Blackview, Oukitel, Ulefone or industrial tablet: what the manufacturer data show

Consumer electronics retailers sell rugged tablets from Blackview, Oukitel and Ulefone, and anyone searching for an outdoor tablet comes across them early. This article puts one current tablet from each of the three brands next to three tablets from our range. The values for the third-party devices come solely from the manufacturers’ own pages and were retrieved on 26 and 27 October 2026. Where a page gives no value, the tables say “not stated”. Our values come from the datasheets on robustbook.bitblade.io. We do not sell Blackview, Oukitel, Ulefone or Cat; the current data from the respective manufacturer is always the binding reference. The article quotes no prices.

What Blackview, Oukitel and Ulefone state for their current tablet

For each brand we chose one model whose manufacturer page shows complete technical data: the Blackview Active 12 Pro, the Oukitel RT11 and the Ulefone Armor Pad 5 Ultra. Other models from the same brands have other values, above all for display, weight and battery.

Sources: blackview.hk, oukitel.com and ulefone.com with the specification page, retrieved on 26 and 27 October 2026.

All three manufacturers state IP68, IP69K and MIL-STD-810H. Oukitel and Ulefone give the test condition for IP68: 1.5 m of water depth for 30 minutes, and Ulefone adds that it follows IEC 60529. Blackview writes “IP69” in one headline and “IP68&IP69K” in the specification table; we use the table. On MIL-STD-810H, Blackview writes that the device has passed tests, but the page lists no methods or test values. Oukitel and Ulefone name only the standard. Ulefone also points out that the protection against water and dust is not permanent and may decrease with normal wear; according to this page, the warranty does not cover liquid damage.

The battery figures are not on the same basis. Ulefone gives 24200 mAh and itself converts this to 12100 mAh at 7.74 V, which is about 93.7 Wh. Blackview and Oukitel give no voltage, so their energy cannot be converted to Wh. On updates, Blackview writes: three years of major Android version updates, from Android 15 to Android 17. None of the three pages gives a period for security patches.

Cat: why there is no row in the table

We also wanted to include a Cat tablet. The former manufacturer site catphones.com did not respond when we checked on 27 October 2026: no server is registered for the domain, and www.catphones.com cannot be resolved. We found no other manufacturer page for a current Cat tablet. Without a manufacturer source we write down no values. Anyone who finds a Cat tablet in a shop should ask for the datasheet and the warranty provider before comparing it with another device.

Three tablets from our range

The second table shows three tablets of the same or similar screen size, two with Android and one with Windows. The values come from our datasheets, which in turn rely on manufacturer datasheets from Getac, Fieldbook (Logic Instrument) and Durabook.

From voltage and capacity, the standard battery works out at about 19.4 Wh for the ZX10 G2, 38 Wh for the N101G2 and about 50.2 Wh for the R10. This is a calculation, not a manufacturer figure. The Ulefone tablet is above these at 93.7 Wh, but has no replaceable battery.

Where the data show differences

The protection ratings alone do not separate the two groups. The three retail devices state IP68 and IP69K, our three tablets IP65 and IP66. IP68 tests immersion, IP66 tests powerful water jets, and IP69K, according to Blackview’s description, covers high-pressure and hot water jets; the article IP protection classes explains what the digits mean in detail. By the numbers, the retail devices are at least on a par here. The differences lie elsewhere.

Battery and swapping during operation

The Ulefone tablet has a built-in battery, and the manufacturer warns that removing it may damage the device. For Blackview and Oukitel the page says nothing about replaceability. On the Fieldbook N101G2 the battery can be replaced without tools; for the ZX10 G2 the datasheet names LifeSupport technology for battery swaps, and for the R10 a bridge battery with a one-minute swap time. Anyone who works in shifts and does not want to switch the device off needs this feature; anyone who charges the tablet in the evening does not. More in the article Replaceable batteries and hot-swap.

Temperature and brightness

For operating temperature, the ZX10 G2 and the R10 range from -29 °C to 63 °C, the N101G2 from -20 °C to 60 °C. Blackview states -20 °C to 60 °C, Oukitel -20 °C to 55 °C, Ulefone no range. For brightness, 1000 nits (ZX10 G2, R10) and 700 nits (N101G2) compare with 650 nits for Blackview and 500 nits for Oukitel; Ulefone states no value.

Test data and approvals

All six devices state MIL-STD-810H, and none of the six pages discloses methods and test values. For the Durabook R10, the datasheet also names MIL-STD-461F, the standard for electromagnetic compatibility. On the three retail pages we found nothing on this, nor on ATEX or other approvals for potentially explosive atmospheres. That does not mean they do not exist; it means the manufacturers do not state them there. Anyone who requires them must ask for proof. For standards and drop tests, see MIL-STD-810 for laptops and tablets.

Interfaces, warranty and updates

The retail pages name USB-C (as USB 3.0 for Oukitel, as USB 2.0 for Ulefone; Blackview does not name the USB type), SIM slots and microSD. A docking connector, RJ45 or RS-232 is not listed there. On our side, the ZX10 G2 has a docking connector, the N101G2 has RJ45 and a pogo connector for docking stations, and the R10 has Thunderbolt 4, RJ45 and optionally RS-232. On warranty, the retail pages do not give the duration; Oukitel and Ulefone include a warranty card. Our datasheets name the options “Extended warranty” and “Extended battery warranty” for the R10, but no standard duration; for the ZX10 G2 and the N101G2 the datasheet gives no warranty duration. For the update period the same applies as for the third-party devices: Blackview states three years of Android versions, and our datasheets give no period. Ask about it before you order.

What the datasheets do not decide

A datasheet says what the manufacturer assures, not how long the device will last on your building site, in your cold store or on your forklift. Blackview itself writes that the tests are carried out under laboratory conditions and that results in daily use may differ. This applies to every brand, ours included. Three things can only be settled by checking them before the purchase: whether the application runs on Android or on Windows (see Windows or Android on the rugged tablet), whether the device fits your mobile device management, and whether it needs a dock, a vehicle mount or a serial interface in use.

For use in potentially explosive atmospheres, none of the six tablets compared here states an approval. That needs devices with their own Ex marking; the datasheets of the models named here list none.

When a retail device is enough and when an industrial tablet

A tablet from the retail market can be enough if three conditions come together: it stays mostly in the shade or under a roof, it runs only one shift without a battery swap, and nobody requires approvals, docking stations or an assured availability of the model over several years. That applies to a private outdoor tablet, and to some second devices in a company. The datasheets show solid numbers for water, dust and drops for Blackview, Oukitel and Ulefone.

An industrial tablet becomes necessary when one of these conditions is missing. Mainly that means frost below -20 °C, direct sun at 1000 nits, a battery you swap during operation, a vehicle dock or an interface such as RS-232. The Industrial tablet page classifies these requirements, and the tablet comparison table lists our models side by side. There is a separate article on the iPad on the building site: iPad on the building site or rugged tablet.

Frequently asked questions

Is a Blackview tablet an industrial tablet?

Blackview itself calls the Active 12 Pro a rugged tablet and names construction, agriculture and emergency services as fields of use. We call devices industrial tablets if they have properties such as a replaceable battery, docking, interfaces and documented approvals. Such data is missing on the Blackview page, and it does not say that they must be missing; they are simply not stated.

Which tablet has the bigger battery, Blackview or Ulefone?

According to the manufacturer pages, Blackview with 30000 mAh against 24200 mAh for Ulefone. Ulefone converts 24200 mAh to 12100 mAh at 7.74 V, Blackview gives no voltage. Whether the Blackview figure is meant in the same way is not clear from the page; a comparison in Wh is therefore not possible.

Does Oukitel have a tablet with IP68 and MIL-STD-810H?

Yes, the Oukitel RT11 states IP68 (1.5 m, 30 minutes), IP69K and MIL-STD-810H. The RT11 product page gives no drop height. Other Oukitel models have other values; check the page of the model you want to buy.

Does RobustBook sell Blackview, Oukitel, Ulefone or Cat tablets?

No. We sell Getac, Durabook, Fieldbook, RuggON and Archos. The third-party devices appear here only for comparison.

Conclusion: who should choose which device

Anyone looking for a rugged tablet for a moderate climate, short shifts and no dock will find devices with IP68, IP69K and MIL-STD-810H from Blackview, Oukitel and Ulefone; the pages state 650 nits for Blackview, 500 nits for Oukitel and no value for Ulefone. Anyone who works at -29 °C, needs 1000 nits in the sun, wants to swap the battery during operation or requires RJ45, RS-232 or a dock will be better served by the Getac ZX10 G2, the Fieldbook N101G2 or the Durabook R10. Anyone who needs Windows takes the R10. For Ex zones, none of the six devices states an approval.
