If you’re tired of carrying different cables for different devices, you’re not alone. I used to feel the same way—until I switched to USB-C.
USB-C is a universal cable standard that supports fast charging, high-speed data transfer, and works with a wide range of modern devices, all through a single reversible connector.
That sounds convenient, right? But there’s more you need to know before making the switch. Let’s dive deeper into the details behind USB-C and how it works.
How does USB-C differ from other USB types?
If you’ve ever struggled with plugging in an old USB cable the right way, I know the frustration. I’ve broken more ports than I care to admit.
USB-C is smaller, faster, and reversible. Unlike USB-A or Micro USB, you can plug it in any direction, and it supports both power and data through one cable.
Size and Shape Comparison
| USB Type | Reversible | Size | Common Usage |
| USB-A | No | Large | PCs, keyboards |
| USB-B | No | Medium | Printers, scanners |
| Micro USB | No | Small | Older phones, cameras |
| USB-C | Yes | Small | Phones, laptops, tablets |
Speed and Power
USB-C supports up to 240W of power and 40 Gbps data transfer via USB 4. Traditional USB-A maxes out around 12W and 480 Mbps for USB 2.0. That’s a massive leap.
What’s more, USB-C supports alternate modes like HDMI, DisplayPort, and Thunderbolt, which means a single cable can power displays, external drives, and even charge your laptop—all at once.
At Wandkey, we manufacture USB-C cables that support the latest standards—from USB 2.0 to USB4—helping customers meet performance needs across various devices and industries.
Can USB-C cables charge all devices?
I used to think any USB-C cable would charge anything. Then I tried charging my laptop with a cheap cable. It didn’t go well.
Not all USB-C cables are created equal. While the port looks the same, different cables support different power levels and data speeds.
Charging Capabilities of USB-C
| Cable Type | Max Power | Use Case |
| USB to USB-C Cable | 18W | Phones, earbuds, monitors |
| USB C to USB C Cable (Power Delivery) | 240W | Laptop, Tablet, Phones, Power Bank, etc |
Device Compatibility
The trick is matching the cable to your device’s needs. Some gadgets only need a few watts to charge, while others, like laptops or gaming consoles, may require 60W or more.
At Wandkey, we help businesses and brands choose the right specifications. Whether you’re looking to charge phones, laptops, or high-performance medical or industrial devices, we offer custom cable solutions to fit your product needs.
What data transfer speeds does USB-C support?
One time I transferred a 4K video using a cheap USB-C cable. It took forever. That’s when I learned not all cables are built for speed.
USB-C supports a wide range of data speeds, depending on the internal specs of the cable and device. It can range from 480 Mbps to 40 Gbps with Thunderbolt.
USB-C Data Speed Standards
| Protocol | Name | Speed |
| USB 2.0 | USB 2.0 | 480 Mbps |
| USB 3.2 Gen1 | USB 3.0 | 5Gbps |
| USB 3.1 Gen 1 | ||
| USB 3.2 Gen 1 | ||
| USB 3.2 Gen2 | USB 3.1 Gen 2 | 10Gbps |
| USB 3.2 Gen 2 | ||
| USB 3.2 Gen2x2 | USB 3.2 Gen2x2 | 20Gbps |
| USB4/Thunderbolt 3/4 | USB4/Thunderbolt 3/4 | 40Gbps |
Choosing the Right Speed
Many users mistakenly believe that all USB-C cables are fast. But the truth is, speed depends on the version. Always check specs.
At Wandkey, we produce USB 2.0 and USB4-compatible cables that support up to 40 Gbps for clients in video production, gaming, and other high-data-demand industries. Our team works with brands to tailor cable performance to their use case.
Is USB-C compatible with older USB ports?
When I first got a USB-C device, I was worried it wouldn’t work with all my old accessories. Thankfully, I found out there’s a way.
Yes, USB-C can be made compatible with older USB-A, Micro USB, or USB-B ports using adapters or hybrid cables. But speeds and power may be limited.
What You Lose
Using adapters or hybrid cables can help you keep using old hardware. But it comes with trade-offs:
Reduced speed and power delivery
No video or Thunderbolt support
Unstable data transfer in some cases
How to Choose a High-Quality USB-C Cable?
I’ve wasted money on cheap cables that stopped working after a week. Now I always check a few key things before buying.
A high-quality USB-C cable should support the latest USB standards, have certified safety chips, and match your power and speed needs.
What to Look For
| Feature | Why It Matters |
| Certified (e.g., USB-IF,UL/CE/FCC/RoHS) | Ensures safety and compatibility |
| Labeling | Shows speed and power rating |
| E-marker chip | Required for 60W+ cables |
| Brand reputation | Quality and longevity matter |
