USB-C plug USB-C (SuperSpeed USB 5Gbps) receptacle on a laptop. USB-C, or USB Type-C, is a 24-pin, reversible connector (not a protocol) that supersedes previous USB connectors and can carry audio, video, and other data, to connect to monitors, external drives, hubs/docking stations, mobile phones, and many more peripheral devices. It can also ...
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 USB-powered devices, it is 5 volts. Later, battery charging protocols such as Quick Charge by Qualcomm and USB Power Delivery started allowing charged devices to request different voltages suited for their needs, usually higher voltages to increase power without adding heat to the copper wires of the USB cable. In the past, "SuperCharge" by ...
Quick Charge requires both the power supply and the device being charged to support it, otherwise charging falls back to the standard USB ten watts. Quick Charge 2.0 introduced an optional feature called Dual Charge (initially called Parallel Charging), [4] using two PMICs to split the power into 2 streams to reduce phone temperature. [5]
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 vehicles, power ...
Charging a 12 V lead–acid car battery A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it.
[258] [c] Wireless charging has been widely adapted, allowing for intermittent recharging without wearing down the charging port through frequent reconnection, with Qi being the most common standard, followed by Powermat. Due to the lower efficiency of wireless power transmission, charging rates are below that of wired charging, and more heat ...
The railway's predecessor, the Staten Island Rail-Road Company, was incorporated on May 21, 1836. The charter called for the construction of a single or double-tracked line "commencing at some point in the town of Southfield, within one mile of the steamboat landing at the Quarantine, and terminating at some point in the town of Westfield; opposite Amboy."
