In August 2020, Xiaomi released the Xiaomi 10 Supreme Commemorative Edition with 120W private protocol fast charging, which comes standard with a 120W USB-A Magic PD charger (model number: MDY-12-ED), setting the direction for the flagship fast charging of Xiaomi phones for the next few years. Xiaomi 120W system ultra-high performance mainly for cell phones, although compatible with 65W PD universal fast charging, but can not be considered a hundred watts of universal fast charging.
In February 2021, Xiaomi released the RedmiBook Pro 15 with a 100W USB PD charger (model: AD100) as standard, which is only a 20V5A 100W PD universal fast charging standard, a proper 100W PD universal fast charging charger.
In July 2022, Xiaomi launched the subsequent iteration of the AD100 charger — AD100G, upgraded to a gallium nitride solution with a smaller size, maintaining the 100W PD universal fast charging output for laptops and other universal PD fast charging based electronics.
The Xiaomi AD100G charger maintains the simple and understated design of the Xiaomi fast charger family, with no overly detailed outline and an all-white glossy housing and overall flat square shape.
Interface configuration, Xiaomi AD100G charger with a single output port configuration, macro camera shooting interface internal, specifications for non-full PIN USB-C interface.
There is a “100W” power mark printed on the side of the case, and the words “Designed by Xiaomi Communication Company” below.
Pins, the use of fixed pin design, the type of national standard two-pin.
The nameplate parameters section.
Name: Xiaomi GaN power adapter Type-C 100W
Model: AD100G
Input: 100-240V ~ 50/60Hz 1.6A
Output: 5V3A / 9V3A / 11V5A / 12V3A / 15V3A / 20V5A, 100W Max
Manufacturer: Nanjing Cooltech Electronic Technology Co.
Supervisor: Jiangsu Zimmy Electronic Technology Co.
Xiaomi AD100G charger dimensions are 31.75mm X 62.1mm X 61.93mm, volume 122.1cm³, according to the rated output power 100W, its power density is 0.82W/cm³, next to the comparison is the Apple 96W charger.
Look at the old AD100 charger in 2021, the three dimensions are 72.2×72.14×28.07mm, the volume is about 146.20cm³, the power density is about 0.68W/cm³, next to the same Apple 96W for comparison, it can be seen that the new version of AD100G changed to gallium nitride solution, the volume is smaller.
The three Xiaomi 100W+ chargers are compared side by side, from left to right, the Xiaomi AD100G GaN charger, the Xiaomi 120W USB-A Magic PD charger, and the Xiaomi 120W USB-C GaN charger. Only the leftmost one supports 100W PD universal fast charging output, while the right two only support 65W PD universal fast charging output.
Using the POWER-Z USB tester to read the Xiaomi AD100G PDO messages, we can see from the feedback results that the charger is developed based on the PD3.0 standard and supports five fixed voltage output grades of 5V3A / 9V3A / 12V3A / 15V3A / 20V5A, plus a subset of high-current PPS voltages from 5-11V5A, with a maximum output power of 100W.
In addition to the USB PD fast charging standard, a quick charging protocol poll reveals that the charger also supports the latest Qualcomm QC5 universal fast charging standard with QC3.0 fast charging protocol for broader compatibility with new and old devices.
The actual test on iPhone 13 Pro Max charging, inserted instantly that the correct handshake 9V PDO, power 8.97V 2.92A 26.25W, to reach the device fast charging power maximum.
The Redmi Note 11T Pro+ was charged with the correct handshake PPS high current fast charging at 9V 5.04A 45.45W, reaching the maximum charger 5A PPS output power.
Actual test on the iPad Air 5 charging, insert the instant that the correct handshake 15V PDO, power 15.04V 2.31A 34.83W, to reach the device fast charging power maximum.
The actual test charging MacBook Pro 16 2021, inserted instantly that the correct handshake 20V PDO, power 19.98V 4.64A 92.84W, to reach the device fast charging power maximum.
Finally, for the convenience of small partners to identify, I will Xiaomi four 100W + charger parameters made into a table, a chart to understand the difference.
Charging head network summary
Xiaomi AD100G charger relative to the old AD100, upgraded to gallium nitride solution, smaller size, the same performance to maintain 100W PD universal fast charging, with 5V3A / 9V3A / 12V3A / 15V3A / 20V5A five fixed voltage output gear, can provide high-power charging services for mainstream electronic products and even notebooks.
Another upgrade is the addition of 11V5A high-current PPS function. Most Android phones on the market today have private protocols based on PPS, and the AD100G’s support for 5A PPS gives it a more friendly fast charging compatibility.
AD100G has successfully taken over the baton of the 100W PD universal fast charging system and is moving forward together with the Xiaomi 120W system in the adjacent track, segmenting the market to serve different audiences. AD100G has arrived at the editorial office of charginghead.com, and a detailed disassembly review will follow, interested partners can pay attention to the follow-up update!
