The Oscal Tank 1 has a 20,000 mAh battery with a claimed standby time of 1,080 hours, and it claims to have 48GB of RAM, but it’s a little more complicated.
Some gadgets are designed to be sleek and pretty. The Oscal Tank 1 phone is not one of those. The entire thing is built around a battery so big it competes with power banks — and not those modest 5,000mAh units either. We’re talking about a 20,000mAh ExploVolt power cell that promises an absurd 1,080 hours of standby time.
You could probably get through an entire weekend camping trip without ever thinking about a charger. All that juice is crammed into a chassis that weighs a staggering 640 grams, making it about as heavy as four average smartphones. The over-the-top specs don’t stop there, with the phone’s most eye-popping claim being its supposed 48GB of RAM.
Its ruggedness is also just as bonkers. The phone boasts top-tier IP68 and IP69K waterproof ratings alongside a military-grade MIL-STD-810H certification. These ratings have become something of a standard for durable phones — the Oukitel WP 300 we recently reviewed featured them too, but Oscal also claims the Tank 1 can survive 10-meter, or 50-foot free falls and shrug off 1,200 kilograms (over 2,600 pounds) of pressure.
