Additionally, the multi usb charger features foldable pins, which further enhances its portability and prevents the metal prongs from scratching other items in your travel bag.

4. Broad Protocol Compatibility for the Multi USB Charger

A modern multi usb charger is only as good as the devices it can support. Extensive testing reveals that this multi usb charger is compatible with a vast array of fast-charging protocols, including PD3.0, PPS, QC3.0/4+, FCP, SCP, and AFC. Such wide-ranging support ensures that the multi usb charger can provide optimal charging speeds for various brands like Apple, Samsung, and Huawei. The PDO (Power Delivery Objects) of the multi usb charger include fixed voltages such as 5V/3A, 9V/3A, 15V/3A, and 20V/2.25A, ensuring that this multi usb charger is truly a universal power hub for your digital ecosystem.

5. Internal Mechanical Precision of the Multi USB Charger

The internal teardown of the multi usb charger reveals the engineering prowess required to combine electronics with moving parts. The retractable module within the multi usb charger utilizes a sophisticated axis with three brushes. This design is crucial for a multi usb charger because it ensures a stable electrical connection even as the cable is being pulled or retracted. By increasing the current-carrying capacity through these brushes, the multi usb charger maintains efficiency and safety. This attention to mechanical detail distinguishes a high-quality multi usb charger from cheaper, less reliable alternatives on the market.

6. GaN Power Efficiency in the Multi USB Charger

At the heart of this multi usb charger lies the Gallium Nitride (GaN) power chip. Specifically, the multi usb charger employs the Hynetek HYC3657, which integrates a 650V GaN power device. GaN technology allows the multi usb charger to operate at much higher frequencies than traditional silicon chargers, which in turn leads to higher efficiency and less heat generation. This is why such a small multi usb charger can output 45W without overheating. The integration of GaN also allows the multi usb charger to have a smaller internal transformer, contributing to the overall lightweight and compact nature of the device.

7. Advanced Power Management and Secondary Buck Circuitry

To manage the dual-port output efficiently, the multi usb charger utilizes two Ismartware SW3526S chips. These chips act as secondary buck converters and protocol controllers within the multi usb charger. Each chip is responsible for one output path, allowing the multi usb charger to intelligently negotiate power delivery with the connected device. This dual-chip architecture is what enables the multi usb charger to switch seamlessly between single-port 45W and dual-port 20W+20W modes. The reliability of these chips ensures that the multi usb charger provides a safe and consistent charging experience every time.

8. Thermal Management and Safety Features

Safety is a top priority for any high-power multi usb charger. During the disassembly, we observed that the multi usb charger is filled with thermal conductive adhesive. Furthermore, the inner walls of the multi usb charger shell are lined with thermal pads and aluminum foil. These elements work together to dissipate heat away from the internal components of the multi usb charger. By maintaining a lower operating temperature, the multi usb charger ensures the longevity of its internal capacitors and semiconductors. This robust thermal design makes the multi usb charger a safe choice for prolonged charging sessions.

9. Premium Component Selection in the Multi USB Charger

Beyond the main chips, the multi usb charger is built with premium components from reputable manufacturers. For instance, the rectifier bridge comes from Yangjie Electronic, and the high-voltage filtering capacitors are supplied by ChuangHui. The multi usb charger also features specialized SMD Y-capacitors from TRX, which are designed to save space while providing excellent EMI protection. Even the MCU (Microcontroller Unit) used for power distribution in the multi usb charger is a high-quality 8-bit RISC chip. Such meticulous component selection ensures that the multi usb charger meets strict certification standards like CCC and Level VI energy efficiency.

10. Conclusion and Future of the Multi USB Charger

In conclusion, the TORRAS 45W retractable GaN multi usb charger is a testament to how innovation can improve daily life. It is more than just a multi usb charger; it is a solution to the common problem of cable management. By combining GaN efficiency with a clever mechanical design, this multi usb charger offers performance, convenience, and style. As users continue to demand more streamlined tech, the multi usb charger will likely become the standard for mobile power.
