In recent times, there has been so much emphasis on the charging capacity of a smartphone. In addition to the phone charging capacity, the charger rating plays a major role. Without a high-power charger, a phone can not meet its maximum charging capacity. These high-power chargers are getting more expensive, the more reason why manufacturers should exclude them from the box. The Xiaomi 65W GaN charger was released at the beginning of last year. Although this charger is not the official charger of the Xiaomi Mi 11, it seems to be desirable.
The maximum charging capacity of the Xiaomi Mi 11 is 55W, thus the 65W GaN charger delivers effectively. The Xiaomi 55W GaN charger is the official charger of the Xiaomi Mi 11. However, because of the huge traffic that the Xiaomi 65W GaN charger is attracting, some users are confused. Why will most buyers prefer to buy the Xiaomi Mi 11 with the 65W GaN charger instead of the official 55W Gan charger?
Some believe that the Xiaomi 65W GaN charger is better than its 55W counterpart. Thus, this article looks at the detailed comparison of these two chargers. You will be the final judge of which is a better charger.
Xiaomi 65W GaN charger Vs 55W GaN charger – External comparison
Different from the appearance of smartphones, the appearance of chargers are relatively “monotonous”. This means that there is not much room for changing the appearance. The first thing to consider in the design is that it has to serve the purpose. Thus, looking at chargers generally, the differences are only in colour, body shape, and size.
Appearance
The Xiaomi 65W GaN charger has a minimalist design, with a PC flame-retardant white shell. It also has a very light gray silkscreen on the side with the words Xiaomi 65W. Its overall shape is slender or elongated with a simple design.

Dimension & Weight
The Xiaomi 65W GaN charger uses gallium nitride power devices to break through the technical barriers. It condenses the charger volume to 30.8 x 30.8 x 56.3mm and the power density is as high as 1.21W/cm. The power density exceeds one cubic centimeter and more than one-watt output, marking the coming of a new era. The Xiaomi 65W weighs only 82g, which is even lighter than some 30W chargers.
For the 55W GaN charger, the dimension is 52.58×41.85×28.34mm. The entire charger volume does not exceed 62.36cm. In terms of power density, according to the PD power of 50W, the power density is about 0.8W/cm. If we consider Xiaomi’s private agreement of 55W, the power density is about 0.88W/cm. The 55W charger weighs about 101.9g, which is heavier than the 65W above.
