What this site is, and what it is not
PowerStationFacts compares portable power stations using the numbers their makers publish. Every figure on this site is read from an official product page or manual and stored in one shared registry. We do not own these units and we do not run laboratory tests, so nothing here is presented as a measured result.

Where the numbers come from
Capacity, continuous output, surge rating, cell chemistry, cycle life, recharge time, solar input and switchover time all come from the manufacturer: Anker SOLIX, BLUETTI, Jackery, EcoFlow. Each value is stored once, in a single registry, and every page reads from it. That is why the same model shows the same figure everywhere on the site.
When a maker does not publish a value, the page says so. It does not fill the gap with an estimate borrowed from a retailer listing or a review video.
Why there are no test results here
Plenty of sites publish runtime charts without saying where the numbers came from. We would rather be plainly documentary. Comparing published specifications is genuinely useful: it exposes the differences that decide a purchase, such as whether a unit switches over fast enough to keep a desktop alive, or whether its cycle rating is quoted to 80% or to 70% of original capacity.
What it cannot tell you is how a unit behaves in the cold, how loud its fan gets under load, or whether its app is pleasant. For that, look for someone who actually owns one.
Why prices are not shown
Showing a price means committing to keeping it accurate. Amazon's own terms require a visible timestamp on any price refreshed less often than hourly, and access to the pricing interface depends on account eligibility we do not currently hold for this marketplace. Rather than print a number that quietly goes stale, every product links straight to its Amazon listing, where the current price is the one that counts.
A note on cycle ratings
One figure deserves particular care. A cycle rating is only meaningful with its endpoint attached. A unit rated for 4,000 cycles to 70% capacity and one rated for 4,000 cycles to 80% capacity are not making the same promise, and manufacturers do not all use the same endpoint. Wherever this site quotes cycle life, it quotes the endpoint alongside it.
