The Oukitel RT3 Plus is the most capable compact rugged tablet in our range — combining IP68 and IP69K dual waterproof certification, Android 15, an 11000mAh battery, NFC and 4G Dual SIM connectivity in an 8-inch form factor that weighs just 625g. For field professionals who need genuine rugged protection in the most portable package available, the RT3 Plus delivers everything that matters without the weight and bulk of larger 10-inch devices.

At 206.9×134mm it fits comfortably in one hand, in a jacket pocket and in a vehicle door pocket — available wherever you need it, light enough that carrying it all day requires no effort. Android 15 ensures long-term software support and full Google Play compatibility from day one.

IP68 and IP69K — Dual Waterproof Certification on a Compact Tablet

The RT3 Plus carries both IP68 and IP69K waterproof certification — a combination that covers every water-related risk in field and industrial environments, and one that is particularly impressive on an 8-inch compact tablet.

IP68 certifies full waterproofing against sustained submersion — protecting against rain, puddles, wet working surfaces and accidental drops into water. IP69K goes further, certifying protection against high-pressure, high-temperature water jets directed at close range from any angle. This is the standard required for equipment used in food production, agricultural environments, industrial cleaning operations and vehicle washing facilities where pressure hoses are used as part of normal daily operations.

The combination of both ratings in a 625g compact form factor makes the RT3 Plus one of the most portable IP69K certified tablets available in the UK.

Android 15 — Latest OS on a Compact Rugged Tablet

The RT3 Plus ships with Android 15 — the most current version of Android available — ensuring long-term software support, the latest security updates and compatibility with current and future field management applications. For businesses deploying tablets across field teams and expecting several years of operational use, starting on Android 15 maximises the effective lifespan before end-of-support becomes a concern.

Full Google Play Store access means every field management, logistics, warehouse and operational application used across UK industries is available without sideloading or compatibility workarounds.

11000mAh Battery — Multiple Days of Field Use in a Compact Package

The 11000mAh battery is exceptional for an 8-inch compact tablet — delivering multiple full working days on a single charge under normal field conditions. For shift workers, outdoor professionals and field operatives who cannot afford tablet downtime mid-shift, this battery capacity means the RT3 Plus outlasts the working day comfortably regardless of usage intensity.

The 18W Type-C fast charging minimises downtime when topping up, and reverse charging support means the RT3 Plus can charge other devices — phones, earbuds or accessories — from its own battery reserve when power points are unavailable in the field.

MediaTek Helio G81 — Smooth Performance for Field Applications

The MediaTek Helio G81 Octa-Core processor runs two Cortex-A75 performance cores at 2.0GHz alongside six Cortex-A55 efficiency cores at 1.7GHz — delivering smooth, responsive performance for everyday field computing, data entry, communications, navigation and application use. Combined with 4GB of LPDDR4X RAM and 12GB of virtual RAM expansion and 128GB of eMMC storage, the RT3 Plus handles multitasking and field application demands without slowdown.

Storage is expandable via microSD up to 1TB — giving field teams substantial capacity for offline maps, documentation, photography and operational data without relying on cloud connectivity.

8-Inch Display — Practical Portable Working Space

The 8-inch IPS display runs at 800×1280 resolution with 188PPI pixel density, 420 nits of brightness and an 87.8% screen-to-body ratio — giving you a clean, clear display that maximises working space within the compact chassis. The 420 nit brightness ensures readability in outdoor and bright industrial environments where lower brightness displays wash out. The 60Hz refresh rate keeps navigation and scrolling smooth throughout the working day.

At 206.9×134mm the display gives you practical working space for field management software, logistics applications, documentation review, navigation and video calls — in a form factor that a 10-inch tablet simply cannot match for one-handed portability.

NFC and Quad-Satellite Navigation

The built-in NFC module supports the full range of Android NFC applications — access control, asset and inventory tag scanning, contactless data transfer and smart label workflows used across warehouse, logistics, healthcare and facilities management operations. For field professionals who need NFC capability alongside rugged protection in a compact device, the RT3 Plus covers both without compromise.

Quad-satellite navigation supporting GPS, GLONASS, BeiDou and Galileo simultaneously delivers fast, accurate positioning for field operations, delivery routing, site location and logistics coordination — across urban, rural and remote environments where single-system GPS loses reliability.

4G Dual SIM for Maximum Connectivity Flexibility

The RT3 Plus supports two Nano SIM cards simultaneously — enabling separate business and personal SIMs, dual-network coverage for maximum field connectivity, or network switching in areas where one provider has weak signal. Comprehensive 4G LTE band support covers all major UK networks across FDD and TDD bands. Dual-band WiFi covering 2.4GHz and 5GHz provides reliable wireless connectivity when on-site networks are available. OTG support enables direct connection of USB peripherals and accessories.

16MP Camera for Field Documentation

The 16MP rear camera uses an OV16880 sensor with F2.0 aperture and autofocus — producing sharp, detailed images suitable for professional field documentation, inspection photography, site condition records, asset management and delivery confirmation. The depth-sensing sub-camera adds dimension data for photography applications requiring spatial awareness. The 8MP front camera using an IMX219 sensor handles video calls and remote briefings clearly, with 1080P 30fps video recording on both cameras.
