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

Built to take on the toughest assignments, this rugged handset pairs a 20000 mAh ExploVolt battery with 55W fast 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 for resistance to water, dust and heavy drops.

Unlimited battery life and twin lighting

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

Dual display for the outdoors

The primary screen reaches 700 nits so it stays legible in sunlight, while the secondary rear panel displays alerts and music controls without turning on the main display, which saves energy.

5G performance and expandable memory

The 6nm MediaTek Dimensity 7050 provides 5G dual SIM and good thermal efficiency; the 12GB of physical RAM extends to 24GB through Turbo RAM and the 256GB UFS 3.1 storage accepts a 2TB microSD card.

Flexible cameras with night vision

The rear setup pairs a 64 MP main sensor with a 20 MP IR unit for shooting in complete darkness; the 50 MP front camera guarantees sharp video calls.

Ruggedness and complete connectivity

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

Our expert's verdict

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 light, neither of which they have. Those rivals either last less on a charge or do without night vision. Next to the earlier Oscal S80, it adds 5G, a 120 Hz refresh rate and the move up to the Dimensity 7050, cutting charging times despite the higher amperage. It weighs nearly double a standard smartphone and its bulk is not pocket-friendly, yet its mix of toughness, versatility and value for money makes it the reference choice for field professionals and adventurers who need days of unplugged work and a device that survives what others cannot.
