The HyperJuice MBP 1.5-222 MacBook power bank battery is OK, though the USB-C Magic Box V2 is rubbish and a waste of money.
It stopped working and was replaced under warranty on two occasions in the same year.
Whatever electronic parts used or circuit design is not good.
A simple fix is to use a 100W car cigarette port USB C charger to make an adaptor for my MacBook.
The 100W car cigarette port USB C charger does get a bit warm when using.
This is normal as it does get warm when using it in the car on a 16 MB Pro
Link for the car cigarette port USB C charger. DON'T BUY, IT'S FAKE.
Update 1
After checking the watt output in my Macbook.
I now see that this aliexpress 100watt car USB-C charger from china is FAKE!
It outputs 45watts and not 100watts as advertised.
I will now try to source a genuine 100watt car USB-C charger.
Update 2
After some search I found a car usb c charger that outputs 87W when charging a 16 inch MacBook Pro.
Photos of the quick fix below.
