USB 2.0 supports 2.5W charging and USB 3.0 supports 4.5W charging. To put things in perspective, 10W is enough power to slow charge your phone, and 18W is enough to fast charge your smartphone or power a Netbook or similar bare-bones laptops.
This guide will provide you with a detailed overview of USB connector types, exploring compatibility options and covering connection variants to enhance your digital experiences. So, lets delve into the intricacies of USB cables and adapters and learn why they continue to shape the landscape of modern connectivity.
Most computers and electronic devices have some form of USB connection, and many devices also come packaged with a USB cable. What are all these different cables for, and why does it matter which one you use?
It can be somewhat complicated to wrap your head around all this. Here''s everything you need to know about the USB standard, including how to identify various USB cable types and what they do.
USB is supposedly universal, but there are so many different types of USB cables and connections. Why is this? As it turns out, they each serve different functions, mainly to preserve compatibility and support new devices.
In most cases, you''ll find USB cables have one standard type-A end and one type-B end of some sort. The type-A end powers the device, while the type-B end receives power. This is to prevent potential damage that would be caused by connecting two computers via USB-A, for example.
USB connection types are only half the story, as USB has also gone through multiple standards of varying data transfer speeds. The cable''s connector doesn''t necessarily mean that it uses a certain standard.
You can use a USB 2.0 device in a USB 3 port, or a USB 3 device in a USB 2.0 port, but neither setup provides the extra speed benefit. USB 3 has also gone through several "generations" that are confusing to keep track of. Read through our comparison of USB-C and USB 3 for more information on this.
The below chart shows what connector types are compatible with which standards. Notice that micro-USB devices which support USB 3.x have a different plug. You''ll often see this on external hard drives.
USB-C is the latest cable standard, and has lots of benefits. It''s smaller than USB-A, reversible, and fast. USB-C can both receive and provide a lot more power than previous versions of USB. In fact, Apple''s MacBooks now only have USB-C ports.
Unlike USB-A, cables with USB-C connectors on both ends are standard and allow full utilization of its powers. However, USB-C to USB-A cables are also common, allowing for compatibility with older devices.
If it''s newer, your Android phone or tablet likely uses USB-C instead of micro-USB. Some laptops and tablets feature a USB-C port; the Nintendo Switch uses it for power too. Since USB-C hasn''t been adopted everywhere yet, you might need to buy some USB-C to USB-A adapters to ease the transition.
Let''s say you have an external drive, a smartphone, and a laptop. What do you do if you want to move files from the external drive to the smartphone? The normal, yet tedious, way is to move files from the external drive to the laptop, then from the laptop to the smartphone.
With USB OTG, the smartphone can actually host the external drive, thus bypassing the need for the laptop altogether. And that''s just one of the many ways to use USB OTG.
To use USB OTG, you''ll need a suitable adapter (like the one mentioned above) so you can plug a USB-A cable into your phone. However, not all devices support OTG. If you''re not sure, check your phone''s manual or download an app like USB OTG Checker.
