Purchasing the right UPS (uninterruptible power supply) is critical for companies and individuals who rely on computers, servers, and other devices to be operational 24 hours a day, seven days a week.
This is because a power outage, even though it is just for a few minutes, can be disastrous. A sudden shutdown could render servers and files unreachable – or worse, compromised. When the electricity goes out, the best UPS can avert catastrophe by seamlessly converting to battery power to keep the computers running before the main power is restored or you’re able to safely shut down the computer.
Buying the best UPS the budget allows is much more necessary in these turbulent days, when many of us work from home. You could find yourself plugging in a lot of power-hungry gadgets into your home power supply, which might result in power outages or surges. Since your home is unlikely to have the same power backup options as your office, purchasing a UPS for your home may be a smart investment.
The UPS devices we’ve included in this guide cover a wide variety of applications, from small home UPS devices that can hold a router and PC running to big and efficient business UPS devices. As a result, the best UPS gadgets are classified in no specific order.
