Regarding ChargerLAB's products:

I have an HP Zbook G1a laptop that uses 140W USB PD charging. However, except for the HP charger, I have not found a charger or cable pair that works. After a while they start cycling charging on and off. Under heavy load that happens almost immediately. Under light loads it might take hours.

Is there a ChargerLAB product that can explain what exactly is going on between the computer and the charger?

I have used Anker, Insignia and some random USB-C PD chargers and cables rated for 100-140-240W from various vendors.
