The OM System SBCX1 is a kit coming with one BLX1 Battery and the BCX1 Battery charger. This is the perfect accessory for your OM1 as you get a second battery and the charger to charge both batteries in roughly 150 minutes. As it is equipped with USBC port you either simply use the F7AC, which comes with your OM1, or any other USBC mains adapter to power it.
