Most portable pianos and portable keyboards ask you to give something up. Usually it's keys: 49, 61, sometimes 76, with narrow travel-sized action that changes your fingering the moment you sit down.
Pocket Piano doesn't make that trade. 87 full-size keys across seven octaves, 10 mm of travel and nine sensitivity levels, in a body that folds to 40 cm and weighs 6 kg. It is a portable piano in how it moves and a real piano in how it plays.
It runs over eight hours on its own battery, so it works where there is no socket, and it doubles as a USB-C or Bluetooth MIDI controller when you are producing instead of performing.
If most of your playing happens away from home, see how it works as a travel piano.
