Thinking of buying a GRIZZL E charger.
Specifically a 14-50 with extra-long, extra thick premium Cable.
The thickness does make it heavier and a bit harder to bend but it's mainly the cord construction that can make it get stiff in cold temps. I used to really like the soft black rubber cords and while they generally stay flexible all the way to below zero they tend to really pick up dirt and dust as well as not the most protection for punctures. I've found the best cord to be a quality rubber cord but one that has a protective coating making it get far less dirty and easier to clean and also give it a bit more protection from abrasion. Again rubber is better than plastic/vinyl but coated rubber is the best. The orange cords while easy to clean and somewhat abrasion resistant get awful when cold, even in the 40s and many blue cords remain flexible in cold but are like the uncoated black rubber cords, coated blue or quality black seem to be the best for cold weather flexibility and abrasion/puncture resistance.
