    • Convenient, Heavy Duty with No Heat Issues
Color: Black Size: 50A_20FT
This was an excellent purchase for my needs. It appears to be a quality, well built, 50A extension cable designed for EVs and functions as advertised. On connecting the extension cable to the standard 15 ft, 240V 40A charger cable for my two cars, there was no heat generated in either cable and if anything the charging speed honestly seems a little faster. I have two hybrid vehicles in my 3 car garage and with this 21 ft extension cable I could charge a 3rd EV with a charger port on the far side of the car in the 3rd bay. Eliminated my need to shuffle cars back and forth which was a pain in the rear! I'll provide an update a few months from now...unless I uncover an issue sooner. ... show more

    • The cable is thick and no micro-switch
Color: Black Size: 30FT 50A
The extension cable appears to be well built; however, it is very thick and rigid. More importantly, it does not include a built-in “micro-switch” in the charging handle button, which means it does not signal the charger to stop charging before disconnecting. I was using this cable with a J1772-to-Tesla adapter, and I specifically needed an extension cable with a micro-switch so the charger would stop charging, unlock, and allow me to safely remove the charging handle. After doing additional research, I found that EVDANCE and SEGUMA extension cables include this feature. Because this cable did not meet my needs, I returned it. ... show more

I have had this cord less than 2 years and the wiring harness connection has separated. I am not over stretching cord and I keep inside in house when not using. I am throwing away since I don’t need fire or damage to occur to vehicle. Looking for another manufacturer. It also no longer delivers 40 amp power I used Electrical tape over connection but this made me nervous due to high voltage. Cannot recommend. ... show more
