Chuwi LapBook Air 14.1 (N3450, FHD) Laptop Review

Attractive and slow. Chuwi's MacBook Air clone certainly looks nice and could easily pass as an Ultrabook twice the price. Dig a little deeper, however, and the small flaws quickly begin to crack.

Chuwi only recently dived into the world of laptops after having released a string of affordable Android and Windows tablets. In keeping with its tradition of a budget-oriented product line, the new LapBook series of super-thin notebooks is home to very affordable products inspired by the designs of costlier flagship Ultrabooks. The MacBook Air, for example, was an obvious source of inspiration for the LapBook 12.3 and LapBook Air 14.1.

The LapBook 14.1 is currently available in two SKUs. The less expensive SKU with 4 GB of RAM, 64 GB eMMC, matte display, and plastic chassis retails for around $250 USD while the pricier LapBook Air 14.1 SKU doubles the RAM and storage with a glossy display and magnesium alloy chassis for around $400 USD. Either way, both configurations are equipped with the same quad-core Celeron N3450 CPU, integrated HD Graphics 500 GPU, FHD resolution panel, and connectivity features. Our test unit today is the latter configuration which is still quite the steal considering the very low asking price. Though attractive from the outside, we'll be scrutinizing the hardware to see what devils Chuwi may be hiding under the details.

Direct competitors include the HP Pavilion 14, Lenovo IdeaPad 320s, and Acer Aspire E5.

Case

Small imperfection on edge of notebook
Small imperfection on edge of notebook

If visual appeal was Chuwi's goal with the LapBook Air, then they have hit a home run. There's no denying that the gray Magnesium alloy design looks classier than the usual plastic notebooks in this price category. The chrome-cut edges shimmer under ambient lighting and the smooth matte surfaces are excellent at hiding fingerprints and grease. In comparison, the 14-inch Razer Blade utilizes an all-black black Magnesium alloy chassis that accentuates fingerprints from every angle. This is a flagship facade for a budget price.

Chassis quality is where the LapBook Air begins to show signs of cut corners. Simply adjusting the angle of the lid will cause audible creaking around the plastic hinge and our test unit has a slightly bent edge near the USB port as shown by our image to the right. Attempting to twist the lid and the chassis base will result in slight creaking as well. Otherwise, rigidity is actually very good for both the lid and base largely due to the glass screen reinforcement and CNC alloy material. Commonly weak areas of notebooks like the center of the keyboard or outer lid show minimal flexing when applying pressure.

In terms of size and weight, the portable LapBook is slightly lighter than competing budget alternatives including the Pavilion 14 and IdeaPad 320s. It's also about as light as the 13.3-inch MacBook Air while offering a larger 14-inch screen size. The chrome edges and corners around the base and lid make the LapBook appear thinner than it actually is when in reality the notebook is slightly thicker than the aforementioned HP and Lenovo alternatives.

Connectivity

Availabe ports are easy to reach on the left- and right-hand edges of the notebook. Perhaps annoyingly, there are no USB ports on the left side and most users will be needing a mini-HDMI to HDMI adapter to utilize the mini-HDMI port similar to the Jumper EZBook 3. The thicker HP Pavilion 14 incorporates more USB ports, a full-size HDMI port, a full-size SD reader, and a Gigabit Ethernet port for better connectivity.

We experienced a power delivery issue on one of two USB 3.0 ports on our test unit. Connecting an external storage drive would only work on one of the two ports as the other would constantly toggle our external storage drive on and off even after multiple tries.

SD Card Reader

Good luck ejecting the MicroSD card
Good luck ejecting the MicroSD card

Chuwi could have easily omitted a card reader altogether but has included a spring-loaded MicroSD slot for storage expansion. Transfer rates with our Toshiba THN-M401S0640E2 MicroSD card are slow at about 45 MB/s compared to almost twice that on the Samsung Notebook 9 when using the same MicroSD card. Transferring 1 GB worth of photos from the card to desktop takes about 27 seconds compared to under 9 seconds on the Dell XPS 13.

A fully inserted MicroSD card sits flush against the edge of the notebook as shown by the image to the right. While good for transporting, users with short nails and larger fingers will have a very tough time removing the card.

WLAN is provided by an Intel 3165 M.2 1216 module for 802.11ac and Bluetooth 4.2 connectivity. Real-world transfer rates when standing next to our Linksys EA8500 test router average just over 300 MB/s as expected from a 1x1 WLAN card. We experienced no reliability issues during our time with the test unit.

Accessories

There are no included extras outside of the Warranty card and Quick Start guide.

Maintenance

The bottom panel requires only a Philips screwdriver to loosen the 12 screws. Though servicing is easy, upgradeability is limited to the secondary M.2 2242 SSD.

Warranty

The standard one-year limited warranty applies. Buyers are responsible for paying return shipping costs.

Input Devices

Keyboard

The keyboard looks great at first glance. Its keys are large and travel appears deep because of how elevated the keys are from the base. In practice, however, feedback is soft and nowhere near as firm as on the Lenovo AccuType keyboard. The Enter and Space keys in particular feel spongier than on most other major Ultrabooks including on the XPS 13. The corner Ctrl key on our unit also malfunctioned during testing and lacks feedback completely. Users who intend to do lots of typing on the LapBook Air will need some time to become accustomed to the keyboard.

A one-level backlight is included for working in dimly lit conditions. While its luminosity is uneven across the keyboard as shown by our image below, the fact that a backlight is available at all in this price range should be appreciated.

Touchpad

The wide clickpad (11.0 x 6.5 cm) is large for the screen size and its surface is smooth to the touch. Unfortunately, the finger tends to stick when gliding very slowly and so smaller precision cursor movements are more difficult. Slight cursor jitters become apparent during slow movements as well. Multi-touch gestures of up to four fingers are otherwise responsive and reliable.

The integrated mouse keys are shallow and very spongy. Inputting a click demands a great deal of force from the user compared to the clickpads on other notebooks. As a result, the simple action of pressing down on the clickpad can be tiring especially if clicking in rapid succession.

Display

The LapBook Air comes standard with a glossy 1080p IPS display and no touchscreen options. The BOE06A8 panel can be found on no other notebook in our database. Its backlight is bright enough for indoor environments but is merely average for its size class at 243 nits. The display on the Samsung Notebook 9, for example, is nearly twice as bright at 481 nits. Contrast and display response times are good considering the price but average compared to flagship Ultrabooks.

Subjectively, onscreen text is sharp and colors pop due to the thin edge-to-edge glass overlay. Unfortunately, the panel suffers from PWM when the brightness level is set to 20 percent or lower. Our specific unit also suffers from moderate-heavy backlight bleeding around the edges and corners that is common amongst budget notebooks.

Color space is approximately 40 percent and 63 percent of the AdobeRGB and sRGB standards, respectively. This is very common amongst older or lower-end panels like on the HP Pavilion 14. Flagship Ultrabooks like the Zenbook 3 or Yoga 920 cover much more of sRGB for deeper and potentially more accurate colors.

Further measurements with an X-Rite spectrophotometer reveal inaccurate colors and grayscale out of the box. Our calibration efforts improve grayscale by lowering the color temperature, but colors are still generally inaccurate especially at higher saturation levels where the limited color space takes its toll. Pure Red, for example, appears Red-orange and Blue appears more Blue-violet. Blue and Magenta colors in particular are not reproduced as accurately as the other colors.

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
29.2 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 13.2 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. » 69 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
32.8 ms ... rise ↗ and fall ↘ combined↗ 12.8 ms rise

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 20 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41 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 200 Hz ≤ 20 % brightness setting

The display backlight flickers at 200 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9265 (minimum: 43 - maximum: 142900) Hz was measured.

Outdoor visibility is average at best when under shade, but the screen is far too dim when under sunlight or a clear sky. The backlight is not powerful enough to overcome glare from the glossy screen and so users will be constantly adjusting the display to minimize glare. Luckily, the IPS panel allows for very wide viewing angles with only slight blue-violet tints if viewing from extreme angles.

Performance

No other CPU, GPU, or display options are available for the LapBook Air 14.1. The 6 W Apollo Lake Celeron N3450 is uncommon but can be found on very inexpensive notebooks including on the Acer Spin 1 and Chuwi's own LapBook 12.3. RAM is soldered and fixed at 8 GB DDR3L.

 

Processor

Raw CPU performance is very similar to that of the Atom x5-Z8550. This is bottom-of-the-barrel as even a lowly Core i3-6100U is over twice as fast according to CineBench benchmarks. Even the AMD A9-9420, which we blasted for its slow processor performance, runs objectively faster than our Celeron N3450.

The CPU is otherwise steady when under stress. Running CineBench R15 Multi-Thread in a loop results in uniform scores over time.

System Performance

PCMark benchmarks rank the Chuwi far below more common and pricier alternatives like the MacBook Air 13. Subjectively, installations and launching applications take much longer to complete and are nowhere near as instantaneous as Core ix-based Ultrabooks.

We experienced at least two crashes when attempting to restart the system and when waking up from Sleep. Our unit also had problems installing the latest Windows 10 updates and required multiple tries.

Storage Devices

A soldered primary 128 GB SSD is included with an unoccupied M.2 2242 slot for expansion. This is a unique feature of the Chuwi notebook as most budget offerings and even major flagship ones do not offer secondary storage options.

Unfortunately, the primary drive is very slow by SSD standards. The SanDisk DF4128 in use is very similar to the SanDisk SSD in the Lenovo Ideapad 110S and both share nearly identical CrystalDiskMark scores. Sequential read rate is only 183 MB/s compared to 500+ MB/s on most newer SATA III SSDs. Even the SATA II SSD in the old Vizio laptop clocks in faster than this particular SanDisk SSD.

See our table of SSDs and HDDs for more benchmark comparisons. Both AS SSD and PCMark 8 Storage do not run successfully on our unit possibly due to to issues installing Microsoft's Net Framework.

GPU Performance

The integrated HD Graphics 500 is incapable of gaming and offers no appreciable performance benefits over the HD Graphics 400. 4K UHD playback, however, is now possible. Both 1080p60 and 2160p60 videos from YouTube play smoothly with no major dropped frames. Note that CPU utilization can be as high as 90 percent during 2160p playback with an average in the 50 to 70 percent range. As such, heavy multi-tasking during 4K UHD playback may not be the best idea.

See our dedicated GPU page on the HD Graphics 500 for more technical information and benchmark comparisons.

Stress Test

We stress the notebook with unrealistic processing loads to identify for any potential throttling or hardware issues. When under Prime95 stress, the CPU can be observed stabilizing in the 1.5 to 1.6 GHz range compared to its base clock rate of 1.1 GHz. Clock rate drops to 1.2 GHz whilst running Prime95 and FurMark simultaneously, which is impressively still above the base clock rate. Core temperature never climbs above 71 C.

Running on battery power will not impact CPU or GPU performance. A 3DMark 11 run on batteries returns Physics and Graphics scores of 1772 and 419 points, respectively, compared to 1823 and 390 points when on mains.

Emissions

System Noise

The cooling solution consists of a copper heat spreader in place of a fan and heat pipe. While fan noise is absent, we can identify very slight coil whine emanating from the left side of the notebook when under high processing load. The noise is generally inaudible when sitting at a normal distance away from the notebook and shouldn't be a distraction as a result.

Temperature

Hot spots are very localized as is common on passively-cooled notebooks. In this case, the left half of the notebook will always be noticeably warmer than the right because of the positioning of the motherboard. The left palm rest and WASD keys can be about 3 C to 4 C warmer than the right side even when idling on desktop. If not working on a flat table, the temperature variation may be of slight annoyance to users. Most other ultra-thin notebooks like the Spectre 13 have more symmetrical surface temperature development to reduce temperature disparities and improve user comfort.

The integrated stereo speakers are unimpressive with tinny sound and poor bass reproduction not unlike on an inexpensive tablet. As our pink measurements below show, maximum volume could be louder and with better balance between bass and treble frequencies. The palm rests reverberate slightly at higher volume settings but there is otherwise no distracting static. While we don't expect great sound quality from a budget Ultrabook, the low maximum volume is just barely enough to fill a medium-sized conference room.

Power Consumption

With limited power comes limited power consumption. The Chuwi will draw anywhere from 3 W to 7 W when idling on desktop depending on the Power Profile and backlight brightness compared to 5 W to 9 W on the 14-inch HP Pavilion 14 powered by the more powerful i7-7200U CPU. The power savings on the Chuwi become more impressive when under higher loads as the system never draws more than 15 W.

The small (9.5 x 4.5 x 3.0 cm) 36 W AC adapter is more than enough for powering the LapBook 14.1.

Battery Life

The internal 38 Wh battery is average for its size class and runtimes are subsequently mediocre. Real-world WLAN loads will last for just over 6 hours while the IdeaPad 320S can last for almost 8 hours when subjected to the same conditions. Perhaps more disappointingly, runtimes are not any better than notebooks with faster U-class Core ix processors.

Charging from near empty to full capacity will take 3.5 hours. This is very slow considering the small size of the battery and that most other notebooks normally take around 2 to 2.5 hours to fully charge.

Verdict

In review: Chuwi LapBook Air 14.1. Test model provided by Chuwi

The LapBook Air looks and feels amazing considering the low $400 asking price. The 1080p IPS display is sharp, the secondary internal storage option is rare, and there is even a keyboard backlight. Unfortunately, the manufacturer had to make some deep cuts almost everywhere else to hit the impossibly low MSRP.

For starters, quality assurance isn't up to par with more well-known alternatives. Our test unit suffers from moderate display backlight bleeding, uneven keyboard backlight lighting, a broken Ctrl key, a faulty USB port, multiple crashes, and a bent edge. We highly recommend that new owners test out every port and key to ensure that there is nothing physically damaged. Secondly, the passively-cooled Celeron processor, primary SSD, and AC charger are all very slow. Users who want something a little more powerful would be better off with an older ULV Haswell notebook that will likely have firmer keyboard keys and more precise trackpads. If primarily used for streaming and video playback when on-the-go, however, the LapBook Air is not bad.

The LapBook should prove useful for those who only plan on web browsing, word processing, and streaming video content.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
