"Much" refers to something not countable, like "much more milk", and is used without plural, "liter" is countable such that you could say "many more liters of milk" (note the plural of liter). So while I'd say the latter is more correct according to grammatical rules, if both are common, both can be considered correct, as rules are often rewritten to adapt to the way the English language is used.

The EU doesn't have to mandate a new connector when something new comes up, it just has to be an open standard, ANY open standard. This is miles better for everyone.
