Charging Xiaomi, which itself is looking for a socket: myth or new reality?

In an era of rapid technological advancement, the line between science fiction and reality is getting thinner. Users are often confronted with viral videos showing off devices that can work wonders, and the recent hype surrounding Xiaomi’s alleged charging system, which crawls around the apartment on its own looking for an outlet, is a prime example. This statement sounds like a joke, but it’s based on a real interest in wireless technology and home automation.

In fact, Xiaomi has not yet released a commercial product that physically moves across the floor in the form of a snake or a robot vacuum cleaner to connect to the network. However, the confusion did not arise from scratch: the company’s engineers are really developing revolutionary remote charging systems that allow devices to charge at a distance without physical contact.

In this article, we will discuss in detail where the legs of this misconception grow, what real Mi Air Charge technologies are already available or being tested, and what Xiaomi’s smart home ecosystem really knows. Understanding the principles of these devices will help you avoid becoming a victim of marketing tricks of scammers and competently build your energy consumption system.

Where did the myth of the crawling adapter come from?

Rumors that Xiaomi has created an adapter that looks for a power source on its own began to circulate after a demonstration of the Mi Air Charge concept technology. Video footage showed the smartphone charging from a few meters from the base station. People, without going into technical details, interpreted "search for a signal" as the physical movement of the charger itself.

Another cause of confusion was smart home products like charging robot vacuum cleaners or voice-controlled smart outlets, where when a user tells an assistant to “turn on charging” and the lights go on, the illusion of magical control of electricity is created, but in fact it is a complex system of sensors and software algorithms, not magic.

It's important to understand the difference between physically moving an object and transferring power through the air. While the former requires mechanical parts, wheels, and complex navigation, the latter is based on phased arrays, and Xiaomi has chosen the latter, which is much more efficient and safer for household use.

Mi Air Charge Technology: How It Really Works

The real technology behind the rumors is called the Mi Air Charge, which allows power to be transmitted up to several meters away without the use of wires or charging pads. The base station, the size of a router, contains a phased array of 144 antennas that form a narrowly-directed millimeter wavelength beam.

Inside a smartphone or other device, there's a miniature coordinate antenna that sends a signal to the base station, and the system, in real time, locates the gadget in space and directs energy to it, and this allows you to charge the device, even if you hold it in your hand or carry it in your pocket as you move around the room.

The key here is spatial positioning, which ignores obstacles like walls or furniture, focusing only on the receiver, which is very different from induction charging, which requires tight fit, and is still in the process of being actively tested and implemented in flagship models.

💡

Mi Air Charge technology is safe for health, as it uses low power and automatically turns off when foreign objects are detected in the beam zone.

Real Xiaomi gadgets with the function of “smart” charging

While there are no running power supplies, Xiaomi offers a variety of devices that make charging as comfortable and automated as possible, most notably wireless charging stations that can be built into furniture or smart lamps. For example, some Xiaomi nightlife models have a built-in charging area for smartphones.

And robotic systems like the Xiaomi Vacuum, which, although they don't wear chargers, they autonomously return to the base to recharge when the battery level drops, which is the smart socket-finding feature, but implemented through the robot's navigation, not through the adapter.

To create a complete ecosystem, users often combine different devices, and smart sockets allow you to remotely turn on and off the power of conventional chargers, creating the effect of energy management by clicking your fingers or voice command via the Mi Home app.

Comparison of wireless energy transmission technologies

To better understand Xiaomi’s place in the world today, we need to compare different approaches to wireless charging. The induction method that has become the Qi standard requires close contact. The RF method used in the Mi Air Charge allows power to be transmitted over distances, but with less efficiency.

Laser charging, which some companies are also testing, requires line of sight and is dangerous to the eyes, so Xiaomi is betting on radio waves.It is a safer and more versatile option for a living space where people and animals are constantly moving.

The following is a table comparing the main characteristics of the different charging methods available on the market or in development:

As you can see from the table, Xiaomi’s technology sacrifices efficiency for freedom of movement, but for the background charging of gadgets during the day, this is enough to ensure that the device never completely discharges.

Setting up a smart power system in Mi Home

Even without futuristic running charging, you can create a smart energy management system, you'll need a Xiaomi hub and smart outlets, and you can customize scenarios in the Mi Home app that mimic the intelligent behavior of the system.

For example, you can create automation: “If it’s 23:00 and your phone is connected to Wi-Fi, turn on a smart socket in the bedroom,” which will allow you to charge your gadgets only at night at a reduced rate or just to keep them constantly under voltage.

For advanced users, integration with voice assistants is available, and you can say, "Alice, turn on the charging," and if the smart socket is named accordingly, it will power, and this creates the kind of magic effect that users dream of.

💡

Automation through smart outlets is the most affordable way to make a conventional charger part of a smart home without buying expensive new equipment.

Safety and efficiency of use

Using any wireless technology, especially electricity, requires security measures, and while Xiaomi has many security mechanisms in place, such as temperature control and detection of foreign objects, basic operating rules cannot be broken.

It is not recommended to clutter the space between the base station and the device with metal objects, as this can cause heating or reflection of the signal. It is also important to use certified cables and adapters if your system involves wired connection of the base to the network.

⚠️ Warning: Never try to disassemble wireless charging stations or modify their circuitry on your own. There may be charge-saving capacitors inside, and a leakproof housing could deprive the device of dust and moisture protection.

Charging efficiency can be reduced by interference from other wireless devices. Wi-Fi routers, microwaves and Bluetooth headsets operate in similar frequency bands. Optimal base station location is on high ground, away from sources of strong electromagnetic fields.

The prospects of development of Xiaomi technologies

The future of charging devices is definitely no wires. Xiaomi continues to invest in research, and it is likely that in a few years we will see rooms where charging happens automatically as soon as you enter a room.The concept of "charging that looks for a socket" can transform into "the socket that looks for a device."

The Mi Air Charge will go the way of increasing power and range, and there is already talk of charging laptops and more energy-intensive devices at a distance, opening up new possibilities for interior design, where wires will finally disappear forever.

In the meantime, we're left with hybrid solutions: fast wired charging, convenient wireless docking stations, and the first swallows of real air charging. Keep an eye out for updates on the company's official blog to see if fiction becomes standard.
