## Questions & Answers

**Q: What is the eva case mentioned for the extra few dollars?**
A: I'm not sure that option was available when I purchased mine. If you click on the link at the top which includes the EVA case, you can see a photo of it (and click on the photos at the left.) So instead of the nylon drawstring bag, you can get the upgraded zippered case for the cables instead. Note that the cables are easy to fit in to the drawstring bag. Having not seen the zippered case, I can't say anything about it.

**Q: Are the wires copper coated ?**
A: Most of the homes with aluminum wire had to have all their wiring replaced. It was a fire hazard disaster. If you are serious about getting a car to start, spend $10 more and get all copper wires for your jumper cables. Amazon has them right here. TOPDC - $26.99. Shorter is better too since power decreases the longer the cable. For most folks, 12' will be fine.

**Q: Where are these manufactured?**
A: It's made in China. But approved at UL office.

**Q: I realize these arent copper wires, but wont they work for the occasional use?**
A: With jumper cables, don't be consumed about copper vs copper clad. A few posters are obsessed over it for no reason. Copper Clad is fine for occasional use items such as jumper cables - you're not arc welding and don't need pure copper. The difference in cost is usually 50% or more. We all know copper conducts better IN LIKE FOR LIKE SIZES.  If you lean towards a heavier gauge copper clad wire, the difference is negligible. Again, we are talking about jumper cables, not welding cables or a home's electrical wiring (apples and oranges). 
To clarify some misinformation, Aluminum wiring that was used in houses for a few years was dangerous for various reasons unrelated to its use in jumper cables. It had to do with the different expansion rates between aluminum and steel used in older switches and receptacles, the failure to use an anti-oxidant paste on connections and the fact that electrical current was constant and/or cycled frequently through the wire which made the aluminum brittle over time. For the record, Aluminum wire in power transmission and distribution applications is still the preferred material today. The wire feeding your home from the street and overhead power transmission lines are still run in aluminum. Sometimes too little knowledge is dangerous because it leads to incorrect conclusions.

### ⭐⭐⭐⭐⭐ Easily the best pair of jumper cables I've owned
*by B***L on March 29, 2025*

Read the reviews, and these are at the top of the list on a couple of review sites. Nice and long, very supple/flexible, with sturdy clamps. Thought the length might impact charging capability but they work like a charm.
