Inverters & Laptops
Sea Jay wrote: Better to use a step up DC transformer - much more efficient and compact!! Hmm. The DC-DC converter b393capt mentioned above is rated 88% efficient; a typical boat inverter is nearer 95% efficient when running a smallish load like a laptop. When the wall wart inefficiency is included, they are comparable, the DC-DC converter is not "much more efficient." |
