Most new laptops and computers have at least one USB 3 port and they can often be identified easily as they’re blue in color. With much faster transfer speeds than USB 2.0, all of the USB 3 iterations are commonplace in all tech devices today. However, it is perfect for devices such as mice and keyboards. Many products today still harness this speed standard despite it being the slowest available. When USB 2.0 was introduced, it changed the connection game. By today’s standards, the transfer speed is outdated and there are very few devices using this now unless you have an ancient relic in your possession. This was the original standard when USBs first hit the market. There have been four generations of USB speed standard: USB 1.x However, it is worth bearing in mind that a connection type doesn’t dictate the data transfer speed. As connection types have evolved, so has the speed standard. Just like Apple have gone through generations of iPhones and iPads, USB connection types have shared a similar history.
This type of charging port is found on newer cell phones, GPS units, and some types of tablets, wearable tech and smaller digital cameras. Micro-USBĮven smaller still is the Micro-USB charging connection. As the name suggests they are much smaller than the other types of USB charging ports. Mini-USB sockets are typically found on digital cameras, external hard drives and some cell phones. Sometimes the port is featured on laptops but not for charging purposes. Also known as ‘Standard B’ connectors, they are not featured on any cell phones or tablets. Not so common, you will mostly find USB-B connections on external hard drives, printers, and other practical gadgets. USB-C ports are gradually becoming the norm and it is expected that the charging connection will eventually replace the traditional USB-A chargers completely. The port of USB-C is extremely narrow, allowing tech manufacturers to seamlessly integrate the port into new products. Many lightweight and slender devices required a charging facility that matched their stature, hence the birth of USB-C. Released in 2014, USB Type-C was a response to devices becoming slimmer.
Today, it is most commonly found on laptops, smart TVs, games consoles and media players. It is the original USB connector and is easily identified by its flat rectangular shape.
USB-A is likely the type of charger connection you are most accustomed to. Below, we highlight the most common charging connections you will see on your devices. However, finding a USB port on the go can still be difficult and the likelihood is you will need a power supply to attach the USB wire into a laptop or a computer with the relevant port. Most have created a USB connection on one end of the wire which can slot in and out of the receiving port of the plug.Ĭarrying around wires is a lot easier without the plugs attached. This development by major tech companies has made charging a little easier. You may have noticed that, particularly with newer devices, the plug and charging cable can actually disconnect. Furthermore, carrying bundles of chargers around for each of your devices can be cumbersome. However, finding a plug socket when you’re outside of your house or office can be like hunting for a needle in a haystack. They are convenient and typically included in the box when we purchase a new device.
Classic wall chargers are the method most of us are familiar with today.
