Charger of laptop 110-240 V [duplicate]

I have a Toshiba laptop. The charger of my laptop says that the output is from 110-240 V.

Can I plug my charger to a 220 V without damaging it and do I still need an adapter?

I'm too scared to try it to plug it in a 220 V. I'm using 110 V all these times though.

Best Answer

Yes, your charger can accept 220 V mains power. You will need an adapter because the shape of the plug is very likely different. A simple adapter doesn't do anything to the voltage, it just offers a different shape of plug. (There are adapters that change voltage, but they are larger, more expensive, uncommon, and you don't need them for a laptop.)

For example, you might have a "Type A" plug (used in the US):

and you might be trying to plug it into a French socket:

A simple adapter which should cost maybe $10 will do the job.

Does my laptop support dual voltage?

An AC adapter supplying electricity at a higher voltage than required will cause the connected device to run hotter. Sending power at a higher voltage will also shorten the lifespan of the device and may fry its internal circuits. Using an AC adapter with a different current rating can be an issue.

Can I use a charger with higher voltage than the original?

Using a charger with the wrong voltage rating can potentially damage your laptop. This is typically caused by too high voltage. But using a charger with too high current won't damage your laptop. Using a charger with too low current rating might fry the power supply, but not the laptop.

What happens if you use the wrong charger for your laptop?

The short answer is yes you can use a laptop charger with a higher wattage, however, there are some caveats. The wattage rating of a laptop charger is a maximum rating which means that the charger is capable of providing power up to the output wattage rating and or course anything in between.
