This page explains how Watt Guy decides what to cover, how articles are researched, and where the money comes from. It exists because readers should be able to check our incentives before trusting a recommendation.
How topics get chosen
Watt Guy covers power banks, portable power stations, UPS and home backup, batteries, chargers, and solar gear. A topic makes the cut when it answers a real question and the facts can be verified beyond a manufacturer’s marketing claims. Nobody pays to be covered or to be covered favourably.
Sourcing standards
Prices, specifications, measurements, and safety claims come from named sources such as official manuals and technical documents, regulators and standards bodies, or independent published tests. Owner feedback may show recurring problems, but it is identified as owner feedback rather than treated as laboratory evidence.
Hands-on claims appear only when documented work was actually performed. The article will state what was used, what was measured, and the limits of the method. Otherwise, Watt Guy describes the work as verified research and attributes outside measurements to their source.
Honest negatives
Products have tradeoffs. Watt Guy names the drawbacks that affect safety, compatibility, runtime, charging, cost, repairability, or everyday use. If the cheaper option is the better fit, the article will say so.
Affiliate links and independence
Watt Guy does not currently use affiliate links and earns no commission from product links. There are no paid placements or sponsored posts. If the business model changes, the change will be disclosed before it affects the site. See the Affiliate Disclosure for the current status.
How articles get made
Watt Guy may use modern software tools, including AI systems, for research organization, drafting, chart generation, and quality checks. Every article remains responsible for verifiable facts, clear attribution, no invented numbers, and no fake testing claims. Errors are handled under the Corrections Policy.
Updates
Prices change, products are revised or discontinued, and better evidence appears. When an article’s core facts go stale, Watt Guy updates the article or clearly states that it reflects a point in time.
