Visualizing: AWG Explained: Why Thickness Matters
In the world of cables, a higher number means a thinner wire.
The Math of Resistance
A 28 AWG wire is much thinner than a 24 AWG wire. Thinner wires have higher electrical resistance. Higher resistance means more energy is lost as heat instead of reaching your device.
Why it matters for charging
If you use a long, thin (high AWG) cable to charge at 100W, the voltage drop might be so high that the device refuses to charge or charges at a snail's pace. Look for 'Low AWG' or 'Thick Gauge' for long power runs.
