    Roadmate 2000 - AC Power Supply?

    I just purchased a Roadmate 2000 GPS unit. There appears to be *no* AC
    adapter/charger included with this unit. Which one would work?

    Any that will provide 12v, nominal, with adequate current, and correct

    That looks like it has a barrel type tip on it, if the polarity markings
    are visible on the receiver or can be determined from the DC power cord,
    I would try any good quality 12 Volt (nominal) AC adapter that was
    polarized right and fit.

    The power specs say that has a 1200mA battery, so the AC adapter should
    be rated for 1.5 or 2 Amps or so to allow for charging a low battery.

    The internal Li-Ion battery is probably a 3.7V or 7.2V battery. So it
    appears that the RoadMate will take power from a nominal 12 VDC source
    (automobiles typically have up to 14V or so with the engine running or a
    fully charged battery) and regulate it internally.

    I recently purchased a Roadmate 2200T, which is similar to the 2000 and also
    does not come with an AC adapter. What I found was that the Magellan 12V
    charger has an output of about 5 volts (I measured it), which is the same
    figure Magellan tech support gave me. Unfortunately, when I tried using an
    AC cell phone charger, it would not fit into the Roadmate socket. For
    whatever reason Magellan's socket is smaller in diameter than a standard low
    voltage minijack. I plan on looking into the possibility of a step down
    adapter that will enable use of a charger with a standard size plug, but
    don't know if it exists.

    Try this link:
    http://www.daydeal.com/product.php?productid=8769&cat=539

    They offer free shipping in the United States. I bought one to use with my
    Lowrance IWAY 100M so that I could enter waypoints I found on my computer.

    Magellan mistakenly included an AC/DC power supply in my Roadmate 2000
    package. Its output is 5V, 2 amps. If I'm reading the Roadmate legend
    correctly the tip of the charger plug should be positive with the
    outside of the "barrel" negative.

    I just *LOVE* when people pretend to know something and spread that around.
    I know you *MEAN* well there Jack, but your off target by a mile.
    First off, the 1200MA rating is NOT the current drain..but the amp-hour
    rating of the battery.
    1200MA/HR means just that..1200MA for 1 hour,600MA for 2 hours,300MA for 4
    hours..understand?
    battery voltage....You will NEVER charge a 7.2 volt battery from a 5 volt
    source. The car adaptor puts out
    5 VOLTS, the 12-24 volts NEVER gets to the Roadmate case.
    3.7 volts IS a common battery voltage for portable devices, and do charge
    very well from 5 volts. 3.7volts is common for cellular
    telephones.

    This means a power supply that put out 5 Volts....that means *FIVE* not 4.5V
    not 6.0V....*FIVE* volts at better than 500MA
    will do the job nicely.Where do you get one? Good question!
    You will find that a 5 volt supply is NOT as common as you would think, but
    not to worry....
    WAL*MART!!! yep..thats right! You will find it among the CAMERA goodies.
    Seems digital cameras like 5 volts.
    WAL*MART has them, about $14 and they are rated at 5.0 volts and will do
    1000MA, run cool and come with assorted
    tips.Just make ***DAMN** sure you position the plug so the tip is POSITIVE.
    Mark it, glue it,wrap it in tape. Do not ever
    connect it backwards.
