Don't forget about the wiring in the house. The circuit length starts at the circuit breaker in the panel and there could easily be near or more than 100' of wiring before it reaches the receptacle. I recommend only using 12awg extension cords on 15amp circuits per the "100 Feet Rule".
A 16awg extension cord is a hard pass and not recommended. 16awg is even smaller than the 14awg conductors used in 15amp circuits in the home and would technically downgrade that circuit at the end of the 16awg extension cord to 10amps. That's before even factoring in the 100 feet rule.

not too bad, A 16-gauge wire can safely handle 13 amps
is can handle one 1500 watt portable heater and most portable AC unit.
Not all portable A/C units. The larger versions (above 12,000 BTU) could easily draw more than 13A
A 1500watt portable heater would just barely be under the 13A limit

Short cables, less than 50', might allow for a 13 amp load. Over 50', with 16 gauge wire, is too thin and can only be trusted with 10 amp loads.
This is based on the UL general use circuit ampacity chart.
Me personally - I'm not risking it. I saw heavy duty and got excited about some use cases I have. Like I couldn't place a compressor where I wanted because an outlet was "just" too far.

Some good points made here: I am looking to get these for low powered electronics that terminate on a UPS like routers, cameras etc...mostly 12V devices that have large power supplies clogging up the UPS ports. So I think if the use case is such as this, then 16 AWG should be ok, but as stated by others, I would not risk these on microwaves and heaters. Soon as I get them, I will lable them as "Low Power" to make sure they are not used elsewhere.

Interesting.. safe to say most of the Ethernet 5/5e/6/6e running in our house is less than 100m too? Not related to electrical but maybe an EE major can chime in…

These are lamp cords with extension cord skins, seems like trouble for folks without awareness of what AWG means.
Nice idea, but 16 AWG is a hard pass for me on extension cords. Anything I might use this for I simply put a power strip on the outlet before obstructing it.

100m is the distance limit for UTP Ethernet.

Not sure what everyone is arguing about. The title literally states "16 AWG 13A". If you're driving 15A equipment, this is not for you. Buy a heavier cord. For most electronic devices, you are fine. If you're that worried about it, buy an inline amp/watt meter or insert a surge protector inline.

Would like a couple different 3 pin various Short lengths with factory ends on them.
Could have use one of these last week, but just substituted a power strip as it was the closest part on hand that matched the need.
