I tried to charge mine from the USB charger that I use with my Blackberry. No Joy.
I was able to charge from my Mac G4 Powerbook.

Charger from Frys

I was out in Denver recently and found a "multi-charger" there. It plugs into a USB on the computer and has an octopus of other connectors at the other end. There are PSP/eReader, mini-usb, iPod (also will sync), gameboy, and a few others. Very handy. Was something like $10. A very handy investment.

What is the power output shown on the PSP charger? I want to make 100% sure that it is the same as the Reader's charger.

It's not exactly the same, but ... well, let me put it this way: when we were at the Blogger's Day thing last September, they were using PSP chargers on some of the Sony Readers they had set up for that, so it would seem that the Sony Reader team believes they PSP chargers are 'close enough.'

Would not close enough possibly cause some damage since it's not the same?

Charging via other USB connections

I have tried other USB connections for charging as well and they drain the Reader's battery rather than charging it. I have several small chargers that are designed to plug into a mini-USB connection to provide charging power. They do not work with the Reader.

If I had tools and parts here I would make a little breakout board to analyze what is happening. I suspect the Reader has a way of enabling the power connection from the USB port to its charging circuit. Why did Sony design the Reader this way? Maybe they are trying to protect the Reader's charging circuitry from non-compliant USB power supplies, though they are all supposed to be standard. Any thoughts?

Thanks to NatCh for the clarification (see next).

I dunno what might happen with other chargers, but I think that the PSP one is fine, on the basis of the Sony team using them.

I probably should point out (since this is nominally a USB charging thread, and there might be some confusion on the point) that the PSP charger won't charge via the USB port, but rather the DC in jack. It think the multi-charger that Plowman found is the only non-Sony USB charger that I've heard of working with the Reader.

Plowman, your charger sources power from USB, but does it plug into the Reader's mini-USB port to charge via USB as well?

I'll also point out that my Reader has charged successfully from the USB port of every Mac I've tried it with. Without installing any Sony software ('cause there isn't any! ).

Yet on a PC the Sony driver must be installed for the USB charging to work.

The PSP charger I have seen is rated at 5.4 V which is within the range (limits) of the Sony Reader charger. I also use the iGo Juice charger which works from the wall outlet, the car adapter, and an airplane power connection.

Is that the same one for the PSP, then? I was assuming I'd just look for that one.

So the Reader accepts a MAC to charge its battery because it's not possible to install Connect on it. But if it is a PC it wants to see the Connect software in order to charge the battery. So who at Sony came with this brilliant idea?
