Key specs (as listed)

What stands out

The listing is the least consistent in this group. One bullet says the factory chose 18 W/ft, while another lists 120V 5 W/ft, and it gives the plug wire as 24 ft, which is unusually long. It also mentions UL “and other standard” in one line without naming the listed component. Before buying, check the label photos and the product Q&A for the real wattage, and confirm the certification on the cable itself. If the listing details matter to you, the JDZKOMKE or Rylpoint listings are clearer.
