20W C mouth fast charging version and 27W 3A mouth version are going to win a lot, but the 27W version is 69 yuan in the market, and the 20W crowdfunding period is 59 yuan (officially sold is 69), and the new product is cost-effective.
In addition, compared with the single A-port maximum 27W plugboard launched by Xiaomi last year, the new single C-port 20W is only nominal lower by 7W, and the actual test comparison, the fast charge speed and full time are not significantly extended (the key depends on the matching of different models of the protocol), and the increasingly mainstream C to C line can be used. It also has the same small size as the base version (the 27W version is fatter, longer and thicker by a few millimeters), so the two are in equal measure.
Electronics are still new, not used.
