The OSCAL Tank 1 is an ultra‑rugged 5G smartphone made for extreme conditions, and it benefits from a 4‑year warranty, giving you long-term protection.

The phone is built like a tank: it meets IP68, IP69K, and MIL‑STD‑810H standards. At its heart is a massive 20,000 mAh battery, with 55 W fast charging (wired and dock) plus 5 W reverse charging, making it a beast for endurance.

The main screen is a 6.78‑inch IPS panel with 2.4K resolution and a smooth 120 Hz refresh rate, protected by Gorilla Glass 5, and there’s a secondary 2.01‑inch screen on the back for quick-glance information.

Inside, it runs on a MediaTek Dimensity 7050 5G processor, with either 12 GB RAM (plus up to 24 GB virtual) or 16 GB RAM (plus up to 32 GB virtual), paired with 256 or 512 GB of internal storage, expandable via microSD up to 2 TB. For photos, it has a 64 MP main camera, a 20 MP night-vision camera, and a 50 MP front camera.

The phone weighs 640 g and measures 184 × 83 × 29.5 mm — but its rugged build and huge battery make it ideal for users who need extreme durability and long-lasting power.
