The Ulefone RugKing 4 Pro is a high-capacity rugged smartphone engineered for extended use in demanding environments. The 10,200mAh battery delivers long-lasting power for outdoor adventures or lengthy work shifts, supported by 18W wired charging, 10W dock charging, and 6W wired reverse charging to top up small devices on the go. Built to survive where other phones cannot, the RugKing 4 Pro holds IP68 and IP69K ratings for water and dust resistance alongside MIL-STD-810H certification for drop and extreme-condition protection.

The 6.56-inch HD+ display runs at a 120Hz refresh rate for smooth scrolling and visual performance, and is shielded by Corning Gorilla Glass 3 against scratches and impacts. A dedicated Water-Lock Mode disables the touchscreen in wet conditions to prevent accidental inputs from rain or moisture, while Glove Mode keeps the screen responsive when wearing work gloves.

Performance is driven by a Unisoc T7250 octa-core processor paired with 8GB of LPDDR4X RAM, expandable via software to 16GB. The 256GB of UFS2.2 internal storage can be expanded by up to 2TB via a microSD card (not included). The phone runs Android 15, which brings enhanced security features including theft detection and private data spaces.

The rear camera system combines a 48MP main sensor with an f/1.8 aperture and a 2MP macro lens for close-up photography. An 8MP front camera handles video calls and portraits. A 120-lumen Super Torch provides reliable illumination in dark settings without needing a separate flashlight.

Please note: No USB charger is included in the box. Use an existing USB Type-C charger or a compatible 18W USB-C power adapter.
