Not a bad price on this power bank if you're after something with a large capacity and don't need the fastest charging available.
This one features 18W USB-PD fast charging via USB-C, Quick Charge 3.0 via the blue USB port and 5V/2.1A via the white USB port. For recharging it has USB-PD 18W via USB-C, QC 3.0 via Micro USB and 5V/2.1A via Lightning.

While this power bank exceeds 100Wh it's still possible to take it onboard with airline approval. Last time I checked Qantas/Jetstar require approval via email and Virgin asks you to declare it at check in. Refer to other airline's dangerous goods pages to see their policies.
Just an extra hassle getting approval for a 100WH powerbank when you can bring 2 of 20,000mAh ones no need for getting approval.
