What is PD?
The rise of the USB-C is changing smart devices charging in a fascinating way. Both Major smartphones and laptops manufacturers are integrating USB Type-C plugs, allowing cross-device charger sharing. Therefore, you can simply charge your phone with your laptop charger, and vice versa.
Power delivery (PD) charging is basically a fast charging protocol which is making use of the great functionality and universality.
HOW DO WE MEASURE POWER?
Before we talk about advantages of USB-C PD would bring, let’s see how Electric Power is measured. Electric power is the relationship between power “P” (how fast electricity is transferred), current “I” (how much electricity is flowing), and voltage “V” (electric pressure).
As you could see from the table below, USB 3.1 devices provide a minimum of 500mA at 5 volts. This increases to 900mA with a USB 3.1 port. USB Type-C ports can be configured in fast charging modes at either 1.5 or 3.0A for more power, and power capabilities have been extended up to 15W, while USB Power Delivery is a separate specification that can work across USB 2.0 and 3.0 ports and cables and able to deliver a maximum current of 5A, negotiable power up to 100W.
THEN, HOW MUCH POWER DO YOU, OR YOUR DEVICE NEED?
What do I get with USB Power Delivery?
Basically, you will enjoy;
HIGHER SPEED – MORE EFFICIENT POWER – BETTER SAFETY ASSURANCE
USB Power Delivery, or PD, is designed to be a more universal charging standard that allows a range of devices, not just smartphones, to charge quickly over a USB connection. It enables a wide range of devices to share chargers and even power each other seamlessly.
PD has been called the future of charging because leaders in the tech industry like Apple and Google have moved towards this universal style of charging for their latest devices because it has proven to be a safe and efficient way to push the limits of voltage and current to boost energy flow to our peripherals and computers.
Enable higher power delivery (70% faster than standard 5W Charging)
Charge larger devices, like tablets and laptops
Allow for broader and more optimal use of power sources via Fast Role Swap
Support extended messaging (28 Bytes in USB PD 2.0 and 260 Bytes in USB PD 3.0)
Enhance bus utilization so Improve battery management
Deliver exact power required to avoid damage to circuitry
TO BE MORE SPECIFIC, BELOW ARE SOME EXAMPLES OF USB POWER DELIVERY ADVANTAGE:
Enables new higher power use cases such as USB bus powered Hard Disk Drives (HDDs) and printers. This eliminates the need for a separate power brick.
A monitor with a supply from the wall can power, or charge, a laptop while still displaying.
USB power bricks or chargers are able to supply power through a laptop’s USB ports.
Laptops and USB power bricks can provide higher power to battery powered devices (not currently defined by USB).
Battery powered devices can get increased charging current from a hub and then give it back temporarily when the user’s HDD requires to spin up.
POWER WITH NO COMPROMISES.
The Power delivery charging doesn’t require any proprietary gear, so you can simply plug your big backup HDD which normally requires external power source directly to your laptop with only one cable and get even faster data transfer rate. Or quick charge your phone while transferring data with no interference at all. On top of that PD Optimizes power management across multiple peripherals so each device will draw only the power it requires for the current process i.e. your HDD won’t draw power unless it is spinning.
PD HAS NO BORDERS.
One of the most interesting things about PD is that the power direction is no longer fixed. you can use your portable power banks to charge your laptop while charging your mobile phone from your laptop. Not only that but you can also charge your Bluetooth headset from your phone.
POWERFUL YET CONTROLLABLE.
We all heard about the melting phones and exploding batteries these days while PD provides an intelligent way to eliminate this fear once and for all. In addition to the previously mentioned USB-IF compliance, PD charging also offers a flexible and smart way of system-level power management through optional hub communication with the PC. As well as low power compatibility hence, you can now charge your headset with your laptop charger.
Does my USB-C accessories supports USB Power Delivery?
There is a little confusion to be cleared up with the latest USB Type-C standard. Even though new phones sporting Power Delivery have a Type-C port, the two aren’t the same when it comes to charging power.
Not all USB-C accessories support USB Power Delivery, which caters to much higher power ratings than typical smartphone-based charging designs, as it’s intended to power hard drives, printers, and displays, as well as larger portable electronics like laptops.
USB-C Controllers; Enable up to 15W of power along with the reversible plug orientation and cable direction USB-C offers
USB-PD Controllers; Fully integrate the power path enabling up to 100W of power with alternate models such as DisplayPort video and Thunderbolt
