Xiaomi Launches A Modern Digital Walkie-Talkie With Color Screen, Range Of Up To 5 Km And A 100-Hour Battery Life. Water And Dust Resistant, It Combines Nostalgia And Innovation For Civilian And Professional Use

The Chinese giant Xiaomi, recognized for its strength in the global smartphone market, surprised everyone by launching a device that mixes nostalgia and modern technology: a digital walkie-talkie with a compact design, color screen, and a battery life of over 100 hours.

A Military Technology That Lives On

The first walkie-talkies emerged in 1940, created for military use by the company that would later become Motorola. Over time, they transitioned to civilian use, becoming icons of the 1980s.

Even with the popularization of mobile phones, this technology has never disappeared and continues to be used by police, firefighters, and armed forces all over the world.

Classic Design With Smart Features

The Xiaomi Digital Walkie-Talkie maintains the “candy bar” shape with a protected antenna, but is much thinner than traditional devices.

It features a 1.57-inch color LED screen (320 x 200 pixels) that displays contact information, settings, and notifications. It also has IP54 certification, making it resistant to dust and water splashes, ideal for outdoor use.

The device can be managed through the Xiaomi Intercom app, which allows you to configure contacts and even view the relative position of the person you are communicating with.

Moreover, it is compatible with Bluetooth headsets and has an integrated 36 mm speaker, ensuring clear calls even in noisy environments.

Range Of 5 Km And Up To 100 Hours Of Battery

Xiaomi utilized FDMA (Frequency Division Multiple Access) technology to enhance communication clarity, providing high-definition audio and reducing interference.

The range reaches up to 5 kilometers in open areas or covers spaces of up to 10,000 m², such as shopping malls or industrial complexes.

The battery is another highlight: with a 2,500 mAh capacity, the walkie-talkie guarantees up to 100 hours on standby or about 14 hours of continuous use.

Charging is done via USB-C, and the device can be used while charging, an important advantage for long journeys or intensive operations.

Libya built over 4,000 kilometers of underground pipelines to bring water from the Sahara to coastal cities in a project that the government itself called the Eighth Wonder of the World.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Toyota launches “family hybrid van” with 7 or 8 seats, 1.8 hybrid engine, fuel consumption of up to 23.8 km/l, and a price equivalent to about R$ 104,000 without taxes, below the Tiggo 8 Pro Plug-in Hybrid sold in Brazil: meet the Noah Hybrid 2026 in Japan.

Described by astronauts as one of the most unlikely natural phenomena on Earth, the Okavango Delta spreads over up to 15,000 square kilometers in the middle of the desert and transforms Botswana into a living labyrinth of channels, islands, and flooded areas.

Scientists have created a material six times lighter than air, 75 times lighter than styrofoam, and that becomes stronger the more it is compressed: aerographite seems impossible, but it can reinforce structures, batteries, and satellites.

System created to save lives in disasters turned ‘against’ Brazilians overnight: a hacker attack sent out a false alert from Civil Defense with the word “misantropia” that went off on the phones of half the country, even in silent mode, and took down the Cell Broadcast.

NASA captured by satellite an underwater volcano erupting in the Bismarck Sea, in the Pacific, and now scientists are waiting to see if a new island will be born there in front of the cameras, a very rare phenomenon to witness live from space.

The Atacama Desert, the driest place on Earth, was covered in flowers and turned into a colorful carpet with more than 200 species in the phenomenon called “desert bloom,” when atypical rains awaken seeds that had remained dormant in the soil for many years.

In the cold desert of Ladakh, where it hardly rains, engineer Sonam Wangchuk created the ice stupa, a tower that freezes winter water and stores it for irrigating crops in the spring, a simple engineering feat that mimics nature.

For the first time in history, solar and wind energy generated more electricity than natural gas worldwide in a single month, April 2026, a milestone in the energy transition that shows renewable sources taking the lead in the global electric system.
