Asus BR1100FKA in review: Affordable and shockproof convertible

Jasper Lake introduces itself. The Asus BR1100FKA costs less than 400 Euros (~$476) and is equipped with simple hardware. However, this is accompanied by a robust and splashproof case as well as by an unexpected expansion option. Our review shows what the Asus convertible has to offer in the end.

Asus BR1100FKA

Besides very expensive convertibles like the ROG Flow X13 and mid-priced devices like the VivoBook Flip 14 TP470EZ, Asus also makes very affordable laptop-tablet hybrids. The Asus BR1100FKA is one such device, which is available in our test configuration with the Intel Celeron N4500Intel UHD Graphics, 64 GB of eMMC flash storage, and 4 GB of RAM for under 400 Euros (~$476).

With this configuration, we put the BR1100FKA up against the competing devices listed below. Other convertibles and laptops from our database can also be added for comparison under each section.

Case and connectivity - Two webcams and optional WWAN

Asus provides the BR1100FKA's case with a surrounding rubber bumper that protects the convertible from impact. Splashing water and shearing motions, for example, are no problem for the device, which is certified according to the MIL-STD-810H standard. However, with a thickness of almost 2 centimeters and a weight of approximately 1.4 kg, the convertible is the thickest and heaviest device in our test field.

The available ports are certainly extensive, but some of them are optional. For example, our test model doesn't have an SD card reader, and the optional WWAN is missing as well. The slot where the stylus can be stored is also blocked by a dummy plug.

Inside the Asus convertible is a free M.2 slot that allows the installation of an SSD. This allows you to expand the very limited eMMC flash memory considerably. Only the corresponding soldering points are visible when it comes to the WWAN module. Neither a slot nor preinstalled antennas are present.

Wireless connections are established by the BR1100FKA-BP0109RA using Bluetooth 5.1 or Wi-Fi 6. Nevertheless, in combination with our Netgear Nighthawk AX12 reference router, only comparatively slow speeds of 216 Mb/s are achieved for sending data and 136 Mb/s for receiving data.

The Asus BR1100FKA is equipped with two webcams, one of which is a 0.9 MP model that is positioned above the display. The image quality is correspondingly low, but it meets the standard of the majority of recent and also much more expensive devices. The second camera is located above the keyboard, resulting in it being at the back of the convertible in tablet mode. With a resolution of 12 MP, much better pictures can be taken with it.

Input devices - Stylus not included

The keys of the Asus BR1100FKA offer a clearly perceptible feedback and are well suited for typing longer text. The arrow keys are a bit smaller and, therefore, less intuitive to use. Keyboard backlighting is not available.

A ClickPad is used as mouse replacement, allowing the mouse pointer to be controlled well. It also responds well to touch inputs and mechanically triggered clicks. If the device is operated using the touchscreen, taps are picked up responsively. However, the surface is not very well suited for drag-and-drop motions. The input stylus shown in the picture is optionally available for purchase.

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
25 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 11 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. » 45 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (23.9 ms).
       Response Time 50% Grey to 80% Grey
34 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 19 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. » 30 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (37.8 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 2500 Hz

The display backlight flickers at 2500 Hz (Likely utilizing PWM) .

The frequency of 2500 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 15366 (minimum: 5 - maximum: 2500000) Hz was measured.

Color-space coverage (sRGB) - 68%
Color-space coverage (sRGB) - 68%
Color-space coverage (AdobeRGB) - 43%
Color-space coverage (AdobeRGB) - 43%

According to our measurements, the Asus BR1100FKA offers a comparatively high contrast ratio of 1,241:1 and a low black level of 0.195 cd/m². Although the color-space coverage of 68% corresponds to the average of this class, the value provided is still quite low. The CalMAN analysis also shows that colors are displayed only with a slight deviation out of the box.

When the convertible is used outdoors, strong reflections and glare obstruct the view of the display. However, the built-in panel is very viewing-angle stable, which allows content to be displayed without distortions or inaccurate colors even from flat angles.

Performance - Asus BR1100FKA suitable for typing tasks

Asus is targeting the BR1100FKA at users who are looking for a robust convertible for applications that don't require a lot of system performance. Typing tasks and Internet browsing are possible without any problems. Our test unit comes with the base configuration. For an additional price, the device is also available with the somewhat stronger Intel Celeron N5100 or the Intel Pentium Silver N6000.

The storage configuration is variable as well, and you can opt for up to 16 GB of RAM and 128 GB of eMMC flash storage. The RAM and flash memory can't be upgraded, though, since they're soldered in place.

Processor

The Intel Celeron N4500 used here is a processor with two cores from Intel's Jasper-Lake generation. It doesn't support multithreading, it can only process two tasks at the same time as a result. Its predecessor is the Intel Celeron N4020 CPU, which is installed in the Lenovo IdeaPad Flex 3 in our test field.

As our Cinebench R15 test shows, the N4500 achieves an almost 20% higher score than the N4020 right at the beginning of the endurance test. However, the Asus convertible's result drops very sharply subsequently, and it only delivers rates below the IdeaPad Flex 3 up until the end of the test. Both devices are passively cooled.

When it comes to the individual disciplines, the Asus BR1100FKA performs within the range of our test field, but it's outperformed by devices with quad-core CPUs in multi-core applications in particular.

System performance

In the PCMark 10 test for evaluating system performance, the convertible from Asus only reaches the lower place in our test field. This is true both for the overall score as well as the individual results. Nevertheless, the BR1100FKA can be operated smoothly in everyday use, and it responds reliably to inputs. You can expect short waiting times when launching applications.

Our CPU Benchmarks article shows the performance offered by other devices in comparison.

Storage

Asus uses a 64 GB eMMC flash storage device in our test configuration. Although it's a bit faster than other devices with this storage type, it's still significantly slower than affordable SSDs like those used in comparable competing devices. The 64 GB are largely occupied by the operating system, which is why investing in a model with 128 GB of storage is recommended.

Our HDD/SSD Benchmarks article shows the speeds offered by other mass storage devices in comparison.

Graphics card

The Intel UHD Graphics (Jasper Lake 16 EUs) internal graphics unit takes care of displaying image content. It's only suitable for applications with low graphics performance requirements, meaning that simple image-editing tasks, for example, can only be executed with longer waiting times. The Asus BR1100FKA achieves better scores than our test field in the 3DMark benchmarks, but it's still at a low level overall.

Our GPU Benchmarks article shows the performance that can be expected from other graphics cards.

Gaming performance

The Asus BR1100FKA convertible isn't designed for gaming. Even older titles can't be run smoothly at the lowest graphics settings. As a result, only games like solitaire can be executed without problems.

In review: Asus BR1100FKA. Test device provided by: Asus Germany

The Asus BR1100FKA proves to be a convertible for simple tasks in the test. The installed hardware is perfectly sufficient for office applications and Internet browsing, but you shouldn't expect anything else beyond that. Wi-Fi is comparatively slow, and the display is only suitable for working indoors. In return, battery life is comparatively long.

The Asus BR1100FKA is well suited for applications that require little performance but a robust device at the same time.

The biggest plus point, however, is the robust case that protects the interior from bumps and splashing water. While the built-in storage in the 64 GB version is very limited, it can be expanded significantly via the free SSD slot. If money isn't the main factor, you should also consider the version with 128 GB of internal storage as well as more RAM. But if the robust case is not needed, the Lenovo IdeaPad Flex 3, for example, is the better choice.

Price and availability

You can find the 128 GB version of the Asus BR1100FKA in newegg for around $415. Alternatively, you can also find this model on Amazon for a bit less at around $400.

I carried out my first IT experiments with a 386-based system and a whole 4 MB RAM. This was followed by work on various PCs and laptops that I maintained and repaired for friends and acquaintances. After training to become a Telecommunications Systems Technician and gaining a few years of experience, I graduated with a Bachelor’s degree in Industrial Engineering. Currently, I pursue my fascination for IT, technology, and mobile devices by writing reviews and articles for Notebookcheck. I have also worked for Gamestar, Netzwelt, and Golem, among others.

I've been fascinated with technology ever since I got my very first Android smartphone, which was quite a while ago. The power packed into such a small footprint still amazes me. Learning to program made my understanding of technology deeper, and at the same time, it expanded my interest to the area of desktop computers and laptops. All this led me to enjoy reading and watching reviews of new devices, and that's how I stumbled upon Notebookcheck. I immediately found their reviews to be very comprehensive, and luckily, I've even had the chance of translating them since 2019. When it comes to the huge field of technology, I'm currently also interested in specializing in Java programming.
