The gap between Xiaomi 27W and 30W is still relatively large. 30W is a charge pump fast charge, can be full of blood for 30W output. 27W relatively to stretch a little, full blood output time is relatively short.
Xiaomi's 27w actual charging efficiency and time, and the 18w mutual agreement gap is not large, full of only a few minutes of the gap. Individuals can be approximated to the 18w level. Charge 2000mAh in half an hour.
The main force of Red rice in 2020 is 33w, and half an hour is rushed into 3000mAh.
The difference is not very big, that is, a maximum support of 30 watts, a maximum support of 27 watts, in the charging process, is not continuous maximum power work, I hope to help you!
