Oukitel RT2 review - Extremely robust outdoor tablet for the construction site with monster battery and LTE
The outdoor tablet from Oukitel is equipped with a 10.1-inch FHD+ display and relies on a MediaTek chipset with 8 GB DDR4X RAM. Besides the high resistance against damaging environmental influences, the Oukitel RT2 has another equipment highlight - the capacity of the installed battery is very generous at 20,000 mAh. The RT2 can even function as a power bank for the smartphone or smartwatch.

Case - Oukitel tablet with IP rating
The focus of the Oukitel RT2 is on high stability and durability. The outdoor tablet gets the former from a solid metal frame that contributes to the hefty weight of over 1000 grams (~2.2 lb). The display-to-surface ratio, on the other hand, is rather modest at only 71 percent.
The build quality is on a satisfactory level. The casing, which is mainly made of plastic, can convince with a high certification according to IP-68/69K and the MIL-STD-810H standard. The IP69K certification even protects the Oukitel RT2 from hot water during high-pressure cleaning from a short distance.
Features - mid-range tab with FM radio
The Oukitel RT2 is only shipped with one storage size, namely 128 GB. After deducting the operating system, approximately 109 GB are still available. Users who need more capacity can expand the storage by up to 1 TB via microSD cards without exFAT support. Alternatively, the second card slot enables another SIM card for dual use.
Besides an FM radio and a status LED, the outdoor tablet supports wireless transmission via Miracast and USB OTG. Data can then be read out through the USB Type-C port, for example for playing video material, and to connect other external peripherals, such as external keyboards. According to Oukitel, the USB port is supposed to deliver a data transfer rate of up to 500 MBit/s. We assume that the 2.0 standard is meant here.
microSD card reader
The integrated microSD slot supports the current SDHC and SDXC standards. The outdoor tablet's performance in the Cross Platform Disk test is quite convincing in combination with our reference card Angelbird AV PRO V60. However, the outdoor tablet is quite slow with a copy speed of less than 15 MB/s.

Software - Oukitel RT2 with Android 12
The Oukitel tablet is based on Android in version 12, which the Chinese manufacturer combines with its in-house user interface. At the time of the test, the security updates are from September 2022 and the Widevine DRM level is L3. Oukitel does not specify whether and how many major Android updates will follow.
Communication and GNSS - Oukitel tablet with LTE
Bluetooth version 4.2 is available for wireless communication - an NFC chip is not installed. The integrated Wi-Fi module supports the IEEE 802.11 standard according to a/b/g/n/ac and thus theoretically operates in the 2.4 GHz and 5 GHz frequency ranges. However, we could only test the Oukitel RT2 in the slow 2.4 GHz band since 5 GHz WLAN was not supported with our reference router, the Asus ROG Rapture GT-AXE11000. The transmission speed is thus very slow and also proves to be somewhat unstable in use - the WLAN module often lost the connection to the router during the test.
However, the outdoor tablet can also access the mobile Internet with a maximum of LTE Cat. 7 thanks to a 4G modem. All popular bands in this country, including bands 20 and 28, are supported.

Oukitel RT2 |
The Oukitel RT2 uses the GPS, BeiDou, Galileo and GLONASS satellite networks for positioning, but only in single-band. The outdoor positioning can score with a good accuracy, but the positioning takes quite a long time and is below average with an SNR value of under 30.
In addition, we check the positioning accuracy on a bicycle tour and compare the results with Garmin's Venu 2 smartwatch. Since the GNSS test was always aborted with our test device, we cannot provide a detailed route course for the Oukitel RT2.
Cameras - Oukitel RT2 with single cam
A 16-megapixel front-facing camera with an f/2.4 aperture is located in the display's upper frame. As tablets go, the quality of the photos is more than sufficient for video calls and quick selfies. Oukitel overdoes it in terms of color contrasts and exposure, but the front-facing camera still takes solid pictures.
The rear also features a 16-megapixel camera with an aperture of f/2.2. The image sharpness and details of the pictures are usable in bright light, but the quality is modest even for a tablet in this price range. Dynamics and sharpness are in need of improvement and the exposure is not a strength of the outdoor tablet.
However, we are somewhat surprised by the color reproduction - and in a positive way. In order to be able to evaluate the color reproduction under the most objective conditions possible, we take additional photos with the Oukitel RT2 in artificial light with the help of the X-Rite ColorChecker Passport. The photos surprised us with a relatively true color reproduction.

Accessories and warranty - Oukitel tablet with power adapter
The Chinese manufacturer equips its outdoor tablet with a 33-watt power supply, a USB cable and a wrist strap including mounting utensils.
The Warranty is 12 months.
Input devices & operation - Oukitel RT2 with FaceUnlock
The outdoor tablet has a capacitive touchscreen with convincing gliding properties. There is also nothing to complain about in terms of precision, so our inputs with the fingers are accurately implemented. However, the touchscreen response is often a bit delayed or only works on the second try.
A 2D face recognition is available for biometric security. The recognition is quite fast, but a fingerprint sensor is unfortunately not available.
Display - Oukitel tablet with IPS panel
The 10.1-inch IPS display has a 2K resolution and a pixel density of just over 200 ppi. The IPS panel with 60 Hz has a somewhat uneven illumination, but we cannot see any significant shadowing.
Interestingly, Oukitel advertises its outdoor tablet with a peak brightness of 350 nits. However, the maximum brightness of 488 cd/m² measured by us with a pure white screen background is clearly higher. In addition, we check the panel's luminosity with a certain proportion of dark to bright areas (APL18) in the test. Here, we determined a similar maximum brightness of 445 cd/m².
It should be noted that despite LC technology, flickering with a very high frequency of about 300k Hz can be determined by us. In our temporal dithering test, the outdoor tablet exhibits conspicuous flickering of the subpixels.

Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 316400 Hz | ||
The display backlight flickers at 316400 Hz (worst case, e.g., utilizing PWM) . The frequency of 316400 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8619 (minimum: 5 - maximum: 343500) Hz was measured. |
The analysis of the photospectrometer and the CalMAN software reveals strongly increased Delta-E deviations from the sRGB color space with 10.1 (colors) and 10.6 (grayscale) in the factory preset color profile "Natural". We also noticed a clear blue cast in the grayscale. The black value to maximum brightness ratio of about 1:750 is also below average for an IPS panel.

Performance - Oukitel tablet with MediaTek SoC
The Oukitel RT2 is based on the MediaTek MT8788, an octa-core SoC manufactured in a 12 nm process. Four Cortex-A73 cores face a Cortex-A53 cluster for power-saving tasks. The graphics unit is a Mali-G72 MP3.
In combination with the 8 GB RAM, the MediaTek chipset, which is almost identical to the Helio P60T, ensures a solid system performance. However, the outdoor tablet reveals a few hangs, and animations often do not look smooth.
In our benchmark package, the rather weak CPU unit offers low results in Geekbench, especially in single-core. In multi-core, the chipset installed in Oukitel's RT2 performs on the level of a Helio G80.

However, the Oukitel RT2 does not perform much better in the graphics tests. The Mali G72 MP3 in the outdoor tablet is often even beaten by a Mali G52 MP2 of the Teclast T40 Pro in the graphics tests of GFXBench. But even in the Wild Life benchmarks of 3DMark, the results are only marginally different from a Lenovo Tab M10 Plus Gen 3.

Games - Oukitel tablet manages 60 fps
Using the GameBench app, we take a look at the Mali-G72 in more detail using games from the Play Store. Here, the GPU manages a maximum frame rate close to the panel's native 60 Hz mark - at least temporarily. However, these are only reached in less graphics demanding games, such as Armajet, due to the underpowered graphics unit.
Graphically demanding games, such as PUBG Mobile in HD, can be played smoothly on the outdoor tablet, but it stops at 30 fps. It is not possible to play the shooter in the best display quality, UltraHD. The racing game Asphalt 9 Legends also reached 30 fps in the test, but massive frame rate drops are partly noticeable.
Emissions - outdoor tablet stays cool
Temperature
The surface temperatures of the outdoor tablet are hardly noticeable even under load. Thus, the Oukitel RT2 unsurprisingly reveals a very continuous performance in the 3DMark Wild Life stress tests.
3DMark Wild Life Stress Test
(+) The maximum temperature on the upper side is 35 °C / 95 F, compared to the average of 33.7 °C / 93 F, ranging from 20.7 to 53.2 °C for the class Tablet.
(+) The bottom heats up to a maximum of 32.6 °C / 91 F, compared to the average of 33.2 °C / 92 F
(+) In idle usage, the average temperature for the upper side is 29 °C / 84 F, compared to the device average of 29.9 °C / 86 F.
Speaker
The tablet from Oukitel has two speakers that offer stereo sound, but cannot really keep up with the rich sound of the tablet competition in the mid-range price segment. Especially lower frequency ranges are hardly present in the RT2's sound. The high tones also clearly collapse.
Wired headphones can be connected to the outdoor tablet via the USB Type-C port. Alternatively, Bluetooth 4.2 can be used for wireless transmission. A rather limited codec palette of SBC, AAC, aptX, aptX HD and LDAC is available here.

Battery life
The outdoor tablet lasted over 21 hours in our practical Wi-Fi test with an adjusted display brightness of 150 cd/m². This is an excellent rate, but we would have expected a bit more stamina in relation to the extremely large battery.

Pros
Cons
Verdict
Given the very high weight for a 10.1-inch tablet, the Oukitel RT2 will probably only appeal to a group of people who absolutely need a high degree of durability. However, due to the IP-68/69K and MIL-STD-810G certifications as well as the massive construction, the outdoor tablet occupies a niche, which could make it an interesting choice for construction site use, among others, despite the existing weaknesses. Those who can do without a shock- and waterproof case will be better off with a Xiaomi Pad 5 or Huawei MatePad 11.
The slow and unstable WLAN coupled with the lame SoC limit the Oukitel RT2's recommendability.
In relation to the price of the Oukitel RT2, we find the chipset to be too weak, despite the high protection level. The relatively low brightness of the IPS panel and the deficits in tracking (dropped connections, single-band use) do not really fit into the concept of an outdoor tablet.
Price and availability
The Oukitel RT2 is available for about 330 Euros (~$327) as an import and for 400 Euros (~$396) on eBay. So far in Germany, only the predecessor is listed at Amazon.de.
