A generator is now one of the most important things for a home to have. It gives us power when we need it the most.

But the generator doesn’t always give the same amount of power. It sometimes changes, which is bad for the appliances that are plugged into the generator. Because of these changes in power, power surges or drops can happen, which can damage the circuitry of sensitive electronics.

So, how do we make a generator safe for electronics and keep sensitive electronics safe while still getting power from it? The most important thing a generator needs to do to be safe for electronics is to provide clean and uninterrupted power. This is especially important for your more expensive and sensitive electronics, like your cell phone and laptop.

Our recommendation: first step toward making a generator safe for electronics, you should use an inverter generator that makes clean energy to cut down on power surges. Even if you have an inverter generator, you can add a surge protector and an uninterruptible power supply (UPS) to make it even safer and stop power surges from doing damage.

How to Make Generator Safe for Electronics?

1. Use an Inverter Generator

Inverter generators are a good place to start when trying to make a generator safe for electronic devices. With an inverter generator, the speed of your appliances can be controlled by a separate cylinder from the motor.

The term “clean electricity” derives its meaning from the fact that the power generated by an inverter generator is always the same.

Using unclean electricity, which could generate a spike or surge that overloads this delicate equipment, can destroy most modern appliances, especially those that employ micro and nanochips or have sensitive circuits.

So, an inverter generator regulates power production and speed in order to prevent power surges or spiking of the voltage.

If you allow the generator run out of fuel or overload it with too many appliances, even an inverter generator will not provide complete protection against power surges.

It’s critical to have additional backups for your equipment if you want to keep them safe.

2. Surge Protector

Surge protector strips, despite their low price, are an excellent way to safeguard your pricey electronics against damage caused by spikes in the electrical current. If you’re looking to plug many devices into the same power source, a surge protector strip is a good choice.

Despite their similar appearance, a surge strip and a power pack are two distinct products. Surge strips are similar to power strips in that they may connect several electronic devices, but the main distinction is that a surge strip protects your sensitive electronic equipment from surges and other power fluctuations.

For further protection against power surges caused by an overloaded generator, surge strips can be attached to the generator and then linked to your more sensitive, low-output devices.

Laptops, PCs, mobile phones, and other sensitive devices should be protected by a surge protector when using a generator, as these devices were originally designed for use with home computers.

3. Uninterruptable Power Supply (UPS)

Another option to control the power supply to your electrical gadgets is to use an uninterruptible power supply. During power outages or surges, a UPS’s backup battery provides a clean power source.

The UPS is an additional line of defense against an unreliable power supply, but it is only a temporary fix and does not provide a long-term power source. When using a UPS, it is important to confirm the product compatibility of the generator you intend to use.

4. Pure Sine Wave Inverter-Charger and Some Batteries

As an alternative, you might acquire a pure sine wave inverter-charger as your power source for electrical devices. To protect sensitive electronic equipment from damage, this is a type of inverter. Power is cleaned out and transformed into a clean sine wave without harmonic distortion by these handy gadgets.

While your electrical devices will be powered by the inverter, the charger will use generator power to recharge the batteries.

5. Use a Surge Arrester

Surge arrester protects the home from power spikes caused by a variety of different power sources. These gadgets are made to absorb at least 90% of a power spike. That’s all you need to keep your electrical appliances safe. Another ten percent of the power surge is projected to be absorbed by power arrestors that are already a part of the electrical circuit or devices.

Keep in mind that the power arrestors will eventually fail. As a result, they lose some of their ability to absorb energy. Surge protectors of the most recent generation alert the user when the amount of protection is dwindling. Although some arrestors lack this feature, the damage has already been done by the time the users learn they aren’t working properly. Because of this, we recommend that homeowners change their surge protectors on a regular basis.

Massive protection necessitates the deployment of surge arresters. They are a high-capacity gadget designed to withstand massive power surges. As a result, they are somewhat pricey. For those on a tight budget, we recommend purchasing power protectors.

6. Using a Power Line Conditioner

It is possible to utilize power line conditioners to keep electronics operational when running on generator power. It is the goal of these gadgets to lessen the disturbances in electrical current. Therefore, especially when using power from open line generators, these devices ensure that the electricity supply is consistent.

These tools are effective at lowering input power noises like RF interference, EMI, power surges, and so on. A power line conditioner is an excellent choice if you want to safeguard your generator and provide clean power to your electronics. 

7. Use Automatic Voltage Regulator

To maintain a consistent and clean voltage, electronic voltage regulators have been employed in a wide range of devices, including automobiles, for many years. During load changes, they will monitor the generator’s output voltage and adjust the field current correspondingly.

If you want your generator to work properly, you need to invest in a robust voltage regulator. A surge suppressor can be added to the mix. 

8. Other Things You Can Do

Keep Them Dry

Without saying, water is a known short-circuiting agent. Therefore, to avoid this, make sure the machine is kept dry. Dry off the surface of the generator. Keep your damp hands away from it. Move your portable generator to a dry location if you need to use it during the rainy season.

It’s also not a good idea to set up a portable generator inside. It should be kept in a spot that is free of dust and debris, but you can put it wherever you like. Its regular operation can be disrupted by the presence of moisture or humidity.

Additionally, make sure that neither liquids nor oil have made their way into the generator’s inner workings. When throwing a party, keep the revelry away from the power plant’s generator. Power surges are a real risk if liquids get into the workings of the generator.

Disconnect Generator from The Main Power

Many people skip this step, but it’s essential if you want your delicate electronics to last. Power from a generator might potentially cause damage to utility lines if it is not disconnected from the main power source when the power goes off.

Use Good Extension Cords

Heavy grade extension cords are a necessary for reliable power supply and efficient power management. Specific fuse is included in these high-tech cords, and they allow them to withstand power surges. It is important to verify the generator’s wattage before attaching the heavy-duty wiring.

Keep Enough Fuel

The other critical consideration when employing generators to power electronics is to keep a steady supply of fuel available. Having a good stock of fuel prevents an unexpected shutdown of the electrical grid. Make sure to clean and check the generator’s many moving parts on a regular basis.


As you can see, there are several precautions that should be taken to ensure the safety of your electronics when utilizing a generator, especially when dealing with the more delicate electrical components that are part of today’s technology.

An inverter generator is the best option for protecting your devices when using a generator because it produces clean, stable power.

Electronics should be safe when used with a generator so long as you take the necessary precautions, which include using a surge protector strip and uninterruptible power supply (UPS) to shield them from power fluctuations and faults.
