Rechargeable battery lasts 8+ hours on stage. Bluetooth MIDI connects wirelessly to backing tracks or external synths. Built-in speaker is surprisingly good for rehearsal. Used at $400-560.
What to check used: The strap system takes practice to balance. Spend 10 minutes adjusting before your first gig.

Compact Keytar Synthesizer · 49 keys, 650+ sounds, mini keys, drum pads, battery powered$200–$280 usedBest for: Performers on a tighter budget or who prefer mini keys

#3
Alesis Vortex Wireless 2
MIDI Keytar Controller · 37 mini keys, 8 pads, 16 assignable knobs, rechargeable, wireless USB$80–$120 usedBest for: Electronic musicians and producers who perform live DAW sets
The Vortex Wireless 2 is a control surface, not a synth. You play it into Ableton, Serum, or any VST. This appeals to producers who want hands-on control on stage instead of laptop-only performance. Mini keys keep it light. Used at $80-120 is a steal.
What to check used: Requires a running DAW or external synth. If your backing setup fails, you have no fallback sounds. Many performers use this alongside a standalone synth for redundancy.
