ROG Player Country is an ASUS high-end series, including motherboards, graphics cards, notebooks and other product lines, creating more extreme products for players. In the middle of August last year, the charging head network had a revelation, ASUS European accessories mall on the shelves of a ROG 100W PD fast charger, the fuselage design of the "eye of the loser" is still so conspicuous.
Recently, the charging head network finally got the National Bank version of this charger, although the exaggerated "Eye of the Loser" logo was changed to the "point" element of the ASUS phantom series laptop, but from the overall style and parameter comparison, it was found that the two versions of the charger are essentially the same.
This charger adopts a split cable design, the power cord can be removed and replaced, and it comes with a USB-C output cable, although the style is traditional, but the body size is relatively small, and it supports 100W PD fast charging, which meets the needs of many styles of laptop charging under ASUS. The following charging head network will disassemble this charger in detail to see how the internal materials of the product work.
The charging head network has also previously disassembled the ASUS QC5 certified 65W PD fast charge charger, the ASUS game book 300W charger, the ASUS 48W 3A1C fast charging travel charger, the Asus 45W PD fast charger, the ASUS 65W Gallium nitride charger and other products, welcome to check it out.

Charging head net disassembly summary
Asus's ROG 100W PD fast charger is designed for the magic series of laptops, and unlike the common notebook power adapter, it adopts a boxy shape design, and the overall size is much smaller. In addition, it supports PD3.0 universal fast charging protocol, with four voltage gears of 5V3A, 9V3A, 15V3A, and 20V5A, which is suitable for asus notebooks and other mainstream digital devices.
Through disassembly, the charger adopts PFC+ QR switching power supply architecture design, specifically using ON Semiconductor NCP1611 with Infineon MOS tube for PFC boost, liquette, MPS primary secondary controller with Italian high voltage MOS and AOS synchronous rectifier tube to form a switching power supply, and the protocol chip is also from Lico.
In addition, the use of Kingsoft electrolytic capacitors and Wanyu ULR series solid capacitors for input and output filtering, a large number of adhesive gluing modules and the installation of heat sinks to help dissipate heat, to ensure long-term high power stable output. However, as far as the price of the European version of the charger was previously exposed, the price of the National Bank version is estimated to be not cheap, and on the whole, whether it is the workmanship material of the charger itself, or the price is very ROG.
