About the same difference as there is between Coke and Pepsi. Quite a few products use both names. For instance:

Technically speaking a true trickle charger can have a lower ampere rating, as it's only designed to provide enough current to account for the natural discharge rate of a battery with no load. Today that would apply mainly to a battery left sitting on a bench, or one in a tractor or boat that has no load on the battery when not in use. Modern cars never have no load on the battery, there's always something running that will drain a battery at a faster rate than the battery's own normal discharge over time. With a true trickle charger automatic shut-off isn't necessary, as the low current delivery is always offset by the inherent discharging of the battery. Such devices are very rare today, as electronic regulation is very inexpensive and therefore found in virtually all chargers whatever their current capacity.
