How to power the R4 Pro
The R4 Pro includes a 60W power adapter (12V-5A) and offers two ways to power it: a DC input port on the front and a Type-C 20V PD port located on the back. The DC option will probably be the most popular since it doesn’t get in the way of opening the case’s upper cover. That said, both options worked well for us.

The BPI team lists the No 42 as CR1220 but it’s important to note thier POS is wrong. The other thing, you mention the battery keeps certain boot options, while this is true for a PCs, it’s untrue for the BPI, the only function… Read more »
