The port can charge the battery and power the phone while it is connected to, for example, a hands-free solution in a car. The FastPort became the only way to get external power to the phones. Chargers comes in several varieties, from 12/24 volt DC to use in cars, to 100-250 volt AC to use elsewhere.
Other mobile phone power supply and charging standards have been implemented in other parts of the world (e.g., Korea and China). Proposals for a global/industry-wide mobile phone charging solution have also been promoted by the International Telecommunication Union (ITU) and by industry organizations GSMA and OMTP. The ITU and the GSMA/OMTP ...
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.
The throughput of each USB port is determined by the slower speed of either the USB port or the USB device connected to the port. High-speed USB 2.0 hubs contain devices called transaction translators that convert between high-speed USB 2.0 buses and full and low speed buses. There may be one translator per hub or per port.
The device is the first flagship phone by Samsung to support Qualcomm Quick Charge 2.0 for fast charging up to 15 Watts. [ 14 ] The Note 4 features a USB 2.0 charging port instead of USB 3.0 (as was in the Note 3 and S5 ), in favor of a new feature called Fast Charge [ citation needed ] , which Samsung claims can charge the phone from 0% to 50% ...
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]

Because the same five-pin Micro-USB port is also typically used for charging the device, the sink is required to provide power to maintain the state of charge (or even recharge) while it is being used (although this is dependent on the power available being sufficient e.g., MHL 2 & 3 provide a minimum of 4.5 W / 900 mA, while superMHL can ...
