No, absolutely not. Plugging a 110V appliance into a 220V outlet—even with a plug adapter—is extremely dangerous and will almost certainly destroy the appliance immediately.

Here’s why:

• Double Voltage Overload: A 220V supply delivers twice the electrical pressure the appliance is designed to handle. This causes excessive current flow, overheating, and rapid failure of internal components.
• Instant Damage: Motors, heating elements, and circuit boards can burn out within seconds, often accompanied by smoke or sparks.
• Fire Hazard: In severe cases, the appliance may catch fire or cause an electrical short, endangering people and property.

Solution: To use a 110V appliance in a 220V country, you must use a voltage converter (step-down transformer) that reduces the input voltage from 220V to 110V. Ensure the converter's wattage rating exceeds the appliance’s power requirement (e.g., a 1500W hair dryer needs at least a 1600–2000W converter).

Important Note: Plug adapters do not convert voltage—they only adapt the plug shape. Always check your appliance’s voltage rating before connecting it to any foreign power source.
