Affiliate Disclosure

Some links on this site are affiliate links. If you click one and make a purchase, we may earn a commission from Amazon Associates, eBay Partner Network, or partner brands (such as adapter manufacturers) at no additional cost to you. These commissions help keep this site free. Our recommendations are based on voltage and safety facts, not commission rates — we will never recommend an unsafe electrical setup to make a sale. Voltage and plug information is provided for general guidance; always verify your device's label and local outlet before use. This site does not provide medical advice; for CPAP or other medical equipment, consult your device provider.

General guidance, not certification

This tool provides general guidance only — not professional electrical, engineering, or safety advice. Voltage, frequency, and plug data can change and may vary by building, region, or individual outlet, including in hotels and older properties. Always check the printed label on your device or its power supply before plugging it in. When the label and our guidance disagree, trust the label. If you are unsure, consult a qualified electrician or the device manufacturer. You use this information at your own risk.
