PSP Power through USB

[zeroboo]

just found a usb power cord which came with my Asus wireless AP WL-330g.

I plugged the other end into my psp and it fits perfectly!!

so now im wondering whether i cld use that to charge my psp?

the stepdown on my psp charger says: output:5V 2A
and the input on my Asus wireless says: 4V 1A

its a bit lower on pawer, wld it work?

You cant USB charge a PSP

P-A are selling a PSP USB charger lead

[g-funk]

your both right in a way, you cant charge it with a normal USB lead, the one from PA attaches to the PSP's power socket.

Yeah sorry, I wasnt very specific. The USB port doesnt accept power to allow a charge was what I was getting at.

I bought one of those USB charger cables from Play Asia today actually, and wondered the same thing. Is there any way such a cable could overload a PSP and/or damage the battery?

For instance, at work I have four USB ports on the front of my Sony monitor, but I'm not sure if the current/voltage coming out of those would be the same as, say, the ones on the back of my keyboard at home.

I highly doubt it would cause any damage, but I'm still not 100% sure. Is anybody else using one of these cables to charge their PSP, or just run it from 'mains'...?

It'll barely charge it at all, tbh. I think USB outputs about 3.5volts? Only good for a top up, if that...

Does anyone know if the USB charger that comes with SPV C500 phones is suitable for charging Japanese PSPs? Would rather ask before trying mine...

[musashi]

Well, mine seems to be working. The pigeon English on the box says it should take 3 hours to fully charge, so we will see...

USB hosts provide a well regulated 5.0VDC, which is exactly what the PSP DC in port requires (according to the English PDF manual I have seen).

Strictly speaking a USB compliant device shouldn't try to pull more than a very few mA though, until it has negotiated with the host... the simple cable is not going to do that, but it really shouldn't pose a problem unless you are running a lot of other power-hungry USB devices from the same host.
