We present a hybrid trapping platform that allows us to levitate charged nanoparticle in high vacuum using either optical fields, radio-frequency or combination thereof. Our approach combines an dipole trap with linear Paul while maintaining large numerical aperture (0.77 NA). detail controlled transfer procedure use the as safety net recover particles lost from at vacuum. The presented adds toolbox of levitodynamics and represents important step towards fully controllable dark potentials, providing control absence decoherence due photon recoil.
