Enter the exact AC INPUT range, frequency, plug and grounding requirement. The result separates blocked conditions from missing information.
Use the device compatibility screening
How to interpret the result
The screening order is supply voltage, frequency, physical connection, protective earth, then AC load. Missing inputs stay unresolved. Heating, motor and medical equipment require manual review. The tool never issues an electrical safety certification.
A practical example and limit
A 120V-only device entered for the Philippines is blocked because the researched reference is 230V, even when an A/B-looking plug is selected. A broad 100–240V label can clear only the voltage field; the tool still needs exact variants, protective earth and AC ratings. An unknown or source-disputed value produces ‘needs confirmation,’ while high-heat, motor and medical uses produce manual review. The tool does not simulate a certified adapter product.
Before connecting anything
Read the exact appliance AC INPUT label, destination outlet voltage and plug variant. Check a grounded path and the lowest rated AC connector. If the result says blocked or needs confirmation, leave the setup unplugged until the missing point is resolved.
