· Provide even more power, plus, more stabilize.
· Charge your device 70% faster than the standard 5W charging.
· One PD charger can do double duty or triple, even quadruple.
If you want to take full advantage of the fast charging function of your new USB-C devices, you will need to get a USB-C PD (Power Delivery) cable which has the Power Delivery protocol.
USB-C Power Delivery or PD might not be familiar to most people, but the truth is a fast charging technology, supported by certain devices, that delivers much higher levels of power than standard charging. In the old days, the mobile phone cannot watch movies when charging at the same time. But in the new generation of USB-C PD specifications, you can enjoy movies while charging. After all, surfing the Internet and watching great live streams while charging is already a part of modern life.
If you add a new way to charge your iPad/iPhone that uses a USB-C connection, and if you want to maximize the charging speed supported by the device and the power source you should get a PD charging cable. To get a Power Delivery cable means to recharge your iPhone X, iPhone 8, or iPhone 8 Plus up to 50% in around 30 minutes when paired with a USB-C to Lightning Cable. (It will take about 2 hours to charge the iPhone 8, and about 3.5 hours to fully charge your iPhone 8 Plus at the usual 4.85V/0.95A.)
To recharge your Google Pixel 2 or Google Pixel 2 XL up to 50% in 37 minutes pairing with a USB-C to USB-C PD cable. (A full charge for Google Pixel 2 XL is about 2.5hrs, which takes an hour and a half for the last 50%.)
*Charge speed varies on chargers/adapters, and cables. (Using a 45W charger and a PD charging cable for the test.)
The maximum charging power for USB C is specified as 100W. (The comprehensive protocol covers 5V/ 3A, 9V/3A, 12V/3A, 15V/3A, 20V/3A, 20V/5A.) Thanks to the e-marker*, it allows two devices to negotiate a power contract, so they can intelligently determine how much power can be pulled from the charger.
That means one single USB-C PD charger can charge your phone quickly, or something bigger like a portable games console, even your productive device like MacBook Pro. One PD charger can do double duty. Now you can take that charging speed with you in the car, in your office, or when you travel.
*e-marker, also known as electronic marker. It actually is a protocol controller, which includes the power supply, power receiving, and power transmitting capabilities of the product.This IC chip ensures speedy charging and prevents damage from delivering too much power.
Well, first of all, you need to bear in mind that ALL the connection process has PD function.
You have to make sure the source device, the connector, and the target device are well prepared.
That means you need to make sure you are using the
1) right device (supports PD/QC protocol),
2) right cable(with PD function),
3) and right charger(with PD logo) for the PD charging environment.
You know it is PD, and you know it is fast.
