How to Choose Ups
Power Capacity
Look for a UPS with enough power capacity for your devices. A unit with at least 500VA is good for basic computers and routers. For more demanding setups, consider 1000VA or higher. This ensures your devices stay powered during outages.

Frequently asked questions
What is a UPS?
A UPS (Uninterruptible Power Supply) provides backup power during outages. It allows devices to keep running, preventing data loss.
How do I know what size UPS I need?
Calculate the total wattage of your devices. Choose a UPS with a capacity that exceeds this total by at least 20%.
Can a UPS protect against power surges?
Yes, most UPS models offer surge protection. This helps safeguard your devices from spikes in electricity.
How long can a UPS keep devices running?
Runtime varies by model. Most UPS units provide between 10 to 60 minutes, depending on the load.
Is it good to leave a UPS plugged in?
Yes, keeping a UPS plugged in ensures it’s charged and ready for use during an outage.
What to look for
Battery Type
UPS models usually use sealed lead-acid (SLA) or lithium-ion batteries. SLA batteries are common and affordable but heavier and bulkier. Lithium-ion batteries are lighter and have a longer lifespan, making them easier to manage.

Warranty Length
Check the warranty length when selecting a UPS. Most models offer warranties between 1 to 3 years. A longer warranty can give you confidence about the product’s reliability.
Cooling System
A good UPS should have a cooling system to prevent overheating. Look for models with fans or ventilation features. This prolongs the life of the unit and maintains performance.
