USB Power Delivery (USB PD) is a fast charging standard developed by the USB-IF organization. It can realize power transmission of up to 100 watts and can freely change the direction of power transmission. It is the current mainstream fast charging standard.
During the Spring Festival of 2017, the USB-IF organization has released an important update of USB PD 3.0, officially launched the PPS (Programmable Power Supply) charging specification, successfully compiled Qualcomm QC4, and has reached a consensus with the Tel Lab of the Ministry of Industry and Information Technology. The USB PD has quickly made a big progress and made significant progress.
Since Apple released the iPhone 8/8 Plus/X in the second half of 2017, the domestic USB PD fast charging industry has developed spurt and formed a huge market with a value of over 10 billion, and millions of upstream and downstream enterprises in the supply chain. Benefit from.
According to reliable sources, Apple has opened a new 18W low-power USB PD charger for the iPhone, and will be equipped with this charger for the next generation iPhone. Driven by Apple, the popularity of USB PD fast charging will reach a new height.
As of the end of March 2018, the number of members of the USB-IF organization has reached 1,020, and as the latest charging protocol, USB PD fast charging technology not only has related applications on the iPhone, but also is as much as the market. 25 Android models are used.
Apple Apple
Apple is not the first mobile phone brand to use USB PD fast charging technology on mobile phones, but it really takes the development of USB PD fast charging technology to a new height, accelerates the popularity of USB PD fast charging, and charges in 26 USB PDs. In the test of the device, the iPhone 8 Plus is well compatible.
Huawei
At the end of 2017, Huawei released the flagship model Mate 10. After testing, this phone has very good compatibility with the USB PD fast charging protocol. Several flagship models released later can support USB PD fast charging. Before this, in fact, mate 9 has already realized the application of USB PD fast charging technology, but it is little known.
Samsung
When there was no accident in the early days, Samsung Note 7 could support the USB PD fast charging protocol, and the charging power was also very high. Note 7 After the explosion, Samsung's mobile phone's charging power has become much more conservative, but the subsequent flagship models still retain the support for the USB PD fast charge protocol.
Millet
In May last year, I discovered the Xiaomi 6 hidden egg, which is able to support USB PD fast charging, and after the phone upgrade, it actually supports the USB PD PPS charging protocol. The later release of Xiaomi MIX 2, MIX 2S can also achieve USB PD fast charge.
Nokia
In the previous test, the ChargerLAB POWER-Z KM001 was used to monitor the Nokia 7 charging negotiation process. The mobile phone initially selects the 5V gear and then selects the 9V gear, which is to support the USB PD fast charging, but only the second voltage file. A charger with a 9V speed can achieve fast charging.
hammer
On November 7, 2017, Hammer Technology officially released the “Almost Full Screen†Nut New Machine PRO2 in Chengdu. After testing the charging head network, it was found that the 65W charger (USB PD protocol only) of Xiaomi notebook was used to charge the nut PRO 2 mobile phone, and the result was to support USB PD high voltage fast charging. The subsequent release of the Nut 3 has not been tested, and it is estimated that the USB PD fast charge will not run.
Sony
From mid-2017, Sony released XZ Premium, which has been tested to support the USB PD fast charge protocol. The XZ1 released at the end of the year also supports two fast-slave protocols, QC3.0 and USB PD. Not surprisingly, the upcoming SONY XZ2 should also support USB PD fast charging.
Meizu
Meizu is also a manufacturer that has applied USB PD fast charging on mobile phones. According to the test, both the Meizu Pro 5 and Pro 6 Plus models can achieve USB PD fast charging. It is said that the newly released Meizu 15 can also be compatible with the USB PD protocol, but further verification tests are required.
Razer
Razer released its first smartphone, the Razer Phone, equipped with a 4000mAh ultra-large battery that meets all-weather life and supports Qualcomm's latest QC4+ fast charging technology (USB PD+QC3.0 protocol). After the mobile phone is upgraded, the charging power can reach 22W.
In summary, it can be seen that almost all mainstream mobile phone manufacturers have already incorporated the USB PD fast charging protocol into the charging configuration of mobile phones (this is only part of the data), and more mobile phone manufacturers will follow this rhythm. There are also more laptops, tablets, game consoles and other devices that support USB PD fast charging.
USB type-c will also be the only interface for power and data transmission between electronic devices in the next decade. The situation of USB PD fast charging protocol is coming soon.
