Is it possible to insert AC POWER ADAPTER 24V - 0.2A into a device that says Input DC 12V - 1A?

Question

Electronics

I'm just starting to understand all this, and I still do not understand. I inserted such an adapter into the router and it works, but are there any consequences? I would be grateful for an answer or a link to a resource where I can understand the principle

Answer 1

Not allowed. The magic smoke on which it works will come out of the device, and you will need to go to the service so that the new smoke is uploaded.
When throwing a non-standard power supply, you can only overestimate the current (which is the letter A), but not the voltage (which is V).
The voltage must exactly match the one that the device consumes, the current on the block may be more than what the device needs.
This is all true for conventional power supplies! Never try to fit into a router or laptop, for example, a power supply for LED! Such a block is a source of current, not voltage, it will try to raise the voltage until the current reaches the setting, and most likely burn the electronics to coals.
If you overestimate the voltage, the device will either immediately bang, or the input capacitors will flow in it, and it will start working after a time. Of course, there is another option that will work - this is if the developers of the device are so thrifty that they shoved a capacitor with a threefold margin at the input.

Answer 2

No. The voltage cannot be increased.
The fact that it works is quite possible - but this is not a regular mode, both for the router and for the adapter. The consequence is simple - overheating.

Answer 3

It is forbidden. The voltage of the power supply must be 12V, the output current is not less than 1A.
You now have an increased voltage, which threatens to damage the router, and a possible current overload of the power supply, which, accordingly, can lead to damage to the power supply.

Answer 4

in most cases it is not possible.
because the capabilities of the input power converter in the device are not known.
but knowing it is quite possible.
I had a netbook with a 12v power supply and an 18v charger.
at first I put on a lowering at 7812 and everything worked, though it was terribly warm and it was massive because of the large radiator.
then I found a schematic diagram of a netbook, by marking the input PWM converter, I found out that it can perfectly eat from 9 to 24 volts, looked at the input circuits, there were no problems with 18 volts either and began to connect the netbook directly - everything worked fine.

Answer 5

Can. But it will burn
