I bought some Chiwanese extension cord ends from a US source
recently
and was seriously disappointed. The connectors were neither marked
nor
color coded (unsafe for the normal DIYer), and one of the screws
stripped out as I tightened the shell together evenly around the
plug.
Amazon gave my money back.
The last sets were Chiwanese from HF and worked great.


Before putting the Fluke away I measured the voltage drop of 10.0A DC
through a 50' 14 AWG HF extension cord I just bought, in case I would
be risking a fire by running an air compressor on it.

The spec for 14 AWG is 2.5 ohms per 1000', so 100' should drop 2.5V at
10A. It measured 2.78V which isn't far off and includes the loopback
end contact resistances.
