PicksHive Take

The SABRENT USB 2.0 to Serial 9-Pin DB-9 RS-232 Cable is for connecting a computer’s USB port to equipment with a traditional RS-232 serial connection. The listing names devices such as modems, PDAs, digital cameras and ISDN terminal adapters. At the current $13.99 price, it is worth considering when that specific connection is what you need—not simply because an older device needs a replacement cable.

Match both connector ends to your equipment first. The 9-pin DB-9 RS-232 connection is the key distinction here, and the listed male thumbscrews help secure it to your serial device. The six-foot length gives you extra reach between equipment, though it also means more cable to manage if everything sits close together. This is a specialized connectivity purchase, not a cable to choose by charging wattage or modern USB data-speed claims.

The listing specifies a genuine FTDI chipset and advertises plug-and-play, driverless installation on multiple operating systems. However, the supplied details do not name those systems, so check the listing for your exact OS before buying. Remote wake-up, power management and separate 96-byte upstream and downstream buffers are also listed. PicksHive has not tested this cable by hand.

Skip it if you need an ordinary USB connection rather than RS-232. The Cable Matters 5Gbps USB 3.0 Cable is a different option for a USB data connection, provided its ends match your devices; its 5Gbps rating does not make it a substitute for serial conversion. Likewise, the Amazon Basics USB 2.0 Cable should be considered only after checking its connectors. The main trade-off is specialized serial connectivity versus general-purpose USB use.

What to know before buying cables & adapters

PicksHive buying note

Match both connector ends to your devices before anything else. For charging, check the rated wattage (60W vs 240W); for data or displays, check the rated speed (USB 2.0 is 480Mbps, USB4/Thunderbolt reaches 40–80Gbps). Longer cables can charge fine but often run at lower data speeds, and Lightning cables labelled MFi are certified by Apple.
