NRG Ultra-Compact Modified Sine Power Inverter, DC input to AC Output, 140 watt, with Cigarett DC Input.

NRG inverters allow devices designed for operation from 120VAC household current to be operated from 11- to 15 volt DC power sources such as NRG battery packs, automobiles, or RV's. Don't confuse these quality high-efficiency inverters with the lower grade units flooding the market. The 12140 is a modified-sine inverter, while 12150 and 12300 inverters feature True-Sine technology, a feature typically found on far more costly products. True-Sine Technology ensures that the output voltage waveform is the same as that typically obtained from your household outlet. This gives maximum protection and assures proper operation of the connected devices. All units feature overload protection and low-battery shutdown.
