I bought an AOC MiniLED monitor that was shipped from China. It came with a white power cable, but I also have a black cable whose connector fits the monitor, so I'm wondering whether they can be used interchangeably. The black ISHENG cable is marked 7A/125V, while the white HONGLIN cable is marked 10A/250V and has "60227 IEC 53 (RVV) 3×0.75mm² 300/500V" printed on its jacket. The black cable says "VCTF 3×0.75mm²" and is fitted with a US-style plug. I live in the Philippines, where household mains voltage is generally around 220V. The monitor itself is rated for 100–240V, 1.5A. Is the black cable suitable, or should I use the supplied white cable?

The white cable is the safer and simpler option. Its 300/500V jacket rating and 250V plug rating are appropriate for Philippine mains, and the monitor’s universal-input power supply does not need a voltage converter. Just make sure the outlet, plug, and cable are undamaged and that the monitor’s label really says 100–240V input.
The monitor’s 100–240V rating means it can operate on Philippine 220V mains, and the 0.75mm² conductors are more than adequate for a 1.5A monitor. However, the 7A/125V rating on the black cord’s plug means it isn’t the right choice for 220V operation unless the cable and plug are specifically certified for that voltage. Use the supplied white cable, or another properly rated local 250V power cord. The connector fitting physically does not make the cord electrically suitable.
The cord’s current rating is not the main concern here. A 7A cord could easily handle the monitor’s 1.5A load, but voltage and certification matter as well. Since the black cord is marked 125V and has a US plug, don’t use it directly on 220V mains. Use the included 250V-rated cable or a properly certified replacement with the correct plug for your outlet.
That’s why I was unsure—the black cord has the correct monitor-side connector, but its US-style plug and 125V marking aren’t appropriate for the 220V outlets here.
