This new AC adapter connector and wire is designed to work only with the PARI Trek S Portable Nebulizer System and allows you to plug your Trek S System into any US wall outlet.
Because it instantly converts between 110 and 220 volts, the PARI Trek S AC Adapter may be used in many countries. You will only require a wall plug adaptor, not a voltage converter, if traveling outside of the United States with your Trek S gadget.
