Firefighters have urged people to keep e-cigarettes away from flammable materials after a charger overheated and sparked a house fire.
A man was treated for smoke inhalation after the blaze in Llandybie, Carmarthenshire, on Friday night.
Mid and West Fire and Rescue Service said the charger had set fire to curtains.
Steve Davies, head of community safety, said it had seen "heightened numbers" of fires caused by the devices.
He added: "Although this was a minor incident, based on previous cases the consequences can be devastating."
