Terms of use

Who this is for

PowerStation Size is a free calculator and a library of manufacturer specifications. It is operated by PowerStation Size independent publisher in United States. Using the site means you accept these terms.

Estimates, not a product

Runtime, capacity, surge, and solar figures are planning estimates. They depend on temperature, battery age, inverter losses, and how your device actually draws power. They are not a warranty, a test report, or a promise that a station will start or run your load.

Not medical or electrical advice

A portable power station is not a medical device and is not a substitute for the battery your equipment maker specifies. Never feed a station back into household wiring. Whole-home backup needs a transfer switch installed by a licensed electrician.

Specifications

Each published number is taken from the manufacturer page named on the model record, with a verification date. Manufacturers change pages. If a figure here disagrees with the current manufacturer page, the manufacturer page wins. Email a correction to[email protected].

Your load data

The calculator runs in your browser. Device lists encoded in a shared URL can be read by anyone who has the link. Do not share a link if that list is sensitive. See theprivacy page.

Acceptable use

Do not scrape the catalog to republish it as your own verified database. Do not use the site to give medical or electrical advice to someone else as if it were ours. Do not attempt to overload, deface, or impersonate the site.

Liability

The site is provided as is. PowerStation Size independent publisher is not liable for purchase decisions, outages, equipment damage, or injury that follows from using these estimates. Your sole remedy for a wrong number is a correction on the page.
