Tethered Trust

Tethered Trust checks compatibility before a purchase or install: will this part, accessory or device fit, plug in, mount or run with what you already own? Ask about a single item or a whole cart. It covers PC parts and builds, laptop memory and storage, chargers, camera lenses and batteries, power tool batteries, printer ink, appliance filters and installation fit, TV mounts, EV charging, smart home (Matter, Thread, Zigbee) and more. Every answer is one of four decisions: supported, conditional, incompatible or insufficient evidence. Each comes with the rules it checked, caveats, any adapters you'd still need, links to its sources and a signed receipt. When the evidence isn't there, it says so and tells you exactly what to ask, instead of guessing. Data comes from manufacturer spec sheets checked on recorded dates and from public certification registries such as ENERGY STAR and the Matter certification ledger. Products outside the reviewed catalog are read from the manufacturer's page and clearly marked unverified. No account needed. Answers are informational; confirm with the manufacturer before buying.
