WESTMORELAND, Jamaica — An electrical engineer is warning consumers that not all generators are created equal, and many of the smaller, cheaper ones being bought are practically useless for home use.

“Anything under 3000 watts hardly makes sense,” Shavalo Porter told the Jamaica Observer. “If your generator cannot manage even one refrigerator, it’s a waste of money. Trust me.”

While some persons believe a small generator can keep basic items running, the reality is that most appliances, refrigerators, washing machines, and even some water pumps, require significant wattage to operate efficiently. For example, a refrigerator alone may need between 1,200 to 2000 watts at startup. That means a 1000-watt generator will struggle or fail entirely. But this wattage also depends on the specification of the refrigerator.

For those serious about reliable backup power, the recommendation is to purchase a generator rated at 3000 watts or higher.

Prices for these typically range from $120,000 to $180,000, depending on the brand, fuel type, and features.

There are three main types of generators available, Porter explains.

“You have diesel powered, regular gas and [liquefied natural gas] LNG, also known as cooking gas generators,” he said.

Diesel powered is known for durability and efficiency but is often louder; gasoline powered, the more common and easier to source fuel for; while LNG are cleaner but less common.

However, Porter explained that owning a powerful generator is not enough, how you use it matters just as much. One often overlooked hazard is the extension cord, or “drop cord.”

“Many people use small, cheap cords that heat up quickly,” he warned. “That can cause backfeeding or even ignite a fire. Don’t use the thin Chinese extension cords, invest in a durable, heavy-duty one rated for high power.”

As for solar generators, while they sound appealing, they may not be practical during Jamaica’s rainy and stormy seasons.
“The sun hardly comes out during these times,” Porter added. “So what ago charge it?”

For those preparing for hurricane season or prolonged blackouts, the advice is clear, choose a generator that can handle your household’s actual needs, use the right cords, and understand the type of fuel and maintenance required. Cutting corners on power backup can cost far more than the savings you make upfront. Several appliance stores have confirmed that their generator stocks ranging from 1000 watts upwards have been sold old by Friday.

“I could not stand the heat during and after Beryl,” Roxanne McPherson shared, “So I decided wherever I must find the money I will find it. I only need my fan running, my phone and my daughter’s tablet charged. I have tin food so not really concerned about the refrigerator.”
