Universal AC to DC Car Cigarette Lighter Socket Adapter

:@ This plugs into the 110 outlet? Not an expert or an electrician. However, from experience, the 12 volt outlets usually are fused and wired for low amps. Many devices will not work on the cigarette lighter. You need to wire the 12 volt plug directly to the battery with heavier wire and heavier fuse. The pictured 110 to 12 volt adaptor likewise offers a low amp output. Depends on what you want to run. There are many 12v to 110 inverters available offering the ability to run heavier loads.
