300 Watt Power Inverter Reviews

What devices can be powered with a 300 watt power inverter?
 
Getting the right size for your device is important; get it wrong, and you could damage either the inverter or the appliance.

Power inverters are measured in watts, and a 300 watt power inverter is best for car applications and for small home devices, or devices in your car such as your phone.

Today we're going to take a look at some of the best available 300 watt power inverters currently available on the market today.

Since batteries are the normal source of DC power, you’ll need a power inverter wherever you find batteries. The most common use is probably in the car; if you’re trying to find a way to use a wall plug in your vehicle, you’ll need a power inverter.

You might also need one if you use a battery-powered generator at home. Beyond the maximum wattage that can be used with the inverter, other important factors to consider include the outlets on the inverter. Most power inverters make use of standard outlets, perfect for small appliances and gadgets.

Some examples of devices that can be powered off a 300 Watt inverter include include Cell Phones, CD Players, VCRs, Satellite Dishes, Printers, Laptops, MP3 Players, a PS2/Xbox, and a 25” TV.

These devices have ratings from as low as 24 watts, to as high as 175. If you spend a lot of time in vehicles, or want to use lights in emergency situations, then these power inverters are best for you. If you run larger devices, you may need an inverter with a higher wattage rating.

Go Power! GP-SW300-12

Unlike any of the other inverters on this list so far, this power inverter by Go Power is a pure sine wave inverter. SImply put, a pure sine wave inverter provides a steady, smooth stream of power comparable to the power from a supply company. Most inverters provide power in “blocks”: overall, it’s a steady flow of power - but if you broke it down, you’d notice it was actually a bit choppy. For most devices this doesn’t matter much. Nearly any device you’d charge in a car works fine with a modified sine wave inverter, like the previous entries on the list.

But if you’re looking for a power inverter that’s ideal for home use, then this is the one you should get. The pure sine wave ensures a smooth power supply for sensitive electronic devices, like TVs or refrigerators.

On the pricier end, but you're getting a pure sine power inverter that you can trust.

The price point for this inverter is higher than the others on the list so far, due to the pure sine wave output. But for that feature, the price is quite reasonable and the reviews are favorable. Even the yellow color is unusual and a nice change from the more typical black-and-red color schemes.

Leadchuang 300 Watt Power Inverter

Another power inverter worth the purchase is this one by Leadchuang. It has an ampere rating of 8.4 A, and comes with four USB ports and one 110v AC power outlet, making it perfect for charging mobile devices.

Standard price-point for this power range. 

This entry from Leadchuang is one of the most inexpensive on our list. It achieves that honor partly by cutting the number of outlets offered from two, which is the standard for a 300 watt inverter, to one. To make up for the single outlet, it provides four USB ports, clearly designed with a mobile generation in mind.

AIMS Power PWRI30012S Pure Sine Power Inverter

If you are using voltage-sensitive devices that require a pure sine wave input, then this power inverter is perfect for you. It’s one of the most advanced out there, and you can be assured of fine and smooth operations with this 300 watt power inverter.

Very affordable pure sine wave option, from a well known brand. 

Another pure sine wave offering - at a far higher price than the normal car-adaptor type of inverters, this one from AIMS will give you a smooth supply of power for the most sensitive devices. Build quality receives good reviews, and the inverter still weighs under three pounds.
