USB-C, USB PD, and Power Delivery
The USB PD specification is also closely intertwined with USB Type-C. Currently, a USB 2.0 connection provides up to 2.5 watts of power—enough to charge your phone or tablet, but that’s about it. The USB PD specification supported by USB-C ups this power delivery to 100 watts. It’s bi-directional, so a device can either send or receive power. And this power can be transferred at the same time the device is transmitting data across the connection. This kind of power delivery could even let you charge a laptop, which usually requires up to about 60 watts.
Apple’s new MacBook and Google’s new Chromebook Pixel both use their USB-C ports as their charging ports. USB-C could spell the end of all those proprietary laptop charging cables, with everything charging via a standard USB connection. You could even charge your laptop from one of those portable battery packs you charge your smartphones and other portable devices from today. You could plug your laptop into an external display connected to a power cable, and that external display would charge your laptop as you used it as an external display — all via the one little USB Type-C connection.
There is one catch, though—at least at the moment. Just because a device or cable supports USB-C does necessarily mean it also supports USB PD. So, you’ll need to make sure that the devices and cables you buy support both USB-C and USB PD.
10. Can You Use a USB Keyboard on a Smart TV?
You can plug a USB keyboard into the USB port of your smart TV.
The USB port was designed to work with both wired USB keyboards and wireless keyboards.
5. Can Smart TVs Play PowerPoint Files from USB?
Smart TVs cannot play PowerPoint files from the USB port.
If you want to display a PowerPoint presentation on your smart TV’s screen, you can do the following:
- Upload your PowerPoint file to Google Drive, and open the file through your smart TV’s browser.
- Take advantage of screencasting or mirroring. You can use your smartphone or computer to cast the PowerPoint presentation through Chromecast, or AirPlay, if compatible.
- Save your PowerPoint file as a compatible video. This option will need you to time the slides and may not be practical.
Is The USB Port In A Wireless Router Used For Phone Tethering?
The USB port in a wireless router is not used for phone tethering. It is used for attaching storage and backup devices as well as charging low-power devices. However, with the right software and phone application that can set-up USB on your phone as a network port it’s technically possible to use it for phone tethering.
3. Firmware update
You can directly update your TV’s firmware to the latest version if connected to the internet. Another way to get it done is by downloading the latest firmware software of your TV model from the manufacturer’s support website on your computer. Transfer the file to a USB drive and connect to your TV.
Under the “Software Upgrade” section of your TV, choose the “update by/from USB” option. Your TV will automatically locate the update file and commence the update process.
Listening to Music via Car Audio USB
Every head unit is different, so you may have to fiddle with the options or even read the manual if you want to listen to music via the USB connection. In a perfect world, you would be able to simply plug in an MP3 player, or storage media with music files on it, the head unit would recognize it, and your music would play. However, that isn’t always the case.
If you’re using a phone or MP3 player plugged into the USB connection, then it’s often a simple matter of selecting the auxiliary or USB input. Some head units, in conjunction with specific phones, will also include additional functionality and may require you to open a corresponding app on the head unit.
Listening to music that’s stored on a USB thumbstick is often more complicated. You may get lucky and have everything work fine the first time you plug in the thumbstick, or it may take a little more work. For instance, you may find that your head unit can only read data from the thumbstick if it is formatted a certain way, such as FAT32 or NTFS. You may also have to dive into the head unit options to specify a location to find music on the thumbstick, or there may be a ‘sync’ option that will prompt the head unit to automatically locate music on any attached media.
Conclusion: What Is The Use Of USB Ports In Wireless Routers?
While USB ports seem like an odd feature in a Wi-Fi router, they are very important. This is especially true if you are looking to attach other network devices such as hard-drives, printers, and scanners that do not have wireless capabilities.
Besides connecting network devices, you can also use the USB ports on your router for charging low-power devices or powering cooling devices such as laptop coolers to prevent the router from overheating.
