It is not a pure sine wave

I would recommend this inverter to anyone who don't need pure sine electric to run their sensitive electronic equipment.

but isn't a pure sine

Even though it is not a pure sine inverter, it ran my 32" tv, 5-18 watt lights and power drill with no problem.

I returned it for a "pure" sine wave one

I offer the caution that this is not a pure sine inverter.

After building the 200 Watt power system with success and doing further research it appears pure sine wave would be worth the extra dollars.

Some appliances may need a pure sine wave and this is not but is ok for lights, drills
