Frequently Asked Questions
What size UPS do I need for a home office?
Add up your equipment's wattage: a typical PC (200-400W), monitor (30-50W), and router (10-15W) totals 240-465W. Choose a UPS rated at 1.5-2x your total load. A 750VA/450W UPS handles most home offices. For gaming PCs or dual monitors, step up to 1000-1500VA.
Simulated sine wave vs pure sine wave UPS?
Pure sine wave UPS units produce clean power identical to wall power, which is essential for PCs with Active PFC power supplies (most modern computers). Simulated sine wave is cheaper and works for routers, modems, and basic electronics. When in doubt, choose pure sine wave for computers.
How long do UPS batteries last?
UPS batteries last 3-5 years before needing replacement. Replacement batteries cost $30-80 and are easy to swap in most units. The UPS itself lasts 7-10+ years. Run a self-test monthly (most units do this automatically) to verify battery health.
