Streamlining the battery charging process, the Hasselblad Battery Charging Hub contains dual slots that support the simultaneous charging of two batteries. An integrated USB Type-C connector supports mains power via an included power supply or from common external USB battery banks (sold separately). Front-facing LEDs indicate status and capacity when charging, or users can use the Battery Charging Hub to check battery levels simply by inserting a battery and pressing a single button. The Battery Charging Hub supports both first-generation 3200mAh X System batteries and current 3400mAh batteries, the latter of which support quick-charging up to 25% faster than the former. This equates to a completely replenished single battery in 2 hours 18 minutes, or dual batteries in 2 hours 48 minutes. First-generation 3200mAh batteries recharge completely in approximately 3 hours. Complete charging is indicated by an audible chime.
