There are many benefits to traveling in an RV – from saving money by avoiding hotels to exploring the great outdoors (while enjoying the comforts of home). But all that can come grinding to a halt if your only power sources are weak and unreliable. Don’t choose between your refrigerator, microwave, or cell phone. Instead, invest in an RV power inverter that can handle it all!
When Purchasing an RV Power Inverter: You should consider how much energy you will need and what items you want to power (see video).
Types of RV Power Inverters: Pure sine and modified sine wave inverters are the most common. Pure inverters produce the kind of power available in your house, will not damage sensitive electronics, and come with a higher price tag. Modified sine inverters are generally less expensive, but may damage sensitive electronics (phones, laptops, etc.) over time.
Important information or terms to know when discussing RV power inverters:
Note: Volts are easier to compare (than watts) because they measure a single factor, while watts measure two.
GFCI Outlet: The outlets in your bathroom that have a test/reset switch to protect electronics
Explanation of the “Conversion” Aspect of RV Power Inverters: There are two types of electric current: Direct Current (DC) and Alternating Current (AC). Inverters take battery-produced DC and convert it into AC, which is used by electronics. The “Voltage Conversion Range” listed with each product below will give you a sense of the input (DC) to the output (AC). For example, many options on the market offer 12V DC (input) → 110~120V AC (output).
Here are our favorite RV power inverters that are easy on your wallet.
