Introduction
The RTK-251-1PowerBank3 is a 3cell (series connected) Li-ion battery power bank reference board having one USB
TM
Type-C
port. The USB Type-C port supports the Dual Role Power (DRP) Feature. When the power bank is in Sink
mode, the power bank requests 5, 9, 15, 20V which is supported by a USB Power Delivery (USB PD) provider such as
a USB PD AC adapter. When the power bank is in Source mode, as long as an installed battery has enough power
budget, it will supply 5, 9, 12, 15, 20V which is requested by a USB PD consumer product such as a Tablet, PC, or
smartphone.
The RTK-251-1PowerBank3 works as DRP device and automatically detects Power provider such as a USB PD AC
adapter and Power consumer such as a Tablet, PC, and smartphone that is connected to this board. Also, it changes own
power role depending on the remaining battery capacities. The battery remaining capacities are always displayed on
LEDs.
The RTK-251-1PowerBank3 board is USB-IF PD3.0 certified and the functions and capabilities are fixed in the setting
at that time.
