In an era where smartphones are increasingly designed for sleekness and minimalism, 8849 has once again disrupted the market with a bold, no-compromise device — the 8849 TANK 4. This rugged smartphone combines military-grade durability with cutting-edge features, including a built-in projector, 64MP night vision camera, 11600mAh high-capacity battery (Model: PBA98116), and dual IP68/IP69 waterproof and dustproof ratings, making it one of the most powerful outdoor-ready smartphones of 2025.

Design & Durability: Built for the Extremes

The 8849 TANK 4 features a rugged, armor-like design measuring 174.3 × 85.4 × 23.9mm and weighing 538g (with battery), delivering a solid, tank-like feel. Constructed with reinforced composite materials and a metal frame, it’s engineered to withstand harsh environments.

Its standout durability features include:

• IP68 & IP69 Ratings: Fully dustproof and capable of withstanding immersion in 1.5 meters of water for over 30 minutes. It also resists high-pressure, high-temperature water jets, ideal for industrial cleaning or extreme weather.

• Shockproof & Drop-Resistant: Built to survive repeated drops and impacts.

• Black Finish: Sleek, professional, and highly functional for outdoor and field use.

  

Display & Performance: Power and Clarity

Despite its rugged nature, the TANK 4 delivers a premium user experience:

• 6.78-inch 2.6K AMOLED Display with 1200×2650 resolution and a 120Hz refresh rate ensures smooth scrolling, vivid colors, and excellent outdoor visibility.

  

• Powered by the MediaTek Dimensity 7300 (MT6878), built on a 4nm process with a 2.5GHz octa-core CPU, it delivers strong mid-to-high-end performance.

  

• 12GB RAM + 512GB ROM provides ample memory for multitasking, apps, and media storage.

  

• Ships with Android 14, offering the latest in security, customization, and AI features.

Camera System: See Beyond the Dark

The TANK 4’s camera setup is tailored for extreme conditions:

• 50MP Main Camera with autofocus for sharp, detailed photos

• 64MP Night Vision Camera — a standout feature optimized for low-light and nighttime scenarios, perfect for security, exploration, or night photography

• 8MP 3x Optical Zoom Telephoto Camera with AF for distant subjects

• 32MP Front Camera for high-quality selfies and video calls

  

This combination makes it ideal for adventurers, field workers, and anyone needing reliable imaging in challenging lighting.

Revolutionary Feature: Integrated DLP Projector

One of the TANK 4’s most innovative features is its built-in DLP projector:

• 720p Resolution (1280×720)

• 100 Lumens Brightness — suitable for dimly lit environments

Whether you're camping, giving a field presentation, or watching movies outdoors, the projector turns any surface into a big-screen experience — a rare and valuable feature in any smartphone.

Battery & Charging: The PBA98116 Powerhouse

At the heart of the TANK 4 lies the 11600mAh PBA98116 battery, a custom-designed power cell built for endurance and reliability in extreme conditions.
