This UPS produces a square wave output, and not a simulated sine wave. Feeding square waves to computer's PSU usually results in loss power efficiency and, in some cases, can lead to premature failure. Nevertheless, the majority of PSUs available on the market can tolerate square waves. Make sure to check your PSU’s manual if it supports a square wave output before buying this UPS. See More
This UPS is rated at 225W, which may seem insufficient at first. However, a business desktop computer requires only about 150W of power to run. Adding a common 24W monitor would result in a total of approximately 174W of power consumption, leaving you with a safety margin of 50W. See More
If there's ever a need to replace this unit's battery, a replacement battery is quite easy to find online. As for the replacement operation itself, it's very simple and requires virtually no technical knowledge: you just need to remove the battery cover, take out the battery, unplug the connectors, and then the opposite steps in reverse order for the new battery.

This UPS is rated at 75W, which is enough for networking equipment, but insufficient for even a basic desktop computer. The APC BGE70 will easily supply plenty of power to a Wi-Fi router and still have room for a 24-port gigabit switch or any other low-power networking equipment, but not more than that. See More
Designed to be an on-the-desk UPS, you can undock the battery pack easily when going on trips, then dock it back for charging once you get home. Keep in mind that taking the battery out of the device will turn the UPS into a simple surge protector, leaving your equipment vulnerable to power outages. See More
In terms of hardware and electrical design, a line-interactive UPS (with automatic voltage regulation) is considerably more expensive than a simple standby UPS (without automatic voltage regulation). For around $88.89, a line-interactive UPS is quite a bargain. Line-interactive topology allows the unit to regulate voltage during surges or brownouts without switching to battery, effectively reducing the chance of premature battery failure. See More
