Our take on the HP 85W92AA Poly Trio 8300 Power Supply With Power Cord/CAT-5 (US)

This is the replacement power supply and CAT-5 cable kit for the Poly Trio 8300 conference phone. It is an OEM HP Poly part, so it matches the original adapter's connector and power output exactly. Buy it if your Trio 8300's adapter was lost, damaged or left behind in another room. Third-party universal adapters can fit the barrel but often ship with the wrong plug or cable, so the genuine kit is the safer route for a single phone.
