Practical caution
Choetech's narrative mentions USB-C output, while its detailed output table lists only USB-A; confirm the exact port behaviour before buying.

Buying checks for the United Kingdom
Single-port output: Use the fastest single USB-C port and its supported charging profiles—not the larger combined multi-port marketing figure. Cable and charger: Confirm the included cable rating and whether a wall charger is supplied. A 100W power bank cannot deliver 100W through a lower-rated cable. Comparable capacity: Compare watt-hours as well as mAh. Published mAh normally refers to internal cell voltage, while real device charging also loses energy in conversion. Travel and warranty: Check the airline's current battery rules, the exact model label and whether local warranty support applies to an imported unit.
Regional note
Confirm the exact model, USB protocol, cable and delivery terms before ordering.
