From what I have seen the barrel connector (3.5mm OD, 1.35mm ID) is also known as a "Type-H" connector.
The most common DC extension leads use the bigger "Arduino/laptop" (5.5mm OD, 2.1mm ID) connectors.
You can get big-to-small barrel adapters and small-to-big but that would add a lot of connections between charger and Pinebook
Just the single ste up/down adapter. That's not bad. My travel power setup is pretty similar (primary USB cord that uses barrel adapters for the device end) and it works very well (even gives me a 90 degree bend at the PBP, so the power cord does not jut out the side.) Now if a single adapter isn't an option, and multiple are required, I agree that's too much and may not be worth it.
Decided to look up the conversion using the common numbers given, and I'd say this is worth the price for @dumetrulo to at least try if it allows them to be able to reuse an existing power supply:
