Testing a supposedly 30W 12/220V mini Inverter

Short Test of these cheap supposedly 30w 12V to 220V mini Inverters. I wanted to know what the Transformer is capable of, bcs I want to use it in a Power Supply Design.
When running in CW in a Mosfet driven ZVS Configuration with 0.68uF Resonant Capacitor in Parallel : ca. 12-15W (Cold Running), Max = ca.17-20W (Warming up considerably)
