USB-C Compatibility Database

Build a consumer-facing web app and browser extension that tells buyers whether a specific device truly charges with USB-C to USB-C, what wattage works, and which chargers or cables are known-good. The core value is reducing returns and eliminating guesswork before purchase.

Why this matters

You are trying to simplify travel and daily charging around one brick and one cable, but the promise breaks when a product has a USB-C port that behaves like an old accessory in disguise. You only discover the problem after it arrives, when your normal charger does nothing and you start swapping cables, ports, and adapters to figure out what is broken. The hardware may be fine in a narrow sense, but the buying experience feels misleading. Existing reviews rarely state whether USB-C to USB-C works reliably, so you end up searching scattered discussions or returning products after the fact.

Differentiation

Existing solutions
Generic marketplace listingsNo-name charging accessoriesMixed-port travel chargers
Our angle
There is no widely trusted software layer that turns messy USB-C compliance behavior into simple buying guidance, compatibility checks, and step-by-step diagnosis for consumers and small hardware teams.

Why This Might Fail

Self-rebuttal — the most important trust signal

  1. 1The market may prefer free forum research over paying for compatibility data unless the convenience gap is dramatic.
  2. 2Coverage may be too sparse early on, making the product feel unreliable before network effects develop.
  3. 3Retailers or review sites could replicate the most useful compatibility content once demand becomes visible.

Evidence Summary

How AI synthesized this insight — no verbatim quotes

The strongest pattern was frustration with products that appear modern but fail with standard USB-C charging setups. Roughly a dozen comments discussed devices that only worked with legacy cable paths, plus repeated returns, travel inconvenience, and workarounds using mixed-port chargers or special adapters. Several participants also emphasized that buyers want one-cable simplicity, which creates strong demand for trustworthy pre-purchase compatibility guidance.
