Oscal Tank 1 5G, 12GB 256GB, 6.78 LCD IPS FHD+, 20000mAh, Black

Built for the toughest assignments, this robust handset pairs a 20000 mAh ExploVolt battery with 55W rapid charging that also works as a power bank, a 6.78" 120Hz 2.4K IPS 2.78" IPS screen with a 2.01″ rear panel, and a chassis certified to IP68/IP69K and MIL-STD-810H against water, dust and severe impacts.

Long-lasting battery and twin light

The 20000 mAh cell delivers days of heavy use; reverse charging protects other devices, and the 170 lm LED torch can replace a professional headlamp for camping or night shifts.

Two outdoor screens

The primary panel reaches 700 nits for readability in sunlight, while the rear display shows notifications and music controls without waking the main screen, saving power.

5G performance and expandable memory

The 6nm MediaTek Dimensity 7050 provides 5G dual SIM and thermal efficiency; the 12GB physical RAM expands to 24GB through Turbo RAM, and the 256GB UFS 3.1 supports 2TB microSD.

Flexible cameras with night vision

The rear setup pairs a 64 MP main sensor with a 20 MP IR for shooting in complete darkness; the 50 MP front lens guarantees crystal-clear video calls.

Toughness and complete connectivity

The rugged body resists high-pressure jets and extreme temperatures; it includes Wi-Fi 6, Bluetooth 5.2, NFC and quad GNSS for accurate positioning.

What our expert says

The Oscal Tank 1 beats the Doogee V30T (10800 mAh) and the Oukitel WP33 Pro (22000 mAh) in survivability thanks to the rear screen and 170 lm torch, both of which are missing. Their rivals offer less battery life or lack night vision. Compared with the previous Oscal S80, it gains 5G, a 120 Hz refresh rate and the move to the Dimensity 7050, cutting charging times despite the higher amperage. It weighs nearly twice as much as a standard smartphone and its size defies pockets, but its balance of ruggedness, multi-tooling and value for money makes it the benchmark for field professionals and adventurers who need days of unplugged work and a device that will stand up to what others can't.
