⚡ Energy drink

A standard 250ml or 500ml energy drink can or bottle will be confiscated at the checkpoint because it exceeds the 100ml liquid limit. You'll have to drink it, pour it out, or hand it over before passing through. Screeners treat canned energy drinks exactly like any other beverage.

The 100ml liquid rule applies in the US, UK, EU, Canada, Australia, and most other major aviation systems, so the restriction is nearly universal. Some airports with dedicated liquid scanners have temporarily relaxed enforcement for sealed commercial drinks, but you cannot count on this — stick to 100ml or less to be safe.

A 100ml or smaller energy drink that fits in your quart-sized clear bag should pass through without issue. Screeners are looking for containers that exceed 100ml, not the drink type itself. Just make sure the container's printed volume is 100ml or less and it's placed in your liquids bag like any other drink.

The simplest approach is to buy full-size cans after you clear security at the departure airport. Alternatively, pack full-size cans in your checked baggage, or bring only travel-size 100ml pouches in your liquids bag if you need something before the gate.
