Unlike all the other inverters on this list so far, this inverter from Go Power is a pure sine wave inverter. Simply put, a pure sine wave inverter provides a constant and uniform power flow comparable to that of a utility company. Most inverters deliver power in “blocks” – generally it’s a constant flow of power, but if you break it down you’ll find it’s actually a bit choppy. For most devices, this doesn’t matter much. Almost any device you would charge in a car will work well with a custom sine wave inverter, like the previous entries on the list.
But if you’re looking for an inverter that’s ideal for home use, you’ve got this one. The pure sine wave provides a smooth power supply for sensitive electronic devices such as televisions or refrigerators.
On the pricier side, but you get a pure sine wave inverter you can rely on.
The price of this inverter is higher than the others on the list so far, due to its pure sine wave output. But for that feature, the price is reasonable and the reviews are favorable. Even the yellow color is unusual and a nice change from the more typical black and red color schemes.
