400 Watt Power Inverter Reviews

In this article we will explain exactly what a 400w power inverter is capable of, what its limitations are as well as recommending the very best 400w power inverters for all occasions.

If you ever traveled on a long road trip with your family, you must be aware of how difficult children can be when they are confined to a place. A way to remedy this is to give them a tablet or laptop but the main problem with doing that would be the battery. This is because tablets and laptops can’t run for too long on a single charge.

At this point, a power inverter can be of immense help to charge up your kid’s electronic appliances. The above example is just one of the ways a power inverter can be useful, there are also some other situations where they can be handy such as when you are camping or hiking or on a vacation trip.

The power required for an inverter to run is about 8 to 10 percent than the power load of the appliances being run. This is due largely to the efficiency of the inverters. The easiest way to work out how much DC amps 400 watts inverter will draw is as follow:

Watt(Power) = Volts (Voltage) X Amperes (Current)

Current drawn by a 400W inverter (400/110) A = 3.64 amps

The best way to know how long a car battery will run when using an inverter pulling 400 watts of power is to know the amps hours of the battery you intend to use. For example, a 90-hour amp rating battery should be able to run a 400 watt continuous load for about two hours. The higher the amp hour rating, the longer the battery will last.

It is important to note that a car battery is designed to provide a large amount of current that a car battery is designed to provide a large amount of current over a short period of time and it is typically never drained more than 20% of its total capacity. This means it is not designed to be totally discharged but will wear out very fast.

For your convenience, it is recommended you get a deep cycle battery to provide power as they are designed to provide a steady amount of power for a long period of time.

The amount of power consumed by a laptop depends largely on the screen size, typically they consume as low as 40 watts and up to 100 watts when they are off the battery.

When a laptop is charging, the power consumption of the laptop battery usually increases from 20 to 30 percent. For a 15-inch laptop, an average of 70 watts is consumed when it is plugged in, so a 400 watts power inverter is a good choice to use with a laptop.
