What is the 8849 Tank 3 Pro?

The 8849 Tank 3 Pro (also known as the Unihertz Tank 3 Pro) isn’t just another rugged smartphone, it’s an all-in-one mobile powerhouse built for extreme conditions. This phone packs a 23,800mAh battery, a 200MP main camera, night vision lens, built-in DLP projector, and military-grade durability. It’s designed for adventurers, outdoor professionals, and anyone who needs more than what a regular smartphone offers.

With IP68 and MIL-STD-810H certification, it’s dustproof, waterproof, shock-resistant, and ready to survive harsh environments. Powered by the MediaTek Dimensity 8200 processor with up to 36GB of RAM (including extended virtual RAM) and 512GB storage, it easily handles demanding apps, games, and multitasking.

Standout Features

Here’s what makes the 8849 Tank 3 Pro stand out in the crowded rugged smartphone market:

1. Massive 23,800mAh Battery with 120W Fast Charging

Battery anxiety is a thing of the past with this monster. The phone can last several days on a single charge and supports 120W fast charging that can take it from 0 to 50% in under 40 minutes. It also offers reverse charging, letting you use it as a power bank for other devices.

2. Built-in DLP Projector

The Tank 3 Pro’s integrated projector is a rare and game-changing feature. With a brightness of around 100 lumens and manual focus, you can project presentations, videos, or movies onto any flat surface. It’s ideal for business meetings, camping trips, or entertainment on the go.
