THE PRACTICAL PERSPECTIVE
Check the device’s charging requirements and choose a suitably rated USB-C to USB-C cable. If a laptop needs the higher output, plan to use USB-C alone. Treat nominal capacity as a battery specification rather than a promise of a fixed number of complete phone charges.
Confirm the required charging profile, cable and suitable wall charger. For travel, check the carrier’s current battery rules directly. Keep the stated 74Wh figure available when checking those rules.
