Like regular Redmi smartphones, Redmi Note 12 Explorer Edition still has a unique packaging
The included accessories are quite complete, including 210W fast charger, USB-C cable, transparent carrying case and user manual.
Quick review of some hardware parameters of Redmi Note 12 Explorer: The device is based on the Redmi Note 12 Pro + version, equipped with a 6.67-inch OLED screen, 120Hz refresh rate, Dimensity 1080 chipset, 200MP main camera, 4300mAh battery and has 210W. fast charging
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
The weight of the charger is extremely heavy, about 220 grams, almost as heavy as an iPhone 14 Pro Max
Comparing Xiaomi 210W charger and Apple’s 140W charger, the overall size of Xiaomi charger is much smaller
Using the POWER-Z KM003C support accessory to measure the USB-C port of the charger shows that the charger supports 3 fast charging technologies QC 3.0, PD 3.0 and Xiaomi’s own fast charging standard.
With PD 3.0 standard, the charger supports 4 fixed voltage sets of 5V3A, 9V3A, 15V3A and 20V3.25A (up to 65W), while with PPS standard it is 3.6V-11V10A, 3.6-17V10.5A and 3.6- 20V10.5A (max 210W)
The included USB-C cable can provide a maximum amperage of 10.5A. This cable has been upgraded by Xiaomi quite a lot compared to the previous 6A cable, increasing the number of internal cores while the cross-sectional diameter is almost unchanged.
The USB-C head is designed with special pins, when the pins are properly contacted with the required output, the fast charging power will be activated and can transmit up to 210W.
Use POWER-Z KM002C to measure this cable, with eMarker chip, fast charging up to 20V5A 100W, transmission protocol is only USB 2.0, suitable for small file transfer
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.
Working principle of 210W fast charging on Redmi Note 12 Explorer: Xiaomi uses 3 charge management chips to convert charging power
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.
Using the 210W fast charger included with the Redmi Note 12 Explorer, the chongdiantou page measured the maximum power received by the device as 182.43W (17.64V 10.34A)
In the full battery charge test, the Redmi Note 12 Explorer reached the highest capacity of 184.85W (17.86V 10.35A). Specifically, in the first 3 seconds of plugging in the charger, the device received a capacity of 180W, from the 3rd to 28th the charging capacity peaked at 184.85W, the 32nd to 47th seconds the power decreased to 151W, the 49th. second. . power range from 128W – 139W for up to 4 minutes 20 seconds; after 4 minutes 45 seconds the power drops to 115W, after 6 minutes 35 seconds the power drops to 78W and after 8 minutes and 6 seconds the power continues to decrease until fully charged.
Graph of 100% battery charge time: it only takes about 10 minutes and 10 seconds, about a minute slower than the theoretical time, but that’s too fast. The graph also shows that the device charges 36% after 2 minutes of charging, 68W after 5 minutes of charging
The test shows that in 10 minutes of charging, the temperature of the hottest area of the device is up to 43.3 degrees Celsius at the 5th minute of plugging in.
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. .
