Anyone have any? I have searched the forum up and down since I got my new SL-C1000, and I'm perhaps being a little bit paranoid over this. I know the adapter is not rated for U.S. voltage, but that there is evidence that it can handle it. Also, it seems nobody has ever been able to provide hard evidence (or at least plausible anecdotal evidence) that the EA-72 adapter killed their Zaurus.
Still...should I get a PSP adapter for it instead? Have any of you used the EA-72 for a long time and without problems?
There were several reports of broken C760s and C700s with EA-72 adaptors;
some reported in the forums, some to Trisoft and other vendors.
People who reported bricked Zaurii ultimately found that a SMD resistor had failed in the charging
circuitry on their Zaurus mainboard. They reporting "everything was fine, and then suddenly one day, KAPUT!"
I don't think anyone conclusively figured out what the problem was, but there have been very few
reports of bricked/destroyed Zaurii since.
I'll repost my last, best guess, updated for December 2007:
EA-72 was designed for Japanese power, with slightly lower voltage, and so Sharp got away with using
components with lower tolerances for voltage variation.
In unusual circumstances, (or possibly simply using it for a long long time) something either failed
or momentarily glitched in the EA-72 under US power- frying the Zaurus' resistor.
Since then.... one of two things may have occurred:
either Sharp began using different components in their EA-72s (with higher rating, higher tolerances)
or they changed the charging circuitry within Zaurii to be less sensitive to spikes or glitches from the adaptor.
I guess I'd still recommend using something other than an EA-72 if you can,
but if your EA-72 is new(ish), or your Zaurus is new(ish) you're more likely to be safe.
If the only recent forum posts you're finding, are ones like mine-
even more likely you're safe.
