Voltage/current drop using alligator clips

[the evil twin]

Turtle is correct of course... so just to be absolutely clear now we know the max load current is only 10 amps...

If you are dropping more than .1 volts across the Adapter and Andersons at 10 amps you have issues.
If your voltmeter goes to two decimal places I would want it to be much less than that IE less than .05 volts

Trying not be confusing here but the difference is the way the voltmeter will round out if it only has 1 decimal place on the display
12.66 actual will display as 12.7 and 12.64 actual will display as 12.6 so the drop is actually only 0.02 but displays as 0.1

Thanks gents, yeah that was my concern with start up, I'll check it out...

At that distance you shouldn't have an issue. If the 12v device is one of the newer large portable air compressors, then cable the size of jumper leads would be required to cope with voltage loss and heat, as these compressors pull lots of amps. If this is your use, ensure you are also running the vehicle when used.

Just went and checked my extension lead, Anderson one end clips the other, and yes there is a 0.01v drop over its 3m length. Use it as an extension lead for my solar panel when needed.
