Features To Look For In 300 Watt Power Inverters


Yes. The wattage will tell and determine what types of electric appliances you can charge. The more wattage your unit has, the more the Power it generates.

Mostly, this will depend on your use. If you intend to power a few low wattage electronics, then an inverter with 150-300 watts will suffice.

Before you jump into buying decision, determine the watts you’ll need. On the hand, if you intend to spend much of your time in your car or camps, then an inverter with more than 300 watts will provide enough Power to large appliances.

Sine Waves

Most of these models feature sine waves, and these are either pure sine or modified waves. Remember that most electronics are susceptible to damages by irregular waveforms such as jagged square waveforms. While modified sine waves put less stress on devices, pure sine waves are more efficient.

Number Of Outlets

The number of AC outlets and USB ports is paramount. Look for a model that can provide fast charging to several devices at the same time. Maybe you can power your laptop, phone and play TVs at the same time.

Most power inverters come with two standards USB ports and AC outlets. The more the number of outlets it has, the more the wattage the unit must generate. This translates into an expensive inverter.


If you aim is to get a power inverter that offers heavy-duty performance to the elements, consider a durable device that is inbuilt with aluminium.

The aluminium housing tips it to stay longer and stand up to the job. If still feel less secure, opt for a unit with a warranty. This ensures even more protection.


Safety considerations can’t be ignored. Give priority to models marked with ETL stamp. Simply, this means that this product meets all the requirements and all N.

American safety guidelines. This product is safe from overheating, shorts, overloading and other electrical faults.

Frequently Asked Questions – Buyer’s Guide
