[smartPC사랑=임병선 기자] Since the endemic, the number of people using various electronic devices outdoors has increased significantly. At the same time, the number of people purchasing ultra-light laptops and UMPC game consoles has also increased. In particular, as the performance of ultra-light laptops and UMPC game consoles improves, their popularity has increased as they allow people to easily work or play games outside.
The problem is that there is a lack of power when using ultralight laptops and UMPC game consoles outside. For general document writing or watching videos, it can be used for more than 5 hours, so there is no problem, but when playing games, the battery quickly runs out. Most UMPC game consoles can only be used for about 2 to 3 hours when running on batteries, and cannot be used for even 1 hour when using high-performance turbo mode.
Therefore, if you want to enjoy playing games outside for a long time, you need an adapter that supports high-output charging. In response to this demand, ultra-small adapters capable of 100W PD (Power Delivery) charging have also been released recently. However, it is not easy to find an outlet outside. To use an outlet, you have to go into a place like a cafe, but even in cafes, most of the seats with outlets are already occupied by someone else. So what if there was an auxiliary battery that supports PD charging?
Check PD charging support
First, let’s find out whether the ultralight laptop or UMPC game console you use supports PD charging. Most UMPC game consoles support PD charging, and most ultra-light laptops will support PD charging if they were purchased within 2 to 3 years.
To check whether PD charging is accurate, check the specifications of your laptop. Some laptop input/output terminals are marked as capable of PD charging, so you can easily check. Also, since PD charging is also possible with a Thunderbolt terminal, check whether there is a Thunderbolt terminal. If the device you want to use externally supports PD charging, you can use a PD charging adapter as well as a PD charging auxiliary battery.
Next, let’s check the PD charging output. PD charging output is divided into 10W, 18W, 36W, 60W, 100W, and 140W. Four voltage specifications are used: 5V, 9V, 15V, and 20V, and different outputs are provided depending on the requirements of the connected device. The connection terminal is currently using a USB Type-C terminal to unify the specifications.
Check if your device supports PD charging.
Choosing a PD charging auxiliary battery
Let’s check what to check when choosing a PD rechargeable auxiliary battery. First, you need to check the maximum PD charging output supported. If PD charging output is low, laptops or UMPC game consoles cannot be properly charged. If the PD charging output is low and used while charging, the battery will only shrink rather than charge. Therefore, if you are looking for a auxiliary battery for a laptop or UMPC game console, make sure that the PD charging output supports at least 100W.
Second, you need to check what the capacity of the auxiliary battery is. If the auxiliary battery capacity is low, it will not be able to properly charge your laptop or UMPC game console. Although it can charge a smartphone with a relatively small battery capacity, it is not suitable for charging a laptop or UMPC with a large battery capacity. Therefore, if you are looking for an auxiliary battery to charge a laptop or UMPC game console, choose a product with 20,000mAh or more.
Lastly, is whether or not it supports multi-charging. These days, it’s hard to find an auxiliary battery that can only charge one battery, but if you want to charge a variety of devices, you need a product with at least three terminals. Also, make sure the maximum output exceeds 100W. If the maximum output is around 100W, you may not be able to charge other devices while charging a laptop or UMPC game console.
PD charging output must support 100W.
Recommended PD rechargeable auxiliary battery
Anker 737 power bank auxiliary battery
The PD charging auxiliary battery recommended by the reporter is the Anker 737 power bank auxiliary battery. It is also a product that has already become a hot topic among many people due to its powerful performance. It has a large capacity of 24,000 mAh, supports the latest PD 3.1 charging standard, and has a maximum output of 140W. It is capable of charging not only UMPC game consoles, but also ultra-light laptops, gaming laptops, and MacBook Pros.
It is equipped with three input/output terminals: USB Type-C x1 (In/Out), USB Type-C x1 (Out), and USB Type-A x1 (Out). The maximum output per terminal supports 140W for USB Type-C and 18W for USB Type-A. You can charge both a UMPC game console and a smartphone while charging your laptop. It weighs about 630g, and although it is heavier than a regular auxiliary battery, it has the advantage of being able to serve as a substitute for an outlet and even being carried on an airplane.
There are buttons on the side to control the display.
It has three input/output terminals.
The actual weight was measured at 626g.
A dedicated pouch and one charging cable are included.
There is plenty of space even if you put all the Anker 737 power bank auxiliary batteries and cables.
There is a display at the top that allows you to check the status of the auxiliary battery. You can easily check the remaining battery capacity through the display, and it also indicates which terminal is currently being charged.
In particular, it is convenient because it displays how many watts are being output from the currently connected terminal, how much more the auxiliary battery can be used in the current charging state, the product’s temperature, and the battery cycle. It also has the convenience of rotating the display position 180 degrees when the auxiliary battery is rotated 180 degrees.
The current remaining battery capacity is displayed as a graph on the display.
You can also check the product temperature, battery status, and battery cycle.
You can also leave the display on all the time. However, it is not recommended because it drains the battery so quickly.
I tried connecting it to ASUS ROG Ally. It charges without any problem.
You can use it comfortably even when connected to a gaming laptop that supports 100W PD charging.
You can charge your laptop, UMPC game console, and smartphone at the same time.
It tells you how many watts are being output at the currently connected terminal.
