If by “pass through”, you specifically mean being able to use a battery operated vaporizer while the internal battery needs to be recharged as it hits the low voltage cutoff determined by the power management setting (3-3.2 volts approx.)
In my personal use case, NO.
I like to use my wireless battery operated devices, as designed. If I forget to charge it, my fault.
Fortunately for me, I have others, most have swappable batteries, or if at home, a desktop, wall powered.
I can understand that some value this feature, but I’ve never had to use it. I’m sure many may disagree, but that’s my own opinion.
You’re welcome!
