Any charger is going to me limited to it max amps. For example with my 1010 I can charge at 10 AMPS but the general rule is to only charge at 1C. So for a 2200 mah pack that would be 2.2 amps. Any of the chargers mentioned should be able to do that and they all will take the exact same amount of time to do it. You can charge at more amps as fast as you like but your packs will not last long and could possibly catch fire. That is on you.

You can charge multi batteries (again up to the max AMP delivery of the charger) but I would not do it unless you have multiple balancers. (See below for example)
