PD20W refers to the maximum output power of 20W fastCharging protocol powerport Wireless charging , belongs to one of the USB PD (USB Power Delivery) standards. With the continuous development of smart phones and laptops, PD charging has gradually become a mainstream fast charging method for powerport wireless charging.
pd20w indicates the 20w fast charge. pd refers to pd fast charging, that is, USB-PD, which is a fast charging specification formulated by the USB-IF organization and is the mainstream fast charging associationIt is output by Type-C interface. The USB-PD fast charge protocol can increase the transmission of power through USB cables and connectors, and expand the power supply capacity of the cable bus in USB applications, so as to achieve the purpose of increasing the charging voltage or current.
WPD (20W Power Delivery) is a standard for the transfer of power between chargers and other devices, supporting up to 20 watts of power output. It can implement power transmission through the USB-C interface, but not all devices that support the USB-C interface support the 20WPD standardIt can only be used if the device itself supports it. The 20WPD standard supports bidirectional power transmission and a variety of power output modes, allowing you to automatically adjust power output as needed.
PD20W refers to a fast charging protocol with a maximum output power of 20W. Fast charging refers to the transmission of electric energy to the battery at a faster speed through a specific charging technology, so as to achieve a faster charging speed.
pd20w fast charge means Apple 20w fast charge. The Apple 20WPD charger output supports two voltage gears of 5V/3 and 9V/22A, and the maximum output power is 20W. Per outputThe principle of reducing half and doubling the output current, the actual voltage current of the mobile phone battery is 5V/44A. Demo model: Iphone 12 System version: iOS14 pd20w Fast charge means Apple 20w fast charge.
Smart phones: Most mobile phones that support the PD protocol can use the PD20W charging head for fast charging. Tablets: Many brands of tablets support PD20W fast charging and can also use PD20W charging head for fast charging. Laptops: Most laptops that support the PD protocol can use the PD20W charger for fast charging.
If you use the slowest 5W charger, that is, 5V1A, it takes 10 hours to be fully charged, and the fastest you can use the 18W charger to be fully charged in nearly 3 hours, mainly according to the maximum support charging power of your mobile power supply.
Input: 100-240v~50/60Hz, that is, the voltage is within 100V-240V (and 50-60HZ), and the current should reach 65mA will do. If the voltage is too high, the charger is easy to damage, too low to meet the output requirements. Output: 5V ~1000mA, the output value of 5V and 1000mA is specified that the electrical appliance must be 5V, and the current does not exceed 1000mA.
1, PD20W refers to the maximum output Power of 20W fast charging protocol, belongs to the USB PD (USB Power Delivery) standard. With smartphones and pensWith the continuous development of notebook computers, PD charging has gradually become a mainstream way of fast charging.
2, PD20W is a Power Delivery (power transmission) technology based on the maximum output power of 20 watts of charging specifications. It is mainly used in power equipment such as chargers, mobile power supplies and data cables to improve charging efficiency and speed.
3, pd20w refers to 20w fast charge. pd refers to pd fast charge, that is, USB-PD, which is a fast charging specification developed by the USB-IF organization and is one of the mainstream fast charge protocols.Output through the Type-C interface. The USB-PD fast charge protocol can increase the transmission of power through USB cables and connectors, and expand the power supply capacity of the cable bus in USB applications, so as to achieve the purpose of increasing the charging voltage or current.
4, pd fast charge and usb fast charge difference mainly lies in the output power, support voltage and current range, two-way power supply and compatibility. 20WPD (20W Power Delivery) is a standard for the transfer of power between chargers and other devices, supporting up to 20 watts of power output. It can be done via USB-ort wireless charge volume to achieve high power output, change the industry design and manufacturing scheme, change consumer habits.
2, recently, the Geek's Choice received the powerport wireless charger a charging black technology AnkerPowerPort AtomPD 1 charger from Anker, which is also the first time GaN (gallium nitride) material applied to the field of consumer electronics. GaN material may be a little strange to you, it is a new type of semiconductor material,Previously, it was mainly used in new energy vehicles, rail transit and other fields.
3, gallium nitride charger because of its unique semiconductor material characteristics, such as high temperature resistance, high power and small size, compared with traditional silicon-based chargers, show the powerport wireless charger significant advantages. It can withstand higher power pressure and has stronger conductivity, thus achieving higher charging efficiency, and is commonly found in devices that support fast charging. However, the price of gallium nitride chargers is relatively high, due to the increase in technical difficulty, the higher the power, the price rises accordingly.
4, purpleM 33w Gallium nitride charger advantages of gallium nitride black technology, Gallium nitride is currently the third generation of semiconductor materials for the development of micro-electronic components. With high temperature resistance, acid and alkali resistance, high strength and high hardness characteristics. Its main advantages are low loss and high switching frequency. On the one hand, the advantages of low loss can reduce the heat of the charger, on the other hand, the high switching frequency can reduce the transformer and capacitor volume.
5, this must tell you about the working principle of the charger, in general, the structure of the charger includes high voltage coil, iron core, low voltage coil and rectifier circuit. The phone is connected to a low-voltage charging port,When playing with the phone charging, it will increase the charging current of the phone. At this time, under the action of high temperature and current, the aging of the battery itself is prone to abnormal accidents.
