Through an USB expansion card, users can usually add five or more ports by fitting the board in a free PCI slot on the computer’s motherboard. The second variant unfortunately works just for desktop stations and it’s a more reliable option, as well as space-effective one. If you made up your mind, here’s a short list of our best options: They are usually pricier but also more stable.Īnother recommendation is to avoid chaining two or more USB hubs, pretty much from the same reason described above. To avoid this from happening you can opt for a powered USB hub, which comes with an AC charger. So, if you were to charge four smartphones directly from a hub, they would actually charge four times slower. When a splitter is used, this power is entirely transmitted to the external device and then split amongst all given slots. First of all, a single USB slot can deliver a certain amount of power. They go from $9 to $100 on Amazon, depending on form and builder.Īlthough an USB hub brings solid flexibility options, there are some downsides of the system.

In order to preserve space so that the end product becomes smaller and more portable, some manufacturers have come up with the brilliant idea of reducing the USB ports number to three or, in some cases, just two. Even though conventional desktop PCs come with a sufficient number of ports for a casual user, in most cases ranging from four to six, laptops or notebooks seem to have clear disadvantages. Usually, that USB limit is not so friendly. Whether we’re talking about smartphones, tablets, laptop lamps, cooling pads, computer mice, keyboards or any other device, it takes one USB plug to power or synchronize the monster. The bad part, as you already presume, is the fact that any host device, be it a conventional desktop computer, a laptop or a Mac, has a limited number of USB slots. Today almost any external gadget relies on a conventional USB port to perform a given task.
