Charges different rates (5)

I believe the answer is:

tears

'charges' is the definition.
('tear' can be a synonym of 'charge')

'different rates' is the wordplay.
'different' indicates an anagram.
'rates' with letters rearranged gives 'TEARS'.

(Other definitions for tears that I've seen before include "exuding drops" , "Signs of unhappiness" , "Lacrimal drops" , "emotional reaction!" , "Moves very quickly" .)

I've seen this clue in the Evening Standard.
