What would happen if I charged the laptop with a PD 100w charger and it barrel jack charger Simultaneously? For my model, it is Helios Neo 16, 13500HX, RTX-4050.

    Hi @Nayeon16 In theory, there wouldn't be a problem because USB Power Delivery is a smart protocol and won't charge from two sources, but I don't recommend trying it.
    If you think doing the rest will make the charge faster, that won't happen.

    Your Helios Neo 16 laptop prioritizes one charging source at a time, so using both a PD 100W charger and the barrel jack charger simultaneously is not recommended. The laptop will likely default to the barrel jack charger, and using both chargers could lead to power conflicts, charging instability, or excess heat buildup. To avoid risks, it's best to use only one charger at a time.

    IMO no issues, USB Power Delivery (PD) is a smart protocol that prioritizes the highest available power source—typically the barrel jack adapter in your case. This means your PHN16-7X will default to the power adapter for charging, while the USB-C charger may behave more like a backup or secondary power input.
