4 Gauge Booster Cable Kit Makes it Easy to Jumpstart Your Car
4 Gauge Jumper Cables come as part of a booster cable kit that provides everything that you need to safely jumpstart your car or truck. The 4 gauge pure copper wire comes with 20 feet that makes it easy to jumpstart your vehicle from a variety of positions. This length is great for front-to-front, side-to-side, and even front-to-back hookups. The 450 amp rated cable can has the maximum amp handling power to help keep you safe.
4 Gauge Booster Cable Kit also includes a case, gloves, and safety glasses to make the job as safe and easy as possible. The color coded cables help you avoid confusion with easy polarity identification. This set is perfect for vehicle jump starting in all weather conditions. Terminal biting clamps are combined with a heavy duty spring to give you vise-like gripping power that holds tight when you need it most.
4 Gauge Jumper Cables feature 100% pure copper wire and jaw to give you the best conductivity and power transfer. The 20 ft length makes a front-to-front, side-to-side, or front-to-back hookup easily accessible. The vinyl coated clamps are protected against rust and corrosion so that you can be sure they are ready to use when you need them. Kit comes with gloves and safety glasses for added safety, and a carrying case for added convenience. Both the wire and the jaw are 100% pure copper to ensure the best conductivity and power transfer possible.
This is a nice kit these are the kind of jumper cables you want. 4 Gauge pure copper wire, 20 feet long so plenty of length and you get gloves and safety glasses. It also comes in a case so you can neatly store it in your trunk or where ever. Good find OP
The Peak cables are a cheaper price but not necessarily a better deal. The cables from Sears are pure copper and the ones from Sams are aluminum with copper on the outside. The Sears cables will conduct the power better.

Aluminum is used for conducting electricity all the way to your breaker box; you may even have it in your house for wiring. Aluminum wiring is what's used in my Cherokee 180 as well. You will get less voltage drop (IR loss for the nerds) across Cu; however, for jumper cables just give yourself an extra minute or two charging up the dead battery.
Can't speak to the quality of the Peak cables; however, Aluminum isn't a "bad" conductor, (about 60% S/m of Cu). And current flows along the surface, so technically most of the current is flowing through the Cu.
Would I buy the Peak cables @ 40% the cost....yes. But I also have a jumper box
fsu67 said: I got mine a while back on Sears deal of the day for $34.99, Very good cables! I purchased one back in May - June - July ?? for $40 online using paypal payment but Sears screwed up my $100+ online order (this and some other items) and I didn't want to reorder at that time (until I got a refund) but it took 1 month. I didn't reorder because I was really hoping to catch it at 50% off.
Nice find OP +1 , however I personally feel its overkill for ordinary folks, and they are paying for that overkill. I haven't needed to jump a car in over 12 years, I carry nice cables and they are much better than the cheap ones I used a few times about 20 years ago. Really even cheap ones will work. Now if you are a cabbie or tow truck driver then its probably a good thing to have.

I agree with everything in your post except for this. This statement only applies to alternating current. For DC, such as in a car's electrical system, current flows through the entire conductor. For more information, look up the term "skin effect."
barondeluze said: I would never get a Cu clad Al. Al is not a good conductor. You are better off with higher gauge pure copper. Surprised they even make these.
AL is not as good as CU for conducting, but still very decent. Those wires you see up in the air between towers are aluminum, and they work just fine for the power company. The wires coming into your house are almost certainly aluminum, and it is very possible that large amp circuits are aluminum too. (Some construction in the late 60s-70s used aluminum for all inside circuits). I'd have no reservations against copper clad aluminum for jumper cables, but if the prices is comparable, I'd probably go with copper---realizing that I wouldn't be getting a major performance boost for doing so.
AL cables will break down after a few uses. CU will last longer and handle the amperage of must jumps. I have had both AL and CU and will tell you the AL is easier to move because they are lighter but after about 5 jumps they stopped working and always got really hot. The CU never get as hot.
4 gauge copper has the current capacity of 2-3 gauge aluminum. Aluminum weights less than 1/3 as much as copper, so for the same current capacity, aluminum jumper cables will weigh roughly half as much.

Thanks for the trip down memory-lane with Oliver Heavyside.
