psp has its processor speed capped at 222mhz but it is able to go to 33mhz but that will need a lot more power

not only that, but as opposed to a n64 which requries voltage regulators, or independant battery systems the psp virtually all runs on super effiecient low amp converters for its circuits...., plus i the psp has power regulation similar to a laptop, which neither the ps1 screen, voltage regulators. or n64 has

i was wondering if smoething like this could be used to tell how much power is in my battery pack http://www.dse.com.au/cgi-bin/dse.store ... View/Q1457

well, i suppose by power you probably meant voltage and not wattage, either way, what i did on my last portable was i found a old car battery jump box, that had a small 12v battery tester (the old needle kind) and was gonna use that on it, before that unit went up in flames, there is no real way to test power of a battery, since wattage is energy consumed over time and is the product of volts * amps = watts(power), id suggest a cheap 5 dollar digital voltmeter that stays on all the time, they can be found at places like harbor freight..., or ebay perhaps.. since they are such low draw for amperage, maybe .010 amps, they can be tied for power right into your main power circuit onboard your portable...

I hope that helps some
