cit200 power adaptor - multi voltage?

    Is anyone able to tell me if the power charger/adaptor for the Cit200 is multi voltage compatible? I ask because I live in Australia, but travel frequently to the states - prices are obviously much cheaper there, but if the charger is only 120 volt, saving $50 buying one in the US isn't much good to me.

    If someone is able to tell me if the charger supports 120-240V/50-60Hz, then I'll be able to order one asap. (I realise the socket pins are different, but a $5 adaptor can cover that).

    Thanks in advance for your help.

    Check on the adaptor for what it's written on "Input". If it says 100-240" or something similar, it means it will accept anything between 100 and 240 volts. If it says only 110 or 120, then you'l need a transformer from 110 to 240. Probably the frequency (50 / 60 Hz) won't affect.
    If you can post a picture of the label on the power supply I can tell you what you need.

    Thanks for your offer of help - that's what I was hoping somebody would be able to tell me - I don't have one as yet, but if someone is able to confirm that they are supplied with 120-240V/50-60Hz capable power adaptors, I'll be buying several of them - for myself, friends & family.

    Anyone out there able to fill me in on the details...? Or even some decent photos of the adaptor so I can try to read the text...?

    I am sure such an information can be clearly seen/obtained from the hardware specs of the device.

    The hardware specifications do not indicate the input voltage of the power adapter. I checked all the documentation and none of it indicates the voltage. The picture on the FCC OET website has too much glare to read the label on the adapter. The CIT-300 is labeled 100-240v 50-60htz, but there is no garantee that the CIT-200 uses the same adapter. Linksys may have omitted the information intentionally, since it may supply different adapters to different parts of the world. I would get on the Linksys support site and do a live chat and may the clueless support personnel may know.

    You may find a picture on e-bay or you may ask any ebay seller.

    Thanks guys - I've already had a look at the information (including downloading & reading ALL of the manual!) , but unfortunately nothing was included with regards to the charger/adaptor.

    I have emailed Linksys to see if they'll provide any information. Otherwise, I guess I'll just have to wait until next time I'm in LA & can get to Best Buys/Circuit City - although I would obviously prefer to find out earlier than that if at all possible.

    I had a look at all the available images through google, but as howardp6 has noted, the flash has made the information unreadable. I have asked a couple of sellers on ebay - hopefully they'll be able to answer the question :clap: Thanks for the suggestion leonardoh

    Guys, thanks for all of your help. From the feedback I have received from a cuple of sellers, it seems as though the US models are only 120V capable, whilst those sold in overseas markets may have the required different voltages - so it looks like howardp6 hit the nail on the head :) I guess I'll be buying it here in Australia then. :thumb:

    I can confirm that the CIT200 power adapter is 120V ONLY (at 150mA, by the way).

    I can also confirm that Linksys is unfortunately not cooperative at all when it comes to getting a replacement for power adapters too.

    If you are able to find a 220V-150mA adapter, you will be able to swap it with little solding. Very easy.

    Well if the connector is standard, you can buy a generic power adapter.
    If the connector is propietary then you can remove the cable and put it in a generic power adapter.
    150 mA is not much, so the adapters are probably cheap.

    leonardoh, the connector is not standard (the cable goes directly into the plastic case of the cradle, where the phone rests while not in use).

    However, it takes only removing three screws, desolding the original cable and solding the new one.
    A 5-10 min. "mod". As I said, quite easy overall.

    Finding a 220v, 150mA adapter is different task though.
  12. leonardoh

    leonardoh Network Guru Member

    150 mA is not the most important information. It can be any value as long as it is higher than 150 mA.
    But it must be EXACTLY the same voltage as the original one (probably something around 5 or 12 volts).
  13. simax

    Output is 9v, 150mA.

    And unfortunately I also thought that anything higher than 150mA at 9v would work. But it is not the case.
    Remember that is a battery charger.

    This is a more technical discussion, but a power source cannot be both a current and voltage regulated source. If it would, then the load would be fixed, which is impossible.

    Probably the charger is inside the phone, and is a different circuit. The current rating of the power source means that you can draw UP TO 150 mA, but you don't have to draw that amount of current all of the time.
    Any electronic circuit uses a different amount of power depending on its requirements in each instant (for example, an audio amplifier can use all of its power when you use it loud, and use little power when you turn down the volume, and the power source remains the same one). The important thing here is that the voltage remains constant (that's why they use voltage regulators, such as the 7809).

    So in conclusion, you can use a 9V 150mA, but you can also use for example 200 mA or anything higher than 150 mA.
    If you are going to build them, you could use 12V power source, with a 7809 power regulator to be safe. If you need help on how to build this, there is plenty of information in the internet, or you can ask me.

    Well, again, all I can say is that I thought so as well but it didn't work

    I used a 9v. 500mA source and it did not charge.

    But it would be great to listen the experience of anyone that gets this to work.

    Have you checked polarity? The wires are not interchangeables.
    Are you sure it didn't charge? If it would be as you are saying, it should have charged faster.

    But I am 100% sure you can use a higher current power source. It is impossible to be in the way you are saying. If it would be giving you 150 mA all the time, and you disconnected the output you'd have current in an open circuit (impossible).

    CIT200 installation files

    Hi Guys,

    I was really happy to see that such a website was existing beside Official Linksys support !
    In fact, we have a CIT200 Skype phone for test purpose, but we didn't received the CD including the installation files. Would any actual user of this model would like to share them with me ?
    this would be very helpful for us, since the drivers are not yet posted on their web/ftp site.

    Thank you in advance,
