The Buying Checklist, at a Glance
Buying a UPS is easy with a plan. Name your goal (ride a blink, save and shut down, stay online), list what you'll protect and add up its watts, then choose line-interactive with pure sine wave, sized so the watts clear your gear with headroom and the battery holds enough runtime. Check for enough battery-backup outlets, shutdown-software support, a user-replaceable battery, and a safety mark like a UL listing. There's a printable 29-page version up top.
Common Questions
1 What kind of UPS should I buy for a home?
A line-interactive UPS with pure sine wave output, sized so its watts cover your gear with headroom, and enough battery-backup outlets. That fits the great majority of homes and offices.
2 How big should it be?
Big enough that its watts comfortably clear the total of what you'll protect, with room to spare, and its battery holds enough minutes for your goal. Our sizing guide walks it through.
3 What features really matter?
For a computer or NAS: shutdown-software support. Always: enough battery outlets, a user-replaceable battery, and a recognized safety mark. A display is a nice bonus.
4 Should I get the fanciest one to be safe?
Usually no — an online UPS is more than most homes need. Right-size to your goal; overbuying wastes money you could spend on runtime or a spare battery.
5 Is a used UPS a good deal?
Often not, because a used one may need a new battery right away. Factor that in. For most folks a new unit with a fresh battery and warranty is the better value.
6 What safety mark should I look for?
A recognized listing such as a UL listing, which means it was tested to a safety standard. A very cheap unit without one is a reason to pass.
Would You Rather I Just Help?
Ready to buy but want to be sure? Tell me your goal, your gear, and your typical outages, and I'll hand you a specific, honest shopping list — no commission, no upsell. $99 flat for an in-home visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
