Jumper Tech EZbook X3 Air Laptop in review: Appealing design meets reasonable price

Passively cooled Celeron. The Jumper EZbook X3 Air is based on much more expensive models with its flat construction and slim design. The metal housing provides a high-quality and robust impression. The test will show what the hardware can achieve in a device for about 350 Euros (~$410).

Jumper Tech EZbook X3 Air

In addition to the established brand names of large manufacturers, there are also many inexpensive laptop providers on the market that can offer extremely low prices and quite well designed devices. Mostly older hardware is used, which is only suitable for simple applications.

This also includes the Jumper Tech EZbook X3 Air, which we compared in our test with the competing devices listed below. Under each section you can add notebooks from our database for comparison.

Case - Sturdy metal netbook

Jumper makes the EZbook X3 Air case from metal. This makes the device look very robust and there are no defects in the workmanship. The screen can be folded back up to an angle of 180 degrees and the hinges are quite smooth. The screen is nevertheless reliably held in the set position.

Equipment - Jumper laptop with USB Type-C

The Jumper EZbook X3 Air offers a basically solid connectivity choice. Monitors can be connected via MiniHDMI and the USB type C port is also suitable for charging the notebook.

SD card reader

The memory card reader accepts microSD cards and achieves rather slow speeds with our reference memory card Toshiba Exceria Pro SDXC 64 GB UHS-II, which, however, corresponds to the level of our test field.

Maintenance

On the bottom side of the EZbook there is a space with a free M.2 slot for installing an additional mass storage device.

Warranty

The manufacturer grants buyers a warranty period of 12 months.

Input devices - Large ClickPad and QWERTY layout

Keyboard

The keys on the Jumper EZbook X3 Air offer a non-slip surface and a very palpable pressure point. While the arrow up and arrow down keys are only half the size, the scroll keys, End, Insert and Pos1 have been omitted completely. Due to the QWERTY layout, users also have to do without labeled umlauts.

Touchpad

As a mouse substitute Jumper uses a ClickPad, which is well suited for mouse pointer navigation. Right and left mouse clicks can be triggered by a light pressure in the lower corners and the pad also reacts reliably to touch gestures.

* ... smaller is better

Our measurements confirm that the X3 Air has a good contrast ratio of 1,291:1 and an equally good black level of 0.275 cd/m². Thus, colors appear well separated from each other and black image contents appear relatively saturated. Added to this is very good color-space coverages of 96% (sRGB) and 61% (AdobeRGB).

CalMAN analysis also shows that the display shows image content with too low a red component and too high a blue component.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
29 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 13 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 68 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
41 ms ... rise ↗ and fall ↘ combined↗ 21 ms rise
↘ 20 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 51 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (38.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 250 Hz ≤ 10 % brightness setting

The display backlight flickers at 250 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 10 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 250 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9600 (minimum: 5 - maximum: 142900) Hz was measured.

The IPS panel of the Jumper laptop has very stable viewing angles. Image content can be read even from very flat angles without being distorted or displayed with distorted colors.

Processor

The Intel Celeron N4100 used here is a low-cost processor from 2017. The four cores offer clock rates between 1.1 and 2.4 GHz, with maximum performance depending on the cooling. With its passive cooling, the Jumper notebook can maintain its performance evenly over a longer period of time in our Cinebench R15 endurance test. The results of the individual benchmarks also show that the performance of the CPU is on par with other laptops with this processor.

Graphics card

In the Jumper EZbook X3 Air, the internal Intel UHD Graphics 600 graphics unit is responsible for displaying image content. This is only suitable for applications with low demands on graphics performance, which means that waiting times can be expected even with simple image processing. In the benchmarks, the GPU achieves a slightly above-average result and can therefore lead our test field.

What performance other graphics cards offer can be seen in our GPU benchmark list.

Gaming Performance

The power of the X3 Air is only sufficient for very simple or old titles. For example, we were able to play the economic and already five-year-old Dota 2 Reborn smoothly, but more modern or more-demanding titles were not playable.

What gaming performance can be expected from Intel's UHD Graphics 600 is shown in our GPU games list.

Emissions - silent operation

Noise emissions

Since the Jumper EZbook X3 Air is passively cooled, there is no fan noise. We also couldn't perceive coil whistles or similar noises.

Temperature

Stress test
Stress test

In our test, the Jumper laptop warms up to 41.6 °C under load. Thus, it feels warm but can still be placed on the thighs, for example. During our one-hour stress test, the CPU reaches temperatures of up to 100 °C. Afterwards, the system runs somewhat sluggishly but stabilizes again quite quickly. Therefore, users only have to expect performance drops under longer loads.

Before purchasing the Jumper EZbook X3 Air, buyers should carefully consider the application for which the laptop is intended. If only simple office programs and the Internet browser are to be used for occasional work, the small notebook does a good job. Components such as WLAN, SSD and display reliably fulfill their tasks, whereby the latter also offers good brightness. On top of that, the case feels high-quality and offers an easily accessible slot for memory expansion.

The Jumper EZbook X3 Air is an affordable laptop with enough power for simple tasks.

In addition to performance sufficient for simple tasks, users must also live with the highly reflective screen surface. As a result, the notebook can hardly be used outdoors and even in closed rooms, for example, artificial light sources are reflected. The QWERTY layout of the keyboard may also not be comfortable for every user.

I made my first IT walking attempts on a 386 with 4 MB of RAM. After that followed various PCs and notebooks, which I looked after and repaired in my circle of friends and acquaintances. After an apprenticeship as a telecommunications systems engineer and several years of professional experience, I graduated with a bachelor's degree in industrial engineering. Today I live out my fascination for IT, technology and mobile devices by writing test reports. In my free time I like to devote myself to vegan cooking and spend time with my family, which includes a whole range of animal roommates.
