    because of the higher current rating, it charges your cell phone really quickly! Try it if you have not done so already!

    ...and shortens your battery life most likely in the process.

    it does shorten the battery life. I have been playing with that and it drains as fast as it charges. I wouldn't recommend using the tp charger on your pre unless you have to. I ordered a couple new batteries from Amazon so I figured I'd see what happened. Fast charge and fast drain.

    There's a reason the charger that came with the phone has a specific voltage/amperage and it's not to be exceeded.

    What if you have the touchpad charger plugged into a phone's touchstone? Would that also charge faster and potentially reduce battery life?

    All batteries designed for electronic devices are designed for quick charging usually .30 - 1 hours for 80% charge then complete charge in 2-3 hours, or something similar. What shortens battery life is over charging not quick charging.

    although I would use the charger designed for the phone as it was made specifically to charge the device.

    Whether you use the original Pre charger or the TP charger it will not decrease the charging time for your Pre battery. The TP AC charging device is "capable" of delivering a higher current output, but only if the charging device is capable of drawing the current. The battery just accepts what the charging circuity sends to it. The TP charging circuity draws more current (amperage) from the AC charger which the Pre charger cannot deliver.

    This.

    For voltage, as long as you are within 10% tolerance you're good. Also for current, it's how much the adapter can supply, phone draws as much as it needs.

    The TP adapter is slightly higher in voltage.

    That would make a difference. I was assuming the output voltage of the Pre and TP AC chargers were the same. Anyone know what they are? I guess I could put a voltmeter on them and measure when I get home.

    5.2V I think if memory serves correctly.

    Which goes back to my point about +/- 10% is OK.

    TouchPad charger specs:

    Wall AC to USB power adapter, which has input specifications of 100-240 Volt 50–60*Hz 0.4 Amp AC, and output specifications of 5.3 Volt 2.0 Amp DC. It is cylindrical roughly the size of a "D" battery with a foldable 2-prong AC connector and Standard-A USB socket on its two ends.

    There's the difference.

    .3 volts is not a significant difference. Both voltages are within the tolerance allowed of the other.

    Pretty much what I was getting at, however notice the amps. Pre charger is 1, TouchPad is 2.

    Nope, actually lengthens your battery life by keeping its LIion battery topped off (thats what they like). Want proof? My Pre battery is over 2 years old and has spent 90% of its life on a TS charger either on my night stand/car/office desk and it is still going strong.

    I just needed a couple of extra words to understand why you said 'notice', is that good or bad - why?

    I'm using the touchpad charger to charge my blackberry. I notice a pretty big difference in charging speed and it hasn't reduced my battery life nor make it drain quicker.
