Name the claimed function

Write down exactly what the accessory promises. Ask which field type, frequency range and operating conditions are addressed. A broad EMF label is not a specification.

Check the device setup

Compare dimensions, cable access, placement and the laptop manufacturer’s ventilation instructions. Ask whether test conditions match charging, wireless operation and the way you intend to use the device.

Compare documentation

Request the test report and note whether it covers the material, accessory or complete setup. Keep any claimed health outcome separate from a claim about physical performance.

Consider the whole workspace

Review desk layout and connectivity as well as accessories. Use the room explorer to record positions, or read our wired office guide. See computer accessory criteria.
