    Thanks. If you know the source for a 10/3 Gauge 25feet extension cord, please let me know. I looked, but could not find at that length or shorter. I actually only need 10feet, but that's even harder to find for 12/3 Gauge.

    What I did was bought a 25-footer on amazon, & split it in 2.

    One for the boat, one for our generator. All I had to do was screw on a couple new plugs that liwes & home Depot sell

    While Home Depot and Lowes appear to have 10 AWG with only 30A plugs, Amazon has plenty with these with the standard plug.

    And even a single 10 footer too.

    Really, I am not finding one at 10 footer. I found a few 25 ft ones, but neither is stated to be100% TPE (thermo-plastic elastomer) compound that remains flexible in EXTREME temperatures. One I bought tout to be "Tested in the harshest Alaskan weather conditions, the cords remain flexible down to -94°F!"

    Can you make it in SJEOW TPE jacket for outdoor use that will stay flexible down to -94F? If you can, please PM me a quote. I have had and used heavy duty 10 gauge extension cord that is made of SJTW PVC, but they become stiff as a stick in a middle of winter outdoor. I need one that stays flexible maybe not down to -94F, but certainly down to -40F. ;)

    This is 10 feet. It claims 'extreme temperatures', but then doesn't actually give the detail you ask:

    I was seeing many more choices at 25 feet, but didn't dig in for the other details you ask for.

    My current stock of 10 AWG is SJTW, but I'll briefly look into it & get back to you.

    This cord is the lowest quality on the internet...

    This is a Do Not Buy.

    if you are below - 30°F, don't bother charging, as traction packs are much more inefficient - to the point where it isn't worth charging

    Thanks, guys. I looked up. SJTW code is for PVC jacket. It may be rated for extremely low temperature, but my experience is that they become very stiff in low temp. SJE or SE are code used for TPE jacket. I can buy the 10/3 SJTW one on Amazon made of PVC and see how they behave in winter. Certainly, except for a few months middle of the winter, PVC will be just fine.

    OK, we don't get very many days of night temp below -30F. In fact, we probably have not had much colder than -20F in recent years. So, no problem in charging even in the middle of winter so far. However, I gave up charging whole month of last FEB because ICE would come on every morning when I start the car no matter what I did, and price of gas became ridiculously cheap, that it made no sense to pay for high electricity to run on EV.

    That being said, I want the extension cord to remail flexible at least down to -40F for safety measure. Even if I don't charge, the extension cord has to stay cold in an unheated shed.

    Now, come to think of it. My PVC extension cord gets hard and stiff in winter, but OEM EVSE cord remains flexible just like the TPE extension cord I bought. Does anyone know what material is used for the Toyota OEM EVSE cord? It does not feel like PVC, but not sure if it is TPE or something else.

    10ft of my 10 AWG SJTW = $49 Shipped.

    10ft of 10 AWG SJEOW = $69 Shipped.

    1st - there's a difference between stupid & ignorant. If you've never been taught, that's not stupid.
    2nd - there are other variables that you didn't mention. For example, resistance increases when temperatures are above 95°f. There is also resistance at termination points. This is why some chop off blade plugs & install twist-lock plugs. There is also more resistance in lower strand wire. This especially comes into play here because some posts here indicate they worry about stiffness in cold weather. 99 strand #10 is way more flexible than low strand #12.
