Which Devices Can Work Fine with a Modified Sine Wave Inverter?
The list of electronics that usually work just fine with a modified sine wave is far too long to get into here. Suffice it to say that if it doesn’t use an AC motor, isn’t a delicate piece of medical equipment, and doesn't fit into any of the other no-go scenarios, you’re probably going to be in the clear.
If the device that you want to power uses a rectifier to change the AC into DC, it’s extremely unlikely that you’ll have any issues. That means your laptop is probably going to be fine, although some manufacturers claim that not using a pure sine wave inverter will shorten the operational lifespan of the laptop power brick.
If the device you want to power up runs on DC power in the first place, like a laptop, you're actually better off looking for a way to skip the transition from DC to AC and back to DC. If that seems complicated, it may be easier to think of it in terms of your cell phone.
When you charge your phone in your car, you don't wire in an inverter and plug in your wall charger. You plug directly into your car's cigarette lighter socket, which is both easier and more efficient. Laptops and many other devices can also be powered directly from a DC power source in exactly this same way with the right adapter.
There are only two types of electronics that you need to be concerned about when using a modified sine wave inverter: appliances that use AC motors and certain classes of delicate medical equipment.
If your electronics don’t fall into either of those two categories, then it's extremely unlikely that a modified sine wave inverter will do any damage. While a pure sine wave inverter is safe for use with a wider range of devices, the greater cost associated with pure sine wave inverters isn't always worth it.
