Review: So far so good. - I bought this as an extension cord for my fast charging Jackery Portable battery. The battery sucks up 1600 or so watts to charge and lighter cords get to hot. This is definately heavy duty! Feels far more dependable that what my local stores sell. So far this has worked perfectly. It stays cool. And I actually like that the end lights up so I know when its drawing power.
Review: Heavy duty - lol was perfect addition to my husbands all green tools in garage! Was given in a basket of all green tools! He loves!!

### ⭐⭐⭐⭐⭐ Great extension cord!
*by E***M on November 2, 2025*

This THONAPA 12 Gauge Heavy Duty Extension Cord appears to be very well made. I wanted a cord that was not made in China (package says made in Vietnam) and was UL Certified which this cord is. Considering this cord is 12 gauge it is very flexible and served my needs well. I would highly recommend this brand.
