Inductive charging. The primary coil in the charger induces a current in the secondary coil in the device being charged. Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in ...
Quick Charge is a proprietary technology that can charge battery-powered devices, primarily mobile phones, at power levels exceeding the 7.5 watts (5 volts at 1.5 amps) supported by the USB BC 1.2 standard, using existing USB cables. The higher voltage available allows more power (watts) to be supplied through wires without excessive heating.
Universal charger or common charger refers to various projects to standardize the connectors of power supplies, particularly for battery-powered devices. Since the publication of the USB Power Delivery standard in 2012, and the USB-C connector in 2014, USB-C has become a widespread standard for charging mobile phones.
For the majority of images it will consume 60–80% of the power of an LCD. OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight, [39] while OLED can use more than three times as much power to display a mostly white image compared to an LCD.

Although Linux distributions are generally available without charge, several large corporations sell, support, and contribute to the development of the components of the system and free software. An analysis of the Linux kernel in 2017 showed that well over 85% of the code was developed by programmers who are being paid for their work, leaving ...

The Combined Charging System ( CCS) is a standard for charging electric vehicles. It can use Combo 1 ( CCS1) or Combo 2 ( CCS2) connectors to provide power at up to 350 kilowatts (kW) (max 500 A). [1] These two connectors are extensions of the IEC 62196 Type 1 and Type 2 connectors, with two additional direct current (DC) contacts to allow high ...
The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
