SN1 Chargers:

To play SN2 select a Bot, a Battery and fuse them together with a charge to turn on the yield for Season 2!

Your Beep Boop charger turned on the power of your batteries in SN1 (obviously). Each charger can only charge one battery, so make sure you stock up while supplies last... there was many other surprise utilitys as this is the only paid mint in our ecosystem for SN1.
