Forget everything you thought you knew about rugged phones. Blackview OSCAL TANK 1 5G isn’t just another durable device that sacrifices performance for protection. It’s a technological fortress, a power station, and a multimedia hub rolled into one incredibly tough shell. Designed for extreme environments and power users who refuse to compromise, the TANK 1 declares war on limitations with a staggering list of specs that dominate both the outdoors and the spec sheet.

The Unbreakable Foundation: Built to Survive Anything
At its core, the TANK 1 is engineered for absolute resilience. It boasts IP68, IP69K, and MIL-STD-810H certifications, making it impervious to dust, dirt, sand, high-pressure water jets, and submersion. It can survive drops, shocks, and extremes of temperature that would instantly retire a conventional flagship. This is a phone for construction sites, mountain expeditions, and adventurous lifestyles where ordinary smartphones fear to tread.
The Power Revolution: A 20000mAh Behemoth with a Secret
The headline feature is its monumental 20000mAh battery – a capacity larger than many power banks. This isn’t just about days of battery life; we’re talking weeks on a single charge for moderate users. It obliterates range anxiety forever. But Blackview takes it further with 55W Fast Charging, ensuring you’re not waiting an eternity to refill this massive cell. The true game-changer? The Reverse Wired Charging function. The TANK 1 transforms into a literal power bank, capable of charging other devices, from your friend’s dead phone to your wireless earbuds, via a USB-C cable. It’s the ultimate team player on any adventure.

Innovation on Both Sides: The Dual Display Advantage
Breaking new ground for rugged phones, the TANK 1 features a Dual Display system. The front houses a vibrant 6.78-inch 120Hz 2.4K display—a screen with a resolution and smoothness that rivals mainstream premium phones, perfect for navigation, media, and gaming.
Flip it over, and you’ll find a secondary rear display. This ingenious feature lets you use the powerful 64MP main camera for flawless selfies and video calls, utilizing the superior main sensor instead of a lesser front-facing one. It also shows notifications, time, and controls music without needing to flip the phone. It’s a versatile tool for convenience and superior content creation.

Performance & Photography: No Compromises Here
Under the hood, it’s powered by the MediaTek Dimensity 7050 5G chipset, paired with a staggering up to 48GB of RAM (via expansion) and up to 512GB of storage. This combination delivers smooth 5G connectivity and robust performance for multitasking, demanding apps, and even mobile gaming. The 64MP AI-powered camera system, aided by Dual LED Flashlights (which double as emergency torches), captures clear, detailed photos and videos in challenging lighting conditions, from sunset landscapes to night-time campsites.
Modern Software & Extras
Running on the latest Android 15, it offers a clean, modern software experience with long-term update potential. The inclusion of NFC adds modern convenience for contactless payments, a feature often omitted in rugged devices. The dual flashlights are not just for photos; they are super-bright tools for emergencies or nighttime tasks.
