If just the pull tab has come off but the zip slider itself is intact, a small loop of paracord, a keyring, or even a sturdy loop of wire threaded through the slider’s hole restores enough grip to operate the zip normally — a genuinely simple, low-cost fix that takes a couple of minutes.
If the slider itself is cracked, bent, or no longer grips the zip teeth properly even with a working pull attached, that’s a more involved repair — a replacement slider needs to be fitted onto the existing zip track, which is a job most local tailors, shoe repair shops or dedicated luggage repair services can do, though it’s not typically a manufacturer-supplied spare part in the way a wheel or handle often is.
Avoid forcing a zip with a compromised slider, which can damage the teeth themselves and turn a simple slider replacement into a full zip track replacement — a meaningfully bigger and more expensive repair.
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.
