The “universal charge” for notebooks! How to choose a power bank that supports PD protocol?

Nowadays, more and more notebooks (mainly thin and light notebooks equipped with low-power processors) are beginning to support the PD protocol based on the USB Type-C interface, and obtain charging power ranging from 45W to 100W. In order to keep notebooks with uninterrupted battery life when going out long distances, power banks that support high-power PD protocols have also begun to spread. What issues should we pay attention to when choosing such products?

Emerging PD power bank

USB PD (USB Power Delivery) is currently the most versatile and the most popular charging technology. It supports 5V~20V voltage, 2A~5A current, and covers the power range of 10W~100W

From smart phones, tablets, Nintendo Switch to notebook computers, almost all of the new digital products support the charging function of the PD protocol, but the power that can be enjoyed varies greatly. In other words, if a power bank can support PD (hereinafter referred to as PD power bank), then it has the qualification of “universal charging”.

So, is the PD output power supported by the power bank more worth buying?

PD power bank output power

In the field of PD power banks, the common PD gears are mainly 15W~18W, 27W~30W, 45W, 65W and 100W. If you want to find a partner that can recharge your laptop at any time, it is recommended to choose a power bank that starts at the 45W gear. Only they can ensure that the power of the laptop can increase steadily while charging. If the output power of the power bank is less than the consumption of the notebook itself, the power of the notebook battery is likely to decrease slowly while playing and charging.

How much power is supported by the standard charging head of the notebook, we can choose the PD power bank with much power

It can be seen that, except for a very small number of products equipped with 45W H series processors, most of the thin and light notebooks choose to support 65W PD output power bank is sufficient
