    Does it really have two outputs?

    So for my tv speaker, I ordered an amp from MCM Electronics
    http://www.mcmelectronics.com/product/28-6400
    Provides 3.5W RMS output into a 4ohm load
    Daytton Ohio, and it came in only 2 days to Baltimore.

    It needs a power supply so I was looking f through my box of
    transformer-DC supplies and even though this is too small for the amp,
    I have a question about a WC-4 Battery Charger 404743-000

    On it, it lists its input as 120VAC 5w

    BUT it lists TWO outputs
    10.1 VDC 12mA max
    3,0 VDC 150mA max.

    The output is the pair of male and female snaps one finds on a small 9
    votl battery. AND no other output.

    So why are there specs, on the thing itself, for TWO ouputs?

    Thanks.


    P.S.
    The ebay listings below say it's for charging a 9V nicad battery.
    You can take my word for that, or if you want, check :)

    The WC4 charger is convenient and light, able to plug into any
    standard home outlet and charge any NiCD 9V size battery.

    Okay. Makes sense. I just never saw anything listed like this
    before.

    So when the battery one is charging is very much discharged, it will
    still probably have 6 volts, and 3 volts won't be enough to charge it
    at all I guess
    Maybe I paid 50 cents for it, and I liked it because it was different
    from the others, with the 9v snaps. . I don't have any rechargable
    9votl batteries yet
    I should never have mentioned the amp.

    I have to find a plug and a jack (much harder no that as yet
    unprocessed junk is piled up against the drawers where that stuff is
    kept.). But I'll get back to you all in a few days

    And I have to read t he TV manual more carefullly, since it has more
    than output for the sound (an RCA jack and an earphone jack.) I've
    only had the use of an earphone jack in t he past.
    Thanks.

    The second output shows the voltage at the maximum current out. The first shows
    the current available as the voltage rises to 10.1V when the battery is charged.

    Thanks. It's sinking in.
