About products and suppliers:

A power inverter changes direct current, or DC, into alternating current, or AC, making a DC-to-AC inverter or solar inverter essential to using alternative power systems. Those store electricity as direct current while home appliances use alternating current. Car batteries power a vehicle with DC, but a power inverter allows car owners to power appliances with a vehicle battery. An RV inverter can provide AC current to appliances when vacationing.

Why Do You Need an Inverter for Car Use?

A power inverter is handy for car owners for several reasons. An inverter for car use provides an outlet in a car or truck for charging cellphones and laptops and running small appliances. A power inverter can make camping more comfortable and can even provide AC current to tools for car repairs. If you have an inverter for car use, you will always have access to AC electricity in emergencies.

Do You Need More Than One Inverter Battery?

A power inverter runs off the power of a 12-volt battery, which is drained as the inverter converts DC current to AC. An inverter battery can be recharged by running a car motor or from alternative energy sources such as wind or solar. Since a power inverter is often used in an emergency situation, it is a good idea to have more than one inverter battery.

What Will a 220v Inverter Run?

A 220v inverter will power appliances such as refrigerators, washing machines and dryers as well as lights and fans but is best for charging phones and computers and lighter uses. A 2,000-watt inverter or a 3,000-watt inverter will need to pull DC electricity from multiple batteries since their power would drain a single battery. If you are using a vehicle’s 12-volt battery to power your home with an inverter, remember that you can only convert as much DC power as your alternator can replenish without completely draining the battery.
