Product information

Description

The Ulefone RugKing 4 Pro is a rugged Android 15 smartphone with a 6.56" (16.7 cm) display, reinforced with Corning Gorilla Glass 3 and rated IP68/IP69K for dust and water protection. Built to meet MIL‑STD‑810H standards, it combines a durable chassis with long battery life from a 10,200 mAh battery and moderate performance from an octa‑core Unisoc T7250 processor paired with 8 GB RAM and 128 GB internal storage (expandable via MicroSD).

Advantages

The device offers extreme durability for outdoor and industrial use, including drop and water resistance, plus a large-capacity battery for extended runtime. Its 48 MP main camera and 8 MP front camera cover everyday photography needs, while features such as Water‑Lock mode, dock charging support, Widevine L1 certification and an enhanced service app improve usability. AI tools like on‑device writing assist, screen search and an AI calculator add convenience for communication and quick tasks.

Suitable for

  • Outdoor work and field jobs (construction, forestry, utilities)
  • Long trips and remote travel where charging is limited
  • Users who need a rugged phone resistant to drops, dust and water
  • Everyday photography and social media posting

When it may not be suitable

The RugKing 4 Pro is designed for durability and battery life rather than flagship-level performance or the highest display resolution. Users who prioritize the sharpest screen, top-tier gaming performance, or the lightest possible handset may find the 720 x 1612 display resolution and the device weight of around 405 g less suited to their needs.

Key specifications

  • Display: 6.56" (16.7 cm), 720 x 1612 pixels, Corning Gorilla Glass 3
  • Processor: Unisoc T7250 octa‑core, up to 1.6 GHz
  • Memory: 8 GB RAM (LPDDR4X), 128 GB internal storage, expandable via MicroSD up to 2 TB
  • Cameras: Rear dual camera with 48 MP main and 2 MP macro; 8 MP front camera
  • Battery: 10,200 mAh Li‑Ion, rated for long cycle life
  • Connectivity: 4G, Dual Nano SIM, Wi‑Fi (802.11 a/b/g/n/ac), Bluetooth 5.2, NFC, USB Type‑C
  • Operating system: Android 15
  • Durability: IP68, IP69K water/dust protection; MIL‑STD‑810H compliant
  • Other: Widevine L1 certification, dock charging support, Water‑Lock mode

How to use

Turn on the phone with the side power key and complete the Android 15 setup to sign in with a Google account if desired. Use Water‑Lock mode when operating the touchscreen in wet conditions to avoid accidental touches. Place the phone on the optional charging dock for convenient contact charging, or charge via the USB‑C port. Use the camera app for photos and the built‑in AI tools for writing assistance, screen search and handwriting calculation. Manage storage by inserting a MicroSD card if additional space is needed.

What to consider before purchase

  • Device weight (~405 g) and size due to rugged construction
  • Display resolution is 720 x 1612 — not Full HD
  • Network: 4G connectivity (no 5G support)
  • Choose storage variant or plan to use MicroSD for additional capacity

Usage recommendations

For best durability, use a protective case or strap when working at height, enable Water‑Lock before submersion or heavy rain exposure, and take advantage of the large 10,200 mAh battery for multi‑day trips. Keep the system updated to Android 15 patches and use the Service Center app for quick support and guides.
