I think for many users it will be important such a device. In the search I found a couple of links, but the topic was not fully disclosed.
Vegavolt D-421
Charges everything and replaces all other chargers. Recognizes the type and model of devices connected to it for charging, displays them on the mini display screen, automatically generates and supplies the current and voltage necessary for it.
The Vegavolt D-421 model is completed with a network power supply unit, a connector for connecting to a car cigarette lighter, an extension cord, three connectors for connecting powered or charged devices. Can charge only 2 devices at a time.
When buying a charger, you can choose any three connectors. Additional connectors are purchased separately.

The device can be connected to any power source of both AC voltage from 110 to 240 V and DC voltage of 10 to 20 V. That is, when traveling, it can be connected, for example, to a laptop power supply unit.
In my opinion, this device is just created for use on trips, because 2 connectors for rechargeable devices are not enough for permanent use. Although, knowledgeable people (owners of the device) argue that the need to charge more than two devices at the same time is extremely rare.
The price of the device at the moment is 1500 minus one ruble.
