Qualcomm QC3.0 fast charging scheme should be the most supported fast charging scheme on the market at present, and it is also the one that consumers know best. From the earliest QC 1.0 to QC2.0 and now to QC3.0, the third generation fast charging scheme could not be sent out unconsciously. Although there are many fast charging schemes in the market, Qualcomm QC3.0 is still very popular with consumers.
QC 1.0: Supports charging power supply up to 5V/2A.
QC 2.0: compatible with 5V/9V/ 12V/20V four-level charging voltage.
QC 3.0: It provides flexible selection of voltage from 3.6V to 20V in increments of 200mV, so that mobile phone manufacturers can adjust the optimal voltage according to their own needs, achieve the expected current, improve charging efficiency, and reduce power consumption and heat generation. At present, there are LG G5, Xiaomi mobile phone 5 and so on. This is QC 3.0 fast charging standard and supports this protocol.
Second, MediaTek MTK:PumpExpress Plus
In the past few years, MTK was crushed by Qualcomm because of its backward fast charging technology. In recent years, PumpExpress technology began to appear, with a built-in PMIC power management integrated circuit, which allows the charger to determine the initial voltage required for charging according to the current. The pulse current command sent by PMIC is transmitted to the charger through Vbus of USB, and then the output voltage is adjusted according to this command, and gradually increased to 5V to promote the maximum charging current.

Third, Huawei FCP (Fast Charger Protocol)
As the world's largest telecom equipment manufacturer, Huawei has never fallen behind in technology. The previous Huawei Mate 8 and Glory 7, the latest Glory V8 and the FCP on Huawei P9 all belong to Huawei's own fast charging technology. In June this year, Huawei launched a glory mobile power supply with 10000mAh, which also supports this technology, with a maximum fast charge output of 9V/2A( 18W).
Fourth, BBK OPPO:VOOC flash charging technology
Charging for 5 minutes and talking for 2 hours is a very familiar slogan, which also includes the flash charging technology of OPPO mobile phone. As early as OPPO Find 7, we had already learned VOOC flash charging technology, and then N series and R series began to popularize this technology. Nowadays, the slogan of "charging for 5 minutes and talking for 2 hours" has become a brand symbol. Different from the above-mentioned fast charging technology, VOOC flash charging technology focuses on large current rather than high voltage. OPPO original fast charging head can support 5V/4A power output at most, and it can also achieve 5V/2A power output when plugged into a mobile phone that does not support VOOC flash charging.
At that time, the first generation VOOC fast charging standard of OPPO Find 7 could not separate the fast charging head from the USB cable, and it was relatively large. It was not until OPPO N3 and OPPO R5 introduced the second generation fast charging head that the volume compression was realized and the separable design was made. Of course, if the charging speed is improved, the safety will naturally be pushed to the forefront. OPPO applied for 18 patents and obtained a number of authoritative certifications including Swiss IEC. At the same time, it integrates the five-fold security protection technology exclusively developed by OPPO.
Verb (abbreviation of verb) vivo double-engine flash charging
Vivo and OPPO are two independent sub-brands of BBK, and both have their own flash charging technology. Vivo adopts dual charging chips and dual charging circuits, and is equipped with customized flash charging batteries, which brings twice the charging speed of ordinary mobile phones, and has a unique nine-charge protection system, which makes charging faster and safer. Judging from the original quick charging head of vivo X7Plus, the output power has two specifications: 9V/2A and 5V/2A.
