Shop USB-C & Connectivity Adapters by Type

Adapters solve different connection problems. Some convert USB-C into an audio connection, others provide video output, while multiport products can add several connections from one device port.

USB-C to 3.5mm Audio Adapters

A USB-C to 3.5mm adapter lets a compatible USB-C device connect to wired headphones, earphones, speakers or AUX equipment that uses a traditional 3.5mm audio plug.

This can be particularly useful on modern phones and tablets that no longer include a dedicated headphone jack.

A USB-C audio adapter may be suitable for:

wired headphones
AUX cables
car audio systems
portable speakers
other compatible 3.5mm audio devices

Compatibility can vary between devices and adapters, so check the individual product listing before ordering.

If you are looking for the headphones themselves rather than an adapter, browse ourHeadphones & Earphones.

USB-C to HDMI & HDTV Adapters

A USB-C to HDMI adapter connects a compatible USB-C source device to an HDMI-equipped television, monitor or display.

This type of adapter can be useful for:

• connecting a laptop to a larger monitor

• displaying compatible phone or tablet content on a TV

• presentations

• extending or mirroring a compatible computer display

• connecting USB-C devices to existing HDMI equipment

One important point is that a USB-C connector does not automatically guarantee video output.

For many USB-C to HDMI connections to work, the phone, tablet or laptop must support compatible video output through its USB-C port.

If your device has USB-C but does not support the required video-output technology, an HDMI adapter alone cannot add that capability.

USB-C to DisplayPort Adapters

A USB-C to DisplayPort adapter can connect a compatible USB-C device to a DisplayPort monitor or display.

DisplayPort is commonly found on desktop monitors and professional display equipment.

As with HDMI, the source device must support compatible display output through its USB-C connection.

Always check:

your device's USB-C display support
the adapter's stated capabilities
the display connection
supported resolution where relevant

Do not assume every USB-C port provides exactly the same display functionality.

Lightning Audio & Video Adapters

Lightning adapters are useful for compatible Apple devices that use the Lightning connector.

Depending on the product, these adapters may provide connections such as:

Lightning to 3.5mm audio
Lightning audio and charging
Lightning to USB
Lightning OTG
Lightning video output

These accessories are particularly relevant to older iPhone generations and other compatible Apple devices that do not use USB-C.

If you are also comparing Apple phones, browse ourApple iPhones.

OTG & USB Connector Adapters

An OTG adapter lets a compatible phone or tablet connect directly to supported USB devices.

OTG stands for On-The-Go.

Depending on your device and adapter, this can make it possible to connect accessories such as USB storage, keyboards, mice, card readers or other supported USB peripherals.

OTG compatibility depends on the device as well as the adapter. A physical connection fitting into your phone does not automatically mean every USB accessory will work.

USB-C Multiport Hubs & Card Readers

A USB-C multiport adapter or hub expands one USB-C connection into several different ports.

Depending on the product, a multiport hub may include combinations of:

USB-A
USB-C
HDMI or other video output
Ethernet
SD card slots
TF or microSD card slots
USB-C charging input

This can be useful for laptops and tablets with a limited number of built-in ports.

A multiport adapter is especially practical for desk setups, travelling and connecting several accessories without carrying multiple separate adapters.

Choose an Adapter for What You Need

The easiest way to choose an adapter is to start with the connection problem you are trying to solve.

Connect Wired Headphones to USB-C

If your phone or tablet has USB-C but your headphones use a standard 3.5mm plug, look for a compatible USB-C headphone adapter.

Check whether the adapter is designed for audio output, calls or both if those features are important to you.

Do not rely on the USB-C connector alone because audio compatibility can vary between devices.

Connect a Laptop, Tablet or Phone to a TV or Monitor

For an HDMI television or monitor, a USB-C to HDMI adapter may provide the connection you need.

For DisplayPort monitors, choose a USB-C to DisplayPort option instead.

Before buying a video adapter, confirm that the source device supports video output through USB-C.

This is particularly important for smartphones and tablets, where USB-C ports can support different capabilities depending on the model.

Connect USB Devices to a Phone or Tablet

An OTG or compatible USB adapter can allow supported USB accessories to connect directly to a phone or tablet.

This can be useful when transferring files, connecting external storage or using supported USB peripherals.

Check both the phone's OTG support and the connector required by the USB device.

Charge and Listen at the Same Time

Some phones have one USB-C or Lightning port that is used for both charging and audio accessories.

A compatible audio-and-charge adapter can provide separate connections for wired audio and charging at the same time.

The exact charging power, audio compatibility and supported device models vary by adapter, so check the individual listing before buying.

Add More Ports with a Multiport Adapter

If your laptop or tablet has only one or two USB-C ports, a multiport hub can add several connections from a single port.

This may be useful when you need HDMI, USB devices, card readers or Ethernet at the same time.

However, the available functions still depend on the source device.

For example, connecting an HDMI hub to a USB-C port that does not support display output will not automatically create video capability.

Will a USB-C Video Adapter Work with Your Device?

Not every USB-C device supports external video.

This is one of the most important compatibility checks when buying USB-C to HDMI or DisplayPort accessories.

Check USB-C Video Output Support

USB-C describes the physical connector.

The port can support different features depending on the phone, tablet or computer.

For video output, many devices rely on compatible technologies such as DisplayPort over USB-C.

If the device does not support video output through its USB-C port, connecting a video adapter will not normally produce an image.

Always check the specification of your exact device model before ordering.

Check Resolution & Refresh-Rate Support

Video adapters can also differ in their supported display capabilities.

Some products may be listed for particular resolutions or refresh rates, while others have different limits.

The actual result depends on the complete connection, including:

source device
adapter
cable where applicable
monitor or TV
selected display mode

Do not assume every HDMI or DisplayPort adapter supports the same maximum resolution.

Check the Display Connection

Make sure the adapter output matches the connection on the display you want to use.

For example:

HDMI display → choose a compatible HDMI adapter.

DisplayPort monitor → choose a compatible DisplayPort adapter.

If additional converters are required, compatibility can become more complex, so checking both ends before ordering can prevent connection problems.

USB-C Adapter, Cable or Hub: What Is the Difference?

These terms are related, but they do not mean the same thing.

An adapter changes or adds a connection. For example, USB-C to 3.5mm or USB-C to HDMI.

A cable connects two compatible ports over a length of cable. For example, USB-C to USB-C.

A hub expands one connection into multiple ports, such as USB, HDMI, Ethernet and card-reader connections.

A charger supplies electrical power.

This distinction is useful when deciding what you actually need.

If you need a replacement charging or data cable rather than an adapter, browse ourUSB-C & Charging Cables.

If you need a mains, wireless or car charging unit, browse ourUSB-C & Fast Chargers.

Check Adapter Compatibility Before You Buy

Connector shape alone is not enough to guarantee compatibility.

Before ordering an audio, video or USB-C adapter, check your exact setup.

Start by identifying the port on your source device. Confirm whether it uses USB-C, Lightning, Micro-USB or another connection.

Then check the connection you are trying to add. This could be HDMI, DisplayPort, 3.5mm audio, USB-A, an SD card reader or several ports through a hub.

For video adapters, confirm that your phone, tablet or laptop supports external display output.

For audio adapters, check whether the product supports your device and required audio features.

For OTG accessories, verify that the source device supports OTG functionality.

For multiport hubs, check each feature separately. A hub may physically contain HDMI, Ethernet and USB ports, but the source device must still support the relevant function.

When charging through an adapter or hub, also check the stated charging capability rather than assuming every USB-C product passes through the same power.

Taking a few minutes to check these details can help prevent buying an adapter that physically connects but does not provide the function you expected.

Frequently Asked Questions About USB-C, Audio & Video Adapters

Does every USB-C port support HDMI or video output?

No. A USB-C connector does not automatically mean that a device supports external video. The phone, tablet or laptop must support compatible video output through its USB-C port for many HDMI or DisplayPort adapters to work.

Can I connect my phone to a TV with a USB-C to HDMI adapter?

Yes, if your phone supports compatible video output through USB-C and the adapter and television support the required connection. A USB-C port by itself does not guarantee HDMI output, so check your exact phone model first.

Will a USB-C to 3.5mm adapter work with any USB-C phone?

Not necessarily. USB-C audio support can vary between phones and adapters. Check the individual adapter listing and your device specifications before ordering, especially if you need microphone or call support as well as audio playback.

What is the difference between a USB-C adapter and a USB-C hub?

A USB-C adapter usually converts or adds a specific connection, such as HDMI or 3.5mm audio. A USB-C hub expands one USB-C port into several connections, which may include USB, HDMI, Ethernet and card readers.

What does an OTG adapter do?
