Need 8.4v to power new PS2

I currently have the old big version of the PS2 and I use a power inverter to power it. This works fine except it drains my battery rather quickly. Ive been trying to figure out a way to install it in my glove box but it's too big. I have been planning on converting it to 12v, but never got around to it because I wasn't happy with its location.

The release of the new much smaller PS2 ( http://www.us.playstation.com/consoles.aspx?id=3/info/specs_70000.html) has solved the problem of fitting it in my glovebox, but it uses 8.4v instead of 12v.

Is there a way to bring the voltage down to be compatable with the PS2? I've searched for voltage reducers, but I've only found 24v-12v and 12v-6v.

Any input you can give will be appreciated.

Thanks

Would this work?

DC Voltage Reducer

For TVs, stereos, cellular phones, notebook computers and other delicate electronics. Steady output voltage. 1.5-9.6 volts on 12 volt and 5-20 volt on 24 volt model (preset at 12.6 volts). 88% peak efficiency, 0.014 amps idle.  Removes voltage spikes, power surges and ground loops.  Can be used for battery charging. Not recommended with motors.  Not recommended for most phones and answering machines because the phone ground will cause a buzzing sound if this voltage reducer is connected to a battery which is grounded on the negative side.

Good Idea. I'll try it this weekend and let you know. If you can figure out the design and would be willing to make an extra one I'd gladly pay you for the parts and time. I've never really gotten into maikng circuit boards yet.

Anyone use DC power adapter with the new ps2.  I am going to buy one and would seriously be interested in running it directly off DC rather than converting it from DC to AC then back to DC.  The board is external correct, since the new PS2s power supply is external?
