Question about Thunderbolt 4 USB-C issues
Hi,
Thunderbolt 4 on a laptop often refers to a USB-C port, so you could charge your Samsung Galaxy phone using a USB-C cable connected to the Thunderbolt 4 port.
Can a laptop with a Thunderbolt 4 port be powered by your Samsung charger? This would mean you can use your phone charger directly without needing the laptop's power adapter.
Does a Thunderbolt 4 port allow outputting 4K at 120Hz to an HDMI 2.1 TV? If so, will the laptop have enough power for this use case aside from gaming?
The laptop's specifications and manual detail its performance capabilities, dimensions, and features.
Haven has purchased the laptop already, I'm curious about those Asus OLED models with Thunderbolt 4 ports. Just want to confirm before you buy, since I don't like carrying power bricks and if it can be charged via a USB cable would be ideal.
Yes, if the laptop features a Thunderbolt 4 port it is capable of charging your USB-C smartphone.
Various factors influence the charging rate, such as whether the laptop is connected or powered on.
Charging your phone while the laptop runs on battery may deplete the laptop's power.
Be careful not to mix USB-C and Thunderbolt 4.
USB-C is the physical connector shape, whereas Thunderbolt 4 is a technology standard created by Intel that utilizes the USB-C connection.
Thunderbolt 4 can transmit power, data, video, and networking through one connection.
USB3 and USB4 also support USB-C connections, depending on the charger's output.
The required wattage matters; for example, a 45W Samsung charger might need up to 65W from a laptop.
A 20W charger won't work with a Samsung 45W charger, nor will it charge a low-power Chromebook.
My XPS 15 uses a 130W USB-C charger, so most phone chargers won’t supply sufficient power for such a device.
If your TV supports 120Hz over HDMI, you may need to share the laptop and TV models for precise information—otherwise it could be uncertain.
Some Asus OLED laptops include Thunderbolt4, while others only use USB3, both sharing the same USB-C connection.
