I don't think the Vision Spinners with a port is a strict passthru; it's just for onboard charging (instead of a 510 charger) but it does have an internal battery, so you can vape and charge at the same time. Though some people don't recommend that.
I'll cast my vote for the Pico as well. It's main draw is it's small size but still pretty lightweight (with 18650 battery installed).
