Overview

The VEDINDUST Ethernet Splitter is a compact network accessory that expands a single LAN port into two. Its 1-in-2-out design gives you an extra wired connection for a second device without needing a full-sized switch. It supports Gigabit speeds (up to 1000 Mbps) when used with Cat6 or better cables, but note that the bandwidth is shared between the two connected devices — each gets a fraction of the total when both are active.
The unit comes with a 0.8m USB-A to USB-C power cable, but it requires a separate USB power adapter (not included) to function; bus power from a laptop USB port is not recommended. The housing is compact and black, making it unobtrusive on a desk or in a travel bag. Priced at around ¥9,818 (tax included), it sits in the entry-to-mid tier of home networking accessories.

Connectivity & Compatibility

This splitter uses standard RJ45 8P8C ports and is compatible with Cat5, Cat5e, Cat6, Cat7, and Cat8 Ethernet cables. It works with a wide range of devices: ADSL modems, hubs, switches, TVs, set-top boxes, routers, wireless access points, and computers. It is compliant with 1000BASE-T, so it can achieve up to 1000 Mbps in a gigabit environment when only one device is connected.
Power is delivered via USB-C using the included cable. The manufacturer recommends connecting the splitter to a dedicated USB power adapter rather than a laptop's USB port to ensure stable operation. The power cable is 0.8 m long, which is sufficient for desktop use.

Product Info

The product became available around 2024 and is primarily sold through Japanese online retailers. It comes with a 2-year warranty from the date of purchase, and post-sales support is available in Japanese. Included in the box are the splitter unit, a USB power cable, and a user manual (Japanese language support may be limited).
In terms of market positioning, this is an entry-to-mid level product. It lacks advanced features such as VLAN support, QoS, or management interfaces. Its strength lies in simplicity and low cost, making it suitable for home users or small offices that need a quick, low-hassle way to add one more wired connection.

Best Use Cases

  • Adding a second wired device in a home office or living room: If your router has only one free LAN port and you need to connect both a desktop PC and a game console, this splitter can handle the job. However, simultaneous high-bandwidth activities (e.g., large file transfers or 4K streaming on both devices) may cause noticeable slowdowns because the bandwidth is shared. For heavier use, consider a managed switch instead.
  • Temporary or travel networking: When visiting a co-working space or hotel room that provides only one Ethernet jack, this small splitter lets you connect your laptop and a VoIP phone or another device. Its compact size makes it easy to carry, but remember to bring a USB power adapter or a power bank for the splitter — it cannot be powered solely by a laptop USB port.
  • Budget-minded home users: At its price point, this splitter is an affordable way to gain an extra wired port without buying a full switch. It works well for basic internet browsing, email, and light streaming. If you need more than two ports or require advanced network features, a 5-port unmanaged gigabit switch (often at a similar price) would be a better investment.
