About WattHourLab

WattHourLab is an independent site. It publishes plain-language guides on portable power stations, home backup batteries and solar pairing, for people who want backup power and more energy independence without guesswork.

How guides are researched

• Guides are built from official docs, spec sheets and vendor data: manufacturer spec pages and manuals, and official sources such as the FAA, CDC and Ready.gov.
• Every guide names the exact models it covers, links its sources and shows the date its facts were last checked.
• If a spec cannot be verified from an official source, the guide makes no claim about it and lists it as unverified in its fact-check list, rather than guessing.
• Each guide ends with a fact-check list showing what was verified and what is still open.
• Worked examples use example loads, labelled as examples, not measurements.

Safety

Anything that connects to your home wiring (transfer switches, inlet boxes, smart panels) must be installed by a licensed electrician under local codes and permits. Our home backup pages are background reading, not installation instructions.

EV life

The planned EV life section will hold first-hand posts written by the site owner. Until those are written, the section only lists planned topics.
