CablesAndKits - AC Power Cord Extension (3ft) - C14 to C15-15A/250V, 14 AWG Power Cord - Heavy-Duty Power Cable for PDU, UPS, Electronics, Network and Data Center Needs - (Black)

Using this to extend a monitor cord without any issues (sit/stand desk). Cord feels well built and seems to have no issue or concerns when in use. Description was accurate.

Using several of these I'm able to extend the outlets from a power strip like an octopus under the beams of my awning for lights and equipment. Useful! No indication that this product has undergone safety certification by UL or any other company, as you'd expect in North America.
