I think the power connector on my Alpicool is an IEC C11. Other brands such  
as ARB appear to use the same notched rectangular plug.

The voltmeter on my T60 showed 0.3-0.4V less than the power supply I used to  
confirm its low voltage shutoff, then after it shut down the voltage rose to  
match the supply so the IR drop was in the cord and connectors. I couldn't  
find a separate C11 to wire but 3/16" brass tubing squeezed to 0.080" (2mm)  
made good substitute sockets on a 12AWG cord with Anderson PP45s on the  
other end. PP45s are the common 12V connector for amateur radio and  
excellent for battery wiring because all unplugged connectors have shielded
