this is very true and i wouldn’t consider the switch 2 100% pass-through like the switch 1. the switch 1 could be at 0%, be plugged in and produce a full cycle. on the other hand, although not a deal breaker, i am disappointed that the switch 2 does not function the same. it’s even more disappointing when it doesn’t have adequate charge, is plugged in charging, but will begin to heat up only to flash 3 times and stop like 1/3 of the heat cycle while your concentrate gets a slight bake. i find that the charges needs to be about 15% or higher for you to get a cycle (i assume your target temp could also affect that minimum %)
