[apple-iphone] voltage/amperage... and external batteries

sorry for hyjacking the last thread, I forgot to change the
subject line, so I have redone the post.

Patrick, since you do iPhone repair, I am in hopes that you can
help me here. I want to find an external battery supply for my
iPhone 3GS but the ones that I have been looking at have had
numbers that have left some questions for me, mostly like, will
this over or underpower my phone. Apple will not tell me what
the minimum and maximum Voltages or Amperages are for the 3GS, so
I have been googeling and finding very little. Since all of these
batteries are based on USB that puts them at 5 volts or just a tad
higher none that I have seen are over 5.3 volts. But then the
next bit of info says
This is an IMP500 to see more go to
<http://cgi.ebay.com/New-3G-3Gs-IPHONE-EXTERNAL-BATTERY-Black-IMP500-5000mAh-/350345037157?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item5192310565#ht_4542wt_1165>
- Nominal input: DC 5.0V/1,000 mA
- Nominal output: DC 5.0V/600 mA
- Capacity: 5,000 mAh/3.7V

The CP506 will say:
Output Voltage: DC 5.3V
Output Current: 1A max
Double USB output, each output current: 500mA
<http://cgi.ebay.com/5000mAh-iPhone-BlackBerry-External-Battery-CP506-IMP500-/170463634824?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item27b06ca588#ht_1800wt_939>

This seems to be conflicting info to me since these are both 5000
mAh batteries, and although the numbers are different, so are the
parameters, yet are they both the same? And in addition, will
either one or both hurt my iPhone?
I know that the Mophie is iPhone/Apple approved and I have one,
plus I have two Mili units which are virtually the same as the
Mophie, but these are just not large enough for what I need to do.
I need as Tim Allen would say, "More Power" but I am looking for
an economical way to do it with out hurting my phone. Could you
possibly shed some light on this for me please?
Thank you
Kelly
