With frequent power outages, Ukrainians are choosing between a generator and a UPS: What you need to know

Generators are designed for providing power over extended periods, particularly during long-term outages.
Generators are designed for providing power over extended periods, particularly during long-term outages.

Considering Russia's devastation of Ukraine's energy infrastructure after multiple mass attacks, ensuring an uninterrupted power supply for your electronics is now more critical than ever.

Ukrainians are now considering whether to move to something like a generator or uninterruptible power supply (UPS).

Here’s what you need to know about each option.

Uninterruptible Power Supply (UPS)

A UPS, or Uninterruptible Power Supply, is designed to provide backup power to your equipment when the main power source fails or becomes unstable.

This system stores energy chemically in a battery, which charges when power is available from the grid.

Key features of a UPS:

  • Provides instant power transfer to connected devices when an outage occurs

  • Protects sensitive electronics from voltage fluctuations and short-term power outages

  • Supplies power for a limited duration, ranging from a few minutes to a few hours, depending on the model

  • Contains built-in batteries that keep essential devices running long enough for you to either safely shut them down or switch to an alternative power source

The UPS is ideal for protecting delicate electronics from power disruptions and ensuring they can continue running seamlessly in case of short-term outages.


Generators are designed to provide power over extended periods, particularly during long-term outages. They are suitable for larger set-ups such as homes, businesses, and other institutions.

Key features of a generator:

  • Capable of running for prolonged periods, so long as there is a fuel supply

  • Converts mechanical energy into electrical energy using fuel, such as diesel or gasoline

  • Requires a short start-up period, meaning there is a brief delay before power is restored

  • Needs regular maintenance and fuel replenishment, and can be quite noisy, which might disturb you and your neighbors

Generators are best for scenarios where you need to maintain power for extended periods, making them a solid choice for larger facilities or situations where power outages are prolonged and frequent.

Making the right choice

When deciding between a UPS and a generator, consider the nature and duration of power interruptions you expect to face:

  • For immediate, short-term power needs: A UPS is optimal for ensuring that sensitive equipment continues to run without interruption. It's perfect for bridging the gap during brief outages and protecting against power surges.

  • For prolonged outages: If you have reliable access to fuel and are prepared for regular maintenance, a generator is more suitable. It offers extended power supply, though with a slight delay in activation and potential noise issues.

Ultimately, your choice will depend on your specific power needs and the conditions of your environment.

If quick, seamless power transition is crucial for you, go with a UPS. For sustained power during longer outages, a generator is the way to go.
