Vessel one charged with small drinks (7)

I believe the answer is:

potions

'drinks' is the definition.
(potion is a kind of drink)

'vessel one charged with small' is the wordplay.
'vessel' becomes 'pot' (type of container).
'one charged' becomes 'ion' (type of charged particle).
'with' says to put letters next to each other.
'small' becomes 's' (abbreviation - e.g. clothes size).
'pot'+'ion'+'s'='POTIONS'

I've seen this clue in The Independent.
