When shopping for a power inverter, you may come across different types of inverters advertised as “pure sine wave” or “modified sine wave.” But what’s the difference? And does it matter which one you choose?
A pure sine wave power inverter creates an alternating current that is exactly the same as the current you get from your utility company.
A modified sine wave inverter is a cheaper inverter that creates an alternating current that is close to, but not exactly the same as, utility current.
So, does it matter which type of inverter you choose? It depends. If you are just using the inverter to power some small electronics, like a phone charger or a laptop, then a modified sine wave inverter will probably work just fine.
However, if you are powering something that is sensitive to power quality, like a medical device or a power tool, then you will want to use a pure sine wave power inverter.
