4-in-1 multi-functional docking station

描述

The port configuration of the 4-in-1 docking station is: 2 USB ports + 1 Type-C port + 1 HDMI port. Although this combination seems simple, the choice of each port directly affects customer experience and after-sales service rate.

HDMI video output. The mainstream solution supports 4K@30Hz output and is backward compatible with 1080P@60Hz. For office presentations and daily movie watching scenarios, 4K@30Hz is sufficient, but it is necessary to clearly label “30Hz” on the product page instead of simply writing “4K” to avoid complaints from professional customers.

USB data port. It is typically configured as USB 3.0 standard, with a theoretical speed of 5Gbps and an actual measured speed of around 450MB/s. At least one of the two USB ports should be of 3.0 specification to ensure the transmission efficiency of devices such as external hard drives, while the other can be of 2.0 specification to control costs, but this needs to be clearly distinguished in the specification sheet.

The multifaceted role of the Type-C port. This is the most pivotal decision point in the design of a 4-in-1 product. The Type-C port can be designed for either power delivery (PD) only or both power delivery and data transmission. The version supporting PD 100W direct charging is more suitable for notebook users; if it also supports USB 3.0 data transmission, the product has greater potential for premium pricing, but attention must be paid to power distribution and heat dissipation issues when PD charging and data transmission are used simultaneously.

Portability and durability. The mainstream casing materials are aluminum alloy or ABS+aluminum alloy, with a weight controlled between 50g and 80g. The cable length is usually 15cm to 18cm, making it suitable for carrying around. The heat dissipation performance of aluminum alloy casing is better than pure ABS, with a significant difference when PD charging and HDMI output are running simultaneously
