What to Look for In a Power Inverter

Wattage

The more wattage an inverter has, the more power it can generate. Depending on your use, you may need large loads of power, or your consumption may be rather minimal. Before you buy a power inverter, consider how you’ll be using the device and try to determine how much power you’ll need. Power inverters can vary widely in wattage, ranging anywhere from 300W to 3,000W and up. Some can even generate surge power as high as 6,000W. 

Number of outlets

Most power inverters have two standard AC outlets for plugging in various electronic devices. Other models offer additional AC outlets and often USB ports as well, to let you charge all the devices you desire—from laptops to fans and flood flights.

Durability

If you’re in need of a power inverter that can stand up to the elements, look for a durable device with features like aluminum casing. Many inverters also have extra protection features to prevent overvoltage or overloaded devices. Still not feeling secure? Opt for an inverter with a warranty for even more protection.
