That would be ideal. However, I've lost the DC charger for my phone, and don't have one for the laptop or the AA batteries. The reason for getting the inverter was to save a few bucks and plug this stuff in with the existing wall warts. > It didn't work all that well for what I wanted to use it for, but I expect > that was because I couldn't get a true 12v DC from a HMMWV (24v system the > Army wouldn't let me modify to add a 12v power plug outlet - they've since > developed a kit to do just that.) > > So really, everything you've mentioned should already run off of 12v DC, > and you wouldn't need the inverter. > > The biggest problem I've had running accessories off the lighter/power > sockets is how the circuit is fused. > > If the sockets are individually fused, you should be ok, although it's > probably fused at 5A. The dash socket only provides power when the vehicle is on. The other three, 2 in the console and 1 in the rear, will provide power even if we shut the vehicle off. So I'm guessing there are at least 2 circuits. I'll check the fuse panel this weekend. > But if they're all on the same circuit, I think you're going to be blowing > a lot of fuses, especially if you try to run them all at the same time off > the inverter, which is going to suck some current for itself in addition to > what it draws to power your accessories. I doubt I'd ever run all 3 at the same time. Fuses most likely wouldn't be an issue. Typically, we only have my wife's phone plugged in up front. Thanks for the advice, John.
