Literally, fast charging is easy to understand, that is, speeding up charging phone. How to realize it? The principle is also easily understood. By means of chipset, fast charging adjusts phone’s input voltage and current value so as to reduce charging time. It is common to speed up charging phone through three methods including increasing voltage constant current, low voltage and high current and high voltage and high current.

As the sealed phone design, the battery can not be exchanged. Moreover, the battery technology is not broken through yet, so it can not stand by for a day in the case of intensive use and there are usually some people using power bank to charge phones. However, fast charging can reduce charging time, enhancing user experience effectively.

Wanna charge your phone fast? What you should do is to select the matched charging device for your own mobile devices, because the fast charging standards are different and the power chip management is various. If power adapter does not support fast charging, the output voltage is not up to fast charging standard. In other words, special cable, special plug and special device are dispensable.

There are a number of wireless fast charging technical standards now and the most popular standard is still Qualcomm Quick Charge and USB-C Power Delivery (USB-PD).

At MWC Exhibition in Barcelona on Feb. 25th , 2019, the subsidiary Qualcomm Technologies, Inc. of Qualcomm Incorporated（NASDAQ: QCOM）released Qualcomm® Quick Charge™ technology for wireless charging, providing wireless charging industry with the company’s multi-year accumulated fast charging technical innovation in order to make consumers wireless-charge devices fast, safely and effectively.

The charger equipped with Quick Charge can provide more power in the connection with compatible devices so as to make charging speed faster. As one of the most wildly used fast charging technologies, Quick Charge is adopted among your favourable phones. If your smart phone is compatible with Quick Charge 3.0, it can charge your phone up to 80% electric quantity within only 35 minutes.

*Charging speed is four times faster than the standard 5W charger. Qualcomm® Quick Charge™ uses 2750mAh fast charging battery in closed test.

USB-C Power Delivery is a fast charging technology which can provide more power than the traditional charging method and is supported with multiple iOS/Apple and Android/Google/Samsung devices.

*With the use of Apple USB-C converting Lighting connection cable, USB-C PD can charge your iPhone 8 or advanced version up to 50% electric quantity within 30 minutes. Charging varies depending on the environment and the actual results may vary.

Although the transfer between current and electromagnetic field may conduce some power loss, 70% - 80% input power can still be transferred while wireless charging.

The charger’s coil accounts for a large proportion of its efficiency. The excellent design and high-quality components can reduce energy loss. The cheap and uncertified wireless charger may be made of unqualified materials and components, which is low in efficiency and unreliable in use hence affecting battery service life. Therefore, we suggest users to select wireless charging devices discreetly.

It is common to be heated for your charger and smart phone in charging with fast charging technology. In order to guarantee your device free from dangers, we suggest you to use the optimal wireless charger authorized. If so, there is no risk for fast charging as charging standard.
