Why You Want to Use a Pure Sine Wave Inverter Instead of a Walmart Inverter!

Описание: Whenever the power goes out for a long time, people want to be able to use their computers, coffee makers, small refrigerators, etc. off of battery power and they turn to power inverters. These nifty pieces of equipment are available all over the place — Walmart, truck stops, auto parts stores, and elsewhere. But, is it a good idea to use one of these inexpensive power inverters with your electronics?

Nine year-old Grace (KM4TXT) has spent the last two years experimenting with solar and battery power and she recently acquired a Samlex Power 300 watt Pure Sine Wave Inverter. She and Daddy decided to get out the oscilloscope to take a look at the waveforms that come out of a cheap Walmart inverter, compared to the Samlex PSW inverter.

Take a look to see what they found out!
