Looks like this could work - but not a lot of power.http://cgi.ebay.com/Classic-car-6V-12V-voltage-converter-power-power-/350436684000?pt=BI_Electrical_Equipment_Tools&hash=item5197a770e0#ht_1268wt_1398

This could do it too, but is an install - I see that the minimum input voltage is 6.3 volts which is cutting it close.http://cgi.ebay.com/6-12-VOLT-CONVERTER-RUN-12V-RADIO-6V-CAR-SR6138V-/260833854527?pt=LH_DefaultDomain_3&hash=item3cbae8c43f#ht_931wt_1398

The reason I made mine is that I am only looking to charge a phone or use a GPS. It cost me about $8 in parts. - and it seems odd to me to convert 6 to 12 so that you can convert it back down to 5v. If you have a device that needs 12v (like a radio) that's another story - but they usually need a bit of power, like the second link above.
