Hello
Not sure which is the power of Original Supply. Your Powerbank will not delivery enough power I believe.

you have 5V 2A, Power = Voltage x Current, so you have 10W delivery.

When you use Step Up to 12V, you should still keep the 10W,

10W = 12 x Current , in the end with this setup you will delivery only 0,8A of current on Laptop, which I believe it-s not enough to charge it.

Original charger delivers 12V at 2A, so 24W. In order for powerbank to provide enough power you would need a supply of 5V at 4.8A.

Better setup would be to get a powerbank with USB-C output that delivers at least 2A at 12V, and use a converter from USB-C to the plug of Herobook charger.
