How we ranked these portable keyboards
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: portable piano keyboard
Count the keys before you buy
Key count decides how much of the keyboard range you can play at once. The RockJam board has 49 mini keys, the Alesis and Casio SA-51 boards have 32 mini keys, and the Casio CT-S200 and Yamaha boards have 61 full-size keys. If you want a smaller board for practice, fewer keys keep the board smaller.
Check battery power for playing anywhere
Battery power decides whether the keyboard plays away from a wall outlet. The RockJam, Casio CT-S200, Alesis and Casio SA-51 boards all run on batteries, while the Yamaha board runs on corded electric power with a power adapter. The RockJam board also takes USB-C power, and the Alesis board takes USB power or 4 AA batteries. If you play away from home, pick a board with battery power.
Compare tones, rhythms and built-in songs
Tones and rhythms decide how many sounds the keyboard offers. The Casio CT-S200 gives 400 tones and 77 rhythms with 60 built-in songs, the Alesis gives 300 voices and 40 demo songs, and the Casio SA-51 gives 100 tones with 50 rhythm patterns and 10 built-in songs. The RockJam board gives built-in tones and beats for early practice. Pick the sound count that matches the styles you play.
