The foam padding and fabric of a hip belt generally last for years of regular use before showing meaningful compression or wear, particularly on packs built with quality padding designed specifically for repeated load-bearing use rather than a basic budget fill.
The buckle is usually the part that fails first — the plastic clip mechanism takes repeated stress every time the belt is fastened and released, and after enough cycles the tabs can wear down, crack, or stop clicking securely closed. This is a more common failure point than the padding or webbing itself wearing out.
Most trekking-pack manufacturers, including Deuter and Osprey, sell replacement buckles and sometimes full hip belt assemblies as spare parts, which is worth checking before assuming a failed buckle means the whole pack needs replacing.
Check with your airline and read the label before you follow anything here. Lithium battery watt-hour limits, liquids allowances and lock policies differ by carrier and by country, and change over time — the figures published by the airline or security authority you are actually traveling with take precedence over anything written on this site. A power bank or spare battery is carried exactly as its manufacturer and your airline specify, never estimated. We report what is published — a watt-hour rating, a size limit, a lock's official recognition — and this site describes the equipment only: nothing here is a guarantee about what a specific checkpoint will allow on a specific day.
