🔊 Portable speaker

Most portable speakers have batteries well under 100Wh and pass through without any issue. If your speaker has a battery above 100Wh, the airline may stop you at the gate and require approval before you board. Speakers themselves are never confiscated for their battery alone — the airline will either grant approval or ask you to leave it.

Most regions follow the same approach: speakers are fine in both carry-on and checked baggage. However, because lithium-battery devices can present a fire risk in an unmonitored cargo hold, aviation authorities worldwide — including in the EU and Australia — recommend keeping battery-powered speakers in carry-on where a fire can be detected and managed.

Routine gate checks for speaker battery capacity are rare unless the device is visibly large or the battery label is prominently marked above 100Wh. If stopped, you can check the manufacturer's spec sheet on your phone to confirm capacity. Airline staff have discretion to approve devices between 100Wh and 160Wh.

Carry-on is always the better choice for a speaker with a built-in lithium battery, both to protect it from baggage handler damage and to comply with the general recommendation that lithium-battery devices travel in the cabin. If size forces you to check it, make sure the battery is below 100Wh and the power is fully switched off.
