I'm a little stuck... Click here to teach me more about this clue!

'fee' is the definition.
(I've seen this in another clue)

I can't explain the rest of the clue.

(Other definitions for charge that I've seen before include "Formally accuse (someone)" , "Set price or mount onslaught" , "Accuse; load, fill" , "Lord Cardigan's order to his brigade" , "The price asked for goods or services" .)

I've seen this clue in the Sydney Morning Herald.
