    hello you, knowledgable people :)
    i just foudn your forum and it seems really high level of electronics to me ..however it is the only forum that i found that could answer my really easy question.
    so..i ahve a minidisc player whose charger is dead.
    it is 6volt ac/dc adaprot 800ma
    i found that really cheap ac/dc unregulated adaptor which runs form 3vto 12v but is only 300ma..
    before opening it i want to make sure that it could be suitbale for my player.
    i am hoping so as it was much cheaper than the other one if found.. :p,,can anybody tell me if
    1) that will work
    2) it will work but with time might damage my player 9i dont think i wil be using that adaptor more than ten times)
    3) i can rush tot he shop and get a refund because there is no way it can work

    thank you in advance

    Yes, assuming it has a 6V output it will work.

    The original charger had a capacity of 800mA because it was a charger.

    To run the player, without charging, 300mA will be sufficient.

    well i am not sure i made myself clear
    the player runs on a rechargeable (lithium??) battery and i was using the ac/dc adaptor that came wiht it to "charge " it...
    now, are you telling me that the only way the adaptor will play would be if it is plugged int he main.. and that the adaptor i bought, the 300mA, will not actually "charge" the battery so i can use my player wihtout having it plugged?
    thanks for your answer.

    sry but there is no really easy way to make a charger to charge batteries without something being plugged in :(... If that was the case we would never have disposable batteries lol :lol:

    I think that as the original charger could deliver 800mA there is a chance that the 300mA one wouldn't satisfactorily operate the player and charge the battery. Or at least it would take a lot longer for the battery to get fully charged.

    The manufacturer would almost certainly not have provided an 800mA device if a more modest current would have been sufficient.

    It may be sufficient if you have the patience to wait longer for the charging process, but don't be surprised if it isn't.

    I once questioned wether it was ok to use the wrong power supply for a laptop because i noticed someone using a power supply that output 1/5 fewer amps than the original power supply.

    I was told that it was ok it just wouldn't charge the battery as fast especily when the laptop was in use.

    So your adaptor probibly would work I don't believe it would do damage to the device but it would be pretty slow. If it was a little closer to the original amount I'd say go with it for sure but it's quite diffrent.
