Smaller is good if it doesn't mean something else will be sacrificed.
I think it's impossible to build a 3.0A charger that's as tiny as a 0.1A charger.
While not claiming I have seen every charger on the planet I have yet to find the tiny and powerful combination.
Most things are a tradeoff. Everyone wants a 26,000mAh powerbank that has the size of 2,600 powerbank.
I just hope Anker also keeps selling chargers for people that want lots of power out of lots of ports.
