The USB-C port supports Power Delivery (PD) and Quick Charge (QC) 3.0 and can be used to charge both the power bank and a mobile phone. Pass-through is also supported, which means you can charge a mobile phone via the power bank while the power bank itself is charged via the USB-C port.
Unfortunately, we cannot obtain the 2nd generation from our suppliers at the moment, which is why we cannot tell you if and when the item will be available.
