You’ll find a range of USB adapters and hubs to match different needs. Common types include:

• Simple converters: USB-C to USB-A (and vice versa) for plugging older accessories into newer ports.
• Multiport USB-C hubs: Combine HDMI for displays, SD/TF card readers, Ethernet, and multiple USB 3.0 ports. Many also support pass-through charging (Power Delivery), sometimes up to 100W.
• USB hubs: 4–10 port expanders (often USB 3.0) to add more USB ports; some are powered and include individual on/off switches.
• Video adapters: USB-C to HDMI or USB to HDMI to connect a monitor or TV, with options up to 4K at 60Hz.
• Wall chargers: Single or multi-port USB-C/USB-A chargers, including fast-charging blocks and charging stations.

Check the product specs for speed (e.g., 10Gbps), video support, and power ratings.

It usually comes down to shape and how it plugs in:

• USB-A: Larger, flat rectangle. It inserts one way only and is common on older laptops, desktops, and accessories.
• USB-C: Smaller, rounded oval. It’s reversible, so it plugs in either way. Many newer phones, tablets, and laptops use USB-C.

Quick tips:

• Match the port on your device to the plug on your cable/adapter.
• If your device has USB-C but your accessory is USB-A, a small USB-C to USB adapter can bridge them.
• For displays, look for USB-C to HDMI adapters; for data-only accessories, a simple USB-C to USB-A adapter or USB hub may be enough.

1. Identify your ports: Check if your device uses USB-C or USB-A (and what the other side needs).
2. Decide the job: Data only? Video to a TV/monitor? Ethernet? Charging? Pick an adapter or multiport hub that supports that task.
3. Check performance: For speed, look for USB 3.0/10Gbps. For displays, check HDMI resolution/refresh (e.g., up to 4K at 60Hz). For charging, look for Power Delivery and the wattage your device supports.
4. Consider power: If you’ll connect multiple or power-hungry accessories, a powered hub can help maintain stable connections.
5. Look for certifications: USB-IF certification can indicate standards compliance.
6. Read details: Review specs and customer feedback on the product page to confirm compatibility with your setup.

It depends on what you’re connecting and how many devices you’ll run at once.

• Bus-powered hubs draw power from your laptop or tablet. They’re compact and fine for low-power items like mice, keyboards, and flash drives.
• Powered hubs include their own power adapter (for example, 12V/3A on some models). They can help when you use several devices simultaneously or connect power-hungry gear, and they may reduce connection drops.

Consider a powered hub if you notice unstable devices, frequent disconnects, or slow performance when multiple accessories are attached. Always check the hub’s total power output and your accessory needs for the best experience.

• Confirm compatibility: Make sure the connector types match (USB-C vs USB-A) and the adapter supports your task (data, video, Ethernet, or charging).
• Try another port/cable: Test a different USB port, cable, or device to isolate the issue.
• Add power if available: If it’s a hub with a power adapter, plug it in—especially when using multiple accessories.
• Video checks: For HDMI, select the correct input on your display and use an adapter rated for the resolution/refresh you need.
• Reduce conflicts: Disconnect other high-draw devices and reconnect one by one.
• Review the product page: Look for any compatibility notes or setup tips in the description and Q&A. If problems persist, consider contacting support for further assistance.
