Yes, the 250 volt rating refers to the insulation rating factor of the cord and the maximum amount of voltage potential that the cord can safely handle.
No way of telling, but you certainly fried the AC adaptor.
It could be a problem when the laptop asks for 4.74 amps and the adaptor can't do that without heating up too much.
Check the output voltage and mA capacity on the nameplate of the adaptor. The adapter will be useful on devices at that DC voltage and up to the mA capacity of the adaptor E.g. the nameplate may read Input: AC120 volts 5 watts. Output: DC 12 volts 200 mA.
You will need a power adaptor.
it take 24v
Do you mean a 220V as in a power in Europe? Then,Check your adaptor. It will tell you the input voltage. If it sates that the range of the input voltage in 100V-240V then YES you can plug in your adapter into a 220V outlet.Please note that some people advise that you plug in the adapter into the power before plugging it into the computer.
230 / 240 volts
at Argos, Masterplug 1200mA Multi-Volt Adaptor you will need to set to 9 volts
THEY ARE PROBABLY ONE AND THE SAME The key is that Europe is 220 volts and USA is 120 volts. The plugs also have different shapes. Therefore, the "gadget" must change the voltage AND change the prong configuration.
Usually the power (in watts) is close to the product of volts x amperes.
Either 120 or 220 volts, depending on what part of the world you are in. If you are in the United States, most power coming out of a wall socket is at 120 volts. In Europe and elsewhere, its at 220 volts. This is why if you are traveling abroad with US-based electronics you need a converter to use them in other countries.
No, Your original adaptor has an output of 3 amps or 3000 ma. As you can see, the one you want to use for a replacement adaptor only has 1000 ma output, one third of the current capacity that you need.
