[aawp box=”B07H5T9J4L” description=”none” template=”horizontal”]

The first portable charger on our list is the ROMOSS 30000mAh Power Bank Sense 8+. It is a large, high-capacity power bank with 5 ports. Among them, 3 are input ports, and the rest are output ports. That means one port supports both input and output. The ports are –

1 micro-USB input port
Single Lightning USB input port
1 USB Type C input and output port
2 USB Type-A output ports

The bi-directional port and a USB Type-A port support Quick Charge 3.0. For instance, the USB C port can charge up to 12V.
