Teardown: OMENIS 5-Port GaN Desktop Charger with Smart Display — Chengxi Film Capacitors Adopted at Volume
2026-08-13 · Compiled by Best IT Parts from public industry reporting
A recent professional teardown found that OMENIS' 4C1A GaN desktop charger with a smart display is built around multiple Chengxi Electronics capacitors, including one 0.22μF safety-rated X2 capacitor and three additional film capacitors deployed across the power stage. The teardown walks through the charger's internal architecture — input EMI filtering, PFC and flyback stages, and output regulation — highlighting where film capacitors replace electrolytic types to improve ripple handling, reliability, and service life in compact high-density GaN designs. The adoption signals Chengxi film capacitors reaching volume deployment in mainstream GaN desktop chargers. For power adapter OEMs, capacitor distributors, and B2B buyers in the charger supply chain, this is a concrete reference point on film capacitor selection for next-gen desktop charging products.
