Built-in projector rugged phone

The Unihertz Tank 3S is a factory-unlocked Android smartphone with a 6.79-inch display and an integrated DLP projector. It ships with 16GB of physical RAM and 512GB of internal storage, plus a microSDXC slot for expansion. A 15600mAh battery powers the device, which carries IP68 certification for dust and water resistance.

Suited for field workers needing projection

Professionals who present on-site or need a portable display in rugged conditions gain a single device that replaces a phone and a pico projector. Buyers who want a slim handset or a lighter daily driver should look elsewhere, as the large battery and rugged chassis add considerable bulk.

15600mAh battery capacity

The 15600mAh cell is the specification that determines whether this phone meets a user's endurance requirement. It supports extended projection sessions and multi-day standby without recharging. If that capacity exceeds what is needed, a smaller rugged model may be more practical.

Questions about this item

How much RAM and storage does this model include?

The phone ships with 16 GB of physical RAM plus up to 16 GB of virtual RAM and 512 GB of internal storage.

What does the 15600 mAh battery mean for daily use?

The 15600 mAh capacity supports extended outdoor use and multi‑day standby between charges.

What does the 59 Hz refresh rate cap in practice?

The 59 Hz panel limits on‑screen motion to 59 frames per second, so fast scrolling and gaming appear less fluid than on higher‑rate displays.
