AI Verdict
This is a 1-to-3 gigabit Ethernet switch with USB-C power, not a passive splitter, designed to expand a single 1000Mbps port for up to three devices.
This device is a situational fit because it effectively addresses the common problem of insufficient wired Ethernet ports by acting as a small, powered gigabit switch. However, its 'splitter' branding can mislead users into incorrect expectations or network setups, especially if they try to use it like a passive splitter or directly with a modem.
If you need dedicated gigabit speeds for each connected device or more than three ports, look for a multi-port gigabit switch with a higher port count and potentially a dedicated power adapter.

Pros
- Expands one Ethernet port into three active 1000Mbps ports simultaneously.
- Maintains gigabit speeds up to 1000Mbps for connected devices, unlike passive splitters.
- Powered via a common USB-C cable, which is included.
- Plug-and-play functionality requires no configuration for immediate use.
- Compatible with a wide range of devices and cable types (Cat5/5e/6/7/8).
- Constructed from hard, impact-resistant PVC material for durability and heat dissipation.
Cons
- Requires external USB-C power to function, it's not a passive device.
- The term 'splitter' in the name can be misleading, as it functions as an active switch.
- The total 1000Mbps bandwidth is shared among all three connected devices.
- Incorrect network configuration (e.g., connecting directly to a modem) can lead to connectivity issues.
Dimension Scores
It provides 1000Mbps gigabit throughput, which is standard for modern wired connections, but the 1000Mbps is shared across three ports.
The PVC material and advanced socket technology are stated to ensure durability and stable, long-lasting connections, but without extensive user feedback, it's hard to rate higher.
It's plug-and-play with no configuration needed, making setup extremely simple.
As an unmanaged switch, it offers no specific security features beyond basic network traffic forwarding.
Best For
- Adding wired Ethernet ports to a single-port device like a smart TV or gaming console.
- Expanding a single wall Ethernet jack to connect multiple devices in a home office or entertainment setup.
- Users needing a compact, unmanaged gigabit switch for basic network expansion.
Not Recommended For
- Replacing a router or handling multiple public IP addresses from a modem.
- Environments requiring consistent high bandwidth across all devices simultaneously, like servers or data centers.
- Users expecting 1000Mbps speed *per device* when all three ports are actively transferring data.
Watch Out For
- Many users confuse this active switch with a passive Ethernet splitter, which would severely limit speeds to 100Mbps or less.
- Connecting this device directly to a modem and then to a router and another computer will likely cause network failure because modems typically only provide one IP address.
- The 1000Mbps speed is the total shared bandwidth, not 1000Mbps for each of the three ports concurrently.
- Requires constant USB-C power; it will not function without it.

What Buyers Say
This THXCDBID device, despite its 'splitter' label, functions as a compact 1-to-3 gigabit Ethernet switch, which is a crucial distinction for anyone trying to expand their wired network. It's designed to provide 1000Mbps speeds, but that's the total bandwidth shared by all connected devices. The main confusion users face is often around the difference between passive splitters (which are bad) and active switches (like this product). Some users might run into issues if they try to connect it directly to a modem, expecting it to handle multiple public IP addresses.
“Okay, so it's not really a 'splitter' like those old phone line things, it's a mini switch! Works fine for my PS5 and TV off one wall port, but yeah, gotta plug it in. Speeds are good enough, but don't expect full gigabit on all three at once if you're hammering it.”
Common Praise
- Provides a simple way to add more wired ports when only one is available.
- Maintains gigabit speeds for individual devices when not saturating the shared bandwidth.
- Easy to set up with its plug-and-play design.
- Compact size makes it easy to place discreetly.
- USB-C power is convenient and widely available.
Common Complaints
- Misleading 'splitter' name causes confusion about its functionality compared to passive splitters.
- Requires external power, which some users might not expect from a 'splitter'.
- The 1000Mbps bandwidth is shared, not dedicated per port, which can be a limitation for heavy users.
- Incorrectly connecting it to a modem can lead to network problems.
Ownership Tips
- The device runs cool even under load, thanks to its PVC material and design.
- The USB-C power cable is a standard length, which might require an extension in some setups.
- LED indicators for port activity are present, but their brightness might vary.
- The 'plug and play' aspect holds true, with devices connecting instantly without manual setup.
Frequently Asked Questions
Will this device slow down my internet speed?
No, this device is designed to maintain high-speed connections up to 1000Mbps. It functions as a gigabit switch, not a passive splitter, so it won't inherently reduce your speed.
Do I need to plug this into power?
Yes, this Ethernet switch requires external power via the included USB-C cable to function correctly and provide stable gigabit speeds.
Can I connect three devices and get 1000Mbps on each?
The device supports a maximum transmission speed of 1000Mbps, which is shared among the three connected devices. While one device can reach 1000Mbps, the total bandwidth for all three combined is 1000Mbps.
What's the difference between this and a regular Ethernet splitter?
This device is actually an active gigabit Ethernet switch, capable of managing and routing data at 1000Mbps to multiple devices simultaneously. A 'regular' passive Ethernet splitter typically only allows one device to connect at a time or severely limits speeds to 100Mbps.
Is it compatible with Starlink?
Yes, the THXCDBID Ethernet Splitter is compatible with Starlink, ADSL, hubs, switches, TVs, set-top boxes, routers, and wireless bridges.
Buying Guide
When you're trying to get more wired internet connections, you'll often see 'splitters' and 'switches.' A true Ethernet 'splitter' is usually a passive device that either lets you use only one connection at a time or severely limits your speed to 100Mbps. What you actually need for multiple devices to get fast, simultaneous internet is an Ethernet 'switch.' This product is an active switch, meaning it intelligently manages traffic and keeps your gigabit speeds. You'll need to power it, but it's worth it for the performance.

Alternatives
If you need more than three ports or dedicated gigabit bandwidth for each device without sharing, look for an unmanaged gigabit Ethernet switch with 5 or 8 ports. If you only need to extend a single cable run to a single device, an Ethernet coupler might be sufficient.
