How We Research
Every guide on BreakerGuide starts with one question: will this battery backup match the devices you plan to plug into it?
Here is how we answer it.
1. We start with what you plug in
A UPS is sized by its VA and watt ratings, and your devices set how much you need. We check each model's ratings, its outlet count and the type of power it gives, such as simulated or pure sine wave.
When a device like a gaming PC may need a certain kind of power, we say to check both the PC and UPS manuals.
2. We compare specs and features
We look at battery-backed and surge-only outlets, the display, the USB connection, the replacement battery and the warranty terms the maker lists.
When a detail comes from the maker, we say so. Runtime depends on your load and the battery's age, so we give the maker's runtime figures as the maker's numbers.
3. We look at buyer feedback
We read through what buyers report after using a product. We look for patterns, like constant beeping, short runtimes, fan noise or a battery that needs replacing early.
One angry review doesn't sink a product. A pattern does.
4. We score each product
Our score weighs specs, features and buyer feedback against what you're shopping for. A UPS that fits a desktop PC well may score lower in a guide for a router and modem.
Scores spread out on purpose. A 10 is rare.
5. We keep pages up to date
Products change, and some disappear from stores. Models also get replaced and battery part numbers change, so we check each model name before we write about it.
When we update a guide, the "Updated on" date at the top changes with it.
What our picks are not
Our picks are research, not lab tests. We don't claim to have used every UPS we cover, and we don't run our own runtime tests.
A UPS is meant to give you time to save your work and shut down. It isn't a promise against data loss or damage.
Our guides don't replace the maker's manual. For battery changes, follow its steps and recycle old batteries.
A UPS is not a medical power system. For any health device, a refrigerator or a sump pump, follow the device maker's guidance.
