Get Full Charge From A USB Hub Port
You need to charge your Android smartphone, sync your iPod, backup your files with an external hard drive, and use a mouse – all at the same time – on your computer. With all of the devices that you need to attach to your laptop, it is likely that the standard amount of three USB ports that most laptops have won’t be enough to accommodate all of them. The solution to this is a USB hub, a device that allows you to expand the number of USB ports so that you can connect more devices to a host system.
However, issues sometimes arise when trying to use a USB hub for all of your devices. You may find that when you use a USB hub, your devices may work or charge at a suboptimal level, or may not even work or charge at all, and defeats the purpose of getting something that will make all the functions possible.
Why Does My USB Hub Recharge My Devices So Slowly?
Although standard USB hubs can accommodate more devices, it may not push through the amount of power needed by your gadgets. So if you are using a USB hub with four ports, then those four ports have to share the power that is usually reserved for one port. This works fine when plugging in the promotional USB drive you picked up at a company event, but devices that draw a lot of power will go slowly. Tech gadgets with small power would be fine, but those which require more power, such as external hard drives and smart phones, will most likely experience interference in the functionality.
Boost Your Power–Plug It In!
USB hubs are either bus-powered or self-powered. A bus-powered USB hub draws its power from the system that it is connected to; as a mobile device, this is acceptable for devices with low power requirements. However, for devices in need of more power, a self-powered USB hub is an excellent way to expand the number of ports for your system without having to compromise power requirements. Although it requires an external power supply which makes it less mobile than a bus-powered USB hub, it can provide full power to each of your devices. Self-powered USB hubs also have a wide range of available ports. There are some available in the market that can even provide power for up to 127 devices at the same time!
So if you need to expand the number of USB ports for your system while ensuring that each of your devices has an adequate amount on power, a self-powered USB hub is most likely the most worthwhile investment.
