How We Research

Updated on

Every guide on FineOwner starts with one question: will this product work for the person who is shopping for it? For our power station guides, that means the things you plan to run, how long you need them running and where you'll use the unit.

Here is how we answer it.

1. We start with watts and watt-hours

Two numbers do most of the work. Watt-hours say how much energy the battery holds, and watts say how much the unit can run at once.

We check each unit's capacity, its rated output and surge limit, its outlets and its battery type. Then we show how to size one for what you plug in.

2. We compare specs and features

We look at ports, charging options, solar input, weight and the warranty the maker lists. Runtime depends on the load, so we show you how to work it out instead of promising a number.

When a detail comes from the maker, we say so.

3. We look at buyer feedback

We read through what buyers report after using a unit. We look for patterns, like fans that run loud, apps that are hard to use or a unit that doesn't run a device as expected.

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 product that's great for one buyer may score lower in a guide written for another.

Scores spread out on purpose. A 10 is rare.

5. We keep pages up to date

Products change, and some disappear from stores. Makers also rename models, change batteries and swap accessories, so we check each unit's name and details 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 powered every device we write about.

Our guides don't replace the maker's manual.

Follow it for charging, storage, what to plug in and safe use. For medical equipment or wiring a unit into your home, ask the maker or a licensed electrician.

We make no promises about how long any unit will run your devices. When a maker lists a runtime or a rating, we label it as the maker's claim.
