When legitimate authority focuses attention on charger of malic 18W USB PD, the apple is however after congress of WWDC 2018 developer go up sadly wore charger of a 30W USB PD. Meanwhile, original 29W USB PD also is fallen to wear, that is to say this 30W charger replaced original 29W charger.

Comparative discovery, these two charger differ besides model, parameter and crust workmanship besides, product function also has very big difference, the compatibility that waits to mobile phone, mobile power source for instance, the output voltage when charging to new fund MacBook somewhat difference.

Undertake a detailed contrast to the interior of these two charger today, make everybody right the waits for a respect with makings, charge for the making of sth. difference of these two charger has a more clear knowledge.

Left is new fund 30W, right is old money 29W. Both dimension size agrees completely, only appreciably distinguishs the appearance. Main distinction depends on: Archives of outlet of crust, interface, AC, voltage wait. The crust of right 29W is an organic whole, and adapter of 30W of left new fund is by two solder together partly. In addition, USB-C interface also has appreciably distinction.

The model of 0W is A1882, output norms parameter is 5V3A, 9V3A, 15V2A, 20V1.5A; And the model of 29W is A1540, output norms parameter is 5.2V2.4A, 14.5V2.0A, only 2 archives. Above is this two paragraph charger basically distinguish in apparent, the interior that sees two charger next uses makings and do manual work.
