"The reason these are so inexpensive is the type of insulation that was used. SJTW. It is thermoplastic. Better cords are SJOOW, use a synthetic rubber insulation that make them more flexible, especially in colder weather. Both of these cords are "weather resistant" but the more expensive one insulation is "oil resistant" on the inner and outer layers."
"If you live in an area that gets cold, I'd really avoid PVC or SJTW jacketed cords. They get super stiff once the temperature drops.
Look for SJOOW, SOOW, or SJEOW cord as mentioned. They will remain flexible even in extreme cold. I find that these cords also tend to hold up better than SJTW cords. "
"If flexibility is important to you and/or cord memory ie. becomes permanently twisted then avoid any cord composite that has "T" in the makeup. T = thermoplastic, which means it becomes stiff in cold weather and also is prone to warping over time."

about $10 cheaper then the one i got last year in august
there is a verrry good chance that you will get a cord made elsewhere, but not in the usa.
This one works.

That said, 20A outlet is irrelevant to the discussion, because the 5-20 adapter plug will fit into a 20A outlet, but not into either this extension cord nor the 10 gauge cord he linked (even though both extension cords will plug into the 20A outlet, both only have a 5-15 female end). So you are right, both extension cords only accept the standard 5-15 adapter, which will limit to 12A.
This one works.
That page shows a table listing the miles-per-hour of charge for various amps and voltages of the different receptacles you can plug into. And the 20A 120V connector for the Tesla portable charger does support 16A max draw (because the NEC considers EV charging to be a continuous load, so it de-rates the circuit to 80%.)
Also great for my 15amp (might be 14.5amp?) electric pressure washer, although I use a 50ft for that one.
Think I paid this or close to it 5-6years ago, so probably a pretty decent price in this crazy day and age. 🙂👍
*I also have this brand (US wire and cable) in 50ft and it's great as well. Seems like it is the same product almost to southwire brand. Obviously I'm no expert, but if you are price watching, I think this is a good brand to keep an eye on for 50ft 12/3 cords.
Paid $30 for that one in 2015 and I use it a couple times a month, has held up really well.
