CableMatch
CableMatch prevents the most common electronics shopping mistake: buying the wrong charger, cable, dock, or adapter. Users scan a device label/port (or select a model), then the app outputs exact compatibility requirements—USB-C PD wattage, cable e-marker needs, HDMI version, Thunderbolt support, barrel size, and safe alternatives. It then shows a short list of verified products from major retailers with clear “will work / won’t work” reasoning, not vague marketing claims. The app also flags risky combos (cheap USB-C cables for laptops, fake fast-charging claims) and suggests minimum specs to avoid overheating or slow charging. Realistically, this wins by focusing on a narrow, high-frequency pain point where returns are common and confusion is high. Monetization can be affiliate revenue plus a small “pro” tier for IT teams managing device fleets.
