All USB-C ports on Omnicharge products support USB Power Delivery. USB Power Delivery (or PD, for short) is a unified charging standard that can be used all across USB-C devices. Normally, each device is charged with its own adapter, but with USB-PD, one universal USB-C adapter will be able to power a wide variety of different devices including laptops, tablets, phones and more. USB PD uses voltage profiles that are standardized across PD compatible devices.
Not all USB-C devices use USB PD, but this is mostly a problem with older USB-C devices. Most modern USB-C devices are compatible with USB PD.
