Last weekend I ran into some issues on a long cook where I was using the Fireboard 10000mAh battery backup, and yet still ran out of power on the main Fireboard without it having "tapped into" the battery backup.
I've been working with Fireboard since, and shipped off my logs, which they're looking at, but in the meanwhile decided to do some experimentation on my own. I've found some interesting results.
I set up the fireboard in my office, attached to my fan, configured with a fully charged Fireboard and fully charged battery pack, attached with a cable between the big red USB-A port on the battery to the USB-C port on the fireboard. The Fireboard registered that it had 5V connection. I left the fan running all night (at 10 or 20% so it wasn't loud) and went to bed. The next morning, the 10000mAh battery had barely been touched, but the Fireboard was down to 62%.
Next night, I repeated the experiment, but this time used a cable with the USB-C at both ends to connect the fireboard and the battery backup. Fireboard device showed 12V attached. This time the experiment ran much longer...nearly 12 hours (I slept in) and when the Fireboard showed 96% charge, and the 10000mAh battery was around half.
So, it seems that the Fireboard performed more the way I would have expected, drawing power from the power cord before using its own battery, only when connected at 12V.
I don't know whether that's a glitch in my unit, or standard, or whether this would work for you, but if you're going to do a long cook on the FBX2D with the battery pack, it may be worth trying this experiment yourself.
Next step...going to try the same with AC connection and different USB cables/voltages. Hypothesis is that I'll get the same results The wall USB adapter should make it a difference only in voltage, i would think, but we'll see.
