Intro
USB Power Delivery charging is coming to more and more devices, after is has been added to the USB standard along with the introduction of USB-C connectors. The standard allows devices and chargers to talk to each other and negotiate what sort of power devices need, while also talking to cables to see how much current they can carry. It’s been adopted as a universal way to charge many kinds of devices by the European Union, but some current devices support it already, even as just an alternative.
Why it is needed
Reason 1: less weight
When travelling it can replace multiple power adapters. Corona now means that i would travel with work and personal laptop, camera, phone and other gadgets. Take a look below: on the left is a 90W USB-PD charger that replaces all the chargers on the right, which are the dedicated chargers for 2 laptops, camera and phone (well this one is USB already). One of the reasons for choosing the Asus G14 as my personal laptop was that I can use it with a USB-PD charger.
The dedicated chargers are 4.5 times heavier than the universal one (245 grams vs 1115 grams). Yes, the weight of the bowl is substracted 🙂
Reason 2: easier to borrow a charger
From a friend, neighbour, colleague or stranger in a cafe. For the laptop, the phone or other things.
Reason 3: less stuff to swap around
The work one stays at work, the home one stays at home because you can use the same one for both work and personal devices. No need to carry your work laptop charger back and forth or buy 2.
Reason 4: cheaper
Dedicated chargers have inflated prices because they cannot be easily replaced, so of course the manufacturer asks for more.
