As stated before, pure sine inverters can be a bit on the pricey side. This tiny inverter costs $99, and that is without any applicable battery. A Ryobi 40V 4.0 Ah battery costs about $149.

The CSI 500-2XD3-IP66 high frequency PWM inverters deliver 500 VA with pure sine wave output voltage. They provide 115 Vac continuous at 60 Hz or 400 Hz, or 230 Vac continuous at 50 Hz.

The CSI 500-FX and CSI 500F-FXW series of compact, industrial quality dc/ac inverters from Absopulse deliver 500VA pure sine wave output voltage.

The new Eaton Pure Sine Wave Inverter produces either 1000 or 1800 Watts of AC power output from a standard Class 8 DC vehicle battery and can be used to power phone chargers, […] Trucks Business ...
