Unihertz Tank 4 Pro: Specs, Price, and Is It Worth It?

The Unihertz Tank 4 Pro is one of the strangest phones you can buy today. It is a rugged 5G handset with a massive 11,600 mAh battery, an integrated DLP projector, and a 6.73-inch AMOLED display. In other words, it tries to be a phone, a power bank, and a pocket projector at the same time.

Most shoppers arrive with three questions: what are the real specs, how much does it cost, and is it worth the money. This guide gathers the verified specifications and prices, explains how the Tank 4 Pro differs from the regular Tank 4, and helps you decide.

Is the Tank 4 Pro Worth Buying? The Short Answer

Key Specs at a Glance

Unihertz Tank 4 Pro Full Specifications

The table below collects the core specifications from the manufacturer and reputable spec databases. Scroll it sideways on mobile if it is wider than your screen:

The Built-In Projector: A Big Screen in Your Pocket

The feature that sets the Tank 4 Pro apart is its integrated DLP projector. It can throw an image up to 120 inches onto a wall or any flat surface, turning a room into a small cinema or a simple presentation space. The projector supports autofocus and keystone correction, so you do not have to fine-tune the image by hand every time. The phone also supports connecting to an external display.

Continuous projection time reaches up to 4.5 hours according to the manufacturer. Real-world users include students, campers, travelers, and field professionals. Keep in mind that image quality and brightness depend on room lighting, so a projector like this looks best in a relatively dark space.

Battery and Charging: 11,600 mAh and 66W

The battery capacity is 11,600 mAh, which is far larger than most regular phones, and it is paired with 66W fast charging. The idea is simple: a big battery reduces how often you reach for a charger, but it also adds weight.

One point worth clarifying: a huge battery does not automatically mean a week of life in every condition. Actual runtime depends on your usage, how often you run the projector, screen brightness, and network signal strength.

Durability and Weight: IP68, IP69K, and 530 g

The phone carries both IP68 and IP69K ratings, meaning strong water and dust resistance, which is expected on a rugged device built for tough use. The trade-off is weight: 530 g and a thickness of 31 mm, roughly double the weight of a typical phone. If you work outdoors or in harsh environments, the bulk may be acceptable. If you want a daily pocket phone in the city, that weight is likely to bother you.

Performance: The Dimensity 8300

At the heart of the phone is the MediaTek Dimensity 8300, built on a 4nm process. It sits in the upper mid-range segment, which means solid performance for everyday tasks and moderate gaming, but it is not a flagship gaming chip. According to spec data, the CPU uses one Cortex-A715 core at 3.35GHz, three Cortex-A715 cores at 3.2GHz, and four Cortex-A510 cores at 2.2GHz, paired with a Mali-G615 MC6 GPU.

On memory, the base version offers 16GB of RAM with 512GB of storage, while the higher version offers 18GB of RAM with 1TB of storage, plus microSD expansion.

Tank 4 Pro vs Tank 4 vs Tank 3 Pro

Many shoppers mix up the Tank 4 Pro with the regular Tank 4. The differences matter before you buy:

As for the older Tank 3 Pro, its typical street price starts around $566 according to Kimovil data, which is lower than the Tank 4 Pro. If your budget is tight, it can be a reasonable comparison, but it is a full generation behind.

It is also worth noting that the Tank 4 Pro is not the newest model in the family. The Tank 5 was announced on June 16, 2026, and the Tank 5 Pro followed on August 23, 2026, with a wide-angle FLIR thermal camera. So if you want the latest option, something newer than the Tank 4 Pro already exists.

Price and Availability

On the manufacturer's official store, the Tank 4 Pro is listed at $709.99 as a sale price, against a base price of $929.99, and the store page shows only 2 reviews. The available regions listed on the official site are US, EU, CA, UK-AU-NZ, and Asia.

On price-comparison sites, the street price starts around $804 for the 16GB + 512GB version and around $835 for the 18GB + 1TB version, with a release date of July 2025 according to Kimovil.

Who Should Buy It, and Who Should Skip It

Frequently Asked Questions

Are the Tank 4 Pro and Tank 4 the same phone?

Answer: No, they are different. The Tank 4 Pro uses a Dimensity 8300, a projector up to 120 inches, and a 6.73-inch display, while the regular Tank 4 uses a Dimensity 7300, a 720p DLP projector, and a 6.78-inch display.

How much does the Unihertz Tank 4 Pro cost?

Answer: On the official store it is listed at $709.99 as a sale price, against a base price of $929.99. On comparison sites, the street price starts around $804 for the 16GB + 512GB version and around $835 for the 18GB + 1TB version, and it varies by region and time.

Does the 11,600 mAh battery really last several days?

Answer: Not necessarily. A bigger battery gives you longer use, but actual runtime depends on how often you use the projector, screen brightness, network signal, and your usage patterns. The number alone does not guarantee a fixed number of days.

Is the built-in projector actually practical?

Answer: Yes, if you will really use it. It projects up to 120 inches with autofocus and keystone correction and up to 4.5 hours of continuous projection, but it works best in a relatively dark room. If you will not use projection, you are paying for a feature that will not help you.

Is the Tank 4 Pro the newest phone in the lineup?

Answer: No. The Tank 5 was announced in June 2026 and the Tank 5 Pro in August 2026, and the newer Pro model adds a wide-angle FLIR thermal camera, so the Tank 4 Pro is not the latest release.

Final Verdict

The Tank 4 Pro is a phone that breaks the mold: an 11,600 mAh battery with 66W charging, a projector up to 120 inches, a 120Hz AMOLED display, IP68 and IP69K ratings, and a Dimensity 8300 chip. The bottom line is that it is genuinely worth buying if your needs match its specialized strengths, but it is not the best choice for most everyday users.

The key advice: before buying, honestly answer three questions. Can you live with 530 g? Will you actually use the projector? And does your budget allow for a price that starts around $710? If you answered yes to at least one, it deserves a closer look. If not, there are thousands of better-fitting options. And before any decision, confirm the current price and availability on the official store, because prices change.
