A 2.5kVA generator can be a valuable power source in various situations, whether you’re dealing with a power outage or need electricity in a remote location. But what exactly can a 2.5kVA generator power? You’ll discover some of its capacities, including some of the equipment the generator can’t power as you read further.
What To Know About 2.5kVA Generator
Before we go into details, it’s essential to understand what “kVA” stands for. “kVA” is an abbreviation for kilovolt-amperes, a unit of apparent power. It is different from kilowatts (kW), which is a unit of real power.
Note that apparent power includes both real power and reactive power. And when it comes to generators, the rating is typically given in kVA, indicating the total power output capacity.
That said, a 2.5kVA generator can provide up to 2.5 kilovolt-amperes of apparent power. However, the actual usable power (in kW) may be slightly less due to the power factor of the connected load. The power factor is a measure of how efficiently electrical power is converted into useful output power.
What a 2.5kVA Generator Can Power
Here are the appliances/equipments a 2.5kVA generator can power:
1. Lights (up to 10 bulbs)
A 2.5kVA (kilo-volt-ampere) generator has a capacity of 2,500 volt-amperes, and it can power multiple lights, including LED (Light Emitting Diode) and CFL (Compact Fluorescent Lamp) bulbs, depending on their individual power ratings and the total load of other connected devices.
Common wattage options for LED bulbs include 5W, 7W, 9W, 12W, and higher. And a standard 60-watt incandescent bulb can be replaced by an LED bulb with a power rating of approximately 8-10 watts while providing similar brightness.
For CFL bulbs, they are more energy-efficient compared to traditional incandescent bulbs. Their common wattage options include 9W, 13W, 18W, and so on.
2. Fans
Also, with a 2.5kVA generator, you can run your fans simultaneously to ensure comfort in hot weather. The power consumption of common fans used in Nigeria is usually within a range that a 2.5kVA generator can handle.
Note that ceiling fans, commonly used in homes, typically have power ratings ranging from 50 watts to 100 watts. Some energy-efficient ceiling fans with LED lights may have slightly higher power consumption, but they still fall within the capacity of a 2.5kVA generator.
As for standing fans, their power consumption can vary based on factors such as speed settings and additional features like oscillation. Notwithstanding, they usually have power ratings in the range of 50 watts to 120 watts.
If you have multiple fans of different types, you can add up their individual power ratings to determine the total power consumption. As long as you don’t go overboard, a 2.5kVA generator can power more than a fan, even when used alongside some other home appliances.
3. Refrigerators (up to 12 cu. ft.)
A 2.5kVA generator is also capable of powering a small refrigerator up to 12 cu ft. If you have the generator, you need not worry about keeping your perishables fresh during a blackout.
Compact single-door refrigerators, commonly used in small households, typically have power ratings in the range of 80 watts to 150 watts. If you use a single-door refrigerator, note that a 2.5kVA generator can easily power this type of refrigerators.
Also, larger double-door refrigerators, suitable for larger households, usually have power ratings ranging from 150 watts to 300 watts. While a 2.5kVA generator can also power most double-door refrigerators, it’s important to check the specific power rating of the model to be sure.
For energy-efficient refrigerators, often labeled with star ratings, they consume less power than standard models. If this is the kind of refrigerator you use, you can be rest assured that a 2.5kVA generator is generally capable of powering energy-efficient refrigerators with star ratings.
4. Television and Entertainment Systems
The power consumption of televisions and entertainment systems can vary based on factors such as screen size, type (LED, LCD, plasma), and additional features. LED and LCD televisions are energy-efficient, and their power consumption generally ranges from 30 watts for smaller screens to 150 watts or more for larger screens.
Thus, a 2.5kVA generator can comfortably power LED/LCD televisions within the common size range for households.
Mind you, plasma televisions, though less common nowadays, tend to have higher power consumption compared to LED/LCD TVs. Their power ratings can range from 100 watts for smaller screens to 300 watts or more for larger screens. That said, while a 2.5kVA generator can generally handle smaller plasma TVs, larger ones may approach the upper limit of the generator’s capacity.
5. Computers and Laptops
A 2.5kVA generator is also capable of powering computers and laptops, enabling you to work or stay connected online while the generator is on. Desktop computers can have varying power requirements depending on their specifications.
On average, a typical desktop computer may consume around 100 watts to 300 watts. In that case, a 2.5kVA generator is generally capable of powering it.
Unlike a desktop computer, laptops are designed to be energy-efficient, and their power consumption is significantly lower compared to desktop computers. On average, a laptop may consume around 30 watts to 60 watts. So, a 2.5kVA generator can easily power multiple laptops or a laptop docking station.
6. Small Microwave Oven (up to 700 watts)

7. Power Tools (up to 1000 watts)
Power tools can have varying power requirements depending on their type and usage. In most cases, their power usually ranges from 300 watts to 2000 watt. So, 2.5kVA generators are suitable for running a variety of power tools, provided the power is not beyond 1000 watts.
To mention a few, electric drills, angle grinders, circular saws, jigsaws, and electric screwdrivers, all, typically, have minimal power that a 2.5kVA generator can handle, provided you didn’t abuse the use.
Electric drills for household use typically have power ratings ranging from 500 watts to 1,000 watts. Similarly, angle grinders, commonly used for cutting and grinding, may have power ratings ranging from 500 watts to 1,500 watts. That means you can only use small angle grinders on a 2.5kva gen.
A little higher amongst these tools is the circular saws used for cutting wood and other materials. They may have power ratings ranging from 1,200 watts to 2,000 watts. So, circular saws are not ideal for use with a 2.5kVA generator.
On the other hand, jigsaws, used for intricate cutting, generally have power ratings ranging from 300 watts to 800 watts. And a little similar are the electric screwdrivers. They typically have power ratings ranging from 100 watts to 500 watts. That means a 2.5kVA generator can easily power jigsaws and electric screwdrivers for assembling furniture and other tasks.
For other power tools, make sure you check their power wattage and ensure they are below 1,000 watts before using them on the generator.
8. Small Air Conditioner
If you’re already thinking of the possibility of powering your standard air conditioner with a 2.5kVA generator, you need to go higher. The power unit can only power a small window or portable air conditioner with a low power rating.
Small window air conditioners with a cooling capacity of around 5,000 BTU (British Thermal Units) typically have power ratings ranging from 500 watts to 700 watts. Thus, a 2.5kVA generator can comfortably power these air conditioners.
For the portable air conditioners, they have varying power. While the ones with around 8,000 BTU may have power ratings ranging from 800 watts to 1,200 watts, higher ones with about 10,000 BTU may have power ratings ranging from 1,000 watts to 1,500 watts. That said, a 2.5kVA generator can handle most 8,000 BTU, but it’s important to check the specific power rating before loading it on the generator.
9. Sump Pump
Sump pumps are crucial for managing water in various settings. If you live in an area prone to flooding, a sump pump will be a useful tool to prevent water damage.
Submersible sump pumps, commonly used to prevent flooding in basements, typically have power ratings ranging from 400 watts to 1,200 watts. While a 2.5kVA can comfortably power most residential pumps, it’s crucial to check the specific power rating of the pump to be sure.
Mind you, avoid powering other appliances with a 2.5kva generator when using it to power a big sump pump.
It is important to note that this is not an exhaustive list, and the actual number of appliances that a 2.5 kVA generator can power will depend on the specific wattage of each appliance. It is also important to remember that generators should not be overloaded, so it is always best to err on the side of caution and choose a generator that is larger than you think you need.
What a 2.5kVA Generator Can’t Power
While a 2.5kVA generator is versatile, there are limitations to its capacity. Here are some appliances the generator may struggle to power:
1. Large Air Conditioners
A 2.5kVA generator may struggle to handle large air conditioners due to their higher power requirements during startup and continuous operation. Large air conditioners, especially those with higher BTU (British Thermal Units) ratings, typically have higher power consumption, often exceeding the capacity of a 2.5kVA generator.
Note that the starting wattage, known as the surge or inrush current, is notably higher for air conditioners as they initiate the compressor and other components. Large air conditioners, especially those with capacities above 12,000 BTU, often require power in the range of 1,500 watts to 3,000 watts or more.
Moreover, the continuous power demand during operation and the initial surge when starting can exceed the sustained capacity of a 2.5kVA generator.
2. Water Heaters
Water heaters, especially those designed for larger households or commercial settings, can have high power ratings, typically ranging from 3,000 watts to 6,000 watts or more.
Similar to other appliances with electric motors or heating elements, water heaters experience a surge in power demand when starting up. The starting wattage can be significantly higher than the running wattage. Therefore, it can pose a challenge for a 2.5kVA generator that may struggle to handle such initial surges.
3. Electric Stoves and Ovens
Electric stoves and ovens, particularly those with multiple burners and high-capacity ovens, often have substantial power requirements that may surpass the capacity of a 2.5kVA generator. Their power consumption can range from 1,500 watts to 3,500 watts per burner, and ovens may require 2,000 watts to 5,000 watts or more.
Besides, the combined power demand of multiple burners and an oven can quickly exceed the capacity of a 2.5kVA generator. Note that cooking often involves extended periods of stove and oven operation, and the sustained high power demand during cooking sessions can strain a 2.5kVA generator.
4. Washing Machines and Dryers
Laundry appliances like washing machines and dryers have high-power requirements that a 2.5kVA generator may not meet. Larger washing machines may require 500 watts to 1,500 watts, while dryers can have power requirements ranging from 1,500 watts to 5,000 watts or more.
Given the typical running wattages, a 2.5 kVA generator might be able to handle a washing machine, but starting the motor could overload the generator. So, it’s better not to use them together
Moreover, the combined power demand of a washing machine and a dryer, especially during simultaneous operation, can quickly exceed the capacity of a 2.5kVA generator. And, due to the high starting wattages of most dryers, a 2.5 kVA generator is unlikely to be sufficient to run them without overloading.
Additionally, both washing machines and dryers experience a surge in power demand when starting up. That is to say that washing machines with motor-driven components and dryers with heating elements contribute to higher starting wattages.
Again, this list is not exhaustive. There are several other appliances and power tools that a 2.5kva generator can not power. Just ensure you check the power wattage of the appliances and ensure it’s not beyond 1,500 watts.
Here are some additional factors to consider:
- Number of appliances: Even if an individual appliance seems within your generator’s capacity, using multiple appliances simultaneously can overload it. Always consider the total wattage of all connected appliances.
- Starting surge: As mentioned earlier, some appliances require a higher wattage to start their motors than to run continuously. Factor in the starting surge wattage when assessing compatibility with your generator.
