Why limit yourself to charging a single device when multiple ones can be recharged simultaneously? A power bank with multiple USB ports is like a banquet, offering a spread of charging options for your hungry devices. Envision a power bank with a USB-C port and USB-A ports inviting your smartphone, tablet, and headphones to plug in and rejuvenate simultaneously.
