Very cool - amazing that you can fit something that small in your pocket and it can also power a full size monitor & keyboard. It sounds like the Hackberry Pi is a great fit for your use case. I hadn’t considered using the Bumble Berry like that, but now that you mention it, I might try it out like that next time I travel.

It would be nice to have the beefier Pi 5 on Bumble Berry for the rare times that I need a GUI. I mostly use terminal on this device so it’s usually not a problem, but when I do have to use the full GUI I find the 3b+ annoyingly slow.

I briefly tested the Bumble Berry battery with a Pi 500 and although I got an error message saying that the power supply is not capable of supplying 5A, it seemed to run just fine. The battery is rated to 3A, and streaming full screen video on a 4K screen seemed to draw only about 1A (measured by a usb-c pass-thru dongle). However, I did not push the Pi 5 to its limits and I haven’t used it for an extended amount of time so I can’t confidently say how well it would work.

If you’re willing to pay the extra cash and want a smaller form factor it sounds like Hackberry is definitely the way to go.
