Have a laptop that has a 230 watt power supply. Do I risk something if I put the thing on a train or a coach?
If the connection fits then nothing happens. The train takes a little more than 230 BC to run.
Ask the train staff or the bus driver in advance. Then you are on the safe side.
Well, watt and volt are different
This is about the power in watts, not the voltage in volts.
If it is a protective contact socket (like a normal socket in the house) nothing should happen. It could be that no 16A comes out, so it may be that it does not get the full power for charging, does not bother, just takes longer
The maximum thing that could happen is that the fuse for the socket in question blows out and the socket is dead.
However, that would be a good question for people who know about trains.
As a rule, there's a sticker with the maximum power for the socket next to it. I also only know the power up to 90W max. So your power supply would overload the fuse and the socket fail… At the time they were introduced, hardly a laptop had more than 90W power supplies… They are not designed for today's high-performance computers, but for office laptops or cell phone chargers…
An outlet doesn't just deliver less. If the maximum permissible connected load is overloaded, the fuse blows…
Yes, of course, but I understood his question in such a way that he meant the tension!
In addition, a train does not run on 230 volts!
He writes watts and not volts. So it has a power supply that draws up to 230W power from the socket… A bit too much for the pull-out sockets…
If the motor / inverter can't deliver enough you can't use ~ 3.5kW but only less… Always the question of what security technology is installed
Then either the inverter switches off or it is appropriately protected and the fuse blows. The last possibility would be that the voltage collapses and the notebook's power supply unit simply no longer runs because the supply voltage is too low. What would not happen, however, would be reduced charging power so that it would take longer. The power supply tries to get what it needs. Either it works or it doesn't. But it doesn't work any slower in this case…
