Hi guys .. I hope you are all enjoying your N900's

Anyways, I had a question about the charger that comes with the US N900 Pack. Is the charger compatible with 220v, which is used in Europe, etc .. (fyi, US uses 110v)

The above can be easily determined by simply looking at the charger and seeing what is written on it. For example, here is a picture from my N73's charger:



Notice that it says that the accepted voltage input is 110v to 240v. I just need to know if the same is true for the wall charger that comes with the N900. If possible, I would prefer if someone can post a picture of the N900 like the one I've posted above. It would really put me at ease

I need to know this because I would soon be going into the 220v region of the world for the holidays and need to know if my N900 (which I should have soon hopefully) would need any converters or not.

From my experience, it'll get fried.

Plugged my PS2 US version into European power socket => a bop sound and smoked it up.

Although if I remember correct, there wasn't any transformer with the PS2 cable, it was direct.

I doubt there's a transformer in the N900 chargers.

PS2 is a different case .. Transformers for relatively more power hungry devices are not so cheap, which is why the manufacturers often leave out the transformers from their power portion .. I dont specifically for the PS2, but I heavily looked into this very issue when I was buying my first PS3 .. PS3 also doesn't have a converter in it (although the early models did)

however, for small devices such as mobiles, making a small transformer is very cheap, and so nearly all mobile phone chargers are voltage universal ..

Are you sure it says 50-80 Hz .. !? afaik, only 50hz and 60hz standards are followed, be it anywhere in the world ..

Not quite.

Of course there is a transformer in there. Your N900 cannot handle 100V or 240V for that matter If there wasnīt a transformer in there you wouldnīt be getting a adapter but just a cord with a prong on one end and a micro usb socket on the other. The N900 takes in 5-9V, which is why you can plug it into your computer and itīll charge.

Always check your chargers before plugging in, but yes Nokia ships universal voltage chargers with their devices and have for the last 3-4 years at least. 110-240V, is fine for the charger.

Was that trip abroad your first one venom?

That must have hurt a little inside to see it go puff!

Not quite. From the current trend in these things, and from the weight of the charger, I'd say that the N900 charger brick is a switching power supply. There's no transformer in there.

On further reading, these may have a transformer in there for isolation from the mains. It's a much lighter transformer that operates at tens of kHz, not at mains frequency. It's a different beast than the old-style iron-core transformer types.
