I had my second power supply die on me recently, and the only 1000mA 12V's in the area are at radioshack for $20. However, when I called the man said they only had 1500mA ones but that should be fine, as long as the voltage is enough. Having a 1500mA 13.5V one around, I remembered that the car adapter was 14V, so rather than paying $20 for a $5 power supply I decided to test mine and it seems to work just fine (although noticeably hotter).
However, is this just as safe 1500mA adapter, or a 1000mA one for that matter? I know it says on the PD site to use a 1000mA 12V DC (although my original was AC) so I just want to make sure I'm not damaging mine - well, my brother's, mine's in for repairs, but just the same.
