Best Serial Cables of 2026

"I’ve been using this cable with my Quest 2 and it’s been recognized instantly, fits perfectly, and delivers smooth VR performance—I can move around my play space thanks to its generous length.

"After some trial and error, I found that using a 20W USB-C charger and the original Oculus cable fixed any charging warnings for me.

"The cable has been reliable for over a month of moderate use with my Quest 3—no connectivity or durability issues so far. I love how it lets me enjoy high-fidelity PC gaming for a fraction of the price of the official Meta Link Cable. For the cost, I’d definitely recommend giving it a try."

"I needed to hook up a Fluke 45 multimeter and a Tektronix TDS2024 oscilloscope to my computer, and this cable did the trick.

"I discovered this cable is actually an RS-232 DCE cable, which wasn’t exactly what I wanted, but it’s still really useful. To use it with devices like Cisco, I just add a male-to-male null modem adapter and it works as a DTE cable. The thin 10' cable is super convenient for carrying around, and it works with Windows 10 without issues. I like having a DCE cable handy for experimenting with serial ports."

"As a network engineer in a Cisco-heavy environment, I’ve tried multiple USB-to-RJ45 cables, but this one stands out for its sturdy clip guard and anti-snag design.

After installing the driver from the included CD on my ACER netbook, I was up and running without any trouble. The connection worked flawlessly with both the Arduino and my chosen terminal program. My only mild complaint is the lack of thumbscrews on the DB-9 end, but that's a minor issue considering the overall reliability and value."

So far, it has functioned exactly as expected, making it an easy recommendation for anyone in need of a dependable USB to Serial adapter."

"I’ve used this device for several years to connect to various equipment, and overall, it has proven to be a solid, long-lasting product. On rare occasions, I needed to update the drivers from the TRENDnet website, but those situations were quickly resolved. Consistent performance and hassle-free operation have made this a reliable part of my toolkit."

"I was impressed with how well this USB to COM adapter performed compared to older versions. For my vintage GCC Mercury I laser engraver, it transferred files quickly and reliably.
