laptop external hard drive question
I'm using a thinkpad 390e as my pc. Its currently running off an inverter and working pretty good. Now I want to add an external hard-drive and an external dvd rom. My question is about powering the hard drive and the usb dvd player. The self powered ( usb powered ) drives are more expensive so I would like to buy an external hard-drive, which would mean that i would need to power it somehow. From what i've read so far, the inverter alone won't be able to do it ( or will it ? ). What are my other options to power the external units...I'm already splitting my cig adapter to run the lilliput and the inverter.
