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: mini piano keyboard for computer
Count keys before you choose
Key count decides how much music fits under your hands. The RockJam has 49 keys, the Alesis has 32 keys, and the Synido has two octaves with a 4-octave shift. The SR has 78 QWERTY keys for typing, not piano keys, so check the key type as well as the count before buying.
USB, MIDI and power options
Computer keyboards connect over USB, and piano keyboards add MIDI for music software. The RockJam runs on USB-C or batteries, the Alesis runs on USB or 4 AA batteries with USB-MIDI, and the Synido runs on AAA batteries or USB-C with MIDI over USB-C. The SR is a wired USB keyboard, so it needs a USB port and no batteries.
Speakers, headphones and lessons
Built-in speakers let you play without extra gear, and a headphone jack keeps practice quiet. The RockJam and the Alesis both have built-in speakers and a headphone jack, and the Synido has a 3.5mm audio jack. The Alesis adds lessons from Melodics and Skoove, and the RockJam adds Simply Piano app content.
