If you’ve made it this far while searching for a cable, then you definitely need one, and you’re probably unsure which cable will work best for you. So don’t worry! After reading this article, you will clearly know which cable you should buy.

There are many types of cables used in the industry, including network cables, electrical cables, Ethernet cables, and others. Now it’s up to you to choose which one you actually need.

In this guide, you will learn about all types of cables, their common uses, and which one is right for your purpose.

Cable Types: Which One Are You Looking For?

Before buying a cable, you need to understand why you actually need it. As I mentioned earlier, there are many different types of cables available.

Here are some common cable types that we use most of the time.

1. HDMI Cables

HDMI cables are necessary if you want a cable to move audio or video from one device to another. HDMI cables allow you to connect your laptop or PC to a monitor, game consoles, streaming devices, projectors, and presentations. You should definitely choose HDMI cables if your goal is to have both sound and a display.  

2. USB Cables

I don’t think there’s anyone nowadays who doesn’t know about USB cables. The same wires we use to charge our mobiles, to transfer data from a laptop to a phone, to connect any device, like connecting a mobile to a computer, and even connecting speakers.

We use USB cables for all these purposes. And if you also need one for any of these uses, then you should definitely choose a USB cable.

3. Ethernet (LAN) Cables

Nowadays internet and Wi-Fi are everywhere, and the cables used to connect the internet across the world are Ethernet cables. By using an Ethernet cable, you can connect the internet directly to your computer without needing a Wi-Fi source like a modem.

These cables are also used to connect Wi-Fi routers to the main internet source and to connect the internet directly to your computers or devices for faster data transfer. Mostly in offices and workspaces, you will notice that every computer is directly connected to the network using Ethernet cables.

The common types of Ethernet cables are Cat5e, Cat6, Cat7, and Cat8. But the most commonly used one is Cat6, which is considered the best and more than enough for most people.

4. Power / Electrical Cables

All the wires we use in our homes for lights, fans, setting up other electrical wiring, and connecting UPS or power backup systems are called electrical or power cables. Almost everyone knows about electrical cables because these are the cables that keep our lights and fans running. These are a basic need in every home, and you will find them in every household.

5. Audio Cables (AUX, RCA, Optical)

All of the wires that connect speakers, headphones, sound systems, and car audio are audio cables; if you want to play music or sounds, you will need audio cables.

Factors to Consider Before Buying Any Cable

Here are some things you should always think about before purchasing any cable to help you make the best decision. 

• Cable Type: Consider your purpose, then choose the type of cable you require, and then buy.
• Connector Compatibility: If you are looking for a cable to connect devices, always check the size of your computer’s port so that the cable fits perfectly. 
• Length: The length of the cables is also important if you’re looking for Ethernet cables. Don’t buy it too long or too short. Because if you buy it for longer than needed, your network speed and signals will be impacted.
• Build Quality: Build quality is also important for long-term use. Always buy braided and reinforced cables.
• Speed and Performance: If you want faster and better performance, then always go for the USB version, HDMI standard, or Ethernet category. 
• Durability: Before choosing a cable, always look for materials that are strong enough to endure regular bending and daily use.
• Price vs Value: Expensive cables aren’t always better; check if the features match your needs.
• Certifications: Always look for certifications like HDMI certified or USB-IF for safety and performance.

How to Identify Good vs Bad Quality Cables

Quick Recommendations (Beginner Budget + Premium Options)

For beginners, we’ve listed the best cable recommendations for each cable type, from budget-friendly options to high-quality, durable cables. 

Best all-purpose HDMI Cable for Beginners

Best Power Cables for Common Use

The most commonly used power cables in our houses are 18 AWG (or thicker), which are considered standard and always the best option. These cables are thick enough to safely power fans, lights, and small appliances without overheating.

But if you’re connecting a UPS or power backup system, choose a power cord with enough insulation and voltage rating (usually 10-15 amps / 125 volts or as needed).

For more demanding devices, such as high-powered desktop PCs or large appliances, you should choose a thicker gauge cable (16 AWG or 14 AWG) to ensure stability and safety.

Before choosing a power cable, carefully consider your needs and then choose based on voltage compatibility, plug type, and device wattage. 

Best Audio Cable for Simple Setups

Audio cables are available in three types: AUX (3.5mm), RCA, and Optical (Toslink). But if you only need to connect speakers, headphones, or home entertainment systems, a 3.5mm AUX or optical connection would be enough. 

You should choose this one because it is less expensive and more readily available, making it easier to get. Also, you will not have to deal with any technical issues when using them.  

Other Audio Cable Types:

• AUX (3.5mm): For headphones, speakers, and car audio.
• RCA: Used for TVs and sound systems (red, white, yellow plugs).
• Optical (Toslink): Delivers high-quality audio with no interference.

Tips to Make Your Cables Last Longer

It makes no difference what type of cable you need, but to keep them working for as long as possible, you need to provide proper maintenance. We have listed some tricks you can apply to help your cables last longer.  

1. Proper Storage

How you store your wires is actually important. If you don’t use them much, keep them properly in loops rather than tight knots. If you tie tight knots, the internal wires may break. So keeping your cables in good condition is essential. To prevent internal wire breakage and tangling, you can use cable organizers and Velcro straps.

2. Avoid Over-Bending

Sometimes, what happens is that after using our USB cables, Ethernet cables, or any power cable, we just leave them as they are or bend them while storing them. This causes the internal wires to break due to bending, and even the outer rubber coating that protects the internal wires can get damaged.

So, to keep your cables safe, avoid bending them.

3. Clean Connector Regularly

Always keep your connector clean, because dust and dirt could cause problems with the performance of your cables if they are not properly cleaned. 

4. Invest in Durable Cables

The biggest mistake that beginners make is to buy low-quality plastic cables because of a limited budget. So you should always invest in high-quality braided or reinforced cables that will last longer and withstand more wear and tear than cheap plastic wires. 

Wrap Up

By now, you have a clear idea about all the common types of cables, their uses, and which one is best for your purpose. Whether it’s HDMI for video, USB for charging and data, Ethernet for internet, power cables for home, or audio cables for music, choosing the right cable will make your setup smooth and hassle-free.

Always consider quality, durability, and compatibility before buying any cable. With the tips shared in this guide, even beginners can confidently pick, maintain, and use cables that last longer and give the best performance for their needs.
