USB C to USB C

A “Type‑C to Type‑C” cable means that both ends of the cable have the USB Type‑C connector (rather than USB‑A, or one end USB‑C and the other something else).

The USB Type‑C connector is a small, oval, reversible plug (you can insert it either way) with 24 pins. Wikipedia+3LaptopJudge+3yuxun.com+3

Because both ends are USB‑C, you can use the cable between two devices that each have USB‑C ports: for example, a laptop to a charger, a phone to a phone, a tablet to a charger, or for data transfer between USB‑C ports.

The cable is not just for charging: it may also support data transfer, video output (if the devices and cable support it), and power delivery. USB C Cable Manufacturer-Wand key

Importantly: with USB Type‑C cables, one must check the specification (power rating, data rate, etc.)—not all USB‑C cables are equally capable. SF Cable+1

???? Benefits

Here are the main advantages of using a good USB‑C to USB‑C cable:

Reversible connector & ease of use
You don’t have to worry about “which way is up” when plugging in the cable. The USB‑C plug works both ways. Laptop Judge
This makes it more convenient and reduces wear on the port from trying to plug incorrectly.

One cable can handle many functions
Unlike older cables (one for charging, another for data, another for video), a good USB‑C to USB‑C cable can:

Charge devices (from phone to laptop power)

Transfer data between devices

Carry video/audio signals (with “alternate mode” like DisplayPort or HDMI via USB‑C) yuxun.com+1
This simplifies your cable collection and setup.

Higher power delivery support
USB‑C with USB “Power Delivery (PD)” allows much higher wattage for charging. For example, cables might support 60 W (20 V/3 A), 100 W (20 V/5 A) or more depending on specs. USB C Cable Manufacturer-Wandkey+1
That means you could charge laptops, tablets, high‑power devices—not just phones.

Faster data transfer (if supported)
Depending on the USB/Cable spec, you may see data speeds of 5 Gbps (USB 3.0/3.1 Gen1), 10 Gbps (USB 3.1 Gen2), even 20–40 Gbps (USB 3.2/USB4) with the right cable & device. USB C Cable Manufacturer-Wandkey
This is useful when transferring large files, using external SSDs, monitors, etc.

Universal & future‑proof
With many modern devices adopting USB‑C (phones, tablets, laptops, monitors), one USB‑C to USB‑C cable can serve multiple devices rather than needing device‑specific cables. SF Cable
Also, because the connector is standard, compatibility is strong (though you still need to check specs).

???? Things to Describe / Look For (especially for a 1.5 m cable)

When you are picking a USB‑C to USB‑C cable (e.g., your target 1.5 m length), here are the descriptive/spec details you should pay attention to:

Length: You want ~1.5 m (which gives good reach without being too long).

Power/Wattage rating: Does the cable support e.g., 60 W, 100 W, etc? If you will charge a laptop or power‑hungry device, you want higher wattage support. USB C Cable Manufacturer-Wandkey+1

Data transfer speed: Is it only USB 2.0 (480 Mbps), or USB 3.1 (10 Gbps) or more? If you’ll use it for transferring large files, go with higher speed. USB C Cable Manufacturer-

Video/Alternate Mode support: If you want to connect to an external monitor, check if the cable supports DisplayPort Alt Mode or similar. yuxun.com

Build quality: Braided vs plain, reinforced connectors, good shielding—these affect durability. Also check for trusted certification (e.g., USB‑IF certified). 

Compatibility: Ensure the cable matches the device’s needs. Even if a cable is USB‑C to USB‑C, if it supports only basic specs, it might not fully charge a high‑powered laptop. Some cheap cables may not support all features. 

Why it matters (benefits in your everyday use)

Here are some real‑life benefits you’ll experience:

You can carry one cable and connect many devices (phone, tablet, laptop) since the connector is universal.

Your workspace is less cluttered: fewer types of cables, fewer adapters.

Faster charging: If you pick a 100 W‑capable cable and compatible charger/devices, you get quicker power‑up for your laptop or larger device.

Better future‑proofing: As you upgrade devices, the same cable can serve new USB‑C devices.

Transfer files quickly: If you have external SSDs or high‑resolution monitors, a high‑speed data cable will help.

Less frustration: Being able to plug the cable either way (no right/wrong orientation) is a small but nice convenience.

⚠️ Some cautions / limitations

Not all USB‑C to USB‑C cables support the highest specs—some are “charge only”, some only support USB 2.0 speeds, some don’t support video output. Reddit+1

Cable length can affect performance: longer cables sometimes reduce data speed or charging effectiveness. SF Cable

Device and charger must support the same protocols: e.g., if your laptop expects 100 W USB PD, but the cable is only rated for 60 W, you’ll get slower charging.

Using very cheap or non‑compliant cables can be risky (e.g., overheating, damage) per some sources. Wikipedia+1
