I'm wondering if I can get an external battery source for my Sony Portable Printer. The specs on the power adaptor are:
100V-240V AC 50/60 Hz
24V DC 2.2A
I've seen photographers use an external battery source (not battery grip) for their SLR... it's like a block with wire connecting to SLR. Wonder if that can work with printer too? How much do those cost?
