Will this work as a "dummy battery" with a reserve charge? I.e. passthrough keeps it topped off at 100%?

Dear Friend, Thanks for inquiry, Sorry, it cannot work as a dummy battery. If you need a dummy battery, we recommend you to see SmallRig dummy battery Asin:B0C85QN1SD, B0C85VJ1BVSincerely, SmallRig Customer Service

Can you charge the battery while its in the camera being used?

Dear Friend, Thanks for inquiry. We don't recommend using it this way. Sincerely, SmallRig Customer Service

do these charge other things via usb? like a powerbank as well?

No, the USB-C port does not output power. In response to your question, I attempted to charge several devices from the USB-C port on the camera battery. I tried this with a USB-C to Lightning cable and a USB-C to USB-C cable. None of those devices began to charge. I verified that these devices all accepted a charge when plugged into power sources with these same cables. The SmallRig battery that I used for this showed a 99% state of charge.
