Battery powering a Phil Jones Double Four

Here I am in December 2025, at the end of this thread, looking for a battery pack that will work with PJB B-75. The Poweradd that worked with it died. I'd like something similar that I can just plug in, but it looks like the newer versions all come with type C in and out and I'd need an adapter to the PJB DC "in." I can manage that, but would love to see recommendations for an all-inclusive set-up that actually works for you in real life. I am playing mostly in acoustic jam settings and only need a couple of hours--low and slow.
Wish I could help, but I've the D4+/USB-C power?...

Do you have the earlier model with the barrel plug instead of the USB? It may be nerdy but you can get a 20v "Power Wheel" adapter and a couple barrel connecter "pig tails".

I just use a USB-C to barrel jack cable. Works great.

I thought about getting a bigger battery, but I think I would rather have two batteries. So I will probably order a second battery and cable at some point.
