HP 4.5mm and USB Dock Adapter (HSA-B006)

Introduction

Whether it’s a desktop or a laptop, for most ordinary users, these devices are typically used for 5-6 years or even longer, except for productivity-focused professionals and hardcore gamers who may frequently upgrade their equipment. However, the rapid popularity of USB-C ports in recent years has made it somewhat awkward to use these old devices.

To address this, HP has introduced a 4.5mm and USB Dock Adapter. This product features a USB-A port and an 4.5mm port on one end, and a USB-C port on the other end. This configuration allows it to support both charging via USB-C to old DC ports and data transmission from USB-A to USB-C, revitalizing old devices. Now let’s take a look at the internal components of this product.

Product Appearance

This adapter is compact and flat, with a short USB and 4.5mm DC extension cable. When paired with mainstream GaN chargers, it can easily be taken along and used to charge and transfer data for older laptops.

Its case is matte to resist fingerprints and has the HP logo on the top.

And all the specs info are printed on the back. Model is HSA-B006, it can support input of 20V3A, and the output can be up to 20V2.5A. It has passed CE, FCC, CP, VCCI, EAC, RCM, UL, KC certification.

The USB-C port with 24 pins is located at the bottom, as advertised by the official promotion, it can be used to connect to a docking station to achieve functions such as network sharing and display expansion.

On the other end, one of the extension cables terminates in a USB-A port, featuring an independent 9-pin design. It is officially stated to support the USB 3.0 transmission.

The other extension cable terminates in an HP-style old-fashioned 4.5mm port, which is now rarely seen on modern devices and is primarily used as a power supply port.

The extension cable lengths are approximately 16cm (6.30 inches) and 9cm (3.54 inches) respectively.
