What Is The Difference Between A Generator And An Inverter Generator

Generators have been around for a while now, allowing travelers to keep some modern appliances going out on the road. The idea is fairly simple.  

An alternator is powered by a gas or propane engine, producing the electricity needed to run electrical appliances. Traditional generators are capable of producing electricity with one hitch; they cannot produce clean energy.

Many modern appliances, especially sensitive electronics like computers, can be damaged by power dips and spikes that often occur with generated electricity.  

This is where an inverter generator comes into play, and since you might want to take it with you to the outback, you should look for a portable one.  

An inverter will produce alternating current (AC) power, convert it to direct current (DC), and then turn it into electricity that is “clean.”  

Clean energy is stable and will not damage precious devices.

What follows is a closer look at the best 8 inverter generators, each with its own advantages and limitations.

Review Of Pulsar PG2000iS

Generator Measurements:  19.7 x 11.2 x 17.9 inches, 47.1 pounds.

Pulsar’s 80cc engine is a single cylinder OHV four-stroke that is cooled with forced air. The 1.18-gallon fuel storage provides 4 hours of run time at rated loads or 8 hours at half load.

It generates 1600 watts at normal load with a maximum of 2000 watts.  It generates 13.3 amps at 120 volts.

Accidental overloading is preventable with the overload warning and shut down of the outlet in question. This a good safety feature in the event a heavy duty appliance is connected to it.

At half load or less, this unit can generate power for a long time. Along with two household-style plugs, it comes with a 12-volt car lighter style outlet as well.

Noise levels average at about 59 decibels.

The warranty on this generator is split. The engine is covered for two years, but the components and labor for only one year.
