Power Boost
Power Boost extends the AC output from 1200W to 1600W by reducing operating voltage from 230V to 200V. This allows you to run appliances that exceed the standard 1200W output limit.
Important: appliances with built-in voltage protection are not compatible with Power Boost. Power Boost is always active except when the unit is charging from AC.
