Introduction

Laptops are a must-have for people who often work outside. Thin and light laptops are easy to carry and their long battery life makes them more popular.

This time, ChargerLAB got the Huawei MateBook X Pro. The official claim is "Charge for 10 minutes to work for up to two hours on-the-go, with the laptop's premium, pocket-sized 90 W charger". So, let's take a look at the charging performance of this laptop.

Product Appearance

It is made of alloy and has a matte texture. It adopts a three-stage PCB design and weighs only 980g.

HUAWEI is printed here.

This is a 14.2-inch 2120 x 2080 resolution OLED screen with an ultra-high screen-to-body ratio of 93%, supporting a 120Hz refresh rate and a brightness of 1000 nit. This screen also supports touch controls. The camera is located at the top of the screen.

There is a power button that supports fingerprint recognition in the upper right corner of the keyboard. It has a large touchpad.

There is a round silicone pad on each of the four corners of the bottom.

It is only 13.5 mm (0.53 inches) at its thinnest point.

There are two Thunderbolt 4 ports and an indicator light.

The other side is the switch of the camera and the USB-C charging port.

The weight of it is about 985 g (34.74 oz), much lighter than other thin and light laptops.

This is the included 140W power adapter. It comes in pure white. The case is made of PC fire-retardant material and has a smooth surface.

It only has one orange USB-C port. The words “HUAWEI Super Charge” and “140W” are printed below the port.

The power adapter is designed with fixed prong.

The specs info are printed below the prong. Model is HW-200700CP0. It can support input of 100-240V~50/60Hz 2.5A. It can support output of 5V2A, 9V3A, 15V3A, and 20V7A.

The ChargerLAB POWER-Z KM003C shows the USB-C port can support UFCS, FCP, SCP, QC2.0, QC5, DCP, PD3.0, and PPS charging protocols.

And it has five fixed PDOs of 5V3A, 9V3A, 12V3A, 15V3A, 20V4.5A and a set of PPS, which is 3.4-21V4.5A.

The connector of the dual USB-C cable is made of PC material and is engraved with "7A".

The length of the dual USB-C cable is about 181 cm (71.26 inches).

The USB-C to USB-A adapter can connect USB flash drives, keyboards, and other devices.

Here are the included USB-C wired headphones.

Compatibility Test

We use some original chargers and some third-party chargers to test the compatibility of it.

Original Chargers

Use the original 140W power adapter to charge the MateBook X Pro, the real-time charging power is about 19.87V 6.84A 136.09W.

As you can see, there is no compatibility issue. The maximum charging power can reach 136.09W.

We have compiled the test results into a bar chart. Most chargers can reach their rated power.

Third-Party Chargers

We use some third-party chargers paired with the original cable to test the compatibility.

Use the SHARGE 100W charger to charge the laptop, the real-time charging power is about 20.06V 4.85A 97.35W.

As you can see, there is no compatibility issue. The third-party chargers tested can all reach the maximum output voltage they support.

We have compiled the test results into a bar chart. Most chargers can reach their rated power. The maximum charging power can reach 99.24W.

Using the original power adapter, the maximum power can reach 136.09W. The charging power of third-party chargers that support PD3.0 100W can reach 99.24W.

Full Charging Test

We use the original 140W charger to fully charge the Huawei MateBook X Pro. And put them into a 25°C (77℉) thermotank throughout the test.

The voltage is always about 20V. The charging curve can be divided into eight parts. In the first part, the power was about 80W for the first 3 mins. Then, the power increased to 136W and continued until 13 mins. The power then dropped to 58-78W and lasted until 22 mins. Then, the power increased to 136W and continued until 25 mins. The power then dropped to 90W and lasted until 31 mins. Then, the power increased to 136W and continued until 32 mins. Then, the power gradually drops to 120W and 100W in turn. The final part begins at 38 mins, and the power slowly drops to almost zero. It takes 1 hour and 35 mins to be fully charged.

From this chart, the MateBook X Pro can reach 50% in 27 mins and 80% in 44 mins. It also reaches 100% in 1 hour and 35 mins.

Temperature Test

We also recorded the highest temperature on the front and back after charging for 20 mins, 30 mins, and 50 mins.

20 Mins Charging

After 20 mins, the maximum temperature on the front is 38.2 °C (100.76 ℉). The heat is mainly concentrated in the middle area of the keyboard.

The back is 35.3 ℃ (95.54 ℉).

30 Mins Charging

After 30 mins, the maximum temperature on the front increases to 47.6 °C (117.68 ℉).

The back is 42.7 ℃ (108.86 ℉).

50 Mins Charging

After 50 mins, the maximum temperature on the front drops to 35.2 °C (95.36 ℉).

The back is 34.3 ℃ (93.74 ℉).

We know from this chart, that the temperature on the front is higher than on the back. The temperature is the highest at 30 minutes, which is 47.6 ℃. After 50 minutes of charging, the temperature has dropped to 38.2 °C. The charging power was higher than 100W most of the time during the temperature test. So, as an ultra-thin laptop, its heat dissipation performance is pretty good.

Summary of ChargerLAB

The case is made of alloy and has a matte texture. It adopts a three-stage PCB design. It is only 13.5 mm (0.53 inches) at its thinnest point and it weighs only 980g. It has two Thunderbolt 4 ports and a USB-C port. It has a battery capacity of 70Wh.

It is compatible with the 140W proprietary protocol and PD3.0 100W protocol. There are no compatibility issues. It takes 27 minutes to charge to 50%, but it takes 1 hour and 35 minutes to be fully charged. The temperature is the highest at 30 minutes, which is 47.6℃. But considering it is an ultra-thin laptop and has high charging power, its heat dissipation performance is still acceptable.
