These are copper coated aluminum wires. Not copper wire. They are less conductive than copper wire of the same gauge. I found out when i have to trim the cable to discover the shiny silver cores inside. Disappointed, another company that is cheating with coated wires.

If Monster cable could only see the copper inside this jacket. Normally when you cut a piece of heavy cable in the center and strip back the insulation you see nice shiny copper. Granted the ends may be oxidized a bit but they are open to the air - I cut this at the halfway point to make 2 shorter cable sets or 4 equal cable pieces. This cable, while being nice and flexible, looked like an old penny inside - heavily oxidized and ugly as sin. I suspect its reclaimed copper 2 times over without proper slag removal. That's the only reason I took away one star.

Also the crimp lugs supplied leave a tad to be desired, but they include some properly sized red and black heatshrink. You are supposed to put the stripped cable into the lugs then fold each half over the other with "electricians pliers" - My professional crimper was able to fold them but not close them tight on the wire, so out came the persuader - a 16 oz claw hammer and some cement. Yep - that closed the crimp nice and snug on the wire. Now it has a good snug grip. I did buy some professional #4 lugs at the hardware store made of copper like a shiny penny and my professional crimper did those justice, so their lugs are a tad sub par but you can put them on with just about anything. Alternately I could have hit it with a propane torch and fed some solder to it, which I may still do if there is excessive loss in the cable. I prefer soldered connections wherever possible.

I also bought some nice bolt on attachments at the hardware store for $2/pr that have a bar which snugs down with 2 ea 7/16 bolts and nuts on the back side.

Good quality cables, I purchased them for the cobra 1500 watt DC power inverter. the cables where a bit long for what I needed them for but I could always use the rest for other projects. They don't come with the 30 amp fuse though as suggested in the instructions. You don't really need the high amp fuse unless your using the DC power inverter and cables for an appliance that draws massive amps like an air conditioner or large home appliance in that case you should use a high amp fuse or your cables and power inverter may over heat and catching fire. I use my Cobra DC power inverter for my 1000 watt coffee pot and power tools like a drill and saw when I'm repairing or building a board fence in the pasture. The Cobra 1500 watt power inverter and cables work well for my needs, plenty of amps without heating up. I have a diesel 2500 Ram pick up and realized that the the engine compartment was limited on space to install the power inverter. If you have this problem you could do what I did, I cut a 2x6 board in the length of the passenger side battery and cut a groove in the middle of the board to run the batteries mounting screw though, it held the board tightly in place. I than bolted the power inverter to the board. Note: you have to mount the inverter to the board before you install it. So the inverter sits bolted to the side of the battery on a board facing up. The shorter you make the power cable the better your power inverter will perform. I used less than a foot of cable and I don't see it interfering with the battery in anyway. It works for me.

After reading the other reviews, I still decided to purchase this item. The cost of copper is quite high so I understand them wanting to reuse old material. The package includes two 4 AWG cables and, they claim one 8 AWG ground wire. While the 4 AWG power cables are close to that size, the ground wire does not even come close. The only thing 8 AWG about that cable is the insulation. The wire inside is, at best, a #12. I contacted Cobra to ask for a replacement for the ground wire, but they never replied.

Would I buy it again, Yes but only because a high quality kit would cost at least $75.00.

This wire is very difficult to work with. I had to trim to a shorter length and I found that the insulation jacket is distributed into the wire core. So I had to pick out a mess of jacket from the inner wire. The wire was also not bright and was oxidized so I had to spend 10 minutes scraping each individual wire stand in order to solder on ring terminals. But in the end, it is serviceable (but of low quality).

Very satisfied with these cables. For those of you who know, one end of these cables is tinned with solder, the other has a ring terminal with shrink wrap. (2) extra terminals + wrap included (red and black). These are fine stranded copper wire which makes them very flexible. The other reviews that say they are aluminum or 'questionable' copper are wrong. The end is tinned with solder. I know they are fine stranded copper, because I cut them and stripped back the the insulation to make shorter interconnect cables.

So don't worry about if they're copper or aluminum or questionable. THEY ARE FINE STRANDED COPPER CABLES, with one end tinned with solder to go into your inverter. Very good cables for the job.
