[Hardware] - Motorola demonstrates wireless remote charging with 4 devices simultaneously

[Angrry.exe™]

Motorola, like other smartphone makers such as Xiaomi, Huawei and Oppo, is working on remote wireless charging technology. Its solution is called Space Charging and it was announced some time ago. Now, the company comes up with a hands-on demonstration of the technology, featuring a charging station that can power up to four devices simultaneously, at distances of 1, 2 or 3 meters.

Motorola's Space Charging can power four devices at once

Motorola's official Weibo account has released a short clip of a few seconds showing various use cases for Space Charging technology. The charging station looks like an internet router with a slightly larger housing, which integrates 1,600 antennas, used to power remote phones. The signal they send can pass through paper and other small obstacles, but not through larger ones.

Interestingly, however, the device is smart enough to be able to turn off the power in certain areas if a person's presence is detected there, suggesting that transmitted electromagnetic waves could somehow affect the human body. Otherwise it would not have been necessary to turn off the power. Motorola has also revealed that the Space Charging station will be able to power phones at a 100-degree angle in front of it. Basically, it is confirmed that we are talking about a "line of sight" technology, requiring direct visual contact between the charger and the phone.

Even if Motorola did not provide official information about the charging speed, according to Digital Chat Station, this solution will be limited to charging at 5W. By today's standards, this power is very low, and devices with large batteries would charge extremely slowly from 0 to 100%, but the mode of operation of Space Charging could be rather oriented towards slow charging.

Uploading will be slow but steady

First of all, it is assumed that you will put such a charger in a room where you are present for long periods of time. Thus, the phone could be permanently powered at 5W. During a full day's work, for example, the phone may remain at 100% at all times, regardless of usage level. Moreover, fast charging heats the devices, thus adversely affecting the batteries.

At the moment, neither Motorola nor other companies offer a deadline for the launch of wireless remote charging technology. However, given that these technologies are being demonstrated more and more often, it probably won't take long for them to launch. On-screen camera integration technologies began to be demonstrated about two years before the first devices were launched on the market, for example.
