If you mean “Warning: never put the charger like this” and you want a detailed explanation, here is a clearer version:
Warning: Never place or use the charger in this position
Do not put the charger in a way that blocks ventilation, bends the cable sharply, covers the charging adapter, or places it near water, heat sources, or flammable materials. Incorrect placement can cause the charger to overheat, damage the cable, reduce charging performance, or create a risk of electric shock or fire.
Always place the charger on a dry, flat, and open surface. Make sure air can circulate around the adapter, the cable is not twisted or damaged, and the charger is connected properly to a suitable power outlet.
If the charger becomes unusually hot, smells burnt, makes unusual sounds, or shows signs of damage, stop using it immediately and replace it with a safe, compatible charger.
I can also make it into a short warning label, safety poster, or user manual style notice if needed.
