Useful USB gadgets solve specific PC problems: too few ports, mismatched connectors, account sign-in needs, or a missing wired-network connection. Here are five practical categories, with the compatibility checks that matter before you buy. They are not a ranked or tested “best of” list; the right choice depends on your PC and how you use it.
Check your PC before choosing a USB gadget
USB-C describes the connector shape, not everything a port can do. Depending on the computer, a USB-C port may support data, charging, video output, or only some of those functions. Check your PC’s manual or specifications before buying a hub or display accessory; Dell’s USB ports FAQ explains why capabilities vary by device.

Also distinguish connector type from data speed. USB 3.2 includes 5, 10, and 20 Gbps speed tiers, and a connection operates at the lowest speed capability shared by the devices and cable in the chain. See the USB Implementers Forum’s USB 3.2 overview. A faster-rated gadget cannot make a slower host port or cable faster.

A hub is useful when a laptop or compact PC has too few connections for peripherals, external displays, or wired networking. Depending on its design, a hub may combine USB data ports with HDMI, Ethernet, and power pass-through. Those features—and their limits—vary by hub and host PC.

What to check
- Port mix and data rates: Make sure the hub has the connectors you need and check each port’s supported speed.
- Display support: Confirm the PC’s USB-C port can output video, then compare the hub’s maximum resolution and refresh rate with your display.
- Power: Check whether the hub supports power pass-through and whether its power arrangement suits your PC and attached devices.
- Host limitations: A hub’s advertised display capability does not guarantee that every computer will produce that signal.
For one model-specific example, Anker lists its 533 USB-C Hub with three USB data ports, HDMI up to 4K at 30 Hz, and 1 Gbps Ethernet. Those are the manufacturer’s listed specifications for that model, not universal hub features or a guarantee about the output of a particular PC.
2. Dual USB-A/USB-C flash drive: move files between connector types
A dual-connector flash drive can make file transfers simpler when you move files between computers or other devices that have different USB connectors. Before buying, check that both ends fit the devices you intend to use and that the drive’s capacity, interface, and operating-system support meet your needs.
Rank #2
- 5-in-1 Connectivity: Equipped with a 4K HDMI port, a 5 Gbps USB-C data port, two 5 Gbps USB-A ports, and a USB C 100W PD-IN port. Note: The USB C 100W PD-IN port supports only charging and does not support data transfer devices such as headphones or speakers.
- Powerful Pass-Through Charging: Supports up to 85W pass-through charging so you can power up your laptop while you use the hub. Note: Pass-through charging requires a charger (not included). Note: To achieve full power for iPad, we recommend using a 45W wall charger.
- Transfer Files in Seconds: Move files to and from your laptop at speeds of up to 5 Gbps via the USB-C and USB-A data ports. Note: The USB C 5Gbps Data port does not support video output.
- HD Display: Connect to the HDMI port to stream or mirror content to an external monitor in resolutions of up to 4K@30Hz. Note: The USB-C ports do not support video output.
- What You Get: Anker 332 USB-C Hub (5-in-1), welcome guide, our worry-free 18-month warranty, and friendly customer service.
Compare the specifications carefully
- Capacity: Choose enough space for the files you expect to carry.
- Read versus write speed: Read speed is not the same as write speed. A high advertised read rate does not establish how quickly the drive will save files.
- Compatibility: Check the manufacturer’s supported operating systems and any device-specific requirements.
SanDisk lists its Ultra Dual Drive Go with a manufacturer maximum read speed of up to 400 MB/s for listed capacities. That is a published maximum, not an independently measured result or a promise of the speed you will get on your PC.
For a different compact-drive example, SanDisk’s Extreme Fit USB-C Flash Drive data sheet lists up to 400 MB/s read speed for 128 GB–1 TB capacities and notes lower write speeds. These figures apply to the capacities and model described in that data sheet; they should not be transferred to other drives.
Rank #3
- Note: Not suitable for MacBooks released after 2023 or devices with a protruding front camera; Not applicable to full-screen or notch-style tempered glass screen protectors; Do not use on the rear camera of the phone.

3. FIDO2 USB security key: use a hardware sign-in option
A FIDO2 security key is a physical accessory used for account sign-in security when the account or service and the user’s setup support it. It is not a universal sign-in solution: check compatibility with the accounts you want to protect, and confirm which connector the key uses.
Plan for setup and recovery
- Check which of your accounts and services support the key.
- Choose USB-A or USB-C to match the devices where you will use it; check whether NFC matters for your other devices.
- Follow the service’s enrollment steps and set up its recommended recovery method. A key you have not enrolled—or cannot replace or recover from—may not help when you need account access.
Google’s Titan Security Key product page is one source for checking a particular key’s connector and compatibility details. Confirm the requirements for your own accounts before relying on any key.

4. USB-C Gigabit Ethernet adapter: connect to a wired network
A USB-C Ethernet adapter adds a wired network connection to a PC when you have a compatible USB-C port and an Ethernet cable. It can be useful where a wired connection is available or wireless networking is not the connection you want to use.
Check before buying
- Confirm the PC’s USB-C port and operating system are supported.
- Check the adapter’s Ethernet speed against the network equipment and service you use; a Gigabit-rated adapter does not make a slower network faster.
- If you also need extra USB ports or video output, compare a multiport hub rather than assuming a basic Ethernet adapter includes them.
Manufacturer examples include Anker’s USB-C Gigabit Ethernet Adapter and Logitech’s USB-C Ethernet Adapter. Check the specific model’s operating-system and speed specifications before choosing.

5. USB-C cable: match the connection to the job
A spare USB-C cable is a useful everyday accessory for connecting compatible devices or charging equipment, but cables with the same connector can support different capabilities. Choose one based on what you need it to carry—data, power, or video—and verify its specifications alongside those of the PC and connected device. The USB-IF’s guidance on USB 3.2 speeds makes an important point for data transfers: the connection’s speed is limited by the lowest-capability component in the chain.
If certification matters, the USB-IF Product Search is limited to products certified to bear its logo. The organization says listings are maintained by members and advises contacting a manufacturer about products absent from the list; an absent listing alone does not establish whether a product is suitable for your particular use.
