It is obvious to all that the mobile phone industry is becoming more and more popular. In addition to the need for processors and other components to be fully stocked, charging, which was once not very important, has now become a battleground for mobile phone manufacturers. The recently released iQOO 9 series of mobile phones are all equipped with 120W ultra-fast flash charging as standard. Among them, the extra large model iQOO 9 Pro also comes standard with iQOO's new generation 120W gallium nitride flash charging kit.
Charging Head Network learned that iQOO 120W gallium nitride flash charger has two built-in NV6136A gallium nitride power chips from Nanosemiconductor. With the support of these chips, the volume is reduced by 26% and the weight is reduced by 35g compared with the previous generation. Actual measurement The power density is as high as 1.31W/cm³ and it is very lightweight.
iQOO 120W gallium nitride flash charging kit will be put on sale separately on January 15, priced at 299 yuan. This charging set currently supports 120W flash charging service for iQOO 8, iQOO 9, and iQOO 9 Pro. More models are being adapted and will be pushed through OTA later. During the event, old iQOO users can log in to the official website APP and snap up a limited number of this charging set for only 99 yuan, with a total quantity of 20,000 pieces.
Speaking of this, many iQOO users must be eager to try it. The time has come again to compete with hand speed. Below, Charging Head Network will take the first step to dismantle this charger in detail and show you the materials and workmanship of the charger.
