In 4 versions of Redmi Note 12 introduced by Xiaomi on October 27, Xiaomi has marked a new milestone in fast charging technology on smartphones when equipping with Xiaomi’s 210W fast charging fast charging for Redmi Note 12 Explorer Edition.
According to Xiaomi’s announcement, with the 210W fast charger and the included charging cable, it only takes you 9 minutes to fully charge the 4300mAh battery to 100%. This is the fastest battery charge time on the market.
Chongdiantou site recently performed a test to check the fast charging speed of Redmi Note 12 Explorer Edition as well as whether the device heats up during charging. Let’s analyze it with chusa.info below!
This is Xiaomi’s new 210W fast charger. With a large capacity, it is understandable that the charger has a large size. In this version, Xiaomi has switched to using a USB-C port instead of a USB-A port on the charger body
The size of the charger is 67.4 x 64.69 x 29.79mm, the power density reaches 1.62W / cm³
210W power. fast charging principle
According to the chongdiantou site, Xiaomi applies a super-fast charging architecture by using 3 highly efficient charge management chips to reach a maximum capacity of 210W. The input oil line (20V 10.5A) will be divided into 3 different channels, the voltage and current of each channel is 20W 3.5A, after going through the management chip, the voltage and current are raised to 10V. 7A, then these 3 channels are combined and produce a capacity of 210W, divided by 2 independent battery cells, in which each cell receives a capacity of 105W (5V 21A). The total capacity now when adding 2 battery cells is 210W.
Due to hardware limitations, Xiaomi is forced to divide the battery capacity of the device into 2 battery cells, helping to disperse heat sources and maximize charging time at high capacity.
It can be seen that with a capacity of 210W, Xiaomi has set a new record for fast charging on smartphones when it only takes 10 minutes to fully charge 100% of the battery of the device. Notably, the 210W power does not appear on Xiaomi’s high-end smartphone line, but on the mid-range Redmi Note series, which has an accessible price.
Before that, Xiaomi also set a new record for fast charging when equipping Redmi Note 11 Pro + 120W charger, taking just over 20 minutes to fully charge the device’s battery. 120W capacity is currently equipped on Xiaomi 12 Pro, 12S Pro and many other Xiaomi smartphones… In the near future, Xiaomi’s flagship lines will also soon “update” 210W charging capacity.
Redmi Note 12 starts at 1199 yuan, equivalent to 4.1 million VND for the Redmi Note 12 version. The high-end Explorer version with 200MP camera and 210W fast charging also costs only 2399 yuan, equivalent to 8.2 million dong. .
