Before you buy

Check the connection before the checkout

Matching shapes are only part of compatibility. Keep your device model and the manufacturer's specifications close by.

Identify the exact device

Note the device model, generation and operating system. Check the accessory manufacturer's compatibility list rather than relying on appearance.

Separate connector from capability

A connector type does not establish charging power, data speed or video support. Compare the stated capabilities of the device, accessory and cable together.

Match power requirements

Check the required input, charger output, plug type and supported charging protocol in the manufacturer specifications.

Check what is in the box

Confirm whether cables, power adapters, batteries, mounts or receivers are included, and what you need to supply separately.

Review setup and ongoing requirements

Look for network, software, account, subscription and installation requirements before adding a device to your setup.

Your buying workbench

Check the whole connection

Plan the device, ports, cable, power and software together. A connector shape is only the starting point.

Laptop hub and docking setup

Define the displays, peripherals and charging you need.

Build your list

  • Compatible hub or dock
  • Required power supply
  • Suitable cables

Confirm before buying

USB-C shape alone does not guarantee video output, charging or multi-display support.

Multi-device charging

Compare power allocation for the actual combination of devices.

Build your list

  • Compatible charger
  • Cables rated for the intended use
  • Device-specific adapters if required

Confirm before buying

A charger’s total wattage is not a promise of that output from every port at once.

Monitor and display connection

Check the complete video path.

Build your list

  • Supported video output
  • Appropriate adapter or dock
  • Matching display cable

Confirm before buying

An adapter is not necessarily reversible. A display connector does not establish the supported mode.

Cable selection

Match both ends and the required capabilities.

Build your list

  • Cable with the right connectors
  • Required length
  • Rated adapters if needed

Confirm before buying

Two cables with the same connector shape can support different functions.

Audio connection

Choose for your source, listening device and controls.

Build your list

  • Compatible audio device
  • Correct cable or adapter
  • Required power source

Confirm before buying

A physically matching audio plug may not support every microphone or control function.

Desk organization

Plan cable routes and usable workspace before adding accessories.

Build your list

  • Suitable stand or organizer
  • Cable-management pieces
  • Required mounting accessories

Confirm before buying

A dimensional match does not establish a supported load or mounting connection.

The power calculator checks arithmetic only. It cannot certify compatibility or safety. Verify the exact charger, cable, device, hub and simultaneous port-allocation specifications.
