Small, convenient and very rugged Android tablets for logistics, fleet management, field service applications, etc. (provided by Conrad H. Blickenstorfer) Teguar is not necessarily a familiar name when considering the purchase of rugged tablets. This may change because the Charlotte, North Carolina-based company is a hard-to-pay supplier of highly customizable industrial and medical computers and is rapidly rising on the Inc. 5000 list. Teguar was launched in 2010 by a local Swiss with many years of experience in industrial computer systems, combining American adaptability and technological leadership with Swiss precision, quality and attention to detail. In this review, we are studying their rugged and versatile industrial 7-inch Android tablet that fits almost anywhere. Why use a 7-inch tablet for a phone with a screen that is nearly that big? Because mobile phones are not rugged, their screens are long and narrow, and there is no complete accessory ecosystem, they can be integrated into workflows and workplaces that require mobility and complete reliability. On the other hand, Teguar TRT-Q5393-07 is sturdy and durable and can go to work at any time. The image below shows the front and all four sides of the tablet. Why are we showing two different versions of tablets? Because it is not two different versions. It is the same whether there is a protective cap available or not. The cap snaps in within a few seconds and adds significant additional drop protection when needed. They are also easy to fall off, even if the lid is closed, the tablet can still be placed in the optional stand. This is a brilliant solution, very meaningful, and we are surprised that we rarely see it. The two covers can be fixed with several screws, but these are not even necessary; the cap fits like a glove. The size of TRT-Q5393-07 without bumper is 8.3 x 5.2 inches, which is small enough to be installed on various vehicles and can be carried all day long. This tablet is 0.8 inches thick and weighs a little over a pound. What is the use of TRT-Q5393-07? Teguar describes it as a lightweight and portable tablet suitable for industrial and rugged applications, easy to read in the car, outdoors or under bright ceiling lights. Let’s add that providing Android in a small, rugged tablet makes a lot of business sense: According to Google, there are currently more than 3 billion active Android devices worldwide, which means that almost everyone is familiar with the platform. This means getting acquainted immediately and reducing the need for training. Good display In handheld devices and tablets, good display is everything. This applies especially to equipment that will be used under very different conditions, anywhere from the office to the field. Teguar TRT-Q5393-07 has a diagonal screen size of 7.0 inches and a resolution of 1024 x 600 pixels. This results in a 16:10 aspect ratio, somewhere between the iPad’s traditional and fairly square 4:3 display and smartphones that seem to be getting wider every year. 1024 x 600 pixels on a 7-inch screen are 170 pixels per inch. This is less than most smartphones and consumer tablets today. But this is enough for the expected work. Although almost all consumer devices now have "glossy" screens, the anti-glare coating of TRT-Q5393-07 makes it semi-matte. This reduces those annoying reflections that all sleek devices suffer. The image below shows the tablet viewed outdoors from different angles. Like almost all modern mobile devices, TRT-Q5393-07 uses capacitive multi-touch. It is as smooth and responsive as users expect. We are not sure if it uses Corning's Gorilla Glass or something similar (the company claims that the display provides 7H scratch resistance on the Mohs hardness of mineral hardness). Any equipment used outdoors must be bright enough to be used in sunlight, and the battery must not be burned out too quickly to charge. Brightness — Brightness — measured in nits. Laptops usually score around 250 nits, tablets score 300 to 500 nits, modern smartphones score 400 to 550 nits, and some rugged devices can score 1,000 or more. Teguar claims that the tablet is 600 nits. In our brightness test, it performed better than this, with a score of 700 nits, making it easy to view and use outdoors. It is also important that, especially in tablet computers, the display remains visible from any angle and does not change contrast, brightness, or color when viewed from a certain angle. TRT-Q5393-07 passed the test. Excellent build quality Unlike many Windows-based tablets, Android tablets usually do not have access panels for expansion modules, etc. Teguar's TRT-Q5393 is no exception. It's no big deal, because the only reason to open a unit is to replace the integrated internal battery. We have an in-depth understanding of the internal design and layout of the TRT-Q5393. Opening the tablet is easy, as long as there is a Torx T6 screwdriver bit to loosen 16 small screws. Once these are all out, the two black polycarbonate + ABS plastic halves are easily separated, only the speaker and microphone wires and the ribbon cable for docking pogo pins between the two sides. The seal between the two halves is done through a tongue and groove design, which looks like a replaceable black O-ring pressure seal. We didn't see aluminum or magnesium chassis inside. This is because half of the PC + ABS shell is very sturdy, providing a solid structure and foundation for all electronic devices. The figure below shows the TRT-Q5393 opened. Click on the image to get the full-size version. The rechargeable internal 3.7V, 4,000mAH lithium-ion polymer battery provides 14.8 watt-hours, which Teguar says is enough to easily survive long shifts. The battery pack is glued/fixed to the metal frame, but it is fully accessible and replacement should be easy. The internal space of the tablet itself is spacious, and there is no need for excessive miniaturization of electronic products. The battery, motherboard and some modules and antennas are neatly installed in the front of the PC + ABS housing. I/O is limited to the SIM and SDXC card slots with the USB Type-C port facing down and on the right. TRT-Q5393, like almost all ARM/Android devices, adopts a fanless design; it does not even require a metal radiator or dissipator. In general, the internal structure of the Teguar tablet is simple and sturdy. The few visible wires and ribbons are held in place with tape strips. The motherboard itself has a clear label. For rugged equipment, the internal structure determines the reliability and service life, this Teguar tablet can certainly provide. Performance Evaluation The performance and functions of Android devices are completely different from those of Windows/Intel devices. These are easy to determine. After years of review and benchmarking of Intel-based Windows devices, just looking at the spec sheet is usually enough to give us an idea of ​​where the device is in the overall performance environment. Teguar TRT-Q5393 is based on Qualcomm’s Snapdragon 450 mobile platform, running up to 1.8GHz 64-bit octa-core (Cortex A53), including integrated Adreno 506 GPU and camera support and X9 LTE ​​modem. In our benchmark test, Teguar The TRT-Q5393-07 scored 90,735 in the AnTuTu benchmark test suite and 4,917 in the PCMark for Android Work 3.0 test. This is not the level of the most advanced consumer smartphones, and we did not expect it. On the other hand, its PCMark performance is within 20% of Panasonic's high-end Toughbook A3. This is very respectable and absolutely sufficient for the expected market and deployment of this tablet. In terms of communication, TRT-Q5393-07 comes standard with high-speed 4G LTE (certified by Verizon and AT&T operators), dual-band WIFI (802.11 a/b/g/n/ac), Bluetooth 4.2, and GPS/ AGPS and GLONASS positioning. The camera is competent for the job Like almost all modern tablets, Teguar has a front (8 megapixel) and rear (8 megapixel) camera. The included Android camera app does not provide many options and settings, although there are more than the standard Windows camera app. The camera application with more settings and functions can be downloaded from the Google Play store. The purpose of integrating the camera into a tablet computer designed for work should be to alleviate the need to carry a dedicated camera or use a modern smartphone to take pictures. With some practice and depending on the type and quality of the image required, the camera in the Teguar TRT-A5380 can do this. Click the sample image to compile to see its full size. The document camera can also shoot good quality 1080p video. Both cameras are as good or better than the cameras we usually see integrated in rugged tablets. Rugged and durable tablets are designed to bring computing power to the field and work, even if the work is in a harsh environment. This means that the equipment must be able to handle spills, collisions, grinding, and splashes that may occur there. Consumer tablets usually cannot do this, even in some cases. TRT-Q5393-07 is better equipped. Its design and construction are much stronger than any consumer tablet, and it is much less vulnerable. The tablet has a very wide operating temperature range of -4 to 140 degrees Fahrenheit (-20° to +60°C) and can be used and operated in almost any environment, including commercial freezers. In terms of drop resistance, the die can withstand repeated drops of 4 feet without damage. With optional (and highly recommended due to its excellent design and functionality) end caps up to 6 feet are impressive. The entry protection level is IP54. This means that the tablet can prevent the intrusion of harmful dust and can also handle water sprayed from all directions. From the outside and the inside, this tablet actually looks like it can handle IP65 or even IP67. Bottom line: Teguar TRT-Q5393-07 Rugged Tablet Where does Teguar's 7-inch rugged Android tablet fit in? On the one hand, it increases the attractiveness of one-stop shopping for Teguar's main business of providing cutting-edge industrial and medical computer solutions. It is always good to deal with a trusted supplier with whom you already do business. On the other hand, TRT-Q5393-07 has a very wide application potential in many industries due to its ruggedness, very compact size and abundant accessories. Most of Teguar's computers are Windows-based industrial-grade panels and box PCs. However, Android dominates the smartphone market. An almost universal familiarity with Android usually makes it feasible/desirable to use rugged Android-based tablets instead of more complex and expensive Windows-based solutions. The versatile 7-inch TRT-Q5393-07 is perfect for this job. -Conrad H. Blickenstorfer, November 2021
