| I was slumming at Radio Shack the other day, and came across a power supply meant for laptop computers and the like. I saw two versions: both are 12V in (auto power), one has outputs from 9V to 24V, the other has 12V to 28V. Both are good for 5 amps. Probably contain switching supplies. Price was $59, I think. I haven't tried either one, but they seem like the ticket for running the I-Opener while mobile. | |
