We have a modified LD System RJ8 portable 50W PA system.  Comes with wheels and a battery, which lasts around 14 hours.  We replaced the speakers to make music sound better.  We have a microphone clipped to the side using a 3D printed mount, and it has guitar/instrument inputs and either line-in or bluetooth, all mixable.

t-bone wireless microphones for events, conferences and live performances (yes we found a way to make them work for Karaoke). We have 4x handheld microphones like this             and 2x headset mics like this

Our analogue 22 way mixing console is ideal for events, conferences,  bands and parties.  Comes with a (large) road case so "portable".

From Thomann, we have the "Dave" G3 PA kit.  750W of power for small bands, conferences and more.  Includes stands.
