USB Type-C cables are becoming increasingly popular, and for good reason. They’re lightning fast, durable, and easy to use. But be careful not to damage your devices when you buy one. Here are four tips to help avoid this:
- Make sure the cable is of the correct size. When buying a USB Type-C cable, make sure it’s the right size. A small USB Type-C cable can easily fit into a small port on a device, while a large USB Type-C cable can fit into a large port on a device. This will help reduce chances of damaging your devices if you use it.
- Use quality materials when making the cable. When making your USB Type-C cable, use quality materials such as metal and plastic. These materials will help keep your devices safe and sound when using it.
- Use a connector that’s compatible with your device. If you have an incompatible connector for your device, don’t buy the USB Type-C cable! Instead, try using another type of connector that is compatible with your device (like an HDMI or DisplayPort connector). This will help reduce chances of damaging your devices while using it.
USB Type-C brings a new universal connector to laptops and smartphones, and many devices are already starting to use it. But beware: many USB-C cables aren’t designed properly and could potentially damage your hardware.
Before buying any USB Type-C cables for your new devices, you should look up whether the cable is actually compliant with the USB-C specification. More people are sure to run into this problem as more USB Type-C-enabled devices are released.
Why a Bad USB-C Cable Could Damage Your Hardware
To be clear, the problem is specifically with cables that feature a USB Type C connector on one end and an older USB connector on the other end. For example, most devices still use USB Type A–the port you think of when you think “USB”. So if you get a USB Type-C device, you may want a USB-C-to-A cable to charge it on your older laptop or older power blocks.
Here’s the problem: USB Type-C devices can support faster charging, which is great. But most USB Type-A devices were never designed to provide as much power as a USB Type-C device can take.

For example, let’s say you have a computer with an older USB (Type-A) port and a new smartphone with a USB Type-C port. You’d connect the computer to the smartphone with a USB-Type-A-to-Type-C cable. A properly designed cable is supposed to prevent the smartphone from drawing too much power from the computer’s older USB port. A bad cable that isn’t designed properly will allow the smartphone to attempt to draw a larger amount of power, though, which could damage your computer or its USB port. It could damage a charger brick or USB hub, too–this isn’t just a problem when charging from a computer.
Even Smartphone Manufacturers Have Shipped Bad Cables
This isn’t just a theoretical problem. The only reason we haven’t heard much about it yet is because so few USB Type-C devices are out there in the wild, but this will change. Many cables–particularly less expensive ones–are not designed properly and will have this problem.
But it’s not just less expensive cables. Even the charging cable Oppo shipped with its OnePlus smartphone is a bad one. It doesn’t cause a problem when charging Oppo’s own OnePlus phone. However, plug that cable into another phone like Google’s Nexus 5X or 6P, and it could damage your devices. For whatever reason, manufacturers who design and manufacture these cables often don’t follow the specification properly.
How to Find a Cable That Won’t Damage Your Devices
Before purchasing a cable with a USB Type-C connector on one end and an older USB connector on the other, you should ensure it’s compliant with the USB-C specification and won’t damage your devices.
Hopefully, this is just a teething problem, and these noncompliant cables will vanish from the market as more people get USB Type-C devices. They also won’t be a problem once all the older devices with USB Type-A ports are gone, but that will take a long time.
The problems here demonstrate why Apple’s system of only allowing certified third-party Lightning cables to function isn’t such a crazy idea. A more open hardware ecosystem is great, but manufacturers need to do a better job of designing safe cables.
