If you use a 300-watt power inverter, your battery is going to drain approximately twice as fast as it would if you were using a 150-watt power inverter. Higher wattage drains the battery faster. A 10,000-watt inverter is very expensive. Keep these tips in mind when shopping.Ī power inverter with a higher wattage costs more. You may be wondering if it would be to your advantage to buy a high-wattage power inverter. There isn’t enough output to power that number of devices. There's no point in having four AC sockets on a 150-watt inverter. It's vital you have enough connectivity for your demands, but it must be balanced with your power requirements. That can make a big difference in charging times. On more powerful models, it can be greater than two amps. On cheaper power inverters, the supply to USB ports can be as low as one amp. High-power inverters might have four AC sockets and four USB ports. Low-power inverters typically have a single AC (household) socket and one or two USB ports. Output: Output is measured in watts, and on inverters, it runs from about 150 watts to a maximum of 10,000 watts.Ĭonnectivity: All the power in the world won’t do you any good if you can't plug in your devices. There are two main factors to consider when choosing a power inverter: output and connectivity. If you're going camping and looking for peace and quiet, a power inverter beats a generator every time! A portable generator, even a small one, must stay outside. But you must fill it with gas and run a motor, which can be noisy. Your vehicle will recharge its battery after a while.Ī portable generator creates its own electricity. Most have an alarm that warns you when the battery is getting low or an automatic sensor that detects low power and shuts things down. Left unattended, some power inverters can drain the battery. You keep the power inverter right in the vehicle with you. It takes the battery's DC output and changes it to AC. There is a limit to the power they can provide.Ī power inverter doesn't generate electricity. portable generatorĪlthough larger inverters do exist, this article focuses on 12-volt power inverters that work off of 12-volt batteries. But in general, if the device is light enough to carry around, then you can run it from your vehicle with a power inverter. Yes, there are limits on the amount of power an inverter can provide. Buy one small box that plugs into your cigarette lighter socket or attaches directly to your battery, and you can plug in all those devices and charge your smartphone, run power tools, or set up lights at your campsite. That’s where the power inverter comes in.Ī power inverter has one job: to convert DC to AC. But the vehicle battery is direct current (DC), and all those devices run off of alternating current (AC). That’s because each of these vehicles has a battery (usually 12 volts) that is useful for running a laptop, DVD player, or even a refrigerator. Who needs a power inverter?Īnyone on the move – in a car, truck, RV, or motorboat – can take advantage of a power inverter. Only when you plug in the inverter does it change to AC power. Your cigarette lighter port is also a DC port.
