How To Choose the Right Inverter for your Laptop?
Laptops are expensive and delicate devices. Therefore, choosing the right inverter can either make or break them. The two things you must consider before buying a power inverter for your laptop are your laptop's power requirements and how many devices the inverter can charge simultaneously.
Power Rating:
Make sure that the inverter you’re buying is properly rated for your laptop. The power requirements are printed on your laptop’s manual. Read it carefully and look out for continuous and peak/surge current requirements.
Most laptops draw about 70-90 Watt continuous power. It varies with the laptop’s specifications and the GPU. I recommend purchasing an inverter that exceeds your laptop’s power requirements by at least 20%.
The number of outlets:
Most inverters have two types of AC outlets i.e. plugs and USB. A regular 300 Watt power inverter supports at least two USB outlets and plugs (each). The number of outlets varies with the size of the inverter. A high power inverter can charge more devices at a time.
Pure sine wave vs modified sine wave
There are two kinds of commercial power inverters in the market. Pure sine wave, and modified sine wave. You can use either one for your laptop. The modified sine wave inverter is comparatively cheaper and well-suited for small electronic devices like mobile, laptop, and LED. If you’re planning on using the inverter for more delicate electronic devices (specifically audio equipment) then use the pure sine wave power inverter.
How to use a power inverter with your laptop?
You can use the power inverter by plugging it to a battery. It can be your car battery or a leisure battery in case of people with campervans, RVs, or boats. The power output of the inverter is limited to the fuse size of the car’s power outlet. You can also use the lighter socket to plug the inverter.
Caution: Kill the engine before plugging the power inverter directly to the battery. Make sure that the wires stay away from the radiator fan and the engine when it heats up.
Overusing the power inverter can mess up your car battery. Watch out for the low battery and overload shut-off protection. Your battery might keep charging even after turning the engine off. This will affect both the device and the car battery.
What size inverter do I need to run the laptop?
You don't need a big expensive power inverter for a laptop. A small 300 Watt inverter is a perfect choice for you. A typical laptop consumes up to 100 Watt. The power consumption varies with the laptop size and specifications. Whether your laptop is a regular notebook or a more powerful gaming machine, a 300 Watt inverter is the perfect choice for it. You can even charge your mobile and tablets along with the laptops at the same time.
How much power does a 300 Watt inverter draw?
The formula for calculating the DC power (in Ampere) drawn from the battery is,
Watt (Power) = Volts (Voltage) x Amperes (Current)
Current drawn by a 300 Watt converter is,
300 Watts/110 Volts = 2.727 Amperes.
