Jumper EZbook X3 Review: Ancient technology meets wobbly chassis

Some money just isn't worth spending. Naturally, a small amount of money only gets you a small amount of notebook. Jumper's creation, which they are selling for well under $300, cannot shine in any area. The weak workmanship, bad input devices and slow hardware are some of the things we wouldn't wish on anybody.

Jumper EZbook X3 13.3-inch FHD: Slow, ancient hardware in wobbly chassis

There's a new offer in the low-cost segment: The Jumper EZBook X3 is currently available for $250 and even has a Windows license. It is equipped with an old Intel Celeron N3350 processor - the rest of its hardware seems fairly up to date: an anti-glare IPS Full-HD display and an M.2 2280 slot for expanding storage capacity. What more could you want for a price like this?

The competition in the price segment below $300 is far and between. Manufacturers that address the low-cost segment do so with very few models only. There are some Medion and Lenovo devices, as well as LincPlus. The Akoya E4253 is most promising from a technological perspective - its Pentium N5000 processor is more modern and faster than the Celeron versions in other devices. The cheapest competitor is the IdeaPad Slim 1-14AST-05, whose performance, however, is not a lot better than that of our test unit (A6-9220e). Chuwi LapBook Pro and LincPlus P1 both have a better quad-core SoC and a reflective Full-HD IPS display.

Case & Connectivity

The manufacturer obviously did not pay much attention while developing this device. We don't think we've ever laid our hands on a more flexible case. It was probably supposed to be as thin and light as possible - to which the quickest solution is to choose simple, cheap plastic. 

The lid is also made of plastic, although it is significantly more solid than the base. The hinge gives a bad impression: Every time you move the screen, the back of the base unit gets warped.

The Jumper EZBook X3 does not have any maintenance options and RAM is soldered on. However, you can install a SATA SSD via the M.2 2280 interface through a hatch on the bottom of the base unit. 

The port selection is rather disappointing as well, although at least there is a microSD card reader available. However, this must have a USB 2.0 interface as it has very slow transfer rates. Bluetooth is included but limited to the old 4.1 standard.

Input Devices

The flexible base is bad news for the input devices: The keyboard is quite bouncy - particularly towards the center. The material gives way as soon as the pressure increases slightly. The ClickPad's disappointing pressure point makes this even more apparent, since it requires more pressure to trigger an input.

Even the moderate travel and spacious layout cannot really make up for this. The LincPlus offered the best input devices of our comparison field.

Display

Pixel array
Pixel array

The anti-glare 13.3-inch panel has a resolution of 1920x1080 pixels and offers a decent contrast ratio of 1045:1 and a good color display. The screen does not use PWM to regulate the brightness.

The 60-Hz IPS display has stable viewing angles and an even brightness distribution. There is some clouding around the edges, although this is only noticeable on a black screen. Brightness is below average - all our test unit's competitors offered better luminosity. That's why the matte panel is of no real use in direct sunlight and becomes hard to read in bright daylight. The best panel is that of the Medion Akoya E4253. It is matte and sufficiently bright - but only has a low contrast ratio.

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
33 ms ... rise ↗ and fall ↘ combined↗ 21 ms rise
↘ 12 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 240 (maximum) ms. » 86 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.5 ms).
       Response Time 50% Grey to 80% Grey
34 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 12 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. » 27 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (39 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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17886 (minimum: 5 - maximum: 2500000) Hz was measured.

We would even recommend buyers to perform a calibration: The EZBook's ex-works DeltaE Grayscale result was 10! Our calibration brought it down to 0.9. The panel can display colors quite precisely after all.

Performance

DPC Latency with issues
DPC Latency with issues

The Jumper EZbook X3 (13.3 inch) is only available with a Celeron N3350 and 6 GB of RAM. The dual-core SoC, made for affordable low-end notebooks, is suitable for very simple areas of use such as writing emails, browsing or watching short videos.

But even this could tax the chip and slow eMMC storage. 5 browser tabs and the performance is brought to its knees. Even loading the home page of YouTube takes at least 10 minutes. While a video is playing, the device takes longer to switch between tabs and even going back and forth within Explorer is slower than usual. The Celeron N3350 really can't handle anything but the most simple applications.  

The device is equipped with 64 GB of eMMC storage. The storage capacity can be expanded via a storage cart (up to 256 GB) and an M.2 SSD.

Processor

The Intel Celeron N3350 is a dual-core SoC from 2016 (Apollo Lake). It supports dual-channel storage, which is of no use as the 6 GB of RAM are in single channel mode.

You can't do a lot with this processor. On the contrary, the SoC lazes around at the bottom of our R15 loop comparison table, together with the AMD A6-9220e. Performance is constant. You can see clearly why the Pentium N5000 (Medion) and the Celeron N4100 (Chuwi LapBook Pro) are the better choice.

The processor reaches 2.3 GHz in our multi and single-core CineBench tests. The chip does not support hyper threading, which means that it can only work on two threads at the same time. Both the Celeron N4100 and the Pentium N5000 have four cores.

The results of the PCMark 10 benchmark are accordingly low. Only Lenovo's IdeaPad Slim 1 is slower. The results of Medion's Akoya E4253 (Pentium) are the best, and those of the LincPlus P1 (Celeron N4000) aren't bad either. We haven't got any figures for the Chuwi LapBook Pro.

Storage Devices

The 64-GB eMMC is actually rather good compared to other eMMC chips. All our competitor's flash storage devices are even slower. But that's little use considering that the storage speeds are still unbelievably slow compared to real SATA or PCI SSDs.

The system performance might improve if you installed a SATA SSD in the M.2 slot and installed the OS on there, but we can't be sure.

The integrated graphics card Intel HD Graphics 500 should not play a big role in the purchase decision. The most it can do is display browser games smoothly.

Gaming Performance

If you would like to occasionally play real PC games, you're in the wrong price segment. That would require a notebook with a dedicated GeForce MX230 or MX250 at the very least - and those cost $600 minimum.

Pink Noise characteristics

The speakers are weak and not particularly loud. They cannot fill a room. The dual-array microphone records voices very quietly and with a lot of noise. It's almost useless, basically.

Power Consumption

The EZBook is energy efficient and has a particularly low power consumption while idling. This is not surprising considering the low brightness. Still, the Medion Akoya E4253 requires even less power while idling.

Battery Life

The battery life in our Wi-Fi test is reasonable at 472 minutes from a 35-Wh battery. The Medion Akoya E4253 has a slightly higher capacity and still only manages 18% more (555 minutes). For the Wi-Fi test, we reduced the brightness to 150 cd/m² and browsed websites according to a script.

Verdict

Jumper EZbook X3 13.3-inch
Jumper EZbook X3 13.3-inch

The Jumper EZBook X3 is positioned in the lowest possible price segment. It is currently available for $250 - including a Windows licence. Not surprisingly, the processor dates from 2016. At least there's an anti-glare Full-HD IPS display and an M.2 2280 slot for expanding storage capacity.

So what could go wrong? Well... the performance only just scraped by our benchmarks and the stability of the base unit leaves a lot to be desired, which also affects the input devices.  

We cannot recommend buying this cheapie. The competitors from Chuwi, Medion and LincPlus all only cost a little more but are more stable, offer a better performance and better input devices.

This is one of the most wobbly, unstable cases we have ever seen. Do not buy this device.

We can really recommend buying the Medion Akoya E4253, equipped with a Pentium N5000. This 14-inch device also has an anti-glare display and is a lot faster.

Computers interested me early on. With 14 I put together the first PCs for the relatives, with the 90's these were 80286's to 486's up to Pentium 1's. What was closer to becoming a product tester? Since 2007 I have been following the world of Windows laptops and convertibles. Today I also want to separate the wheat from the chaff in vacuum cleaner robots, bread baking machines or irrigation computers, which is why I am also on the road as a freelance editor for other test websites.
