That would be 258.
VD on a 13A load would be 13 * .258 = 3.35V

Power=I^2*R. R=129*2, or 0.258 ohm. At 15 amps, the power loss over 50 feet is 58 watts.
In other words, pretty insignificant.
Should work just fine for that low load charger. And the intermittent saw.
Only draws 13 amps under full load. Just feed the saw in slowly, so it doesn't bog down too much. Slow cuts will take less amperage.
