Recently, ZENDURE has launched a new 65W gallium nitride charger - SuperPort S3 Pro. This charger continues the Roman column appearance design, equipped with foldable plugs and the popular 2C1A interface. At first glance, many people may think there is no difference, but after comparison, there are still significant differences.

Although the ZENDURE 65W gallium nitride charger SuperPort S3 is already very small, the Pro version is even smaller. As a multi-port charger, its power density even reaches 0.97W/cm³, making it very compact and portable. Secondly, it supports a dual-port charging strategy of 45W+20W, which can simultaneously meet the fast charging requirements of both MacBook and iPhone 12. Below, the Charging Head Network will conduct a detailed disassembly of this new product from ZENDURE to take a look at its specific design and materials.

Charging Head Network Disassembly summary

The new 65W gallium nitride charger SuperPort S3 Pro from ZENDURE continues the Roma Zhu ID design in appearance, but is smaller in size. In terms of performance, it closely follows the current popular 20W market and supports the dual fast charging requirements of iPhone 12 and laptops. In addition, the charger supports mainstream fast charging protocols such as QC, AFC, FCP, SCP, PE2.0, PD and PPS, with excellent overall compatibility. It can meet the fast charging needs of the vast majority of devices on the market. The dual C ports support blind power insertion, making it convenient to use.

Charging Head Network has learned through disassembly that as a columnar charger, it adopts a classic three-section layout design inside, with clear layers. Small boards are set at the input and output ends to make full use of the internal space. Secondly, the charger adopts a switching power supply plus two DC-DC architectures, which is also very typical.

The switching power supply is composed of a main control from ON Semiconductor, a NAVitas NV6115 gallium nitride power chip, and an MPS synchronous rectifier controller with a Weizhao rectifier tube. The solution is mature and reliable. Both secondary step-down circuits at the output end adopt Zhirong SW3516H and Ruijun RUH4040M2, and the overall materials used are mainstream.
