heaviest cables you can find. Addressing the orignal question and statment. 6' 6ga cables might start your small-block fine. But if you want or need the extra length, you need to consider heavy gauge cables. That said I've personally seen light duty cables melt and smoke from starting an engine too big for them.

Are these right for you? So these will run you close to $100 you actaully need them? I own both these and the Coleman 4ga 25' booster cables. Having no offical training and with no real sizing charts on the packaging I would say this. The 4ga will do you fine at the 25' length for engines up to 5-liters or so (and honestly probably up to about 6L as well.) Anything bigger than that and you should be considering these or something even better.

Also protect your investment. Buy a cable bag for them to keep them neat and protected. Also keep the twist ties that came with them to keep them organized inside your bag. I have the Arsenal #5888 cable organizer and it works great for this. Remember too to clean and inspect your cables after each use to prolong their life and keep you safe.
