A power inverter is a device that converts DC (direct current) power to AC (alternating current) power. Power inverters are used to run AC devices from DC sources such as batteries or solar panels.
Consumer Reports has reviewed power inverters and has found that they vary widely in terms of quality and performance. When choosing a power inverter, it is important to consider the following factors:
– The inverter’s power rating: This is the maximum amount of power that the inverter can provide. It is important to choose an inverter that can provide enough power to run all of the devices that you want to use.
– The inverter’s efficiency: This is the percentage of DC power that is converted to AC power. A higher efficiency means less power is lost in the conversion process.
– The inverter’s waveform: This is the shape of the AC power that the inverter produces. A pure sine wave inverter will produce power that is the same as the power from your home’s electrical outlet. A modified sine wave inverter will produce power that is “cleaner” than a pure sine wave inverter, but not as clean as the power from your home’s electrical outlet.
– The inverter’s features: Some inverters have features that can be useful, such as a built-in battery charger, an AC outlet, or a USB port.
When choosing a power inverter, it is important to read reviews to see how the inverter performs in real-world use. Consumer Reports is a good source for reviews of power inverters.
