Japanese voltage 100 volt with 50 hz cycle.

[techs]

Japan, according to the internet, uses 100 volts instead of the USA's 120 volt. Plus parts of Japan use 50 hz instead of the USA's 60 hz.
Can I safely use my laptop power adapter with out a voltage converter?
Thanks.

Did you read the information on the AC adapter? It will tell you exactly what it can handle.

uhh i doubt it

If you try, you'll rip a hole in the space time continuum

 

[Demon-Xanth]

Most likely.

No, unless of course you have two things checked.
1. A compatible Plug
2. Checked the label to see if it supports 50hz , 100V operation.

 

[JohnCU]

it's a simple case of RTFM. or RTFL.

The power adapter would be all like "Woah, what the ****** is this? 120V? ****** that, I'm leaving!"

But perhaps not, I have a Japanese headphone amp that's apparently 50/60Hz capable. Might have been tweaked to comfortably support a higher voltage however. When you consider that the adapter has to consider some level of voltage fluctuation, it's not unreasonable to assume a good chance it could handle 120V.

If it were me, I'd try it.

I have done it without problem with a laptop.

Virtually all laptop power supplies can handle a range of voltages and either 50 or 60 Hz. But, do check the stats on your personal power supply (mine all say the stats it can handle right there on the bottom of the power supply). One thing to remember, is that 3 prong plugs (with the ground) are quite rare in Japan. You probably will be able to find one, but there is a chance that you might not have access to one. So bring a 3-prong to 2-prong adapter just in case.

depends. on some things yes. but for example, my mom had this Kitchen Aid Artisan Mixer in the US. we couldn't take it back to israel cause here it's 50hz and it will damage the motor. check although sometimes it can screw up clocks and things like that. most likely it can, just look at the adaptor.

for example, when i brought my computer to israel, all i had to do was change the switch to 220. just make sure that your adaptor can handle it.

 

[GrantMeThePower]

YES!

you can use it just fine.

In fact, if you look at your ac adaptor it will tell you so.

 

[aircooled]

most modern laptop power adapters will work just fine.

Reading mine now:
"Input: 100/240V 50/60Hz"

 

[So]

Man, it must be confusing to have half your country use 50hz and half use 60.

 

[foofoo]

when you are on the trains from a 50hz to a 60 hz region, the lights go out for about half a second as the train switches to the other electrical gear. it's crazy but their trains have systems for both.

Thank you all for your help.
