Xiaomi started working on the new gadget two years ago, immediately after the cancellation of the release of AirPower, Apple’s accessory that promised to charge several devices wirelessly at the same time.
Easily noticeable for those with minimal knowledge about the operation of wireless charging devices, the mistake made by Apple was to ignore the limitations inherent in this technology. Instead of using a single inductor for wireless power transfer, Apple engineers have provided no less than 14 such inductors.
The problem is that the wireless charging technology is not 100% without power losses, each such inductor having its own consumption, which can increase even more if the powered device has its own inefficiencies on the wireless charging side. Totally unhappy for Apple, the company had such a product in its fixed portfolio. Designed to be as compact as possible, the Apple Watch does not have a very efficient inductor for wireless charging, but it compensates for this by requiring a higher power supply from the adapter used. This is how, when charging Apple Watch devices, the AirPower adapter turns into a mini electric hob, the 14 inductors consuming much more energy than what actually reached the Apple Watch battery.
Although we never found out exactly how much energy the AirPower accessory wasted for the convenience of a wireless charging system that works in any situation, we can assume that the gadget was inefficient enough to question Apple’s reputation as a “green” company.
The wireless charging mat developed by Xiaomi, even more ambitious than the one abandoned by Apple
Presented as a far superior interpretation of the Apple AirPower accessory, the new gadget increases the number of inductors from 14 to 19 and promises to power up to 3 devices simultaneously, each receiving 20W of charging power.
Compatible with third-party devices as well, the new Xiaomi adapter promises to permanently eliminate the complications of power cords, providing fast charging for any compatible device.
However, before making plans to buy the accessory for $ 90, maybe we should wait for concrete details about the possible disadvantages. Especially in the case of high-power wireless charging adapters, the heat generated during power transfer can be a cause for concern in terms of shortening the battery life. Last but not least, a convenient gadget to use is not necessarily environmentally friendly. If a significant proportion of the electricity used is wasted as heat, then we also return to the reason why Apple chose to abandon the launch of the AirPower accessory. By stopping the launch of a sub-standard quality product, which once released would have sold millions of copies, Apple avoided releasing a not inconsiderable amount of greenhouse gases into the atmosphere.
Assuming that it is indeed much more sophisticated and environmentally friendly than the gadget it imitated, the Xiaomi Wireless Charging Pad can be ordered for $ 90, offering a stylish and very practical solution for those who own more devices that support wireless charging.
Alternatively, you can also order the Mi Wireless Charging Stand Set, taking the form of a stand that allows you to place your mobile phone in a convenient position for inspecting on-screen notifications. Equipped with an integrated ventilation system, the device can support up to 80W of charging power in wireless mode, shortening the waiting time when using a phone that meets these specifications to less than an hour.
