No load power
![The world's five largest handset makers introduced a new rating system in November 2008 to help consumers more easily identify the most energy-efficient chargers](/Images/godic/202501/30/PSU_no_load_5_star_rating_chart1718.png")
No load power consumption is the electric power consumed by a power charger when it is plugged into a wall socket but without the mobile phone or other handheld device being connected. Furthermore, it must be switched on at the plugs.
This wasted power is often incorrectly called standby power, which actually refers to the power consumed by a power adapter when a device such as a TV, DVD recorder or audio system is in a low-power mode. The power consumed in standby mode is used to maintain system functions such as responding to remote control, or a digital clock, whereas true no-load energy as consumed in a power charger does nothing of use.
