By way of example, a 150 volt PV array connected to an MPPT charge controller can be used to charge a 24 or 48 volt battery. Higher array voltage means lower array current, so the savings in wiring costs can more than pay for the controller. [citation needed] Charge controllers may also monitor battery temperature to prevent overheating.
Toshiba calls it USB Sleep-and-Charge. [85] On Acer Inc. and Packard Bell laptops, sleep-and-charge USB ports are marked with a non-standard symbol (the letters USB over a drawing of a battery); the feature is called Power-off USB. [86] Lenovo calls this feature Always On USB. [87]
A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage , amperes, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
WASHINGTON (Reuters) -The United States issued sanctions against a Russian judge on Tuesday for her role in the detention of human-rights activist Alexei Gorinov over his opposition to Russia's ...

Nottinghamshire Police said officers were called to Glasshouse Street, in Nottingham, at about 10:40 GMT on 9 December following an altercation between the driver and two passengers.
A ferroresonant transformer can operate with an input voltage range ±40% or more of the nominal voltage. Output power factor remains in the range of 0.96 or higher from half to full load. Because it regenerates an output voltage waveform, output distortion, which is typically less than 4%, is independent of any input voltage distortion ...
Qi (/ tʃ iː / CHEE) is an open standard for inductive charging developed by the Wireless Power Consortium.It allows compatible devices, such as smartphones, to receive power when placed on a Qi charger, which can be effective over distances up to 4 cm (1.6 in). [1]
