Recently, we got a classic power bank from ZMI, ZMI No. 20. It is equipped with a 25000 mAh battery pack and supports up to 100W PD input and output. So, it can fast charge your laptop and itself. Two USB-C ports and a USB-A ports allow you to charge multiple devices at the same time.
Let's try to charge 100 different devices with it today and see if it can pass the ChargerLAB Compatibility 100 Test.
