Charging has changed quite a bit over time, and this is mostly due to the portable devices that we use becoming more powerful. In this case, it’s most true when it comes to smartphones. Smartphones are the one tech product that has the most eyes and ears towards it, as nearly every person now owns a smartphone and it’s one of the most accessible tech products on the market. Most notably, people are always looking forward to getting the latest Samsung phone or the new iPhone. Especially the new iPhone.
Advances With Specs
Of course, it’s not just limited to Samsung and Apple. There are a bunch of brands that release new phones every year. You’ve got LG, Sony, Google, and the highly established but at the same time new, OnePlus. Each of these brands is large and knows what the latest tech is to put into their phones. This rise in the competition made it so each phone has the best each year. The most notable part is always the camera for a phone. This year (2019), Apple made it very clear that their iPhone 11 Pro lineup was about the cameras, as their new iphone impact is now using three cameras.
Then there’s the usage of new processors each year. For Android smartphones, they’re going to be using Snapdragon processors, but for Apple, they always use a new Bionic chip. In addition to new processors, the use of more RAM has made it so that phones are snappier. Most phones are now using up to 12GB, which is more RAM than most people have with their computers or laptop.
The screens for our phones have also improved a lot. Most phones up until recently have used LCD screens. Now phones are using OLED screens, which are brighter, have more accurate colors that pop, and it works well with a notch. The cameras for our phones have also improved greatly, and now we’ve got phones that are using multiple cameras.
Higher Power Means More Demand
Combine all these latest features and what you end up with is a phone that uses a ton of power and because of that, they use bigger batteries. The first phone I ever owned was the Samsung Impression, it was one of those phones with a slide-out keyboard and it has a 1,000mAh battery. Phones are now having 4,000mAh batteries which are necessary to keep up with the demands of higher specs that phones now have.
Having a large battery is great, but at the same time, you have to get it back to its full power when it comes time to charge it. Standard charging for larger batteries such as the Samsung Galaxy’s Note 9 and Note 10 4,000mAh battery is not going to be enough to charge it fast enough if you’re still going about your day. If you’re a power user throughout the day of using your phone, meaning that you use full power brightness, lots of screen on time, watch many videos, and usage of the internet is high; then you’re going to run out of battery power either halfway or near the end of your day.
Power Delivery For All
In cases like these, there are two great solutions for charging your device. One is to use some sort of fast charging technology for your smartphone, and the other is to use a power bank or wireless charging coil. A fast charging technology that is most used with Android smartphone is Quick Charge, but even though Quick Charge is useful for charging smartphones with its 18W charging speed, you can’t use it to charge laptops. It’s simply not powerful enough. What is powerful enough is using Power Delivery. Power Delivery is a very powerful way to charge not only smartphones, but you can also use it to charge laptops, and that is why it’s growing so quickly. Many devices are compatible with it and this is mainly due to lots of portable devices using a USB-C port.
Power Delivery can output 100W of power, this covers a wide range of laptops, and that is why we have the MacBook using PD, some many Chromebooks use the USB-C port along with Power Delivery, and there are even some gaming laptops that use Power Delivery such as the Razer Blade Stealth. A gaming laptop being able to use PD is very surprising because they usually use chargers that are well over 100W of charging power. Of course, the most impressive part is the usage of Power Delivery is that it can be used with different types of chargers.
The most useful type of chargers that Power Delivery can be used for is power banks. This is because when it comes to charging laptops that use those charging bricks and have DC ports to charge, you have to search for an AC outlet to charge from. Now, with Power Delivery power banks, you can have a 20,000mAh portable charger that has a 30W PD charging speed or higher and charge your laptop wherever you are.
There are plenty of smartphones that are also able to fast charge using Power Delivery, but they still charge at a charging speed of 18W. The great thing though, is that even with an 85W PD charger, you can still use it to charge your smartphone, so you would only need a single charger to charge your laptop and smartphone.
Improvements With Power Delivery
Also, Power Delivery has two main improvements that it has undergone recently. The first one being those power Delivery chargers, such as a 61W PD charger can be very small because it uses a Gallium Nitride chip. The other improvement is that there are PD chargers that use two PD ports that can fast charge two smartphones at the same time, or charge two laptops at once; the great part about having two PD ports on a charger is that most of them have the ability to supply more power if you have just a single device charging.
