As far as I know, the Pinebook Pro is not advertised as developer hardware. Only Ayufan, MrFixIT, Luke and maybe others got developer hardware way over a year ago.

At a maximum, it's still community development hardware.  It's possible to use one as a daily driver, but I wouldn't recommend that for someone who was not already a reasonably skilled Linux admin with some hardware experience.  There are still plenty of rough edges, like the latest wifi firmware screwing up the wireless connectivity, the blend of things required for deep sleep, and sound not working reliably after that.

I put things like the charging behavior in the "It's still beta" category.  The right answer, IMO, would be USB-C power delivery hardware, but that's not what the unit has.

If I load the system up hard, I can get 3.5A out of the battery at around 3.8V - that's 13.5W.  It should hold that on the barrel plug, but it's observably not - or it heats up and can't keep up.  Not sure which.

There's nothing wrong with that - it's just a design decision they made.  But I wouldn't give a PBP to a non-technical friend yet for anything resembling regular use.
Thank you for the reply and reasserting my perspective. I forgot what I was getting myself into. Aside from rough edges this thing is amazing! I plan on giving my initial impressions in the proper thread. Sorry it took a while to respond. Been dealing with a lot of health issues with family members. I will be making the change to have it run directly off of the barrel plug and unplugging the battery when I get some downtime to tinker some more. I WILL make this my daily driver come hell or high water. Big Grin

Last year, there was an power issue. I did measurements.

This year, the situation is different. Even under the slightest load, the battery takes over. This is also what Upokupo experiences ("writing this post in firefox").

I'm not sure what changed? New kernel (4.x vs 5.x)? New device tree tweaks? "Age"? What else?

Please try it out. It would be interesting to see if the laptop stays up. Maybe it shuts down as it can not fall back to the battery.
I will do that when I find some downtime to tinker with it some more and post some results. I still love this thing and having a blast with it.
