It’s just a theory based off of my own experience, but if that’s the issue, it kinda depends on how large the capacitors are and what kind of capacity they’re capable of holding.
If it is the issue, I’d expect it to take like 5 minutes for it to discharge completely, but that’s just a guess. If everything is already out of its usual place, you could probably test it if you’re curious enough.
I use a Drevo Joyeuse for travel because it’s very low profile and wired/wireless
Drevo is out of business though :(
