Is it dangerous to leave a cellphone charger plugged in without the cellphone?

Unplug and conserve

Unless it is defective, it is not dangerous to leave a phone charger plugged in an electrical outlet. But the transformer and circuit within the charger still draw current and dissipate a small amount of heat, so it is considered wasteful of electricity (and thereby damaging to the environment) to leave it plugged in when it is not charging a cell phone.
