I do not know anything about chargers, so far as I can tell, they are either very simple or quite sophisticated; that is the sum total of my technical knowledge.
This product feels beautifully made. It obviously uses sophisticated technology to adjust the power delivery to meet the ideal requirements of the battery being charged.
The folding plug pins are very convenient and operate beautifully. excellently engineered, as the whole product seems to be.
I am delighted with it so far and am thinking about buying another, and will also consider an in-car charger if Anker makes one.
