Cradle Power Supply Unit

[karmaKid]

Anyone got a link to a cheap PSU which will power the cradle??

Also... what functions/devices will run without powering the unit?

Couldnt you just plug the regular power adapter into the GP2X?

Not to run the cradle, no... and to make matters worse, it needs a 3 amp slupply, much more than your average 'home' muti-way adaptor can provide....

To be fair, it only needs enough juice to run what you are going to shove into it. So just for a simple usb joystick you can probably get away with a 1.2A supply. I'm assuming here they ask for 3A because the 4 USB ports should be able to supply 500mA each (2A), but if you don't have anything sucking that amount of power, you shouldn't need such a beefy PSU.

Of course, this is GPH we are talking about however, so this may not be true...

But if you cant run the cradle with just the GP2X batteries, cant you just run it with a GP2X adapter?

Although the board will run via batteries it is recommended you use a PSU with it since it will be at home anyway, rather uneconomical to waste batteries!


So why can't a GP2X power adapter be used?

For one the cradle runs off 5V and the connector tip is centre positive not negative like the GP2X power adapter.

Cradle needs 5V, GP2X gives out 3.3V.

Yes, but batteries give 3.3V, not 5V, and it runs fine on that

I assume power-light things (mouse/keyboard) will work using a GP2X power adapter (or batteries) then, but higher powered things like Wi-Fi would not.
