We do not treat Amazon copy as evidence. Product pages often overstate wattage, hide tip compatibility, or mix old and new model photos. Every recommendation is checked against manufacturer documentation, structured spec data, and practical bench behavior reported by electronics users doing the same work the tool is recommended for.
When a review uses direct measured values, the review explains the setup. When the evidence comes from documentation or repeatable owner reports instead of direct measurement, the review should make that clear rather than implying lab data we do not have.
