Hi, anyone still on this post? You say i can use a PSP charger to charge my a Zaurus, is that so?
Its just it says its 2000mAh and the sharp is 1000mAh, i don't want to blow any fuses. Im only cautious as i broke my PSP with experimenting with other chargers.
-Thanks
Sharp also used to sell a 2000mAh charger, if that makes a difference. As far as the amps are concerned a higher rating doesn't matter because, as Deluxe says, amps is a measure of how much the unit draws; the charger will not supply more than the Zaurus draws, so a charger with a higher amperage rating *cannot* damage the Zaurus--as far as the *power* is concerned. A *lower* rating could possibly damage the Zaurus but a higher one cannot.
On the other hand, the charger *will* supply whatever voltage it supplies regardless of what the Zaurus wants, and since the Zaurus voltage seems to unregulated the power supply *has* to be. If the charger varies greatly during its cycle or spikes sharply as the load decreases (as Speculatrix mentioned), then that will almost definitely damage the Zaurus.
So "what matters" is *both* amperage and voltage--as long as the amperage is at least 1000mA and the voltage is regulated at 5 volts you will be fine.
I actually use a psp charger for my Zaurus almost exclusively *because* of the higher amperage rating--when it's plugged into the wall I'm usually running a high-powered wifi card, usb mouse and keyboard, and very often a memory stick of some kind, so I want the insurance for the extra power being used. Just for charging the battery, though, I have a psp cable with usb on one end and the charger plug on the other that stays connected to my computer and is used for both the psp and Zaurus depending on which needs to be charged at the time...
