Speaking of checkpoints for choosing a notebook PC, apart from whether the OS is Windows or Mac, everyone is concerned about the installed CPU and memory, the weight of the main unit and the number of inches of the display. And recently, "ease of charging" seems to be counted as one of them.

What should I be careful about when using a PC charger?

USB Power Delivery, also known as "PD," can be cited as a factor in determining how easy it is to charge. In the past, notebook PC chargers used to be genuine products that came with the product, but if it is PD compatible, you can use a general-purpose (of course PD compatible) USB-AC adapter.

Since it can be charged not only from the USB-AC adapter but also from a PD-compatible mobile battery, the mobility of the notebook PC will be greatly improved. The ability to share power with smartphones and tablets is also a big advantage.

However, it is not enough to just check whether the target notebook PC is PD compatible. The wattage of the USB-AC adapter and mobile battery purchased together is also important.

For example, when the Surface Pro 7's battery is exhausted, if the charger / mobile battery is 60 watts or more, the Surface will turn on at the same time as connecting, but if it is less than 60 watts, it will take a while from connection to power on. It seems that you will have to wait (10% charge required). It can be said that there are many situations where higher output is more useful.

However, if you use a charger / mobile battery of 60W or more, you need to be careful about the cable. There are two types of PD-compatible USB-C cables, one that supports 5A (ampere) and the other, and a 5A-compatible USB Type-C cable (up to 20V / 5A) is required for PD charging that exceeds 60W. ..

Even if you prepare a USB-AC adapter that supports 100W, if the cable does not support 5A, charging will be limited to a maximum of 60W. Use a 5A compatible cable for PD chargers over 60W.
