How to Pick the Perfect Portable Semi-Pro Generator

Portable Semi-Professional Generator Buyer's Guide

The great thing about generators is they come in so many sizes, wattages and styles so it's easy to find one that fits just right.

So how do you find your Goldilocks generator?

Well, if you're in search of a "high-end emergency" or a "less-expensive professional" generator, you've struck gold.

Semi-Professional generators are the answer; heavy-duty machines with up-scale features, but without all the bells & whistles found on professional units.

Several semi-pro generators feature GFCI outlets.

A ground fault circuit interrupter, or GFCI, is designed for safer electrical handling. Unlike traditional outlets, which have two wires (neutral & hot), GFCIs have a third, a ground. When the GFCI detects an imbalance of power flow, it automatically cuts off power to the circuit, in as little as 1/30th of a second.

The National Electric Code require GFCI outlets for swimming pool lights, construction sites, bathrooms, outdoor use, unfinished basements, laundry sinks, etc. The common link is electricity and water don't mix, so having GFCIs on your generator is a safer option.

Low-Oil Shutoff

An unlubricated engine is a disaster waiting to happen. All portable semi-pro generators have oil-lubricated engines, but the brainy engineers charged with their design developed a safeguard to prevent a disaster: low-oil shutoff.

Your generator engine can be damaged if it runs without good oil for too long. However, the engines on semi-pro generators will either warn you of a low-level, or shut down when it is detected. This is especially important if you're not near your generator at all times while it's running.

Electric Start

An electric-starter is a nice feature found on some semi-pro generators. It will allow you to turn on your generator by turning a key or pressing a button.

The other option is a recoil-starter where you pull a rope to fire up the generator. The nice thing about electric start generators is if the battery for the starter is dead, you can still start it with the recoil option.

Power Bar

Some models of semi-pro generators feature power bars, alerting you to the power output of the generator. It's essentially like having a built-in wattage meter on your generator.

This is a great feature to have because you can see how much wattage you have left to use. Overloading your generator and tripping a circuit will force you to stop what you're doing and reset the circuit. More importantly, a power overload on the generator could
damage the items you're powering.
