What is Pass-Through Charging?
Pass-through charging makes it possible for a power bank to charge itself and charge other devices at the same time.
Pass-Through Charging Advantages
Due to its two-fold rotational-symmetrical connector, a USB cable can be inserted either way, so you don't have to figure out which end goes where, eliminating the frustrations of earlier USB ports. USB-C is compatible with many of the latest laptops, phones, and tablets. And given time, USB-C will likely be adopted by pretty much everything that currently uses the older, larger USB connector. With increased data-transfer speeds comes the ability to send simultaneous video signals and power streams. USB-C’s Alternate Mode for video enables adapters to output video from the same USB-C port to HDMI, DisplayPort, and other types of video connectors on displays, TVs, and projectors. What’s more, USB-C supports the USB Power Delivery specification. USB PD can deliver up to 100 Watts of power, more than six times what USB 3.1 is capable of. This opens up the potential for laptop-powered projectors based on USB-C.
