Samsung note10 supports three fast charge protocols, using ChargerLAB Power-Z KT001 protocol test on note10 original charger, tested to support AFC fast charge and DCP protocol. So it can be said that the Huawei super fast charge agreement is the same! Extended data: Each fast charge is not only different in power, but also different in various protocols. For example, the common PD protocol, QC3.0 protocol, and the various names named by mobile phone manufacturers themselves: supercharger, VOCO flash charge, etc., then what is the difference between these fast charges? PD protocol refers to the USB-PD protocol, which is a fast charge protocol proposed by the USB-IF organization, all known as USB Power Delivery, which can theoretically reach 100W. In addition to mobile phones, many devices such as laptops also use this protocol. In addition, all other fast charging protocols must follow the PD protocol, that is, other fast charging protocols are included in it.
This is because everyone uses the USB interface, so they have to follow their standards.
The most typical use of PD protocol is the iPhone, Apple since the iPhone 8 models, all support 18W fast charge, but need to be paired with 18W PD charging head.
QC fast Charge protocol, the full name of Quick Charge, is a fast charge technology released by Qualcomm, to today, has experienced 5 generations, came to QC 4.0. Because it is the leading brother of mobile phone chips, Qualcomm has long integrated the fast charge protocol in its own chip manufacturers, but many non-Qualcomm processor mobile phones can also support the QC fast charge protocol, because the PD fast charge protocol is compatible with the QC protocol.
QC 2.0, opens the era of high voltage charging, provides 5V, 9V, 12V, 20V four groups of voltage gear; QC 3.0 era, refined to 0.2V as a first gear adjustment; QC 4.0 supports 3.6-20V fluctuating voltage (interface requirements must be USB C); QC 4.0 is compatible with QC3.0 and QC2.0 on the basis of 4.0.
In addition to QC 4.0, which is only compatible with the PD protocol, QC 2.0, QC 3.0, and QC 4.0 are all backward compatible versions.
03 PE Protocol Introduced by Mediatek, the PE protocol, full name Pump Express, features a charger that allows it to determine the initial voltage required to charge based on current. In turn, it also experienced three generations of PE (power within 10W), PE (increased 12V, 9V and 7V three gears), and PE 3.0 (bypassing the charging IC to charge and reduce heat). Although the same chip manufacturers, but the PE protocol in addition to Meizu, few mobile phone support. The above are public ownership agreements, in recent years. Many mobile phone manufacturers have introduced their own private agreements. 04 OPPO VOOC flash charge As early as 14 years ago, OPPO launched VOOC 1.0, which is different from the mainstream fast charge using high voltage, VOOC flash charge uses a low voltage and high current scheme.
At that time, the 5V\/2A 10W charger was the main market, and the 5V\/4.5A 22.5w VOOC flash charge was definitely a new approach.
Compared to traditional high-voltage fast charging, low-voltage fast charging has better temperature control and higher efficiency, and the 3,000mah Find7 can charge to 75% in 30 minutes, remember that it was 2014. In addition, because the battery system, wire, charging head have been re-customized, so the general charger is not suitable for VOOC flash charge. VOOC flash charge also went through several versions, evolving to today's superVOOC. In September 2019, OPPO released the new superVOOC 2.0, the latest fast charging technology is also used in the OPPO Find X2 Pro, OPPO Ace2 and other models released this year.
superVOOC 2.0 uses a dual battery series scheme and a new charge pump technology to halve the voltage of the dual cell, taking into account efficiency and safety, and finally achieve 10V\/6.5A, 65W flash charge. Even when the screen is on, it can maintain flash charge. It is worth mentioning that superVOOC 2.0 technology has also made OPPO the first domestic mobile phone manufacturer to use gallium nitride charging head as a standard. Until the first half of this year, gallium nitride charging head has gradually become one of the selling points of many manufacturers.
05 Huawei SC\/FCP Protocol SCP is the full name of Super Charge Protocol, FCP is the full name of Fast Charger Protocol, both of which are Huawei's own private protocols.
The FCP protocol was born earlier, using a \"high-voltage small current\" scheme similar to QC 2.0 and PE protocols, with an output specification of 9V 2A 18W. After 2016, Huawei launched a new SCP protocol, using a \"low voltage and high current\" scheme similar to OPPO, which has the same benefit of increasing power and reducing heat. The specification of SCP is 4.5V\/5A or 5V\/4.5A, that is, 22.5W, which has been carried as early as Mate 9, and the recent Huawei P40 is also a 22.5W fast charge supported by this technology. Later, on the basis of this agreement, Huawei added charge pump technology, reducing the charging voltage to about 5V, while increasing the current from 4A to 8A, and achieving a 40W super fast charge. The latest P40 Pro and the 40W supported on the P40 Pro are based on this technology principle. In addition, there has also been a 65W super fast charge on Huawei Mate X, which is actually the same as oppo's idea of dual battery charging, but the difference is that each battery uses electromagnetic isolation to achieve the actual 60w charging speed. Overall, the development of fast charge technology in the past two years is still very rapid, many manufacturers have shown their own not yet mass-produced 100W technology, the upcoming Lenovo rescue mobile phone, has also been officially announced will support 90W fast charge. Before the battery material has not made new breakthroughs, the constantly improving fast charge technology is also the best choice for the current faster pace of life.
The supercharge charger is compatible with Huawei 10V4A SCP, 10V2.25A SCP, 10V2A SCP, 5V4A SCP, 9V2A FCP fast charge protocol and 5V2A normal charge.
10V4A SCP and 5V4A SCP must be implemented with Huawei 5A cables.
Huawei's Fast Charge Protocol is divided into FCP (Fast Charge Protocol) and SCP (Super Charge Protocol). The former was used more in the early days, belonging to the high voltage fast charge school, and now SCP is mainly used. At present, Huawei SuperCharge super fast charge products support up to 66W wired fast charge and 50W wireless fast charge.
The charger supports 5V2A, 4.5V5A, 5V4.5A current, so it doesn't matter if you charge other mobile phones that don't support fast charging, you can use it normally.
