Full answer

HP’s own QuickSpecs list USB Type-C adapters for the slim ZBook mobile workstations: 65 W on ZBook Firefly 14 G11 and G11 A, a 100 W Slim USB-C adapter that HP says is required when a Firefly 14 G11 has discrete graphics, 65 W / 100 W / 140 W USB-C on ZBook 8 G1i 14 (HP lists max operating power under 100 W with integrated graphics and under 140 W with discrete graphics), and a 140 W slim USB-C adapter on ZBook Ultra 14 G1a. Read the wattage printed on your lost brick first.

A 65W USB-C PD charger matches the 65 W bricks; 100W matches the 100 W Slim adapter. HP’s 140 W adapters use USB PD 3.1 at 28 V (HP’s 140W Slim adapter table lists 20V/100W and 28V/140W), so to get the full 140W from a third-party charger you need a 140W PD 3.1 charger and a 240W-rated USB-C cable; a 100W charger still runs and charges those laptops, just slower under heavy load. The ZBook Power 16 G11 A is different: HP ships a 150 W Slim Smart adapter on a separate power connector, so a USB-C charger is only a backup there — buy HP’s barrel brick for full performance. Sister HP pages: HP USB-C (EliteBook / ProBook / Envy) and HP Chromebook. Full method: how to pick.
