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.
