FAQ

A UPS, or uninterruptible power supply, is a device that provides backup power to your electronics in case of a power outage. It works by using an internal battery to supply electricity when the main power source fails, helping prevent data loss and equipment damage.

You can connect computers, networking equipment, servers, gaming consoles, home theater systems, and other sensitive electronics to a UPS. It's important to check the total wattage supported by the UPS to ensure it can handle all connected devices.

To maintain your UPS, keep it in a cool, dry place with adequate ventilation. Periodically test the unit by unplugging it from the wall to ensure it switches to battery power. Replace the internal battery as recommended by the manufacturer.

Yes, most UPS units include built-in surge protection that helps shield your connected devices from voltage spikes and electrical surges in addition to providing backup power during outages.

Most UPS units have indicator lights or alarms that alert you when the battery needs replacement. You may also notice reduced backup time or failure to provide power during outages as signs that the battery is nearing the end of its lifespan.
