Re Powering your COMPUTER with a Battery in the field: Does anyone have a ballpark estimate of what % energy you lose by using an inverter to go from a 12 V DC battery to 110 V A/C if your Computer (Mac) needs A/C to run, and cannot run on 12 V DC directly?

Also, any suggestions re an EFFICIENT, QUIET (rfi-wise), Inverter?

Any estimates/ideas/suggestions appreciated!
Thanks- Peter K6PAA

Even though the Mac has a high-efficiency switching power supply, you can usually figure on losing 30% in the 12VDC-to-120VAC inverter, plus voltage drops in your 12V power cabling, and DON'T use a lighter plug for the source connection.
