💻 USB hub

A USB hub will not be confiscated — it is a fully permitted electronic device with no restrictions. If a screener flags your bag, it's likely because the hub's multiple ports and circuitboard are obscured by other items in the X-ray image. Pulling it out for a quick visual inspection is all that's needed, and it will be cleared immediately.

USB hubs face no restrictions in any major aviation system globally. Unlike items with lithium batteries, a standard passive USB hub has no hazardous components, so it's treated as ordinary electronics everywhere. There are no regions that require special declaration or have additional rules for USB hubs.

Generally no — only laptops and large electronics are required to be removed from bags for separate X-ray screening at most checkpoints. A USB hub can stay in your bag. At stricter checkpoints or in countries with enhanced electronics screening, you may be asked to remove all electronics, but this is at the screener's discretion.

Either option is fine from a rules perspective — there are no restrictions either way. Carry-on is generally preferable for electronics to protect them from rough baggage handling, but a compact USB hub is durable enough for checked baggage if you need to save carry-on space.
