i am seeking forward to an auto charger version of this comparison. many thanks for the great comprehensive data!
Just one intriguing design and style aspect is the filter capacitors fit through the Slice-out holes in the secondary circuit board, allowing the large filter capacitors to fit inside the charger. Extra comments on this information are at Hacker Information and reddit. Many thanks for checking out!
Another thing I'd be interested to determine can be how this maps on to the eu insistence that everything use a micro-usb cable, so that individuals can minimise the amount of charges they possess.
