If you mean “Warning: Never place/use the charger like this”, here is a detailed explanation you can use:
⚠️ Warning: Never Put the Charger Like This
Never place a charger under a pillow, blanket, mattress, clothes, carpet, or other soft/covered surfaces while it is charging. These materials can trap heat around the charger and device, increasing the risk of overheating, damage, or fire.
For safer charging:
- 🔌 Plug the charger into a proper wall outlet and avoid overloading the outlet.
- 🌬️ Keep the charger and device on a hard, flat, well-ventilated surface where heat can escape.
- 🚫 Do not cover the charger with clothing, blankets, pillows, or other objects.
- 💧 Keep the charger and charging connection dry and away from water.
- 🔥 Keep charging equipment away from curtains, paper, bedding, and other things that can burn.
- 🔎 Check the cable, plug, and charger for fraying, melting, cracking, or other damage. Stop using damaged equipment.
- 🛌 Avoid charging devices underneath bedding or on a bed/sofa; fire-safety guidance specifically recommends hard surfaces for charging.
- 📱 Use the manufacturer-recommended charger and cable, especially for devices containing lithium-ion batteries.
Why this matters: A charger normally produces some heat during operation. If you cover it or place it where ventilation is restricted, that heat can build up. An excessively hot charger, unusual smell, buzzing, sparks, or visible melting is a warning sign—disconnect it safely and stop using it.
A simple warning message would be:
⚠️ WARNING: NEVER COVER OR PLACE THE CHARGER UNDER A PILLOW, BLANKET, OR OTHER SOFT MATERIAL. KEEP IT ON A HARD, FLAT, WELL-VENTILATED SURFACE TO HELP PREVENT OVERHEATING AND FIRE.
