I agree it seems a bit low, but the only info I could find on actual power draw is from a JBL support answer on bb's product listing for the Ultimate. The PartyBox 1000's manual says it consumes 150W though, so 180W might be a decent estimate for the Ultimate. (source: https://www.jbl.com/on/demandware...ual_EN.pdf)

The only way to know for sure is to plug the speaker into a Kill A Watt type device, crank it up, and see what the max power consumption is in reality.

In any event, this extension cord should easily be able to handle the power draw of his speaker (even if it's 3-4A), and a 16 gauge should be enough as well.
Right, but I have 2 Partybox Ultimates and just want to verify I can run both with one extension cord with zero hiccups.

For the longest time, I've been wondering: What's the purpose of using 12 awg cable if the rated limit is 15 amps for these extension cables?
Normally, 14 awg wire is capable of 15 amps and 12 awg is capable of 20 amps.
It looks like the reason is continuous use vs peak:
12 AWG copper wire is suitable for a 20-amp circuit, and it's a common practice in residential wiring. However, for continuous loads exceeding 3 hours, it's recommended to limit the load to 80% of the breaker rating (16 amps). - Google AI

Yeah, 12 awg is going to be best for power tools.

You also need to factor in resistance over distance.

The longer the cord, the lower the peak.

Oh sorry, didn't realize you were the same person who asked the question. With 2 on the same extension cord, I'd probably go with 12 gauge. But I don't see any reason it wouldn't work well.

Quote from Souka View quoted comment :
People in reviews claim it's stranded copper... but odd nowhere on product page it's listed.

Also, is it "Made in America"?
Notice the packaging and cord say:
"We've got it
MADE IN AMERICA tm"
This is a trademark slogan... I'm willing to bet it's NOT made in America.
Deceptive how the "made in america" is bold also....

Also, the proper labeling is "Made in USA", so this is not that... so likely made in elsewhere (China?)

According to the Federal Trade Commission, "Made in USA" means that "all or virtually all" the product has been made in America. That is, all significant parts, processing and labor that go into the product must be of U.S. origin

I'm sure it's a fine 12/3 cord, just don't expect too much.

My $.02
I grew up in a town with a Southwire factory. It's most definitely made in America! It's a family owned company as well.

For some reason I thought about the Office episode where Jim strung out red wire behind Dwight's desk to make him follow it and go search 😆

To prevent cords from being stolen, put some tape around some sections of the cord. Thick enough to look like a repair.

People have left my "repaired" cords alone. Even found one sitting in a parking lot after it fell off my truck.

Wow, the FUD is real in this thread.

Yes, these are made in the US (manufacturer's website).
Yes, they are solid copper (manufacturer's response to a customer on homedepot.com).
Yes, these are heavier than a lower rated cable, but it is 12lbs.


I only keep 12ga extension cords in my garage because I don't want to worry about finding the "right one" to safely run my equipment.

What you really want if cold weather use is expected, is the US Wire 99050 12/3 50-Foot SJEOW TPE cords, unreal flexibility. SJEOW is elastopolymer jacket, weather rated and oil resistant. Much much more flexible than the SJTW of this cord, which is weather rated but has a much less flexible plastic jacket that is more durable.

I prefer shorter lengths i can chain together. Easier to deal with and coil, especially since most of the time you don't need a 100 ft length.
Someone with more knowledge should weigh in, but I remember being told chaining cords together is not a good idea.

My understanding, for example, was that a 25' cord was rated to be used by itself only... and that same 25' section is not designed or intended to be part of a longer length and could potentially be bad as it wasn't made to be carrying a current at that length.

But like I said, someone with more knowledge should probably say for sure...?

Yup, a single cord has less resistance vs two cords to get the same length. Not a lot though, and not enough to make a huge difference if the correct gauge unless running high amp stuff for a long time.
Ideally a single cord is better, but for most, two 50 foot will meet the same needs as a single 100 foot.
Even better is have one 10/3 50 foot and one 12/3 100 foot.
The 50 foot will power most any household item continuously with no issues, and if you need more distance, you have the 100 foot. If you need even more, use the 50 foot from the outlet, then add the 100 foot to that.

I got this cord for my neighbor (widowed older lady), I have a generator that gives me more than enough power, so I put this through the fence and in through her doggy door for her to power her refrigerator/phone charger/fan if there is a power outage. She understands to not plug anything else into it, so I did not get a 10/3 cord. The single 100 foot run is better so I don't have to worry about the cord being unplugged somehow between my generator and kitchen.

Would something like this be enough to use with a JBL Partybox Ultimate powered speaker? According to JBL, the speaker is 1100 watts.
Overkill for only 1100 watts.

Great price for a 12/3 extension cord, especially one made in the USA. I've used Southwire cords before, and they hold up well
