Use caution if using with Kill-A-Watt - only rated for 10 amps!
This product is fine if you are just using it to free up space on your surge protector or UPS that would otherwise be used by A/C adapters for cell phones, speakers, etc.
However, this cord is only rated for 10 amps. Unfortunately that is not disclosed anywhere in the promotional materials. This means you can only use it for electrical loads of up to 10x125 volts = 1,250 watts. So if you were intending to use this with a Kill-A-Watt to measure, for example, how much electricity your refrigerator or microwave uses, well, don't do it because those appliances may draw more than 1250 watts and overheat the wire, possibly causing a fire.
What is needed for use with the Kill-A-Watt is an extension cord that is rated for 15 amps or more. That will allow safe transmission of the electricity over the extension cord without overloading it.

NOT as Described
The description includes "NEMA 5-15." This indicates it is rated as 15 Amps (and 1875 Watts at 125 Volts); the "15" in "NEMA 5-15" refers to the amperage rating. (See the chart at en.wikipedia.org/wiki/NEMA_connector#NEMA_nomenclature.) However, the item I received has a tag attached that says it is rated at only 10 Amps. See my two images.
To examine the cable it would seem to be well made and good quality. But the attached "10A" tag means the inferior quality is in the gauge of the conductors. The cable is stamped "18 AWG," i.e., 18 gauge, the maximum safe load of which in this type of three-conductor cable is 10 Amps. The specification "18 AWG" does appear in the description, but is not directly recognizable as implying the 10-Amp limit and is easy to overlook and/or disregard (as I did) in the presence of the immediately recognizable spec "NEMA 5-15" that indicates 15 Amps directly.
(NOTE: There's no simple chart for current capacity because there are many factors to be considered, including conductor material and gauge, insulation, ambient temperature, number of conductors bundled together, and application circumstances. Caution must be exercised in simplifying, but generally in typical household usage an 18 AWG three-conductor extension cord such as this has a rating of 10 Amps, as the attached tag says. For a rating of 15 Amps it would need to be at least 14 AWG. See, e.g.:
Given that the 1-ft cable was an Add-on Item that got me free shipping, a return isn't worth the hassle and I will find a suitable use. But I would recommend only as above qualified (10 Amps), and would NOT buy again. And I reprimand Amazon for its inadequate care in gathering product info and publishing accurate descriptions.

Lower Amperage Limit - 13 A
This extension cord is only rated for 13A, so be cautious when plugging devices into it (most other extension cords & power strips are rated 15A). Other than that it is exactly as advertised.
