So "true" pass through means that it works even with no batteries installed; but since we can't remove the batteries, it's a non issue, imo.
It's an issue if you care about the longevity and performance of your batteries. You will get "less sessions" per charge rather quickly if you are ignorant of healthy battery management practices. You may not care, but battery replacements aren't very cheap from S&B.
What is important is that even if the batteries are completely drained to zero, you can plug in and vape immediately, and they will charge from zero to full while you vape! That's "pass through" enough for me! It feels and acts just like a desktop.
Again, see above.
You don't have to even think or be careful, imo. Charge it up and down, micro or macro, it doesn't matter.
Maybe not to you, but again see above. The Mighty is not an inexpensive device, and battery replacements cost a fortune for this device IMO.
I saw it advertised too about pass through nevermind im going to just do it and have 2x bowls because wastage should not dictate a purchase.
Well with that rationale, you probably shouldn't care about wasting herb as you are concerned about?
Anyways, good luck with whatever you decide to do!
