5 Best Uninterruptible Power Supplies

An Uninterruptible Power Supply (UPS) provides a steady electrical current to electronics or electrical equipment in the event of a power failure thanks to an onboard rechargeable battery. It also provides a limited amount of protection against power surges that can fatally damage electronics. And with multiple outlets, a UPS can power several devices at once. As great as this sounds, the UPS isn’t infallible. Plugging in too many appliances or electronics and using a UPS that isn’t rated to handle high-power devices can damage the UPS over time so that it doesn’t work correctly when an emergency strikes and the power goes out.
