3C COMPASS
About 3C Compass
An owner-operated electronics decision lab built around inspectable calculations and practical records.
What the Lab publishes
3C Compass publishes open numerical models for USB-C power, power-bank energy, phone storage growth, laptop capacity, and display-link budgets. A small manual library covers the manufacturer, regulator, seller, and diagnostic facts that a formula cannot establish.
Who operates it
3C Compass is an owner-operated project. The public byline is the organizational name 3C Compass Lab. The site does not invent staff biographies, engineering credentials, laboratory access, product ownership, or physical testing that did not occur.
What is original here
The original contribution is the decision model: measurable inputs, visible equations, intermediate values, market-tier rounding, named calculated scenarios, version records, and explicit uncertainty. Primary sources establish documented constraints; they do not turn an analytical example into a physical test.
How the site is funded
The global site may be funded by clearly identified advertising and, outside the current review cycle, tagged affiliate links. Those programs do not purchase a model result or editorial conclusion. Every useful calculation and manual remains complete without a retailer exit.
